Every day my battery life has gotten a little bit worse on my S3 since the JB update. It's horrible. I've been unplugged, mobile data off, Google Now off, GPS off and screen at 0% and screen time about 4 minutes and I'm down 9%. Before the update I could go 2 hours screen time, 2 hours talk time and 24+ hours total on a charge. Now I'm at 6 or so. I need help.
