Battery Supervisor

Battery Supervisor helps you better understand how your smartphone battery behaves.

It does not only show percentage, voltage, and temperature: it collects data over time and organizes it into charts, checks, and easy-to-read diagnostics.

With Battery Supervisor you can monitor:

• battery level, voltage, and temperature;
• charging and discharging trends;
• estimated app consumption, if you allow usage access;
• abnormal battery drain and screen-off consumption;
• possible charger or cable issues;
• charging sessions;
• voice alerts about battery status and detected conditions, when enabled;
• battery health estimation through the SOH Wizard.

The main feature is the battery diagnostic report: with one tap, you can get an organized overview that highlights what may have affected battery consumption the most, such as screen usage, Wi-Fi, mobile data, Bluetooth, GPS, foreground apps, temperature, and standby behavior.

The app also includes historical charts to observe battery behavior over time and identify unusual patterns.

Battery Supervisor is designed to be simple and practical: useful both for users who just want better battery control and for those who want to analyze consumption, charging sessions, and possible anomalies in more detail.

The analyses are estimates based on data available from the Android system and may vary depending on the device, Android version, and permissions granted. They do not replace professional measuring tools, but they help you better interpret everyday battery behavior.
