Hey There guys, I've been having this issue since one month now and it's driving me crazy and now am totally frustrated as i tried many fixes but nothing seems to work....... Here is the problem: I have a jailbroken iPhone 5 running IOS 6.0.1 and i started to notice just one month ago that the phone started to drain the battery very quick and get very hot, as a result making me able to use the phone just for 3 to 4 hours ?!?!? and charging the phone 4 times per day !!! Even if it was on standby, locked, 3G turned off and WIFI tuned off it drained 40% to 50% from the battery within 4 to 5 hours !!! I thought this could be a software issue so i uninstalled most of the tweaks that i got from cydia and installed an app to see if there was some applications or processes running in the background that kept on loading the processor and made the phone hot.... But the predecessor was idle all the time.... Just before i decided to get a new battery the phone run out of juice and it wouldn't charge or turn back on, even after leaving the charger connected for more than one hour !!! Installed a new OEM battery and first thing i noticed is that the phone turned itself on without holding the power button, i thought it was not a big deal and i continued to charge the phone to a full charge and started to use it but i had the same drainage and heat issue. Also what was weird is that when the phone run out of juice the screen kept on displaying that i need to connect to a charger just like if i was holding the power button while the phone doesn't have enough juice. And even if there were juice in the battery and i manually turned off the phone it kept turning back on !!!!!! But if it was connected to a charger and was running on and turned it off while still connected to the charger it kept it self off like a normal phone. I sent the phone to a repair shop and changed the dock connector and the power flex cable but still nothing........... Hope someone can help me with this issue. Thanks and sorry for the long write.
