Battery Charge Alarm

Battery Charge Alarm helps you know when to unplug, charge, or cool down your phone without installing a noisy optimizer.

Set a target charge level such as 80%, 85%, 90%, or 100%. Check device-reported battery level, charging state, temperature, voltage, plug type, current, and health status in a clean dashboard. Use low-battery and heat thresholds to stay aware during daily charging.

Core features:

- Full charge and target charge reminders

- Low battery and heat threshold settings

- Battery level, status, health, temperature, voltage, and current

- Local settings with no account required

- Light and dark themes

- English, Korean, Spanish, and Portuguese support

Battery Charge Alarm is a reminder and information tool. It does not repair, calibrate, boost, cool, or physically change your battery. Battery information is reported by Android and device hardware, so available metrics may vary by phone.
