Today, it became known the Xiaomi Mi Band 4 passed the Bluetooth organization certification, and there are two models, including the XMSH08HM and XMSH07HM. Seems the former one belongs to the NFC variant, while the latter is the ordinary version. At the same time, the two bracelets also support the Bluetooth 5.0 protocol.
This means the data transmission rate will be improved, the power consumption will be reduced, and the network distance will be expanded. As for other functions, Cui Dawei did not reveal much, but he said that every generation of Xiaomi band will add some new health monitoring functions, and the fourth generation products are no exception.
