Product Overview

Xiaomi MIX 4 is the company's new flagship large-screen dual-SIM 5G smartphone available in limited geographic location. It is powered by Qualcomm's Snapdragon 888+ chipset as well as a three-camera setup with a 108MP main unit as well as multiple fast charging options, including 50W wireless fast charging.
A key feature of the MIX 4 is support for Xiaomi's all-new UWB point-to-connect feature introduced earlier this year. It makes controlling connected devices in a smart home via the smartphone a much smoother experience.
Compared to the Mi 11, which also features a 108MP camera, the MIX 4 switches out the macro camera for an 8MP periscope camera with 5x optical zoom. It is, however, inferior to the 48MP unit found in the Mi 11 Ultra.
The MIX 4's 6.67-inch OLED covers 100% of the DCI-P3 color space. It is driven at 120Hz with a touch sampling rate of 480Hz. An optical fingerprint sensor resides beneath it.

Sentiment Score 83%
Reviewers from notebookcheck have found the following***:
The Xiaomi Mix 4 can be recharged using the included 120-Watt charger. With a weight of 185 gram (~6.5 oz), it is almost as heavy as the smartphone. The 20-MP camera that is hidden under the display does a good job, but its quality is not quite as high as that of regular selfie cameras.
