BatteryGuard: Battery Monitor

BatteryGuard helps you monitor your phone battery, charging behavior and temperature in a simple, clear way.

Keep an eye on battery level, temperature, voltage, charging status and power saving mode. The app records battery history in the background, shows clear charts and helps you react when your phone gets too hot or reaches your selected charging level.

BatteryGuard is designed for users who want better control over daily battery habits. It can remind you when the battery reaches a selected charge level, warn you about high temperature and show how battery parameters change over time.

The app also includes a battery care guide with practical tips on reducing heat, avoiding deep discharges and improving long-term battery habits.
