Hello all, My Lumia 920 is currently running DP 8.1 (Update 1). The battery on my phone has been excellent, however every few days the phone tends to heat up and the battery seems to go really fast. I am assuming some sort of process or something is running in the background. This also occured with WP 8.0. I have tried many of the usual fixes like checking sync settings on email accounts, and making sure other apps are set to not run in the background, and also soft / hard resets. After I turn the phone off and back on its normal for a few more days and then I'll notice it heat up again and drain battery like crazy. Has anyone else seen this?
