Please refer to the following instructions to determine whether Bluetooth needs to remain on:
1. Pedometers, sleep & heart rate monitoring, stress/blood oxygen detection, and women's health can record data independently without a mobile phone. You need to connect to the mobile phone regularly to synchronize sports and health data. It is recommended to connect the mobile phone to record the track during exercise;
2. Functions such as stopwatch, alarm, calendar, etc. do not require Bluetooth to be turned on all the time.
Note:
1. In order to better use the band, it is recommended to keep the Mi Fitness APP running in the background. To avoid memory cleaning in the Android system and some security software cleaning processes or interception, please set it according to the requirements in the Mi Fitness APP >> [Device] >> [Notifications and calls] >> [Background permissions];
2. iOS phones cannot add background protection to applications. If an APP enters the background and is cleared, the system Bluetooth connection will not be disconnected. Message notifications can be used normally. Other data synchronization APPs (weather, sports health data synchronization, schedule, etc.) need to be reopened on the phone to use the Mi Fitness APP;
3. When iOS phones turn on power saving mode, the system Bluetooth connection stability will deteriorate and disconnection will occur.
