 Recent Android versions by default report *app usage* as a percentage in the Android battery settings screen.

+Confusingly, *app usage* is not the same as *battery usage* and is not even directly related to battery usage!
 The app usage (while in use) will be very high because FairEmail is using a foreground service which is considered as constant app usage by Android.
 However, this doesn't mean that FairEmail is constantly using battery power.
-The real battery usage can be seen by using the three dot overflow menu *Show full device usage*.
+The real battery usage can be seen by navigating to this screen:

 As a rule of thumb the battery usage should be below or in any case not be much higher than *Mobile network standby*.
 If this isn't the case, please let me know.
