When the battery dies.
Apple really needs to rethink the design to make it at least possible to have Apple replace the battery. I had to fight Apple for days last year to honor their stated "battery replacement" policy, when they finally got tired of me and gave me one of the last original 9.7 iPad Pros to replace my original 9.7 iPad Pro. The battery on it got to where it would die within about 45 minutes. You could sit and watch the numbers drop, second by second.
Despite that, they fought me on it saying the "battery health" still indicated it to be useable. The replacement unit eventually ended up with my mother-in-law who loves that thing (it's got a fast enough processor that it still runs great with the latest iPad OS). I did eventually end up with an M1 iPad Pro, which I also love and use daily.
But given the speed of the most recent devices, I can see them outlasting their batteries. A device as capable (and expensive) as these should not be disposable. Not ethical, from a business or environmental standpoint, imho.
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?
