Add a switch to that alarm screen to swap between sonar and accelerometer.
Sonar works best for when charging the phone overnight. (High battery usage)
The accelerometer’s low battery usage makes it the better choice when not charging the phone overnight.
Offten having to go deep into the menus to change back and forth.
