Keeping your phone plugged in at 100% for hours stresses the lithium-ion battery and reduces its lifespan. Charging to 80–90% and unplugging on time helps your battery stay healthy longer. Battery Alarm makes this effortless: plug in, walk away, and get a full charge alarm exactly when you want it. On the other side, a low battery reminder gives you time to find a charger before your phone shuts down. WHO IS IT FOR? • Anyone who charges overnight and wants a battery full alert • Gamers and streamers who need a charge alarm while playing • Travelers and commuters who rely on a low battery warning • Users who want to monitor battery temperature, voltage and battery health • People who want to extend battery lifespan and avoid overcharge PERMISSIONS Battery Alarm needs notification permission to ring alarms, and on some devices background/autostart permission so alarms fire when the screen is off. No location, contacts or internet-based data collection. Download Battery Alarm — the smart charging alarm and battery monitor that protects your battery and keeps you charged.
