The battery life on this phone is terrible. I have had it for a month and I have yet to make it 1 full day on a charge. I have tried everything; turning WIFI off when not in use, turning 3G off when not available; checking mail every hour or manually, turning location services off, turning all push notifications off. It still sucks. The second thing just happened a few minutes ago. I had the phone on vibrate. I picked it up to move it and realized someone was calling. I pressed the Home button but nothing would turn on. The screen stayed off but the phone was vibrating. What could be causing that???
