The Battery Power Widget displays the exact battery charge for your Android device. That is much more exact than the default power icon. The widget shows the actual battery charge as a percentage number and changes the background of the widget depending of the charging level. The background color changes from green to yellow to orange and red.

In short:

• Exact display of the battery charge in percent.
• Changing background of the widget depending on the charging level.

Try the app and have fun.
