On August 20, it was reported that Xiaomi's first offline camera model, MIX 4, had been officially launched in various channels recently, and the after-sales maintenance prices of relevant parts of the machine had also been announced on the official website.

It can be seen that the maintenance price of most parts of MIX 4 is less than 200 yuan, and the labor cost is 40 yuan. The main board, screen and back cover are relatively expensive.

The price of the replacement motherboard varies according to the memory/storage version: 2600 yuan for 8+256GB, 2800 yuan for 12+256GB, and 3200 yuan for 12+512GB; The out of warranty maintenance price of the screen assembly reached 1550 yuan. By contrast, the maintenance price of the Xiaomi 11 screen with the 2K E4 Samsung screen was 1430 yuan. It seems that although the display quality of the MIX 4 1080P China Star OLED screen is not top, the use of the camera technology under the screen may still keep the cost high; The maintenance price of its ceramic back cover is 680 yuan, much higher than that of other Xiaomi or Redmi models with glass back cover (generally 120 yuan or 130 yuan, and 420 yuan for Xiaomi 11 Ultra models with ceramic technology).

Anyway, for such a delicate and expensive mobile phone, it is still necessary to wear a mask and a case for daily use.
