While I understand your desire for a smaller iPhone (we all have different preferences), I don't think it will happen again. While it's easy to find people saying they want a small iPhone on an Apple fan website, even if they are a large number on the website, they are a minuscule portion of the non-techie people who are 99.999% of the consumer base for phone vendors.Still waiting for a genuinely miniature iPhone... smaller than the not updated "oh, it's not really mini" iPhone mini. Frankly, there's room in the line for a 5" mini (a small phone) and a 5.6" regular. Big iPhones are not for me. Us small phone lovers want one that disappears when we pocket the thing—a phone you don't want to spend your entire day staring into.

If they were the group that wanted a smaller iPhone, the iPhone mini would have sold well and we'd have an iPhone 14 mini right now. Also, there would be a flood of small low-cost Android phones on the market too. But there are not and that shows that the general consumer wants larger phones.
It needs to be financially worth it for Apple to appeal to a small group of aficionados, and after the failure of the iPhone mini, Apple knows it's not.
