Well title says it all, I've had this Nokia Lumia 920 for about 5 months now and am really enjoying the OS, problem is that the battery literally drains within 5 hours. Doing simple things such as texting and turning on the phone for 5-15 causes it to get very warm at the top right corner of the phone, and drain the at a high discharge. I've disabled almost every feature, disabled all but a few background task, and even replaced the battery this month but still the problems persist. Can anyone share any helpful info as to how to fix it or help improve my battery life?
