I don't know if this is a Chevy thing or if it's something else, but as far as I know this has only been happening since I installed 4.71. For some reason, the screen keeps randomly turning on. The phone will be lying on my desk, and I'll notice the home keys just lit up, and the screen will be on. I can only imagine what is happening when the phone is in my holster - I'm wondering if this might be some of the cause of my recent battery woes? Anyone have any info on this?
