When I first got the Ally in September my battery died really fast in a matter of 3-5 hours. The phone would get very warm while it died too. The problem went away for a few months, but today I had my phone fully charged and now in 3 hours it's gone from fully charged to 13% and the phone has gotten very warm. Any ideas on what to do? I've only sent two messages on skype and have been trying for the past 2 hours to download an avg antivirus app.
