On the English-language YouTube channel PBKreviews, they published a large video showing the process of disassembling the flagship smartphone Xiaomi 12 Pro and showing its interior for the first time.
Now you can not only get an inside look at one of the first smartphones based on the Qualcomm Snapdragon 8 Gen 1 SoC, but also appreciate its maintainability. By the way, PBKreviews gave 6.5 points out of 10 possible for maintainability. This is quite consistent with most modern flagships.
Detaching the back panel and unscrewing 19 screws as well as the metal bracket gives you access to the motherboard. After disconnecting a few more cables, you can take a closer look at the main camera unit. The main Sony IMX766 image sensor with a resolution of 50 megapixels is equipped with an optical image stabilization system (OIS). The super wide-angle module and telephoto lens are devoid of OIS. Xiaomi 12 Pro received a multilayer motherboard with cameras on one side and a single chip system, RAM and flash memory located on the other side.
The key components are surrounded by a large amount of thermal paste and copper, which ensures quality cooling. The 4600mAh battery is fairly easy to replace. After removing it, you can see a rather large copper vapor chamber just below the battery and motherboard.
