I've been having battery issues the last few weeks. I go to bed with it fully charged, play a game for like 20 min and by morning it will be dead or dying. I found out that the Stock Gallery app is using 84% of my battery. I'm unable to Force Stop it. I'm using advanced task killer and it won't kill it. How do I resolve this problem. My phone is plugged in more than it's unplugged. I have Gingerbread/2.3.4
