Battery Alarm & Charge Health Monitor

Never overcharge your phone again. Battery Alarm is a full charge alarm, low battery alert, and battery health monitor — all in one lightweight app.

We've all done it: plugged in, gotten distracted, and left the phone charging at 100% overnight. Over time that quietly wears down battery health. This app fixes it with one habit: a smart charge alarm that tells you exactly when to unplug.

SET YOUR OWN CHARGE ALARM
Choose 80%, 90%, or 100% as your charge limit and get a full battery alarm the moment you hit it. This one habit helps prevent overcharge damage and extends battery lifespan.

LOW BATTERY ALARM
Set a low battery warning at whatever percentage works for you — 15%, 20%, your call. Never get caught by a surprise shutdown again.

OVERHEAT ALARM FOR SAFER CHARGING
Heat is one of the biggest silent killers of battery health. This battery temperature alarm watches your phone while it charges and warns you the moment it runs hot, so you can unplug before damage happens.

CUSTOM ALARM SOUNDS
Pick your own ringtone and set volume separately for each alert: full charge, low battery, and overheat alarm.

BATTERY HEALTH MONITOR
Check battery percentage, temperature, voltage, and overall battery health status — all on one screen. A real battery health checker, no digging through hidden menus.

BATTERY WIDGETS FOR YOUR HOME SCREEN
- Battery Status Widget — charge percentage at a glance
- Battery Details Widget — temperature, health & voltage in one card
- Battery Saver Shortcut — jump into power saving mode
- Alarm Settings Shortcut — adjust alerts in one tap

QUICK BATTERY SAVER ACCESS
