So I have a battery app installed for my phone from the market, "Battery Life" by Curvefish, to be exact. It tells me the temperature that my battery is currently running at. Sometimes me battery can run rather hot. Hot enough that I can feel it in my pocket. I haven't been using my phone for an extended period of time or anything, but I'm getting concerned. The hottest that it's ever gotten was 112 degrees. Do I need to be worried if it stays hot like that for a long time? How hot is too hot?
