Battery information is one thing that many iOS users like to know a lot about. Your battery is the one thing keeping your iOS device powered on and useful. If it dies, then your iOS device might as well be a paperweight until it gets charged up again.
While you can have a tiny little battery icon at the top right of your Status Bar with a complimentary battery percentage telling you what your current battery state is, it's not the most aesthetically pleasing way to see your battery information shown to you.
A new solution is BatteryStatusBar
by iOS developer John Rickman, which uses the entire width of the Status Bar to show you your battery level without taking up any space in your Status Bar. With it, you can lose the battery icon and the battery percentage completely with some other kind of Status Bar customization tweak, and a progress line will show you your battery percentage in real time instead. Shown above, BatteryStatusBar is out of the way of icons in the Status Bar.
BatteryStatusBar is fully customizable. You can configure the height of the bar, the colors of the bar, the position on the Status Bar, and easily enable or disable the tweak on demand from the tweak's preferences pane, which can be found in the Settings application:
By default, the tweak uses the following colors for the following battery percentages: >65% = Green, <65% and >30% = Orangish, <30% = Red.
Since the colors are fully customizable, you won't have to deal with these colors if you think they're too boring.
As your battery level goes down, the progress bar will begin to retract to the left side of the display. At full charge, the tweak will span from one edge of the display to the other.
The developer also plans to add additional features to the tweak, including Notification Center support, support for custom gradients, support for rotation, and support for Lock Screen and SpringBoard heights. At this point in time, the tweak works in applications, on the Home Screen, and on the Lock Screen.
If you would like to give BatteryStatusBar a try, it's available in Cydia's BigBoss repository for 99¢. It requires iOS 7 to be installed.
