Even if was a small % of the Apple lineup, the iPhone mini was one the best selling smartphones all brands considered.

This is the case for me precisely - I’ve been dismayed at the “phablet” sizing trend, and leapt at the opportunity to keep my iPhone reasonably-sized - I’m on my second SE now and I’m kind of dreading what will happen when I need to eventually replace it. 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.
