Right under 40° all day... with the screen off 90% of the time. Tonight I'm doing a test I've removed the back cover and its nowhere close to as hot as it was.before. I'm starting to think the battery cover is too close to the battery and internals thus causing overheating issues. I love this phone but I may try to swap it out for another while I still can. Has anyone else noticed similar issues? I'm underclocked at 800mhz screen brightness 10%. Does at&t charge a restocking fee if I return it?

well there must be a big current draw for it too get hot. android has a bug that shows up occasionally where the radio consumes large amounts of power. also 2.3.3 has a similar bug where the system wont sleep, this should only effect gingerbread but it may just be more frequent in gingerbread.
check battery usage in settings>about phone. if anything other than the display is over 50% there is a problem. if it is android system then shut it down and pull the battery for a few minutes, start it back up. if it is the cell radio then put it in airplane mode for a minute and take it out of airplane mode.
removing the cover may help it stay cool but there isnt enough heat there to cause battery drain, instead the cause of the battery drain must also be the source of the heat.
