Hmm that still seems too good to be true. Can you do a test for me?No listening to anything really, mostly Safari usage (as in browsing and using sites/forums), with phone usage (mostly conference calls so the screen was even on for most of those), some TV streaming, and some other apps. To be fair, this was above average although for a fairly average day.

Screenshot your battery and then lock it and leave it overnight. (Don't plug it in) First thing when you wake up screenshot the battery stats again. I'd like to see how much the usage time went up when it was sleeping doing next to nothing.
I do this every once and awhile to see and usually overnight (about 8hrs) my usage will tick up 8-15 minutes over that time on my 7 running 10.3.3.
I'm just curious to see if maybe something is going on in the background more often when your phone is asleep in your pocket and racking up the usage times and you are thinking you are getting this illusion of ridiculously awesome battery life when actually you probably aren't and there is a process running racking up those minutes more often in iOS 11.
