On the other hand, I use some software on my modern sized iphone that's been scarcely updated since 2016 if at all. It was built for the SE form factor, but ios ui libraries can scale ios ui elements to the display size just fine. Developers just need to write performant code again like they don't have a modern iphone to work with. Performant code has benefits even when you have the latest iphone pro/max/whatever in your pocket, since it means the app will hardly be consuming battery life. Too many apps these days kill my battery life doing hardly anything at all, rendering some text and banner ads perhaps.
