Apple will not provide user replaceable batteries. That’s clear. It’s probably too expensive and complicated for them to do that and have waterproof devices. They instead offer replacements, and third-party shops know how to replace batteries too. With the airpods, Apple needs to be roasted endlessly for creating time-bomb trash though.
But staying realistic, Apple massively improved the repair ability with the iPhone 14 by sandwiching the phone instead of fitting it on the back plate. They also improved the repairability of their laptops recently.
The worst excesses of Apple’s poor internal design seems to be behind us.
