There are some improvements for sure. I went from 13 pro to 16 pro max which is a huge upgrade. - more processing power = smoother usage - a lot better cameras; more camera features too - pro to pro max battery is huge improvement - older phone’s battery isn’t the best anymore of course pro max difference might not be that big - brighter display - usb-c - camera button (imho it’s great even though people try to talk shit about it so much. It’s easy to use and very convenient way to use camera
