Is the battery removable for Samsung galaxy s7? Galaxy in danger: world's first analysis of Samsung Galaxy S7

If you don't like looking at microcircuits, then here is a short summary of everything that is described in detail below:

1. Galaxy S7 can be disassembled from the back, which means there is no risk of damaging the screen. Most service centers will undertake this type of work, and the repair speed will be higher.

2. The back cover is glued very tightly to the metal frame. There are no rubber gaskets under it, and the device is protected from moisture by the factory double-sided adhesive tape. If you leave your smartphone under the summer sun for a long time, the glue will gradually lose its properties due to severe overheating.

3. Button pusher turning on Samsung The Galaxy S7 seems more reliable than most other solutions. Which is great, because these buttons break often.

4. For the first time, Samsung installed a copper heat-conducting pipe inside a smartphone for cooling. The new Exynos 8890 chip is not only powerful, but also hot!

5. If the battery or other removable components fail and you decide to replace them in an unauthorized service center, then everything will go pretty quickly. But after this, the Galaxy S7 will most likely cease to be protected from water.

And now to the microcircuits!

How does it open?

The device opens from the back: you need to heat it and then carefully separate the back cover, which is attached to a special glue. There are no rubber gaskets here, water through back panel Double-sided adhesive tape does not allow penetration. At the factory it is pre-cut to the shape of the device.

If you leave the Galaxy S7 under the bright summer sun for a long time, the glue inside will gradually lose its protective properties. At some point, it may begin to let moisture inside the case.

There are no ugly plugs on the case, but pay attention to the tray for SIM and microSD cards. It is rubberized to keep moisture out. Before loading the tray and cards into the slot, be sure to check that no coarse dust has stuck to it. Otherwise, moisture may get inside the case.

S7 disassembled from the outside back cover, and not from the screen side. This is good because there is no risk of damaging the expensive screen, which can cost more than 20,000 rubles.

What's under the lid?

Unusually, the flash and sensors near it are not additionally protected; they can be seen through the glass on the back panel. This is not to say that this is bad, it’s just that Samsung closed them before. At the same time, by the way, we suggest looking at these sensors under a microscope. The black element with the inscription SWB-RC203 inside the case is a “sandwich” of an NFC module and an antenna connected together for wireless charging smartphone.

Second layer of entrails

We remove the top layer of boards and modules and go deeper. Here's a surprise: a copper heat-conducting tube for cooling. We've seen these more than once in reviews Sony smartphones, a similar cooling method is also used in the new Lumia 950, but Samsung is using such a solution for the first time.

Another interesting detail. See that little white square with the crosses? If water gets inside the case, it will immediately change color to red. This is exactly what the official experts will show Samsung services that the device was “drowned.”

By the way, do you remember that there are no plugs on the case at all, and all the connectors are open? The speaker is protected from moisture by a special mesh and a small rubber gasket.

At the same time, let's look at the battery: it really has 3000 mAh, although we, in general, had no doubts. The values of 4.4V and 3.85V have not changed compared to the batteries of the previous Galaxy S, but the temperature mark “do not heat above 45 degrees” is interesting. If the battery or other individual replaceable modules fail, they can be replaced quite quickly. After removing the back cover, of course, this will immediately deprive the device of the advantage of water protection.

Let's take a closer look at the details

Let's take a closer look at the speaker: there is a whole heap here, not very justified from a design point of view. For comparison, on the left is the speaker from the iPhone, and on the right - from the S7. This is not to say that this is bad, just a different approach. The headset cable comes separately and is docked to the charging cable. In previous models it is combined with a speaker module, so the solution is unusual.

We also examined the power button under a microscope. In the photo above - Galaxy button S7, bottom – iPhone button 5. In the case of the new Galaxy, the pusher is not simply glued to the base, as is most often the case, and implemented in the iPhone, but is additionally fixed on top.

Failure of the power button due to destruction of the pusher is a common disease modern smartphones. Samsung tried to make the design more reliable, which is commendable.

In the Galaxy S7, the contact groups are made removable. Obviously, with the aim of simplifying the work of employees of their own service centers. In general, the device has become easier to understand; a noticeable step forward compared to the S6 can be noted.

Let's look into the microscope again. Unlike Apple, which is used to branding literally everything inside, Samsung has almost no marks on its components. But we still found something. Here, for example, is the Samsung Shannon 935 LTE modem and the Avago AFEM-9030 power amplifier. Overall, Samsung continues to strive to use as many of its own components as possible.

Old base

In this frame, two boards lie side by side: to the left of the one from last year Samsung Galaxy S5 Active, on the right - from the brand new Galaxy S7. They are very similar.

Today we will talk about how to disassemble the Samsung Galaxy S7 and Galaxy S7 Edge. As practice has shown, this is quite possible to do even at home.

In principle, the first experiments on disassembling the Galaxy S7 were carried out almost immediately after the official presentation of the smartphone, in particular in Russia this was done by engineers from the Moscow Tech-Town service center on February 22. In general, specialists around the world have already managed to “dissect” the new Samsung flagship, and the manufacturer willingly provides copies of the device, usually with the condition of subsequent publication of the process.

We have already said above that disassembling the Samsung Galaxy S7 is possible at home. However, we do not recommend doing this if you have a valid warranty as it will void it. We also do not bear any responsibility for your manipulations in disassembling the Galaxy S7 and Galaxy S7 Edge.

According to experts, disassembling the Samsung Galaxy S7 is much easier than last year's Korean flagship Galaxy company S6, which many criticized for its design of low maintainability.

Disassembling Samsung Galaxy S7: procedure

Galaxy S7 disassembly begins with the back cover. Thus, there is virtually no risk of damaging the screen. Important point: like the Galaxy S6, the cover is fixed with a special adhesive tape, which is unlikely to be preserved. In principle, you can do without it, but in this case you lose IP68 protection against water and dust (another reason to have your new product repaired at an authorized service center). Experts also recommend carefully heating the back cover of the Samsung Galaxy S7 first (this is not dangerous, it is covered with durable protective glass).
The top layer of the boards is removed. This way you have access to the battery, which this time can be replaced without resorting to complete disassembly smartphone. If the purpose of disassembly was to replace the battery, we change it, and this will complete the process of disassembling the Galaxy S7.
Remove the remaining boards and gain access to the screen. This will not be as difficult as in the case of the Galaxy S6, since all contact groups are made removable.
Now you can separate the screen from the frame.

Galaxy S7 Edge teardown video

You can watch the disassembly of the seventh flagship of the Galaxy S line in the following video. Note that here the American version of the Samsung Galaxy S7 Edge based on the Qualcomm Snapdragon 820 processor is being “executed”, but the design is absolutely identical to the version sold in Europe and Russia in particular.

The first T-Mobile subscribers to pre-order the new flagship Galaxy smartphones S7 and Galaxy S7 edge have already started receiving their devices, although official sales will start only in a week. The specialists from Chipworks managed to get ahead of their colleagues from iFixit and do what they do best - disassemble the device.

Looking ahead, we note that the disassembly did not show anything supernatural. However, some features can still be highlighted.

According to Chipworks, the vaunted core Galaxy camera The S7 edge uses a 12-megapixel image sensor made by Sony (presumably an IMX260 model). The new photo module has a thickness of 5.4 mm, is equipped with a Dual Pixel phase autofocus system and is characterized by a photosensitive cell size of 1.4 microns. All this was discussed at a recent Galaxy presentations S7 and Galaxy S7 edge, so there are no new revelations regarding the camera. To help with image stabilization, Samsung chose the STMicroelectronics gyroscope (model number K2G2IS).

Oddly enough, the most interesting components of the Galaxy S7 edge are not hidden in secret compartments of the case, but are in the most visible place. The Snapdragon 820 single-chip system on which the smartphone is based is hidden under the chip random access memory Hynix 4 GB. As a controller touch screen Samsung's own solution is used – the S6SMC41X chip.

The microphone installed in the Galaxy S7 edge was manufactured by Knowles, the Wi-Fi module was supplied by Murata, the NFC controller was manufactured by NXP, the barometer was made by STMicroelectronics, and the wireless charging chip was made by IDT.

Usually the iFixit team is one of the first to reach new flagships of well-known companies. In the case of the Samsung Galaxy S7 (preview from MWC 2016), the palm went to our colleagues from Hi-tech.mail.ru. The publishing house's experts managed not only to get acquainted with the newly-made South Korean flagship, but also to look inside the device. If the surprises from the previous news weren't enough for you, what you found under the hood of the Galaxy S7 will also please you. Around Exynos processor 8890 and the Mali-T880 graphics accelerator you can see a small copper tube. Its task is to remove the heat that arises as a result of the operation of the chipset. Since the Galaxy S7 has a lot of features for gamers (Game Launcher application, Vulkan support API), such a solution will have a positive effect on the gaming experience on your smartphone, and will also protect it from overheating and damage. motherboard. It is noteworthy that previously there was nothing like this in Samsung flagships we have not seen.

In addition, experts noted more quantity glue and a firm fit of the back cover to the metal frame. In theory, this should protect the smartphone from moisture getting inside, but there is a possibility that excessive heating of the Galaxy S7 or repair of the device could negatively affect the water resistance of the flagship. Another advantage of the new product is the durable design of the power key, which can withstand the test of time with dignity.
