Perhaps one of the most concerning thoughts jailbreakers have after pwning their handsets is the amount of battery drain they’ll experience after installing a bevy of jailbreak tweaks. Understandable as this may be, it’s important to remember that many developers do everything in their power to mitigate battery drain. Still, this effort doesn’t eliminate it wholeheartedly.
If you’re any be interested in tracking the amount of battery drain that your jailbreak tweaks impose on your device, then we’d strongly recommend a free jailbreak app called Dra1n by iOS developers MegaDev and Charlie While. Not only can it give you a better idea of the amount of battery discharge your handset exhibits each day, but it can also outline the suspected battery-hungry tweaks installed on your device.
