Why does the Xiaomi Smart Band 9 drain fast and have short battery endurance?

A: Please troubleshoot as follows
1. The Mi Fitness APP is connected to the band, default settings, typical mode battery endurance is 18 days; AOD is turned on, the typical model battery endurance is 8 days;
2. It takes about 1 hour to charge the band, please confirm whether it is fully charged first;
3. After charging, update the band firmware to the latest version (1.1.xxx, the specific version number is to be determined) for use;
4. Check whether the sleep breathing quality monitoring function is turned on, the heart health monitoring mode is turned on (Heart rate is monitored in real time at this time), the high-precision sleep monitoring is turned on, the screen display is turned on, the screen is always on during exercise, there are frequent message reminders and screen on, all-day automatic stress detection is turned on, all-day blood oxygen detection is turned on or blood oxygen detection is used frequently, and the game dial is turned on to experience games frequently. The use of the above functions will cause the battery endurance of the band to shorten. You can turn it off and restart it and then use it to observe;
5. If the function that consumes power quickly is not turned on, you can restore the device to factory settings, reconnect it, and continue to use it for observation;
6. If the fast power consumption function is not enabled, and the problem of fast power consumption still occurs, submit the feedback in the APP.
Note:
It supports the Battery manager function. You can view the high-power consumption items that are currently turned on by the following paths: [Settings] >> [Battery manager] >> you can view the full-charge battery endurance that can be improved by turning them off.
