What is your average battery temperature? When in use (surfing the web, etc.)? It seemed like the first few days my unit stayed pretty cool but now it is getting a little warm after only a few minutes use. It can get as cool as 28C when not in use, but has gotten over 40C with lite surfing/use. Normal? I have looked at all my apps and nothing seems to be running out of the ordinary. The only thing I am not sure of is in the app "spare parts" under network usage I have a top bar that says "0" and it is full. When I try to click on it for more info it force closes. Does everyone have this (is it normal) or is it something I need to check into further? Anyone know?
