Took the phone to the Cincinnati Reds game today (where we swept the Cubs thank you very much). Phone came off the charger at 10:30 after I parked. Used the phone while at the bar across from the park for random web surfing and texting until about 12:15 and then went to the park. Continued web surfing but also add in a bunch of photo and video taking, posting on Instagram and sending those to friends. At what was suppose to be first pitch at 1:40, a rain delay occurred that pushed game start to 2:50. In this 70 minutes I streamed Youtube TV watching NFL games. After the game started, proceeded to do some picture/video taking, messaging, and checking on the Mets game constantly. At about 5:45 I got back to the car and had 54% battery life.
This is about as hard as I'll push it and I was pleasantly surprised with the results. I'm not concerned about the battery at all from this point on.
