I'm currently in the same position, upgrading from an iPhone 6s (2015) to an iPhone 16. The thing is, it is mostly not the apps which forced me to upgrade. I can't get newer ones, of course, but the old ones still work. (Except a supermarket app which practically deactivated its current app and asks me to update to a newer version which I can't install. There is no need, no new APIs except maybe developer convenience.) But the real villain is the web. Browsing simple websites becomes a chore, Safari becomes unresponsive for minutes at a time. Sometimes it feels worse web experience than the one an iPhone 1 with the checkerboard background. I blame React for having to pay money just to stand still.
