Do you have any inclination in terms of screen-on time? I have already confirmed that battery replacements (in support of my long-standing point) are largely irrelevant on iPhones, because they help a little when compared to degraded batteries if the iPhone is updated, but they do nothing to restore battery life of the original iOS version.
That said, degraded batteries cannot sustain the load - on iPhones - that new iOS versions impose, which is why my 6s on iOS 10 with 63% health has excellent battery life, but users with similar batteries on iOS 15 have widely reported extremely short runtimes and shutdowns (sometimes south of 1 hour of screen-on time), and that’s why battery replacements help a little (improving it to 3 hours, perhaps 4 with very light use, at most, but I’m getting twice that with a 63% health battery on iOS 10).
However, iPads have far larger batteries. Battery degradation isn’t as marked as on iPhones, especially when iOS versions weren’t as heavy, which is another argument in support of my long-standing point: grab an iPad 2 on iOS 9 and battery life remains half-decent even after 11 years, which makes sense: iOS 9 is a lot lighter than, say, iPadOS (any version). Newer iPads (starting with those who support iPadOS, like the Air 2), fare infinitely worse, with wide reports of a mere 4 to 5 hours of SOT on 1st Gen iPad Pros on iPadOS 16.
I’m inclined to think that battery replacements are even less helpful on iPads, especially considering that, like I said, extremely old iPads retain good battery life even after close to a decade of use, which would make sense: iPad batteries are several times larger, which would make battery health even more irrelevant.
So, a lot of backstory to ask a question: how’s screen on time on the new 10.5-inch iPad Pro?
