Why do we ever need a model called Max? iPhone 16 Pro will be big enough for everyone, while 16 Pro Max is unnecessarily large and unpocketable, which is against the notion of a mobile phone.
Imo, Apple should differentiate iPhone line as Pro, Mini Pro and Standard (cheaper to buy and targeting audience who don't focus on photography) starting from next year.
Mini Pro (or Pro Mini to name) should include almost everything that Pro have, but on a nicely scaled-down body. We had Mini, and it was designed quite professionally, yet still lacked most essential highlights like the 2x tele lens. New iPhone 17 Mini Pro may have the following camera setup:
48 mpx Ultra Wide
48 mpx Wide
48 mpx Telephoto (3x or 4x) allowing up to 30-40x digital zoom
Yes, it can be possible if you try hard! Does everyone need a bigger battery? No. A 25% smaller new-tech battery will be more than enough for one day usage. Does everyone need wireless charging? No. It can save some more space too.
