Coming from 14PM, same as you, and for sure this was one of the big questions. Since a week back, after 2 iOS updates and initial set up processes etc, it has stabilised fairly good. Right now I have 14:38h screen active on roughly 50% of battery, would rate my self of being a medium/heavy user. Have Avg Screen active/idle of 8:43/2:33 stated for the moment, with a good amount battery margin in the evenings. Compared to the 14PM I don’t perceive that much of a downgrade tbh, had 87% battery health after 2y mind you. 16P is a very comfortable size…
