My battery has started draining at a ridiculous rate of about 1% every couple of minutes if I'm using the phone (just checking settings are light apps, no heavy gaming) or maybe 5-10% an hour when it's just in my pocket. I've tried a number of suggestions that are iOS specific, not jailbreak specific. I haven't added any new jb tweaks recently. THe last was anyvoice, about a month ago. I'm guessing the apple store will just swap my phone out for me, but in order to take it in there, I need to unjailbreak it, right? And then if they swap me, I'm stuck with 5.1, right? Currently unjailbreakable on my iPhone 4S. THoughts?
