DISCLAIMER: The author is not responsible for usage of My Battery. By using this app you accept the fact you are responsible of all direct or indirect damages to your device/battery and to peoples/things.

My Battery does three simple things: it shows battery information, displays a notification status with battery level and acts as a fast discharger.

Last feature is accomplished by turning on screen, wifi, bluetooth, vibration and flashlight (if present) of your device and you can choose which ones to activate and how much frequently (wifi/bluetooth) modules scans for coupling, so you can accurately tune how slow/fast the discharge will be and which state modules are not altered during/after fast discharge.

Moreover, My Battery lets you decide safety levels of charge and temperature of your battery and stops fast discharge when those levels are reached. Fast discharge automatically stops too when your device is plugged. You can also configure My Battery to play a continuous sound (if the app is running or notification set to persistent) when level of charge goes under the minimum you setted: a secondary notification will be showed and sound will stop if you tap it.

Main features:

• Battery info: detailed information about device battery
• Notification: battery status in notification area
• Fast discharge: accelerate the discharge of your battery
• Power usage: standard Android power statistics
• Copy to clipboard: send battery information to clipboard
• Help: instructions about My Battery usage
