> You change your phone every year? Because I have this Android phone sitting on my desk for development. When I bought it it was almost as responsive as iPhones (and much cheaper). 4 years later the UI is a lagfest [1].

As a counter anecdotal evidence: I bought my current Android phone before the pandemic started (that is, more than 4 years ago), use it daily, and it's as responsive now as it was when I first used it. While I don't have any iPhone experience to compare, I feel no lag when using it.
