I have taken screen shots of my battery use and screen on time over the past ten days. I have had the phone for a little over two weeks now, so the battery had been "broken in" before I started tracking battery life. During the day at work the phone is used lightly for things like checking facebook/twitter and is kept on 4g lte all day. Once I get home the phone is connected to wifi, and is used for more battery straining tasks like streaming hd youtube videos and games. Overall, I am happy with the battery results. The phone has gotten me through every work day without needing to be recharged. The battery will drain fast if you spend 15-30 minutes browsing the web or playing a graphics intensive game though. I tried to upload all 20 of the screenshots but the site would not let me upload that many files at once, so I put the results in the table below. The battery life number is from when the phone is unplugged in the morning to when it is plugged back in at night to charge.
