Battery life is STILL amazing. On day 2 and still have approximately a day & 18 hours left depending how much more usage I have while at work this afternoon.
Got a brand new one 2 weeks ago and straight out of box, before installing anything, I updated it to Nougat and the latest security patch.
Battery life is great.
Auto brightness at 30%
I charge it every day - usually at 35-40% to 96-100%
