The real reason the iPhone mini failed is not related to screen size, it's because its segment was canibalized by the cheaper alternative, the SE. The 2020 and 2022 sold like hot breads, wherehas their screen was almost an inch smaller than the iPhone mini. This is the proof that there a significant market for people who don't care about size and would gladly take the smallest option at a $100 discount from the regular one.
I just want something small that will fit comfortably in my pocket, and I can use with one hand.
I did this for years because I liked the form factor so much.
My new buying criteria for my iPhone is simply “buy the smallest one offered”.
But I’m willing to accept I’m not a big enough market segment to move the market.
Correct. To back this up a little bit with numbers, the iPhone 13 Mini all by itself sold about the half of the rate of the entire Google Pixel lineup. I bet lots of phone manufacturers would love to have half the sales of Google's premier Android phone. I also switched from Android to iPhone solely because of the 13 Mini form factor (I prefer Android, but I prefer a human-hand-sized phone even more).

The mini could have been simply, iPhone. The marketing would have been that they managed to add an extra .7" of screen, while reducing the overall size and weight. That's a great pitch. Who doesn't want a bigger screen in something that more easily fits in their pocket? Instead they called in a "mini", people thought it would be tiny and hard to use, so they didn't buy it.
The iPhone 12 mini screen was only .1" smaller than the screen on the iPhone 8 Plus... the giant option from just a few years earlier.
The mini was a marketing and brand strategy failure, plain and simple. It wasn't a small phone.
