I don't recall the actual amount, but I did do a Coconut battery test and the cycles were extremely high. My problem with it was, at least with the 9.7 iPad Pro, battery replacements weren't actually offered by Apple - they simply replaced the whole device. I'd be very curious if the newer designs (M1 especially) can actually have the battery replaced.I do apologize for being repetitive, but I can’t help but think about this possibility.
I’ve never something like that myself, and my experience with iPads and battery life is that it’s extremely stable even years after purchase. Like I’ve often said, I have a nearly 7-year-old 9.7-inch iPad Pro running iOS 12 (so, the same model). Battery life only dropped from 14 hours of screen-on time to about 10-11 after Apple forced it from iOS 9, almost 4 years ago. It never dropped again, and I can consistently get 10-11 hours of light use today.
Saying that iPadOS 16 is to blame would be nothing new (and the right answer here), but what I’m curious about is whether software alone could fix the issue. My experience with severely degraded batteries and original (or early enough) iOS versions is great. I have an iPhone 6s (similar processor to this iPad) on iOS 10 with the original battery and it works almost like-new.
I’m curious about this: would a downgrade to iOS 10 (if it were at all possible) fix the issue? For this iPad to get 45 minutes it must be severely degraded, even on iPadOS 16, no doubt about that, but would a downgrade “magically” resolve the issue? Honestly, I’d love to try.
Do you know what was its battery health (on Coconut battery) and cycle count before the replacement?
The days spent with Apple support entailed several clean wipes and re-installs, which did nothing to help. It was the battery.
