According to Lei Jun, the cost of the CUP full-screen is equivalent to two flexible screens, namely a micro-bending AMOLED and a micro-drill arrangement of 400 PPI transparent screen seamlessly together.
Lei Jun said that the Xiaomi MIX 4’s CUP (Camera Under Panel) full-screen uses a self-developed pixel miniaturization technology, which is almost identical to the 3D flexible screen display in the rest of the phone and has an almost identical lifespan. The Innovative display technology: micro-drill arrangement, reset circuit layout, using transparent leads, to improve the screen translucency.
What’s more, Xiaomi Mi MIX 4 achieves 100% full pixel display with 400 PPI precision to present a perfect display effect. While ensuring excellent display, Xiaomi also hides a 20MP camera under the screen and adds an AI image enhancement algorithm to optimize the selfie effect.

In terms of display, MIX 4 with 6.67-inch AMOLED screen, resolution of 2400 × 1080, support for P3 color gamut, JNCD ≈ 0.34, dE ≈ 0.4, HDR10+, support for 120Hz refresh rate + 480Hz touch sampling rate, 10bit color depth, and True Tone true color display, dual front, and rear sensors, protected by Corning Gorilla Glass Victus.
In terms of core configuration, Xiaomi Mi MIX 4 was first equipped with Snapdragon 888 Plus processor, with a fully-optimized version of LPDDR5 memory + UFS 3.1 flash memory, cooling configuration for 3D graphene homogeneous temperature plate, battery capacity of 4500mAh.
Compared to Snapdragon 888, the main upgrade Cortex-X1 large core, its main frequency from 2.84GHz to 3GHz, while the AI engine by pulling up the frequency and software optimization to achieve a comprehensive performance improvement, arithmetic power 32 trillion operations per second (32 TOPS), AI performance increased by more than 20%.
In terms of imaging, the Xiaomi MIX 4 has a 108-megapixel main camera (HMX, 1/1.33-inch, OIS optical stabilization) + 13-megapixel free-form ultra-wide-angle (FOV 120°, 6P) + 8-megapixel periscopic telephoto lens (5X optical zoom, OIS optical stabilization) on the rear. The ultra-wide-angle is a free-form lens, which can produce almost distortion-free 120° photos without algorithmic cropping
The phone signal antenna has also an upgrade so that the metal small A shell as an antenna holder, support special network scenes adaptive mode, fixed-point network optimization, claimed to be the strongest signal quality Xiaomi phone.
Furthermore, Xiaomi Mix 4 anti-loss mechanism, claimed to be the phone that can not be lost, the official said that after the loss of the phone, with no shutdown, no network, no leaks, no theft, not compatible with other cell phone cards, which has a built-in virtual SIM card, even if the card can also be located.

- After the loss, continue to locate, even if the card is pulled out, it is useless,
- The mobile phone is deeply bound with the SIM card and wants to change the owner? No way,
- Don’t worry about private data, remotely clear it with one click.
The charging is still the main highlight of the machine, support for 120W wired fast charging, claimed 15 minutes to 100%, also provides a 120W thermostat second charge, 21 minutes to 100%, thermostat means to control the body temperature, built-in 10 temperature sensors, the official data 25℃ laboratory temperature, the whole shell temperature does not exceed 37 ℃.
Wireless charging is a big step forward, the default is 50W wireless second charge, the base noise is only 25dB, 45 minutes to 100%, but you can open the wireless speed second charge, which can be charged to 100% in 28 minutes.
In addition to the machine has Harman Kardon stereo speakers, X-axis linear motor, infrared, multi-functional NFC, UWB, balanced mode, sound noise reduction, system-level full-scene translation, and other features.
