I have noticed my D3 soing this the last couple days. I have had my d3 for about 2 weeks now. Up until a few days ago, the phone was doing great. About 2 days ago my battery died after 3 hours. I just figured it was because I was in a new building where there is no cell service, figured it drained the battery trying to find cell service. But now everyday it starts getting really hot on the back by the processor and the battery keeps dying really quick. I have not changed any settings nor have I installed any new apps.
my wife has the same phone and hers doesn't get hot at all. I don't understand what is going on.
I have tried the advanced task killer since to see if that helps, but it doesn't.
when I am using the phone for talk or data, it never gets hot. It's only every now and then that it just gets really really hot then starts killing the battery.
