If you don't mind, could you take a screenshot of your screen-on time at the end of the day when you're about to go to bed? That kind of usage/battery life sounds amazing, by the way. No way my 5S could do all of that and even make it halfway through the day.
I'll try and remember, I get home at 9 and have an 19 month old waitin for me so I tend to forget about anything else at that time, maybe before I get into bed.
Currently here is where I'm at, not sure why it says 8 hours use, as I've had it unplugged since about 7am. I used it mostly to drive to work (80% screen, constant waze/gps for 2 hours, and 3 or 4 calls), and have only used it for 3 or 4 10 minute phone calls since I got to work. I'd estimate 2 hours screen/GPS time, and probably 1 1/2 to 2 hours talk time so far.
