I've had a Nexus 4 phone for about half a year now, and from the beginning, there's always been an overheating issue - not just a little warm to the touch, but uncomfortably-burning-in-my-pocket type of thing. It usually only happens when I leave it in enclosed spaces, such as a pocket or backpack, but there's no way I can keep my phone in my hand all the time! It keeps heating up, and the battery will go from 95%+ down to being dead within 2 hours. Has anyone else had the same experience and/or knows of any possible issues? Thanks!
