I know people who put up with Android because they want a foldable phone, to be able to read documents more easily without carrying two devices. They're clearly not for everyone, but the relative sales of Pro vs Air or Mini suggest that these will be more popular than this suggests.
iPhone useful life is already pretty great. I'm using one regularly from 2020 (as a work device) - better than any laptop I've ever owned including classic-era Thinkpads have lasted as a daily driver.
