Ive had my gs4 since it came out, and the battery life was never very good. I just thought it was normal. I have most features except data and wifi off, and while browsing the internet I can easily burn through 5% in 10 minutes. Right now, im down to 35% with 1.5 hrs of screen on time. This is mostly from internet browsing. Does this sound abnormal? I will post a picture of my battery usage in a second.
