Battery Alarm

Tired of permanently damaging your expensive phone battery by consistently overcharging or letting it drain completely? Battery Alarm is the essential, simple-to-use app that provides reliable, dual-mode protection to keep your battery in its optimal health zone (typically between 30% and 80%).

We use a highly reliable and efficient background monitoring service to check your battery status every 10 seconds, ensuring the alarms trigger exactly when you need them.

Maximum Charge Protection (High Limit Alarm)
Lithium-ion batteries suffer permanent degradation when constantly charged to 100%. Set your maximum desired charge limit (recommended 80%) using the 60% to 100% slider.

How it works: When your phone is plugged in and the battery level hits your custom limit, the app instantly triggers a distinct, looping alarm and a high-priority notification, prompting you to unplug your device and prevent overcharging damage.

Low Battery Alert (Minimum Limit Alarm)
Letting your battery drain consistently below 20% can also severely shorten its lifespan. Set your minimum charge threshold using the 10% to 50% slider.

How it works: When your phone is unplugged and the battery level drops below your custom limit, the app triggers a clear low battery alarm and a warning notification, reminding you to plug in immediately.
