My battery life is nothing like above. It is good though, can get me through a day and I charge every night.
During 8:30am-6pm through work my phone goes through about 30-40% (depending on usage). I have gmail and outlook email clients, my signal is strong through AT&T LTE and I rarely text during the day. Bluetooth on for streaming music in my car, wifi off, 30% slider with brightness and gps on high accuracy.
At night 6pm-11:30pm, this is when my actual usage goes up and I usually end the night out on average of 15% left. Best I had was 30% the other night.
My phone really shows battery drain when you actually use it, particularly with texting (using stock google messenger), i can see it drain.
