Why does the Xiaomi Smart Band 9 Active consume power quickly and have a short battery life?

If your band consumes power quickly, please check as follows:
1. If the Mi Fitness APP is connected to the band, with default settings, the typical battery life is 18 days;
2. It takes about 1 hour and 40 minutes to charge the band. Please make sure it is fully charged first;
3. After charging, update the band firmware to the latest version;
4. Check whether the sleep breathing score function is turned on, the all-day heart rate monitoring mode is turned on, the sleep advanced monitoring is turned on, frequent message reminders and screen lighting are turned on, or all-day blood oxygen detection is turned on or frequently used. The use of the above functions will cause the battery life of the band to shorten. You can turn them off, restart them, and then observe them;
5. If the function that consumes power quickly is not turned on, you can restore the device to factory settings, reconnect, and continue to use and observe;
6. If the battery consumption problem still occurs even though the function of fast power consumption is not enabled, please submit feedback in the Mi Fitness APP.
Note:
The Xiaomi Smart Band 9 Active supports the battery saver mode, which can extend the battery life after a full charge (laboratory verification data).
