Only about 1 hour for screen time and music was only played like 30 minutes. This is my first full charge since I updated my phone to the latest with voice over LTE and that download booster.
Do you have GSAM installed to see if you can get a better idea of what is in use? After you reset, did you turn off WiFi always scanning in the advanced settings and disable any location and Google services that you do not use? Also see if removing your SD card makes a difference. If so, back it up and format it in the phone.
