My phone is fixed! I'm not sure exactly how. The battery does not drain with the screen off anymore! Here's what happened: 1. Yesterday, my PIN to unlock my phone just suddenly stopped working. I have no clue how that happened. 2. I tried using Android Device Manager to reset the lock screen, but it didn't work because the lock screen was already set to PIN. 3. I thought I was hosed, but just in case, I rebooted my phone. 4. The PIN worked! HUH??? I then immediately turned off all authentication and I deleted all the certificates on the phone so that I could turn off authentication. Over 14 hours on battery and I'm over 50% battery life remaining with normal usage during the day (surfing the web, videos, texts, FB messenger, calls).
