The Battery Health application is designed to help users monitor and maintain the health of their device's battery. It reminds users to unplug their charger to prevent unnecessary wear on the battery and provides information on the amount of wear endured during each charging session. This can help users prolong the lifespan of their battery and maintain its maximum capacity.

The Battery Use feature of the app measures the actual battery usage of the device, taking into account information from the battery charge controller and which apps are in the foreground. This provides more accurate data than the pre-baked profiles used by Android, which can often be highly inaccurate. Users can monitor their device's battery usage, how long it can last in active or standby mode, and the power consumption of each app.

The Charge Speed feature allows users to find the fastest charger and USB cable for their device by measuring the charging current. This can help users optimize their charging time and ensure their device is charging efficiently. The app also provides information on how fast the device is charging with the screen on or off, as well as the estimated time remaining until the device is fully charged.

The app's highlights include the ability to measure the real battery capacity, track wear on the battery, and view discharge speed and battery consumption per app. Users can also see the remaining charge time and use time, as well as the percentage of deep sleep when the device is in standby mode. The app also offers a convenient ongoing notification for real-time battery statistics.

The Pro version of the app offers additional features such as dark and AMOLED black themes to save energy, access to historical sessions, detailed battery statistics in the notification, and an ad-free experience. The developers of the app prioritize quality and accuracy, and do not require access to privacy-sensitive information or make false claims.

The app also provides a tutorial and support for users who need help. The developers are a small, independent team with a passion for battery statistics and rely on support from users to continue improving the app. Overall, the Battery Health app is a useful tool for monitoring and maintaining the health of your device's battery.
