Today when I had my iPhone 4S in my pocket, I felt it starting to overheat a bit. I thought nothing of it and just ignored it for an hour or two. About three hours later, it started to get pretty warm - like when playing a 3D intense game or something. I checked the battery level, and it had gone from 88% to 15%!! I had NOTHING running in the background, and it was simply on standby doing NOTHING (or so I think). Anybody else having/has had this problem? (P.S. I'm jailbroken on 5.0.1)
Well, this happened to me once.. I woke up once, touched my phone and it was burning hot, and was at 10% battery. When I checked SBS, it showed my memory to be at 15MB remaining (even after exiting stuff and rebooting. So I decided to find the cause. In my case it was a cydia related thing. Something had left uninstalled (no clue how), but I went through Cydia in Developer view, and cleaned up everything that I don't remember installing, taking care of the important stuff of course. That seemed to help out quite a bit. Now my memory is always at 275+ MB and it runs cool. Tedious task, but worked for me
It happened to a friend of mine who had left music playing with the volume turned way down (muted), and forgot to unmute after a phone call.
This had happened to my android and my older iphones . But all i did was shut them down for a while and recharge it and it was then good.
