For your reference, here are the setting methods below:
1. Power on/power off: The band will automatically power off when the battery level is low, supporting manual shutdown. When the battery level is low, the band will automatically power on when the battery level reaches the power-on state (about 3 minutes);
2. Reboot/reset: You can perform the operations by opening the [Settings] APP >> [System] >> [Reboot]/[Power off]/[Reset].
Note:
Data will be cleared when the Xiaomi Smart Band 8 is restored to its factory settings.
The cleared data types are as follows:
1. Daily data on the band such as heart rate, sleep, stress, blood oxygen, and daily activities (calories, steps, standing, moderate to high intensity), including historical data that has not been pulled by the APP;
2. Sport records on the band;
3. Cached weather data on the band;
4. The non-preset band displays pushed to the band;
5: The messages in the message list;
6. The added alarm clocks;
7. All settings are reset to the default.
