For me it’s optimally 4 years Maybe 5 if the battery is fine (with 1 battery replacement around the 2.5 year mark).
But I’m also not a “power user” I just get the base one and I’m good for a few years. Even now I have the 13 base 128 GB and I’ve only used up around 50 GB (this includes 10GB iOS, 10 GB System data and 11 GB photos and that’s a full 2 year’s worth without enabling optimise photos). I’m guessing this is also why I don’t generally notice a lot of bugs.
