Just a few days ago I was getting really decent battery life. I would unplug it at 10am and by 11pm it was still at 40% with moderate use. Now I barely use my phone and it drops 15-20% in 20 minutes! Wtf?! I unplug it at 10am and by 11pm it is dead. I haven't really downloaded any apps, the only thing that changed is I uninstalled Advanced Task Killer because I read those are bad. Seems like my battery has gotten worse without it. Oh and my Cell Standby has been eating up 70% of my battery and the time without signal is almost always at 50% even though I'm in good signal areas most of the time. Can someone tell me what's going on with my phone and why it suddenly dies so fast?
