I have a Verizon Galaxy SIII, and while I love it, I've been getting some pretty bad battery life (< 2h screen time, ~8 hours total use). I noticed that Gallery kept ending up near the top of the list of things using battery. I only have about 4 pictures I've taken on this, and I did initially allow it to sync pictures with Google Images, but have since turned off any syncing of pictures. Nonetheless, Gallery keeps using up battery. Yesterday it used up 25% of the battery life, and kept the system awake for 9.5 hours. What can I do to stop this vampire?
