Ever since the last update, my phone battery has been draining very quickly. It was at 80% when I went to work this morning, I didn't touch it at all, and 3 hours later it was at 15%. It then quickly drained completely and shut off. I checked the battery usage and the main culprit was the stock email app, which was running in the background, as well as Google Play Services. I've changed the sync options for email, even though I never had any issues with this before the most recent update. Any help would be greatly appreciated.
