That's it?? That's nothing.....I say stream HD YouTube for 20-30 mins and web surf for at least the same amount of time to really have a better idea on battery usage. But that's still surprisingly good.
There was some web surfing in there too, along with a couple hours of streaming music from sirius/xm. No streaming video though.
Right now at 1d 13h 10m my battery is at 67%. Granted not heavy use, but it is normal use for me. Obviously if you are streaming video you will drain faster. But still you will get much better life relative to other phones. I bet streaming video on that monster DNA screen will drain your battery in a hurry.
