Hello guys! While I was on stock iOS 5.1.1 my battery lasted at least 10h and still showed 100% battery. After 11th or 12th hour it dropped down to 99%. Now since I jailbroke my phone, when I fully charge the battery it drops to 99% in 2 hours...there is not unwanted or phantom usage time which can be part of this.. So, which is the proper case between those two?
