Battery Alarm watches your battery and sounds an alarm at the levels you choose, so you unplug before an overnight charge sits at 100% for hours, or plug in before the phone dies in the middle of something.
About Battery Alarm
Set as many alarms as you need: one when the battery falls below a level, one when it rises above a level, or one when it leaves a range you want to keep it in. When an alarm goes off it can ring, speak the battery level out loud and vibrate, and each of those stops on its own after a time you choose.
The alarm behaves like an alarm clock's. It can take over the lock screen, it can be snoozed for a while or until the battery reaches a level, and it stops with one tap. During a call the alarm is lowered rather than silenced. Quiet hours keep the phone calm at night, while still letting through an alarm for a battery that is about to run out.
The main screen shows the battery's level, charging state, temperature, voltage and health, and how long until it is full. A 24-hour chart shows how the level has moved, with charging periods shaded. If something on the phone would stop an alarm from sounding, such as a blocked notification channel, a health screen explains what and how to fix it.
