Compatible with iOS 6 and 7
Percentage displays the iOS battery percentage only when the battery is under 20%.
The status bar looks great when it's clean, and you really don't need to know when you have 100% battery on your device.
Memory Usage: This tweak has been developed with memory and battery usage in mind. It uses only 0,1 memory every 5% battery change (that's nothing!), and will not effect your battery life.
