I am having an iPhone 5 64 GB.. I had jailbroken it on iOS 7.1.2 and then suddenly my phone stopped showing the accurate battery percentage.. It always stayed on just one number even after charging or using. Eg: it was stuck on 32%.. even when I charged for a whole hour, it showed same.. but when I did a respring, it showed the correct percent and then again got stuck on that number.. I thought it was some problem with the jailbreak, so I restored my phone with iOS 7.1.2 Now even after restoring, still my iPhone doesn't changes the battery percentage and it also has started to reboot automatically.. like it happened in PanGu jailbreak.. the screen dims and then the phone goes off and again switches on.. I don't know what to do!! Help needed ASAP..!!!
