Get Battery Display old version APK for Android
Keep informed about your battery status.
The Battery Display App shows basic battery information. With the notification service the battery charging level in percent can be viewed with one touch. There is a widget included to keep track on the charging state of the battery.
Notes:
This application does nothing very special ;-). So if you want more functionality, perhaps check out the other great battery apps.
If you use the Task Manager, you do not need the Battery Display App. All of its functions are included in the Task Manager.
