There are three main versions of Mi Band 4: Chinese with NFC, Chinese without NFC and global. There is also a specialized Chinese version without NFC Avengers Edition in the style of Marvel comics.

The NFC version has a contactless payment module and a microphone for communicating with the voice assistant, and has a reduced-capacity 125 mAh battery versus 135 mAh for the regular version. It is true that NFC only works in China, and you can communicate with the voice assistant only in Chinese.

In the global Multilanguage is available out of the box, and the Chinese version of the Russian menu appears after you connect to the Mi Fit and update the firmware.

Does Mi Band 4 support Always on Display mode??

Unfortunately, there is no such feature. This option may be added in future firmware. If you think the display is on too long, you can put a phalanx to the screen to forcibly turn it off.
