I have a nice and fresh JB on 5.1.1 and this phone gets really warm, almost hot right by where the SIM card drawer is. The only tweak I currently have on this is SBSettings and it was doing that before I installed SBSettings. I had the same problem starting a month ago when I was JB on 5.0.1 and I just figured it was a bad Cydia tweak and I couldn't pin down the culprit but now that the phone has a fresh install of 5.1.1 and basically nothing installed from Cydia except for what comes with Cydia I'm confused as to what might be causing this. Battery drains really fast as well, nothing like the great battery life I was getting prior to having the hot phone issue last month. Any one else running into something like this? I wonder if I have a hardware issue...? TIA for any feedback.
