About this app

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.

Ratings and reviews

Everything functions perfectly and is very visually satisfying, but there's just one thing that's keeping me from giving a 5 star rating: 'There is no Power/Wattage data'... My basic intuition tells me that this should in theory be easy, because the voltage is already actively measured, and 'I think' the current is also known 'or' it's actively measured as well. Depending on whether my current assumption is true, the Power should literally just be a little P=IV away. Please leave me a reply

Thanks for reaching out to me and fixing the UI issues now the UI is no longer behind the status bar and the translations on the home page looks good, there still some navigation issues (back gesture closing the app instead of going back) and the UI in general can get some work but these are nit-picks. Overall great idea and I'll continue using it

Love the app! please keep it ad free in the future 🙏! Bug noticed : charging time keeps incrementing after the battery hits 100% as long as the cable is plugged in, inflating the total time recorded.
