Hello everyone, im new to the forums So i have this problem for the last couple of days. Yesterday i went to sleep and left my iphone on 52% locked. When i woke up it was on 35% even though i had wifi,3g,gps and everything turned off, and brightness to the minimum. I even set it to airplane mode and do not disturb. So i went to the settings and checked the usage, it said Usage 20 hrs 45 minutes, Standby 20 hrs 45 minutes. I am 100% sure i locked it, because same thing happened 2 days ago an i thought i didnt lock it. The phone is jailbroken, iOS 6.1.2 Anyone knows whats the problem?
