With "BatteryIcon" you get a new icon on your home screen which gives you quick access to the 'Battery Usage' section in your Settings.app . To give you a nice feel of simplicity, we made a live icon just like your Clock.app . The battery glyph and color of the icon will update to the current state of your battery level and also the charging state of the device. In result, it will give you the ability to quickly glance at your battery level and charging status on your homescreen. You might ask, "Why do I need it if I can just look in the corner?" Well, our eyes are always on the homescreen, we open new apps very often. So why not have "BatteryIcon".
icon now displays whether the device is charging or not
