Xiaomi Mi Mix 4 teardown published, and there were some surprises

Yesterday Xiaomi officially unveiled its new flagship smartphone Mi Mix 4, and today its disassembly has already been published on the Web. There were some surprises: firstly, as it turned out, the power of wireless charging can reach 100 W (officially - 50 W), and secondly, during disassembly, there is a great risk of damaging the smartphone.

Mi Mix 4 is made in a ceramic case, but between the display and the case there is a thin "layer" in the form of a metal frame, on which the antennas are brought out - it is easy to damage it during disassembly. And you can't do without heating the case, but this is a standard procedure for most modern smartphones.

The Mi Mix 4 motherboard is made like a sandwich. In the upper part of the smartphone body, there is a single-chip system, main camera modules, UWB communication module, memory chips. In the middle, there is a wireless charging coil and an NFC adapter, a rechargeable battery consisting of two cells. In the lower part of the case, there is a loudspeaker, vibration motor, USB port (some of the components are located on the daughter board).  

LPDDR5 memory is recruited with Samsung chips, flash memory - with SK Hynix chips. Battery supplier - Dongguan New Energy, speakers, and microphones - AAC Technologies. If you look at the screen through the light, you can easily see the holes for light transmission to the camera sensor (round in the center) and light (rectangular). The third sub-screen sensor of the Mi Mix 4 is the fingerprint scanner. And another light sensor is located on the rear panel.
