iOS 15 would absolutely trash my battery overnight, until iOS 15.4 fixed it. Idle battery drain was like Y=-X all night long, with no app activity to show for it. This on an iPhone 13 Pro set up as new. That’s absolutely insane.
It would be great if just 1 person at Apple could be dedicated to constantly profiling the battery usage with the most common 100 or so apps installed and helping the OS team with battery optimization.
