ok...just saw this, went to post after taking a photo with the phone:
just hit the 20% message...currently 5h, 32min since full charge.
standby: 15 hours, 53 minutes.
charges all night. then on LTE & WiFi throughout the day. didn't watch too many videos, read mostly news/photo stuff. played WWF. I keep Location services on all times. BUT I keep my brightness at around 20-25% mainly because i think that is bright enough as is.
