I am big fan of iphone iphone 6 is very very very awosome phone Totally agree with you, I was on iOS 10 and it runs very good and stable but when I leave it with 20-25% battery and go to sleep in the morning its 0% and it off.

Everything work just fine phone perfomance is very very good.13 hours and using it a lot for work I am left with about 70 to 75%
Calling, emailing, social media, browsing. No issues at all with it.
