I remain an irreductible fan of the one-hand theory, and therefore stick with an iPhone 13 mini. I might be late at the folding-phone revolution. Alas it seems we won't see any such phone that fits in a pant's pocket and that can be operated single-handedly. I am afraid that the 13 mini is the last of its kind. Yet many reports of people dropping their gigantic phones. Maybe that's a business model after all.
I broke my 12 Mini, replaced it with a 17, then went so far as to return the 17 and buy a used 13 Mini. It was totally annoying to me to not be able to operate the phone with one hand without feeling like I was about to drop it. I kept the 17 for most of the return window thinking I’d get used to it, but I just kept finding more situations where it bothered me. Battery life on the mini is not amazing, but a slim mags…
Edit: as others have pointed out it’s extremely hard to go back to the lightning connector too.
