Smartphones xperia z5 dual. Smartphones Sony Xperia Z5 series

World's first 4K smartphone

At IFA 2015 in Berlin in autumn, Japan's Sony Mobile Communications (“Sony Mobile”) unveiled the fifth generation of its flagship smartphone family: the Xperia Z5, Xperia Z5 Compact, and the world's first smartphone with a 4K display, the Xperia Z5 Premium.

The “basic” smartphone of the new line, the Xperia Z5, has now come to the turn of the most technically interesting model of this trinity, a device with an extremely high screen resolution, which the developers themselves call “4K”. We will consider the screen that is of great interest in detail in the corresponding section, but otherwise it is worth noting that the Z5 Premium differs little from the main Z5 model, but there are still some differences, including even in the appearance of the novelty. It is with them and with the main characteristics that we, perhaps, will begin.

Appearance and usability

By general view, in terms of design as a whole, the Z5 Premium version almost exactly repeats its fellow in the line. Both models differ from their predecessors in having flatter side bezels, a difference that is striking as all previous Xperia Z smartphones had a much more bulging and rounded bezel.

Here, the frame is made of metal, and, according to Sony, it's not even aluminum, but real steel. The most noticeable difference between the novelty and the usual Z5 is the back surface of the case: if the Z5 used matte coated glass, the Z5 Premium uses the usual transparent glass with a mirror substrate.

This has its pluses and minuses. There is no doubt that fingerprints are more visible on smooth glass. And while the Z5's matte finish is much more slippery to hold in your hand, the Z5 Premium doesn't have that problem.

However, the Premium version has noticeably grown in size, including the thickness of the case, although with such dimensions, the thickness of 7.8 mm still seems quite small. Traditionally, there are no complaints about the quality of materials and assembly, Sony does not give cause for concern in this regard. The smartphone is very solidly tailored, looks and feels solid and reliable product, in the corners there are familiar inserts of painted polycarbonate to dampen the impact energy when falling.

The only complaint is traditionally associated with the same corners: in Sony devices they are very slightly rounded in plan, so the smartphone takes up more space in pockets and sometimes unpleasantly rests on the body, although there is no technical need for such sharp corners, this is purely a design decision. It is quite possible to round them more strongly, as most manufacturers do - then the overall shape of the case would become more interesting than such a simple rectangle drawn on a ruler.

Otherwise, there are no noticeable differences from previous Sony models. Card slots are usually covered with a cover with a rubberized gasket, since the device has been assigned an IP65/68 protection class. As before, this does not mean at all that you can swim and take pictures underwater with a smartphone, since the official signature on the company's website literally reads: “The device is not allowed to be completely submerged under water, and also not to be exposed to sea, salt, chlorinated water and such liquids. like liquor."

SIM-cards are installed in the side slot, driving into it on a plastic tray, which is equipped with compartments for two Nano-SIM cards. Another separate slot is for a microSD memory card. As is the case with the regular Z5, the Z5 Premium is available with single or dual SIM versions.

The hardware buttons are located on the opposite side, there are traditionally three of them, as Sony continues to support the idea of ​​a dedicated photo button. Two buttons are ordinary, sticking out of the case and, it should be noted, quite hard, but the third one is completely flat, you can’t feel it blindly. The fact is that in the new generation of the Xperia Z family, such a convenient and becoming standard unlock tool as a fingerprint scanner has appeared. It also supports the FIDO standard - fingerprint authorization for online payments. True, the scanner platform is limited by the width of the power button embedded in the side face, so you will have to get used to working with a scanner of such an unusual shape at first.

The front panel is habitually covered with a kind of "tempered glass", the manufacturer of which Sony traditionally does not disclose. The glass has two narrow cutouts at the top and bottom for sound output from the speakers, for which proprietary S-Force Front Surround technology is implemented.

Also on the front panel at the top are sensors, a front camera and an LED event indicator. The operation of the indicator is adjusted by the user in the section on sound in the system settings. There are no touch hardware buttons at the bottom under the screen.

The back side, as usual, is reserved for the camera module, which, unlike many modern flagships from other manufacturers, does not protrude beyond the surface of the case. Nearby is a flash, which for some reason Sony is in no hurry to make a double one - again, unlike most other manufacturers.

At the bottom there is a familiar Micro-USB connector that supports the USB 2.0 specification and a kind of connection of external devices in USB OTG mode, which must first be initiated by an independent device search and manual connection. Here, next to it, there is a very rare for today, but useful fastening for a strap.

The top end traditionally contains only a headphone jack, and nothing else. I would like to see in Sony devices someday an infrared transmitter for controlling home appliances, this can be very useful.

As for the colors of the case, this time there were no bright and unusual colors. The Sony Xperia Z5 Premium comes in three color options: light gray (“mirror chrome”), full black, and gold, among which, oddly enough, gold looks the most impressive. It should be noted that in the case of the light gray version, only the color of the back wall and sidewalls changes, while the front panel still remains black.

Screen

The Sony Xperia Z5 Premium smartphone is equipped with touch screen IPS. The physical dimensions of the display are 68 × 121 mm, the diagonal is 5.5 inches. At the same time, the screen resolution is 3840 × 2160, the dot density is approximately 806 ppi. Sony claims that this pixel density is 10 times that of Full HD TVs and twice that of most smartphones. Compared to Full HD, the resolution of 4K (Ultra HD) is twice as high on each side, that is, in such a screen there are four times more dots. Note that some tests, including AnTuTu, determine that the screen resolution of the Xperia Z5 Premium is not 4K, but Full HD (1920 × 1080).

The frame around the screen looks standard: its width is only about 3 mm on the sides and 16 mm on the top and bottom. With such a large overall dimensions of the case, such a frame certainly cannot be called wide.

The display brightness is automatically adjusted based on a light sensor. There is also a proximity sensor that blocks the screen when you bring the smartphone to your ear. Multi-touch technology allows you to handle 10 simultaneous touches. Operation modes with gloves and wet fingers are supported.

Detailed examination using measuring instruments held by the editor of the sections "Monitors" and "Projectors and TV" Alexey Kudryavtsev. Here is his expert opinion on the screen of the test sample.

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are slightly better than the screen of the Google Nexus 7 (2013) (hereinafter simply Nexus 7). For clarity, here is a photo in which a white surface is reflected in the off screens of both devices (Sony Xperia Z5 Premium, as you can easily determine, on the right, then they can be distinguished by size):

Both screens are dark, but the Sony screen is still slightly darker (its brightness in the photo is 105 versus 108 for the Nexus 7). Tripling reflected objects in Sony screen Xperia Z5 Premium is very weak, this indicates that there is no air gap between the outer glass (it is also a touch sensor) and the matrix surface (OGS type screen - One Glass Solution). Due to the smaller number of borders (glass/air type) with very different refractive indices, such screens look better with strong external illumination, but their repair in case of cracked external glass is much more expensive, since the entire screen has to be changed. On the outer surface of the screen there is a special oleophobic (grease-repellent) coating (very effective, even better than the Nexus 7), so fingerprints are removed much easier and appear at a slower rate than in the case of ordinary glass.

With manual brightness control and with a white field displayed in full screen, its maximum value was about 605 cd / m², and the minimum - 4.6 cd / m². The maximum value is very high, and given the excellent anti-reflective properties, in bright daylight and even in direct sunlight, the image on the screen should be clearly distinguishable. In complete darkness, the brightness can be lowered to a comfortable level. There is an automatic brightness control based on the light sensor (it is located to the right of the logo on the front panel). In automatic mode, when the ambient light conditions change, the screen brightness both increases and decreases. The operation of this function depends on the position of the brightness control. If it is at maximum, then in complete darkness the auto-brightness function reduces the brightness to 22 cd / m² (normal), in an artificially lit office (about 400 lux) it sets it to 400 cd / m² (too high), in a very bright environment (corresponds to lighting on a clear day outdoors, but without direct sunlight - 20,000 lux or a little more) increases to 610 cd/m² (even a little higher than with manual adjustment). If the brightness slider is at half the scale (it is very non-linear - after 50% the brightness goes up sharply as the setting is increased), then the screen brightness for the three conditions indicated above is as follows: 13, 210 and 520 cd / m² (suitable values). If the brightness control is set to a minimum - 7, 18, 440 cd / m² (only the average value is greatly underestimated). As a result, the auto-brightness function works absolutely adequately, and it is possible to adjust the nature of the brightness change to the user's requirements. Significant backlight modulation appears only at very low brightness levels, but its frequency is high, on the order of 2.3 kHz, so even in this case there is no visible screen flicker (but can possibly be detected in a test for the presence of a stroboscopic effect).

This screen uses an IPS type matrix. Micrographs show a typical IPS subpixel structure:

For comparison, you can see the gallery of microphotographs of screens used in mobile technology.

However, the subpixels themselves are located unconventionally - typical columns go in the horizontal direction, but in each of the columns the triad of subpixels is shifted vertically by one subpixel, first up, and down three columns later. Note that we have already seen a similar arrangement of subpixels in the case of Lenovo K3 Note. As a result, the ratio of horizontal columns to vertical triads is 3 to 2, the actual vertical resolution is 1/3 less than the horizontal one. Here and below, the landscape orientation of the screen is meant. That is, the dots (RGB triads) on the screen are actually only 3840 by 1440. At the same time, the manufacturer writes about the Sony Xperia Z5 Premium: “4K UHD display (3840 × 2160)”.

Additional tests have shown that, in principle, not every application is generally capable of displaying an image in this conditional 4K resolution. For example, MX Player, FIV, Google Photos output exclusively in Full HD resolution, that is, 1920 by 1080 pixels (the smartphone itself scales to the screen resolution), and only the image demonstrator of Sony itself displays a picture in 4K resolution (perhaps a regular video player Sony knows how to do it too). Here is such a limited "4K", not for everyone. Well, we found the program, let's consider the features of the output using the example of a vertical and horizontal world with black stripes one pixel thick through a white gap also one pixel. The original test image is available at this link, the world is in the center. Here is her fragment:

With vertical (on the right side) stripes, everything is fine - clearly, pixel by pixel. With horizontal ones (on the left side), everything is worse, since dark gaps are only one subpixel thick and visually the world is seen simply as a gray field. On the vertical, if desired (and with the help of a magnifying glass), the strips can be considered. In addition, at the bottom, at the beginning of the horizontal world, instead of a strip, some kind of mess is displayed - a conversion error into the resolution of a strange matrix. However, formally the black-and-white resolution of 3840×2160 pixels is still implemented. Is there a horizontal black bar? There is! It will no longer be possible to sue Sony for cheating, and no one explicitly promised to implement a color resolution of 3840 × 2160 pixels. However, these are all nit-picking, the screen resolution is still prohibitive.

The screen has good viewing angles without hue inversion and without significant color shift even at large deviations of the gaze from the perpendicular to the screen. For comparison, here is a photo in which the same images are displayed on the screens of the Nexus 7 and Sony Xperia Z5 Premium, while the brightness of the screens is initially set to about 200 cd / m² (on a white field in full screen), and the color balance on the camera is forcibly switched to 6500 K. White field perpendicular to the plane of the screens:

Note the good uniformity of brightness and color tone of the white field. And a test picture:

The colors on the Sony Xperia Z5 Premium screen are oversaturated, skin tones are heavily redshifted, and the color balance is noticeably different from the standard. Now at an angle of about 45 degrees to the plane and to the side of the screen:

It can be seen that the colors have not changed much on both screens, the contrast has remained at a good level. And the white box:

The brightness at an angle for both screens has noticeably decreased (at least 5 times, based on the difference in shutter speed), but in the case of the Sony Xperia Z5 Premium, the brightness drop is slightly larger (brightness in photos is 232 versus 235 for Nexus 7). The black field, when deviated diagonally, is not highlighted very strongly and acquires a purple hue. The photos below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is the same for the screens!):

And from another angle:

The black box on the Nexus 7 is still a little darker at the corners. When viewed perpendicularly, the uniformity of the black field is excellent:

Contrast (approximately in the center of the screen) is high - about 1060:1. The response time for the black-white-black transition is 26 ms (16 ms on + 10 ms off). The transition between grayscale 25% and 75% (according to the numerical value of the color) and back takes a total of 35 ms. The gamma curve constructed from 32 points with an equal interval according to the numerical value of the shade of gray did not reveal a blockage either in the highlights or in the shadows, and the indicator of the approximating power function got 2.40, which is higher standard value 2.2, however, this does not matter, since the real gamma curve deviates noticeably from a power law:

This is due to the presence of an aggressive dynamic adjustment of the brightness of the backlight in accordance with the nature of the displayed image (brightness decreases on dark ones). As a result, the resulting dependence of brightness on hue (gamma curve) does not correspond to the gamma curve of a static image, since the measurements were carried out with sequential grayscale output almost on the entire screen. For this reason, we carried out a number of tests - determining contrast and response time, comparing black flare at angles - when displaying special patterns with a constant average brightness, and not monochromatic fields in full screen. In general, such a non-switchable brightness correction does nothing but harm, since reducing the brightness in dark images reduces the visibility of gradations in the shadows under ambient light conditions, and constant brightness jumps are very annoying. That is, the benefits of this function are zero, only harm.

The color gamut is noticeably wider than sRGB:

Let's look at the spectra:

They are very atypical for top Sony mobile devices. Apparently, this screen uses LEDs with a blue emitter and a green and red phosphor (usually a blue emitter and a yellow phosphor), which, in combination with special matrix light filters, allows you to get a wide color gamut. The red phosphor apparently uses so-called quantum dots. Unfortunately, as a result, the colors of images - drawings, photographs and films - oriented to the sRGB space (and the vast majority of them) have an unnatural saturation. This is especially noticeable on recognizable shades, such as skin tones. The result is shown in the photo above.

The balance of shades on the gray scale is mediocre, since the color temperature is much higher than the standard 6500 K, and the deviation from the blackbody spectrum (ΔE), although not very large, jumps noticeably from hue to hue. But at least the variation in color temperature is small. (The dark areas of the gray scale can be ignored, since the color balance does not matter much there, and the measurement error of color characteristics at low brightness is large.)

This smartphone has the ability to correct the color balance by adjusting the intensities of the three primary colors.

What we tried to do, the result is data signed as Heat on the charts above. As a result, we corrected the color temperature and at least lowered ΔE on a white field. This is a good result, but the variation in ΔE has increased, and the brightness (as well as contrast) has greatly decreased - from 600 to 380 cd/m². And such a correction did not reduce the oversaturation of colors. If someone still finds the image on the screen of this smartphone not “bright” and “colorful” enough, then you can turn on the corporate mode X-Reality for mobile.

The result is shown below:

Saturation and contour sharpness are increased by software, and there are fewer distinguishable gradations of shades in the area of ​​saturated colors. But the picture - yes, became brighter. There is also an extreme Extreme brightness mode, in which the trend of "improvement" of the image reaches its peak. Here's what we got:

Let's summarize. The brightness adjustment range of this screen is very wide, anti-glare properties are excellent, which allows you to comfortably use your smartphone both on a sunny day on the beach and in complete darkness. It is permissible to use the mode with automatic brightness adjustment, which works absolutely adequately. The advantages also include a very effective oleophobic coating, the absence of an air gap in the layers of the screen and flicker, moderate black lightening when the gaze deviates from the perpendicular to the screen surface, and excellent black field uniformity. The disadvantages are aggressive dynamic brightness adjustment. Everything is very bad with color reproduction, the colors are oversaturated (skin tones are especially affected), the color balance is poor. The presence of appropriate adjustments allows you to slightly correct the balance, but at the expense of a very strong decrease in brightness (and contrast). Nevertheless, taking into account the importance of the characteristics for this particular class of devices (and the most important thing is the visibility of information in a wide range of external conditions), the screen quality can be considered high. It is better not to watch movies and photographs on this and not show it to anyone, but the text or, for example, maps will be clearly visible.

Sound

The sound of the novelty seemed to us less impressive than that of the same Xperia Z5, although, perhaps, this is a shortcoming of a particular test sample - after all, this is not a serial smartphone from the store. In any case, the sound of the Sony Xperia Z5 Premium is not impressive. Two stereo speakers are located at the top and bottom of the front panel, the sound output is implemented through two barely visible slots, due to which it is possible to realize surround sound, here called S-Force Front Surround. The sound is not bad, clear, but still deaf and not powerful enough and loud - waterproof pads affect.

The sound is better in headphones, but it clearly falls short of the quality of the same Oppo. The sound is bright, loud, but still does not have the full breadth of the frequency spectrum, and crystal clearness too. impurities extraneous noise are audible, the maximum volume level is not excessive, it is barely enough for comfortable listening, there is no desire to lower the slider lower.

The device uses its own branded player to play music compositions, which has suddenly ceased to be called Walkman. Otherwise, everything is familiar here: the user is traditionally given the choice between manual adjustment and automatic optimization of all sound parameters using the comprehensive ClearAudio + function. It includes a lot of various technologies, you can read more about this on dedicated to sound technologies used in all modern top-end smartphones of the manufacturer.

There is an FM radio in the smartphone; there is no automatic recording of telephone conversations from the line using standard tools.

Camera

The Sony Xperia Z5 Premium features the same two 23MP and 5MP digital camera modules as the regular Z5. The front-facing 5-megapixel Exmor R module is equipped with a 25mm wide-angle G Lens with f / 2.4 aperture and fixed focus, it does not have its own flash. The front camera, like the main one, can operate in manual and automatic shooting control modes. The developers emphasize that here for the video there is a SteadyShot electronic stabilization function with Intelligent Active Mode. The camera also supports HDR mode, can recognize a smile and add a “soft skin effect”. The camera does a good job of taking selfies.

The main camera is equipped with the same latest 23-megapixel Sony Exmor RS module for mobile devices with a 1/2.3-inch sensor and a wide-angle G Lens (24mm) with f/2.0 aperture, hybrid autofocus and single-section burst LED flash. Autofocus is fast, using hybrid autofocus technology that combines the capabilities of contrast and phase focusing technologies: the first is responsible for accuracy, and the second for speed. And with focus points spread across the entire viewfinder, it takes significantly less than a second (0.03 s) to bring your subject into focus anywhere in the frame.

Mention the Bionz image processor, in addition, the technology for shooting in low light conditions has been improved, which provides better photos without distortion and blur at night or in the dark. All Xperia Z5 series smartphones have received an updated version of SteadyShot stabilization technology with Intelligent Active Mode, providing smooth stabilization without distortion. And, of course, do not forget that Sony is practically the only manufacturer that still installs a separate hardware camera control button in its smartphones.

In manual shooting control mode, you can set ISO, white balance, change the type of focus. There is a five-fold digital zoom, carried out using Clear Image scaling technology.

In addition, the settings traditionally contain a lot of additional modes, including entertaining ones, such as, for example, an augmented reality mode called AR effect, which makes it possible to combine real shots with animation. Recently, the choice of options for AR has been greatly expanded. Some of the shooting settings can be passed to third-party applications for control via the Camera2 API, but RAW recording is not supported.

The camera can shoot video in a maximum resolution of 4K, there is also a shooting mode at 60 frames per second. By the way, from your videos shot in 4K, you can choose the frames you like and save them as 8-megapixel photos. It looks something like this:

The camera copes well with shooting video in all the listed modes, the sound is recorded cleanly and efficiently, the noise reduction system copes with its tasks adequately. Thanks to the SteadyShot technology with Intelligent Active Mode, shooting on the move is very smooth, this is truly one of the strongest points of Sony's mobile cameras.

• Clip #1 (34 MB, 1920×1080 @60 fps)
• Video #2 (129 MB, 3840×2160 @30 fps)

	The number plate of the closest car is distinguishable.
	The white balance is periodically lost, and blur zones appear in the corners.
	Excellent sharpness in the central part of the frame, but it falls off towards the corners.
	Good detail in the background in the central part.
	Excellent sharpness and detail.
	Not bad sharpness in the field and according to the plans, it drops a little in the corners.
	The camera copes with macro photography.

We also tested the camera on a laboratory bench according to our methodology.

As already noted, the Premium version is not much different from the regular Z5. This also applies to the camera. Despite the shortcomings listed above, the camera is the same as in the Z5, but do not forget that its best qualities appear when shooting at 8 megapixels. In this case, blurry corners can be avoided and the overall sharpness of the image can be improved. However, central part and looks good on 20-megapixel shots, and sometimes the camera does a good job of processing the entire field.

Some of the roughness inherent in the first firmware of new Sony smartphones can still be found here, but they practically disappear when switching to shooting at 8 megapixels. The laboratory test does not allow to prove the identity of the Z5 and Z5 Premium cameras, however, the firmware of the latter clearly does not look final, which is why the images show some artifacts that make such a difference. As a result, we can conclude that the camera will cope well with many scenarios.

Telephone part and communications

The smartphone can operate in most bands of 2G GSM and 3G WCDMA networks, and also has support for fourth-generation LTE Cat.6 FDD networks, that is, this device provides a theoretical download speed of up to 300 Mbps. At the same time, the smartphone has support for all three of the most common LTE bands among domestic operators (B3, B7 and B20). In practice, with the SIM card of the MTS operator in the Moscow region, the smartphone was confidently registered and worked in 4G networks. The quality of signal reception does not cause any complaints, the device confidently maintains communication indoors and does not lose the signal in areas of poor reception. The list of the main frequency bands supported by the device in Russia is as follows:

• LTE FDD: 800/850/900/1800/2100/2600 MHz
• WCDMA: 850/900/2100 MHz
• GSM: 850/900/1800/1900 MHz

The device also has support for Bluetooth 4.1, NFC, dual-band Wi-Fi (2.4 and 5 GHz) and 2 × 2 MIMO speed mode, Wi-Fi Direct, you can organize wireless hotspot access via Wi-Fi or Bluetooth channels. The Micro-USB connector supports the USB 2.0 specification and the connection of external devices in USB OTG mode, but for this you need to manually start searching for devices through a special item in the settings.

The navigation module works with GPS (A-GPS), Glonass and Beidou (BDS). There are no complaints about the speed of the navigation module, the first satellites are detected during a cold start within the first tens of seconds. The smartphone is equipped with a magnetic field sensor, on the basis of which the compass of navigation programs functions.

The phone application supports Smart Dial, that is, while dialing phone number immediately carried out and the search for contacts. Text input is supported by seamless sliding from letter to letter (Swype), and virtual keyboards can also be reduced in size and brought closer to one of the edges of the display for ease of control with the fingers of one hand. The look and organization of the keyboard itself is traditional for Sony smartphones, you can choose from several options. The so-called "small applications" mode allows you to display some regular programs, such as a calculator, a timer, a calendar, and even a browser, in the form of separate small resizable windows. You can open several such windows, that is, in fact, this is such a multi-window mode, but not for any application.

The smartphone supports two SIM cards, but only the data transfer function can be linked to a specific card, and for voice calls and text messages it is necessary to select the SIM card each time in the corresponding interface when sending. In general, this does not cause irritation at all, but someone may lack such obvious functionality as the initial binding of certain functions to specific cards.

SIM-card slots are equivalent in their capabilities, high-speed data transfer in 3G (4G) networks is supported by a card in any slot, switching is carried out directly from the menu without the need to physically change slots. Working with two SIM-cards is organized according to the usual Dual SIM Dual Standby standard, when both cards can be in active standby mode, but cannot work at the same time - there is only one radio module.

OS and software

In terms of the software platform, there are no differences from the regular version of the Z5. Here, the same fifth version of Google Android (Lollipop 5.1.1) with its own shell is used as the operating system. The shell is well known from previous generations of Sony smartphones, there are no noticeable differences from model to model, although something is still changing in small things. For example, here, as in the usual Xperia Z5, the usual navigation panel that slides out on the left in the application menu suddenly disappeared. The home screen on the far left now contains a large widget called What's New, which offers announcements of the most interesting (according to developers) programs and games. The Small Applications menu, called up in the same place as the menu of recently opened programs, has remained in its place, but appearance it has changed, although the functionality remains the same. In general, Sony developers do not introduce drastic changes to their interface so that the owner of any of the old models of the flagship Xperia series can easily "change" to a newer model.

Performance

The hardware platform of the Sony Xperia Z5 Premium is based on the familiar 8-core Qualcomm Snapdragon 810 SoC. This 64-bit SoC is made on a 20 nm process technology and includes four powerful 64-bit ARM Cortex-A57 cores up to 2 GHz, which are complemented by four simpler 64-bit Cortex-A53 cores up to 1.5 GHz, providing high power efficiency or performance depending on specific tasks.

The Adreno 430 video accelerator is responsible for processing graphics in the SoC. random access memory smartphone is 3 GB. The user initially has access to about 21 GB of free flash memory out of a total of 32 GB. The memory can be expanded with microSD cards up to 200 GB, in practice our 128 GB Transcend Premium microSDXC UHS-1 test card was recognized by the device. It also supports connecting external devices to the USB port in OTG mode, but for this you need to manually start the search for devices through the section in the settings.

And yet, the top-end Qualcomm Snapdragon 810 platform is quite capable of competing with other modern flagship alternatives such as HiSilicon Kirin 935 and MediaTek MT6795. In graphics tests, the Snapdragon 810 GPU shows results that are no less than those of the listed SoCs. At the same time, the Snapdragon 810 is quite a bit inferior in everything to the currently leading Exynos 7420 (represented in the tables by a smartphone Meizu Pro 5).

In any case, the Sony Xperia Z5 Premium smartphone is at the level of modern flagships in terms of its performance, and its hardware capabilities will definitely be enough for a couple of generations to perform any tasks, including demanding games.

Testing in the latest versions of AnTuTu and GeekBench 3 comprehensive benchmarks:

For convenience, we have summarized all the results obtained by us when testing a smartphone in the latest versions of popular benchmarks in tables. Several other devices from different segments are usually added to the table, also tested on similar latest versions of benchmarks (this is done only for a visual assessment of the obtained dry numbers). Unfortunately, within the framework of one comparison, it is impossible to present the results from different versions of benchmarks, therefore, many worthy and relevant models remain “behind the scenes” - due to the fact that they once passed the “obstacle course” on previous versions test programs.

Testing the graphics subsystem in 3DMark gaming tests, GFXBenchmark and Bonsai Benchmark:

When testing in 3DMark for the highest performing smartphones, it is now possible to run the application in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (due to which the speed can rise above 60 fps).

Browser cross-platform tests:

As for benchmarks for assessing the speed of the javascript engine, you should always make allowances for the fact that the results in them depend significantly on the browser in which they are launched, so that the comparison can only be truly correct on the same OS and browsers, and this possibility is available when testing not always. In the case of Android OS, we always try to use Google Chrome.

thermal images

Below is a thermal image of the back surface taken after 10 minutes of running the GFXBenchmark battery test:

Heating is strongly localized in the upper part of the device, which apparently corresponds to the location of the SoC chip. According to the heat chamber, the maximum heating was 45 degrees (at an ambient temperature of 24 degrees), which is significantly higher than the average value in this test for modern smartphones.

Video playback

To test the "omnivorous" when playing video (including support for various codecs, containers and special features, such as subtitles), we used the most common formats, which make up the bulk of the content available on the Web. Note that for mobile devices it is important to have support for hardware video decoding at the chip level, since it is most often impossible to process modern versions using processor cores alone. Also, do not expect everything from a mobile device to decode everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it. All results are summarized in a single table.

According to the test results, the subject was not equipped with all the necessary decoders that are required for the full playback of most of the most common multimedia files on the network. To successfully play them, you will have to resort to using a third-party player - for example, MX Player. True, it also needs to change the settings and manually install additional custom codecs, because now this player does not officially support the AC3 audio format.

¹ Audio in MX Video Player only played after installing an alternative custom audio codec; The regular player does not have such a setting.

Video output features tested Alexey Kudryavtsev.

Additionally, the MHL interface was tested. Apparently, only Sony still supports image transfer using wired connection(MHL 3.0 support is declared), since the number of devices that can display a picture via MHL or Mobility DisplayPort is rapidly decreasing. For MHL testing, we used a monitor ViewSonic VX2363Smhl, which supports direct MHL connection (in version 2.0) using a passive Micro-USB to HDMI adapter cable. At the same time, MHL output was carried out at a resolution of 1920 by 1080 pixels at a frequency of 60 fps. Regardless of the actual orientation of the smartphone, the display of images on the screens of the smartphone and monitor is carried out in landscape orientation with the connector on the smartphone to the right. At the same time, the image on the monitor fits exactly within the boundaries of the display area and repeats the image on the smartphone screen one to one. The exception is the start screen and, apparently, the windows of programs that, in principle, do not support landscape orientation. They are still displayed in portrait orientation, on the monitor - with wide black margins on the sides:

Sound is output via MHL (in this case, we used headphones connected to the monitor) and has good quality. At the same time, sounds are not output through the loudspeaker of the smartphone itself, and the volume is not adjusted by the buttons on the smartphone case, but is turned on / off. In our case, a smartphone with an MHL adapter connected, judging by the charge indicator, was charging.

Further, using a set of test files with an arrow and a rectangle moving one division per frame (see "Methodology for testing video playback and display devices. Version 1 (for mobile devices)"), we checked how the video is displayed on the screen of the smartphone itself. Screenshots with a shutter speed of 1 s helped determine the nature of the output frames of video files with various parameters: the resolution varied 1280 by 720 (720p), 1920 by 1080 (1080p) and 3840 by 2160 (4K) pixels and a frame rate of 24, 25, 30, 50 and 60 fps. In tests, we used the MX Player video player in Hardware mode. The results of this (block titled "Smartphone screen") and the following test are summarized in the table:

Note: If both columns Uniformity and Passes green ratings are set, this means that, most likely, when watching movies, artifacts caused by uneven alternation and dropping frames will either not be visible at all, or their number and visibility will not affect viewing comfort. Red marks indicate possible problems associated with the playback of the respective files.

According to the frame output criterion, the playback quality of video files on the screen of the smartphone itself is very good, since frames (or groups of frames) may output with a more or less uniform alternation of intervals and without frame drops. The brightness range displayed on the screen corresponds to the standard range of 16-235 - all gradations of shades are displayed in the shadows and in the highlights. When playing video files with a resolution of 1080p (1920 by 1080 pixels), the image of the video file itself is displayed exactly on the border of the screen in its original Full HD resolution.

With a monitor connected via MHL, when playing video, the monitor displays exact copy smartphone screen, i.e. the output is in true Full HD resolution in the case of 1080p files.

The range of brightness displayed on the monitor is the same as when displayed on the screen of the smartphone itself. The results of the monitor output tests are shown in the table above in the "MHL (monitor output)" section. The output quality is good, and even 60 fps files are output perfectly smoothly, without twitching. Recall that traditionally, to control playback from a smartphone, you can use the remote control from the TV (apparently, Sony).

The conclusion is typical: the MHL connection can be used for games, watching movies, web browsing and other activities that benefit from a larger screen size.

Battery life

The capacity of the built-in battery installed in the Sony Xperia X5 Premium is 3430 mAh. Even despite the high screen resolution and demanding platform, the device demonstrates a very decent time in all scenarios. battery life. As it turned out, not in all cases the smartphone uses a full 4K resolution, so the similarity of the results with the Huawei Nexus 6P with almost the same battery capacity is quite justified.

Continuous reading in the Moon + Reader program (with a standard, light theme, with auto scrolling) at a minimum comfortable brightness level (brightness was set to 100 cd / m²) lasted almost 16.5 hours until the battery was completely discharged. When continuously watching Youtube videos in high quality (720p) with the same brightness level through home network Wi-Fi device lasted almost 8 hours. In the 3D-games mode, the device worked for 4.5 hours.

The machine supports the function fast charging Qualcomm Quick Charge 2. The smartphone came to us for testing without a bundled charger, and with the help of a third-party charger with an output current of 2 A, the initial charge is carried out with a current of 5.1 V 1.5 A, but as you charge, these values ​​naturally decrease, and as a result, the battery of the smartphone is fully charged in about 3 hours.

Outcome

The Sony Xperia Z5 Premium is a rather peculiar mobile device, a kind of “exhibition” smartphone with top-end hardware stuffing “not for everyone”. Why, for example, should an ordinary consumer pay extra for a fourfold increase in the number of pixels on the screen, if he still cannot see the difference without a microscope? In addition, in reality, the screen does not always and not in all applications display an image in the same 4K resolution, and this resolution turned out to be not quite 4K. As for the rest, we are so used to the huge dimensions of such “handheld devices” that we don’t even pay attention to them, having completely untied the hands of manufacturers in this regard. True, even in comparison with most similar in terms of positioning Sony flagships Xperia Z5 Premium turns out to be one of the heaviest modern smartphones, the mass of which managed to cross the border at 180 grams.

Nevertheless, the hero of the review actually differs very little from the usual Sony flagships of the Xperia Z series. This is practically the same Xperia Z5, only with a slightly larger screen and, accordingly, dimensions. The sound system, hardware platform, set of communication modules, assembly, materials - everything here is the same or almost the same, and does not cause any special complaints. And the decent level of autonomy in the Xperia Z5 Premium frankly pleased us at all, of course, we expected a worse result. It is also very impressive that Sony, unlike most modern manufacturers, does not abandon the issue of waterproofing mobile devices and does not limit the possibility of simultaneously installing a memory card with SIM cards. For this alone, Sony is supposed to add points to karma.

With all this, Sony equipment, including mobile, has always been and remains one of the most expensive. To be honest, you can now find a lot of smartphones on the market at a price lower than the Xperia Z5 Premium, but with similar characteristics. Take at least the same Huawei Nexus 6P, the price of the 32-gigabyte version of which in Svyaznoy is already 9 thousand rubles lower than that of the Z5 Premium version of the same memory capacity. And yet, the Japanese brand still has enough fans, for sure there will be among them those who are ready to pay an amount of 59 thousand rubles for the model described today - that’s how much they are now asking for a certified Sony Xperia Z5 Premium in Russian retail.

In conclusion, we suggest watching our video review of the Sony Xperia Z5 Premium smartphone:

"Don't rock our boat!" - Sony engineers and designers send a harsh message to lovers of change with the release of the next flagship of the Z line. The Xperia Z5 smartphone - like Daniel Craig in the role of "007" - from film to film is strict, reliable, like a rock, invulnerable and therefore ... a little boring ...

Design and features

Each manufacturer that has been releasing a line of its own flagships under “numbered” names for several years is faced with a choice. You can treat the consumer with surprises, like Samsung - S5 was plastic, waterproof, with a replaceable battery and a slot for cards, and S6 became a glass sandwich, afraid of everything in the world, without the ability for the user to influence the memory and battery ... Truly a surprise ... You can, how Sony, take the second path - their flagships of the "Z" line demonstrate such a high level of design stability and consumer qualities that they manage to annoy even loyal fans with this. Sometimes the predecessor and successor are so similar inside and out that it is extremely difficult to understand the purpose of the generational change... One way or another, we have the Z5 in a dual-sim version - another bucket of oil on the souls of traditionalists who love the Z line precisely for its constancy in design and properties!

The Z5 evokes a sense of confidence and reliability with an aluminum frame engraved with "Xperia", topped and bottomed with scratch- and grease-resistant screen and back glass. The device is strong, monolithic, not subject to twisting, although it is afraid of falling on a corner or glass planes, like all its relatives.

The layout of the keys is traditional. Under the thumb of the right hand there is a power button (large, not an aluminum “pimple”, as before), muffledly clicking with a delicious sound with a pleasant tactile feedback. Beneath it are a volume rocker and a two-stage camera button. The left side is empty, on the top there is a headphone jack, on the bottom there is a charging socket (fortunately, not a newfangled type C!) and, attention ... a hole for a rope :) ! Lovers of tradition can rest easy - the Xperia Z5 is still the only flagship smartphone from the first-tier manufacturing community that still has the ability to be worn on a neck strap!

The cover of the only compartment hides slots for a memory card and two SIM cards. Both SIM cards are installed in one slot - on a common drawer.

And most importantly, the device is still waterproof, for which, in fact, many appreciate the flagships of the Z line!

Sony Xperia Z5 Dual:: Overview:: Display

I love the high brightness of the display, and when I turned on the Xperia Z5 for the first time and adjusted it to the maximum, I was unpleasantly surprised - has Sony really returned its smartphone line to two-year-old displays - dull and dull?! Ugh, hell - just in the usual place in the quick settings menu there is no check mark for activating the light sensor - it is only available in the settings menu in the "Display" section. The sensor was active by default, turning it off and turning the brightness control to the maximum, I was amazed again, this time pleasantly - I have not seen such a high screen brightness in gadgets for a long time! Direct sunlight significantly less impairs the readability of the Z5 display compared to many expensive smartphones, and by displaying a white picture on the screen (at least an empty window in the browser), you can make a very powerful flashlight from the Z5!

I remember that in 2012 I tested the LG Prada smartphone, which at that time was declared as the brightest in the world - its brightness was 800 nits (a nit is a unit of brightness equal to one candela per square meter). The Xperia Z5 has a claimed brightness of 700 nits, which is a very good indicator. And, of course, no one obliges the owner to use this resource to the fullest, burning the battery - the maximum brightness is only relevant outdoors on a sunny day.

Among other interesting things, the display has the ability to wake up with a double touch, enable increased sensitivity for operation with gloves, and adjust the color balance to your preferences.

Sony Xperia Z5 Dual:: Overview:: Fingerprint

Actually, this option has been present on a number of phones for more than a year, so it may seem strange to give it a separate chapter in the Z5 review. However, for Sony this is an innovation, before there was no such feature in any smartphone of the Xperia family ... However, if it were implemented like in Samsung, it was hardly worth paying such close attention to it, but the fingerprint scanner in the Z5 was made very unusual and interesting - in the thin SIDE release key, on which the finger rests comfortably and automatically.

The Samsung Galaxy and iPhone underscreen button, the LG V10 button, and the Google Nexus 5 ring sensor located on the back covers all require either not the most natural or frankly unnecessary movements. The button on the Z5 is much more logical - on it the finger turns out by itself, performing with one click both waking up the phone and unlocking it.

Sony Xperia Z5 Dual:: Overview:: Camera

The device has a camera module with a 1/2.3-inch matrix, 23 megapixel resolution, f/2.0. The camera has a so-called hybrid autofocus with a focusing speed of 0.03 s and SteadyShot stabilization - but this is not optical stabilization, but electronic.

The main camera menu control is a switch of 4 icons - the main modes, located along the right edge of the screen.

1 - Super Auto Mode (Basic, Intelligent Auto)
2- Camera applications (panorama, combination of images from the main and front cameras in one frame, 4K video, slow motion video, animation overlay AR effect, etc.)
3- Manual mode
4- Video shooting

The Z5's hybrid autofocus uses a combination of phase and contrast focusing principles. It is stated that the camera focuses in 0.03 seconds, but in practice it was not possible to feel a noticeable difference in focusing speed - everything is subjective, like in other flagships ...

At the maximum resolution (23 megapixels, 5520x4140 pixels), the camera takes a "square" frame in a 4x3 ratio. Therefore, all test shots were taken in a 16x9 widescreen version - the maximum available resolution for it is 20 MP. Actually, due to the fact that shooting with a “square” is unlikely to interest many, the number of megapixels, in fact, remained the same as the early predecessors of the Z line, which had 20.7 megapixel matrices.

I must say, the Z5 camera left an ambiguous impression. The main advantage of top-class smartphone cameras is the speed of focusing and burst shooting, according to which they have long overtaken camera cameras - “soap dishes” - I remember that the Xperia Z3 delighted me with the rapid autofocus speed, which allows you to cheerfully shoot moving people with virtually no blurring. That's just since the days of Z3, the quality of images of this kind has not actually improved. It is not bad, but even without complaints about the lack of optical stabilization, I would like to see at least some tangible progress ...

Photos of people in motion:

Night shots:

Against the world:

Close-up:

The device has a physical two-stage shutter button. Why it is not very clear ... As already mentioned, the speed of processing data from cameras in flagship smartphones in the last couple of years is so great that they no longer need to be pre-focused, as it was before - holding the on-screen button before shutter release or double tap a physical button… Let's say, the Galaxy S6хх line of devices shoots with excellent focus on one touch of the screen or pressing the volume button - why does the Z5 have an archaic double-action button ?! Actually, checking the button in practice showed that it does not give anything sensible ... Shooting in dynamics with it slows down - you can shoot moving objects only using the instant on-screen button or the volume button in shutter mode. The latter, by the way, is much more convenient in terms of holding the camera, if you are doing a “reporter's” shooting without advertising.

One way or another, but the main reproach to the Z5 camera is the lack of optical OIS stabilization. And this is a reproach from the category of regular - no longer to the first Z-flagship. Megapixels grow, their size decreases, susceptibility to smearing fluctuations increases ... Why does OIS stubbornly not appear in Xperia Z? Perhaps because on the example of competing camera phones, such as the Galaxy S6, Lumia 950, Huawei Nexus 6P and most others, it is clear that in order to introduce optical stabilization, the camera module has to be made thicker - either separately or at the same time thickening the body as a whole. In this case, the design of the THIN "sandwich" Xperia Z of two identical sheets of glass will undergo changes. This is likely to give engineers and designers headaches when it comes to waterproofing, which is why Sony can't decide...

Frame scaling examples from Sony Xperia Z5 and Samsung Galaxy S6. Due to the lack of OIS, a slight “soap” and an excess of contrast caused by the processing algorithm are clearly visible in the Z5 shots.

Sony Xperia Z5 Dual:: Overview:: Performance and Nutrition

The device is built on a powerful chipset Snapdragon 810 - MSM8994. This is a 64-bit 8-core (4 ARM Cortex-A57 2.0 GHz cores + 4 ARM Cortex-A53 1.5 GHz cores) processor with an Adreno 430 video core. The very “hot Qualcomm”. In benchmarks, he is not among the top ten, which, however, does not prevent him from having a decent performance in the highest degree - especially considering that many of those who are ahead of him often have the same hardware ... (Yes, you yourself understand - Chinese smartphone manufacturers are much closer and dearer in every sense to the most popular developer of the "parrot-meter" AnTuTu - Chinese, yeah ...)

The gadget is really very productive and powerful, but the thermal mode of the device requires a separate discussion. The device gets very hot - running something resource-intensive, you can wear it in severe frost in mittens, warming your hands! The Xperia Z5 successfully competes in this sense with the GK-1 catalytic gasoline heating pad popular with fishermen and tourists… Everything would be fine, but the warming up of the processor noticeably affects its performance. Here are the results of the popular benchmark, conducted three times in a row without pauses - for comparison, screenshots of the Samsung Galaxy S6, where the same three-time procedure reduces performance much less noticeably:

Let's conduct a simple and visual test, which I traditionally use to compare battery efficiency - charge the battery to 100%, reboot the device to clear the memory of clogging programs, turn off all wireless interfaces except for cellular communications, set the screen brightness and volume to maximum. We launch a movie in AVI format, lasting 1 hour 23 minutes and weighing 1.45 GB. After the movie ends, we look at the remaining battery charge.

77%. Not enough ... It’s enough for a day and a half, but this essentially means one day, since hardly anyone wants to look for an outlet for tomorrow by lunchtime.

Sony Xperia Z5 Dual:: Overview:: Conclusions

At the time of the review, the cost of the Z5 Dual was almost 45,000 rubles. The amount, I must say, is serious - especially against the background of the economic downturn. And you need to consider this amount, of course, not spherically in a vacuum, but in comparison, because the status of Sony's flagship has long ceased to provide the smartphone of the Z line with its own designation ... For example, for 40-42 thousand you can buy a two-SIM Samsung Galaxy S6 Duos - it will not have moisture protection, but it will have twice as much flash memory. For 38-40 thousand for fans of experiments, there is an option to try to get in the face of Meizu Pro 5 and the “best from everywhere” at all - a processor and AMOLED from the Galaxy S6, a 21-megapixel camera from the same Sony, as many as 4 gigs of RAM, 64 memory, and with it also has more anti-tactical "parrots" and a more capacious battery ... In general, it is obvious that the main strategic advantage of the Sony flagship is still the ability to swim, which no competitor's flagship can still do. This, of course, is a lot in itself, this is more than enough for regular fans of the brand, but is it not enough to attract new ones?..

very nice design and tactile sensations. there is a place for attaching a cord, where the phone can be hung around the neck. the battery charges fairly quickly.

Good camera, two sim card slots

Fast. Bright. Nice body. Gets Wi-Fi instantly. The call is loud. The speakers and microphone are of good quality. A good camera - both photos and videos. Video in 1080/60 format is generally gorgeous in quality - clear, juicy, no lags or sagging. It holds a charge for a long time if you use it only for talking.

A good camera, with good lighting in general, clear pictures are obtained.

I've been a Sony fan since the days of feature phones. However, this was last phone which I bought from this manufacturer. I never write any reviews, but this is really hot. The phone was bought in the fall of 2016 with the hope that it will last 3-5 years at least. At that time, it cost 37,000 rubles. And at that time everything suited, the shortcomings began to emerge later.

Big screen, 2 SIM cards, bright display

A month after the purchase, the corners began to fall off, after another 3 months it started rebooting by itself and in the middle the screen stopped working, and after another 3 months the screen began to peel off, the battery is not enough even for a third of a day. The phone is terrible

Almost immediately, the plastic corners of the frame flew off. the phone looks a bit messy. the battery drains quickly. upset that android version not the last. suddenly ("by itself") the rear window cracked

The case heats up, during active work / games it discharges very quickly

Heats up under any load. It heats up instantly - to the point that it hurts to hold it. Video in normal quality - you can’t shoot for more than five minutes - cuts off from overheating. The battery lands very quickly under any serious load. The power key is hidden flush in the body and is not as easy to find as the previous models. The connector for connecting the docking station has disappeared. Once a week it hangs tight.

It heats up during prolonged use on the Internet, the camera does not shoot very well in the dark.

I had to do a master reset several times already. There was a glitch that the speakerphone turned on by itself, there were still some glitches. Now for the points. 1. Often reboots itself. 2. A year later, some kind of stain appeared on the camera, which is why good photos you can forget. Everything is in a fog, everything is blurry. 3. The flashlight is very weak. So much so that it's almost useless. 4. Terribly buggy phone. Either one or the other bugs pop up. 5. Strongly heated. Sometimes for no apparent reason, and at such moments the battery is discharged right before our eyes. 6. The location of the buttons is not convenient. In particular, you constantly touch the camera key with your fingers during the photographing process itself, which causes the focus mode to turn on, and because of this it is unrealistic to take a photo. Do not use this button

Last year in Berlin at IFA, Sony Mobile Communications presented three models of the upper price range at the same time: in addition to the already familiar Sony Xperia Z5 and Sony Xperia Z5 Compact, they added the Sony Xperia Z5 Premium, the world's first smartphone with a 4K display. Additionally, both older models are available in versions with one or two SIM-cards.

V this review we will get acquainted with the dual-symbol version of the classic flagship - SonyXperiaZ5 Dual. Using his example, let's try to figure out what the new Japanese manufacturer can offer and how interesting its product is against the background of direct competitors. To begin with, let's take a closer look at the technical characteristics of the novelty:

Appearance, arrangement of elements

With the release of the fifth generation of Zetok, Sony has changed the design concept from OmniBalance to Sense Of Unity. Despite this, we have before us an elegant non-separable glass and metal bar, which is well known since the days of the Sony Xperia Z1. But there are changes, and they lie in the details. So, the Sony Xperia Z5 Dual has got a little more strict and straight outlines of the side faces, and thanks to a special treatment, the rear panel glass has become matte, which added practicality to the device. In addition, the smartphone has lost magnetic contacts for connecting the docking station, and the proprietary round power button has received an oblong shape and a built-in fingerprint sensor.

The usual color palette (black, white and gold) has been replenished with green, which effectively shimmers depending on the lighting conditions. In general, the device looks expensive and solid.

The dimensions and weight of the Sony Xperia Z5 Dual have not changed much, which allows you to manage it even with one hand. But we have some comments on the controls.

If in previous models the round protruding power button was easy to find by touch, the new one has practically no tactile highlight (slightly recessed) and is characterized by a sluggish short stroke. And the fingerprint scanner built into it does not work as well as we would like.

In particular, there are problems with fingerprint detection, even if most of the available slots are occupied by the same finger. Recognition occurs only when the finger is applied exactly at the angle at which it was scanned. With the right location, everything works quickly, otherwise you can use the PIN.

The position of the volume rocker also looks disputable - closer to the two-position camera button. According to the manufacturer, this is done for the convenience of zooming during shooting, but in practice you must have a fairly long index finger to reach it. During a call, the volume can be adjusted with the middle or ring finger (holding in the left hand) or thumb (holding in the right hand), but this increases the likelihood of dropping the smartphone.

The front side of the Sony Xperia Z5 Dual is covered protective glass. The frames around the screen are not the smallest: 16.25 mm on top, 15.5 mm on the bottom and 3.75 mm on the sides. There are a number of familiar elements: proximity and light sensors, company logo, front camera peephole, integrated notification sensor and stereo speakers. Onscreen keys.

The sides of the smartphone are covered with a metal frame with a matte finish. It protrudes slightly on both sides of the glass panels, which provides a more secure grip and non-slip on smooth surfaces, but digs unnecessarily into the palm.

On the left side there are slots for two Nano-SIMs and a microSD memory card (covered with a cap with a seal); on the right - the power button, volume rocker and camera key. On the bottom is a micro-USB port and a strap eyelet, while on the top is an additional microphone and a 3.5mm audio port.

On the back of the non-separable part of the Sony Xperia Z5 Dual is the main camera with a flash, an NFC contact pad, and the Sony logo.

Like previous models in the Sony Xperia Z line, the device is protected from dust and moisture according to Ingress Protection (IP) 65/68 standards. But now the manufacturer does not recommend completely immersing the smartphone in water and other liquids, and its improper or inappropriate use leads to the cancellation of the warranty.

The quality and rigidity of the body of the tested model are at a high level: all parts are perfectly fitted to each other, and nothing creaks or bulges during operation. Only during torsion, a slight compliance of the structure is felt, but this is not critical.

The Sony Xperia Z5 Dual has a proprietary 5.2-inch IPS-matrix screen with a resolution of 1920 x 1080 and a pixel density of 423 ppi. Yes, this is not a 4K display, but it is more than enough for any task. Phablet lovers can take a closer look at the Sony Xperia Z5 Premium model - here you have a 5.5-inch diagonal and a record-breaking 4K Ulta HD resolution.

The smartphone display leaves a positive impression. The screen is characterized by maximum viewing angles, a high level of contrast, bright and saturated colors, however, there is a noticeable deviation towards cold shades.

As before, there is the ability to adjust the white balance and primary color channels (RGB), as well as select ready-made image enhancement profiles.

The brightness adjustment range is sufficient for comfortable work on a sunny day or in complete darkness. Automation works quite adequately - without jerks and hitches. Multi-touch technology correctly handles up to 10 simultaneous touches. There is even a mode of operation with gloves. You can unlock your smartphone by double tapping on the screen. And when working with the camera, the sensor can be blocked.

Audio subsystem

As already mentioned, the Sony Xperia Z5 Dual smartphone is equipped with two multimedia speakers. They are located symmetrically on the front side (bottom and top). The speakers provide high-quality and at the same time loud sound: a wide frequency range is reproduced and even the presence of low frequencies is felt. At maximum volume, they do not wheeze, but high frequencies begin to predominate and the body resonates a little. In general, their capabilities are quite enough for games, watching videos, calls and notifications.

The package of the tested model does not include a headset, so the sound in the headphones was tested using gaming headphones (impedance 60 ohms) and in-ear Vivanco HS 200 WT (impedance 16 ohms). Traditionally for Sony flagships, the sound is very good, and the volume level is sufficient (there is a minimum headroom).

With minor manual adjustments, including when changing the equalizer, the sound becomes quite chic. For example, the ClearAudio+ feature adds clarity to the sound by boosting the highs but slightly dampening the mids.

Additionally, there is a radio module for recording and listening to FM radio stations with connected headphones.

Camera

The main camera received a proprietary Sony Exmor RS module (1 / 2.3 ") with a resolution of 23 MP and a fast lens Sony series G Lens with f/2.0 aperture. The focal length in 35 mm equivalent is 24 mm, which gives a fairly large viewing angle. Additionally, there is a hybrid focus system, digital image stabilization (SteadyShot) and LED flash. Video is recorded in 4K Ulta HD (30 FPS), 1080p (60 FPS) and 720p (120 FPS) formats.

In sufficient light, the camera focuses at lightning speed, but speed and accuracy decrease as ambient light decreases. The resulting frames are characterized by pleasant color reproduction, high detail and good sharpness, which suffers somewhat at the edges of the frame. In most cases, the quality of photo and video content is almost as good as direct competitors, but loses when shooting in artificial or low light conditions. When shooting 4K video, support for the H.265 codec appeared, that is, the quality remained the same, but the file takes up less space. The minimum focusing distance for macro photography is 8 cm.

The front camera has a 5-megapixel module, a lens with an aperture of f / 2.4 and a wide viewing angle. It copes with its direct duties quite well - the pictures are bright and detailed enough.

The main camera settings menu has changed markedly compared to what we saw in . It has become visually more pleasing and simpler, works faster, and finally learned how to remember the photo resolution set by the user during a quick launch through a hardware button on the sidewall. As before, many modes and effects are available, as well as a choice of manual or automatic shooting modes. True, in manual mode, photo resolution is limited to 8 megapixels, and only ISO, white balance and focus type can be changed from the settings.

Custominterface

The Sony Xperia Z5 Dual model runs on the still current Android 5.1.1 Lollipop operating system (update to 6.0 Marshmallow is expected), on top of which the proprietary Xperia UI shell with the Xperia Home 9.0 interface is installed. Visually, the shell has become even more simple and concise, in many ways reminiscent of stock Android.

As before, there is the ability to change themes, photos and the number of desktops. Menu « Quick settings» got the ability to display only the most necessary items.

The manufacturer removed all unnecessary and unpopular functionality, leaving the most necessary. Among the useful ones, one can single out pre-installed mini-applications ( fast access to a number of programs), applications (Sony Xperia Lounge, OfficeSuite, Lifelog, and so on) and services (What's New, Sony Xperia Store, TrackID, Spotify, and so on) for work and entertainment. Separately, it is worth mentioning the ability to record video from the screen built into the shell (turns on in the menu when you hold down the power button).

The smartphone settings menu is made in bright colors. There is access to almost all device parameters: communication capabilities, appearance, screen calibration, sound effects, etc. The usual power-saving modes (“STAMINA”) and gesture control capabilities remained in place.

In general, the OS not only looks good, but provides high functionality and just works great (without any hitches and slowdowns).

Performance and connectivity

Sony Xperia Z5 Dual received at its disposal the top-end 64-bit SoC processor Qualcomm Snapdragon 810 (MSM8994). It is based on a 20-nm process technology and includes four high-performance ARM Cortex-A57 cores with a frequency of up to 2 GHz and four energy-efficient ARM Cortex-A53 cores with a frequency of up to 1.5 GHz. Responsible for graphics Qualcomm Adreno 430 with support for OpenGL ES 3.1, OpenCL 1.2, Vulkan 1.0 and DirectX 11.2. The amount of RAM is 3 GB, and the permanent memory is 32 GB (21.5 GB is available to the user). You can expand this space with microSD memory cards (up to 200 GB). The hardware platform supports OTG mode, which will make it possible to connect an external USB drive, keyboard or mouse using the appropriate adapter.

The performance level is very high. This can be seen from both synthetic tests and real operating experience of the OS: any applications and demanding games work flawlessly, including at high graphics settings (for example, Asphalt 8: Airborne and WoT Blitz). However, almost any load, even not so long and high, begins to slowly reveal the back of the smartphone in the camera area. A high load, and this is primarily games and shooting video in 4K Ultra HD format, warms up the smartphone case to an uncomfortable state in 5-10 minutes. The temperature of the processor itself at the same time exceeds 60 ° C.

The built-in video player has just excellent support for modern audio and video formats, as evidenced by the results of the Antutu Video Tester benchmark.

The Sony Xperia Z5 Dual model supports modern 2G GSM, 3G HSPA+ and 4G LTE Cat.6 mobile networks. Support for two SIM-cards is implemented on the basis of one radio module. During the testing process, there were no complaints about its work. The speaker and microphone perform well. The vibrating alert is average in strength.

Communication modules are represented by dual-band Wi-Fi 802.11a/b/g/n/ac, Bluetooth 4.1, DLNA, NFC and Miracast. There is also support for the MHL 3.0 standard.

The wireless modules are working properly, demonstrating good speed and the necessary stability.

The global geopositioning navigation module supports GPS (A-GPS), GLONASS and Beidou satellite systems. Cold start takes about 5 seconds.

Offline work

The capacity of the non-replaceable lithium-ion battery is 2900 mAh. With a moderate load with 50% display brightness (calls, SMS, music, a little Internet), it will last for a day and a half of battery life. Using the STAMINA power saving modes, this figure can be increased up to 3 days.

As a result of watching HD video (MPEG-4 / AVC, MKV container, 4 Mbps stream), the device was discharged in almost 11 hours. A game simulation using Asphalt 8: Airborne ran out of battery power in 3 hours and 17 minutes.

The estimated battery life according to the PCMark benchmark was 7 hours and 12 minutes, according to the Geekbench 3 test - about 5 hours, while the GFXBench benchmark gave a result of 199 minutes. In all cases (except for the game), the display brightness was 50%, and the Wi-Fi and GPS modules were also activated.

The battery charging time from the power supply (5 V, 1 A) reaches 3.5 hours. The tested model also supports Qualcomm Quick Charge 2.0 fast charging technology.

Results

This year, Sony Mobile Communications presented a new line of smartphones at MWC - , which replaced the Sony Xperia Z. Therefore, SonyXperiaZ5 Dual can be safely called the swan song "Zetok" and one of best smartphones from Sony. Japanese engineers slowly but surely brought their brainchild to its logical conclusion. The case has not only retained the premium look and materials, but has also been completely matte, which adds to its practicality. In place protection against dust and moisture according to Ingress Protection (IP) 65/68 standards, albeit with some comments from the manufacturer. As before, we have an excellent 5.2-inch Full HD IPS display, high sound quality, good camera modules (5 and 23 MP) and the highest performance thanks to the top-end Qualcomm Snapdragon 810 and 3 GB of RAM. The device has support for all modern communications, which should meet the needs of the modern user. With each update, Xperia UX's proprietary shell is improved and offers excellent functionality and performance.

It's nice that the smartphone is devoid of critical flaws, but we still have some comments.
