Lately when my phone is dying, I try to plug it in at my computer and right away it goes from the battery charge to trying to boot. Once it gets to the lock screen it will instantly shut down and try the process again. Only way I can get it to actually boot again is to use a wall charger. This never happened before, anyone know whats going on? I have it jailbroken but very few tweaks are installed I guess i'm wondering why my phone doesn't charge (on the battery screen) for a while anymore like it used to, now it just boots instantly, did something turn this option off?
