With Mix 4, Xiaomi has announced the first phone in the Mi Mix series in almost three years. Mix phones have always had a frameless design and seamless screens, and the Mix 4 continues this idea by commercializing the technology Xiaomi has been working on for a long time: a display selfie camera.

Xiaomi Mix 4 Features and Specifications

Xiaomi calls this technology CUP (panel under the camera), although it is similar to the on-screen selfie cameras we’ve seen from other companies. Like Oppo and ZTE’s recent efforts, the Mix 4 has a 400 ppi area on the screen that lets light through a selfie camera, which Xiaomi describes as “almost invisible”. The camera has 20 megapixels and a screen with a 6.67-inch 120 Hz and 1080p OLED panel.

According to Xiaomi, the CUP is “a technology copied by three great generations, five years, sixty patents, an investment of $77 million, and hundreds of engineers.” Last year, the company promised to start mass-producing smartphones with its third-generation screen-based camera technology from 2021 and is delivering on that promise with the Mix 4. Xiaomi first demonstrated its idea in 2019.

The Mix 4 is the first phone to be announced with Qualcomm’s new Snapdragon 888 Plus processor, an accelerated version of the flagship 888 chips with a peak speed of 3 GHz. (Honor has already said it will use 888 Plus in Magic 3, but this phone has not been fully d isclosed yet.) The processor is paired with 8GB or 12GB of RAM and 128, 256, or 512GB of storage.

The heart of the camera system is the 108-megapixel Samsung HMX sensor, which shows similar or identical performance to a slightly outdated but still quite good Mi 11. There is also a 13-megapixel ultra-high and an 8-megapixel 5x periscope. telephoto lens.

The Mix 4 has a 4500 mAh battery that can be charged with up to 120 W cord and 50 W cord. It’s not Xiaomi’s first 120W fast-charging phone, but it might be the fastest – Xiaomi claims the battery is fully charged in less than 15 minutes, compared to last year’s Mi 10 Ultra in 23 minutes. 50W wireless charging, on the other hand, takes 28 minutes to reach 100 percent.

Xiaomi has confirmed that Mix 4 has only been launched once in mainland China. Pre-orders start there tomorrow, general availability is August 16, and prices start at 4,999 Yuan (~$770) for the 8GB/128GB model and range up to 6,999 Yuan (~$970) for 12GB/512GB.
