Protect your device's battery lifespan with real-time charge thresholds, customizable warning alarms, gentle plug-in reminders, and live hardware charging metrics — all running entirely on your device.
One tap locks your alert threshold at 80%, then reminds you to plug in as the battery drops to 20%, 18%, 14% and 10%.
Monitor real-time battery temperature (°C) and live electrical current flow (mA) directly from your hardware.
Choose your preferred alarm tone, easily silence warnings, and auto-launch the app upon plugging into power.
Runs entirely on your device. Zero background data collection, zero tracking, and zero personal information gathered.
Drag the slider to preview how BatterychargeAlert notifies you in real time — no install required.
No. The app operates entirely offline and reads local battery hardware status only to power its own alerts and dashboard. Nothing ever leaves your device — see our Privacy Policy for full details.

You'll get a notification and your chosen alarm tone, with an optional full-screen overlay alert so you never miss the moment to unplug.
Yes, in Health mode. As your battery drops to 20%, 18%, 14% and 10%, a small card slides in at the top of your screen with a soft chime, each one a little more urgent. Each reminder shows once per charge, stays quiet when your phone is on silent, and plugging in resets them.
Yes. If your device reboots while connected to power, BatterychargeAlert automatically resumes monitoring.
Yes, the app is free to use. If you'd like to support development, an optional tip is available through Google Play Billing.
