Used the phone quite heavily today setting it up just the way I like it. Screen brightness at about 80% on WiFi all day downloading all my apps and using Samsung Switch. Showed 9 hours 35 min. total usage with just under 7 hours, (6hr 43mn), screen on time with 13% remaining! While the total usage wasn't all that impressive, the on screen time was as good as I have ever gotten on any Smart Phone! Sorry that I don't have a screen shot of the total usage, but I do have one of the screen time if needed...now that it is setup and I can let the battery settle in, it will be interesting to see what kind of battery life this will get...my S4 regularly would ring up 17+ hr battery life with moderately heavy usage, lots of streaming/ podcast, screen on reading, and videos!
This is great but the really impressive part to me is the charge time! Tonight I timed the charge time from 7% remaining to 100% charge at exactly 93 min.! An hour and a half is amazing! Ironically, I won't be utilizing this since I will be going wireless charge as soon as the kit is available!
While this isn't battery related, my only disappointment so far with this phone is the BIG camera bump! Will have to do some research to make sure the case I put on this will protect the camera lens!!! I also had to invest a LOT of trial and error time into setting up the finger print scanner! Worked on this for quite a while but can report that it work every time now! It seems to increase in consistency the more you use it...like it is learning...so if you are having issues with this keep trying!
Cheers
