Android offers many energy savings options, whilst they are helpful to gain more battery autonomy, they can easily target functions that are mandatory for a CGM system.
All settings described below will be available in your phone Android settings, appearance will greatly vary and depend on the phone vendor customizations.
Whenever going below a certain battery level, Android will shut down many services and prevent xDrip+ to function normally. Make sure you always keep a power bank with you to avoid this situation.
During normal phone use, make sure it is not enabled.
Apps battery savings⌁
Each phone app can be customized in terms of battery savings. Whenever experiencing issues, you should carefully review them. This also applies to OOP, WatchDrip+ (if used) and Bluetooth.
Android upgrades and updates
Updates and upgrades might reset these settings to default, always double-check afterwards.

Some Android phones don't show the Bluetooth app.
Bluetooth should run unrestricted if xDrip+ connects directly to a sensor.
