My smart phone history (dates are approximate):"Why the yearly cycle for flagship phones?" is a good question, given that the model seems to falter a bit:
- Apple iPhone 14 is a mere repainting of iPhone 13, with same chipset. iPhone 15 also seems to be a low iteration.
- Samsung S23(+) is just a chipset replacement of S22(+), plus little bells & whistles. Same for iPhone 15.
With S years, Apple more or less acknowledged a development cycle of 2/3 years. So far, they make most profit by issuing yearly phones, but this might be a defensive move:
a) if they wait for too long, they look outpaced, esp. since they're trailing in innovation (OLED, USB-C, Flip/Fold...).
b) Sadly, the only way to upgrade an iPhone is to buy a new one (same for Android flagships).
Nowadays, they're more "polishing edge" than "cutting edge", with ease of use, build quality, brand ecosystem increasing average revenue per user, etc. Would be happier with longer cycles though, this industry has gone a bit "waste while you can" imho.

2020 iPhone 12 Pro
(I've temporarily used various work phones over that period so had a good idea what else was going on. But always split my personal and work life.)
Which rather suggests the earliest model I'd update to would be the 16, and quite likely not until the 17. I feel like the rubbish being collected up by the dustcart after the parade. Aside from battery issues, falling out of full support (i.e. not being able to update to latest IOS) might be the biggest kick for me to update. (My 6s was tight on storage but that was because I got it very cheaply! The 128 I've got now is still plenty for me.)
