That's a little higher than normal for me, for example, today I'm at 15 hours and have 14% left.
On days where I use my screen a lot I get less.
The other night I was working on some late night research and my phone was plugged in and I noticed the charging light turn green. Knowing I had at least 5 more hours to go before I was done, I un plugged it, put on Netflix over 4G, streaming some hd movie my kids watch, since Dr Seuss about trees. Anyway, i let it play at full brightness and recorded the time and percent. It died at right around 5.5 hours.
I ended up using the best fit line (linear approx) and wrote a model of battery life as a function of screen tine, brightness, and 4g vs wifi. I'll see if I am find it.
But over 5 hours is pretty respectable though. I was impressed.
