Ah yes, the endless story. It doesn’t fail. Year after year. Update after update. It has been happening since I started to use iOS devices, 12 years ago. Not once does this fail to happen. It’s irreversible folks, downgrade to iOS 15 while you can and keep it there. There is nothing Apple will ever do to fix it.
Back with the massive battery runtime jump of the Xʀ, I had a little hope. I hoped this would finally stop happening. Very soon after iOS 13’s release, I realised it wouldn’t. Maybe, with a little hope, the M1 reverses it. Expecting the inevitable reports of ”my iPad Air 5 and 2021 iPad Pro’s battery life was reduced by at least a couple of hours with iPadOS 16, what can I do?”, however.
Not even the first major version is safe anymore. Unbelievable.
iPhone Xʀ on iOS 12, surpassing the vast majority of runtime numbers I’m seeing here, even with moderately heavy use (camera-centric). On that topic: users of the iPhone Xʀ repeatedly reported north of 10 hours of screen-on time with moderate use on iOS 12, the vast majority being closer to 12. Over and over: “11.5, 12, 12.5, 10 with heavier usage”, etc. iOS 16? “Be happy, 6.5 hours is a lot!“. I’m getting 6.5 hours of full LTE usage on an iPhone 6s on iOS 10, with… 65% health.
