I am using a 15 Plus. I know screen off is accurate in my case as I was listening to podcasts still using battery. I’ve seen people with 14 series and with the 15 PM show screen idle. Why would the 12, 13 series, and the 15, 15 Plus show screen off while the 14 series and 15 Pros show idle? Is there a setting that changes this? Just curious.
Starting with the 14 Pro series, they had always on displays so the only time they’re off is when they’re in a pocket or placed face down. Otherwise the screen will idle showing the time and whatever other lock screen widgets you have.
