I still use my 12 mini; it's by far my favorite iphone I've had since my 5s. It might have had sucky battery life but I was just happy to have a phone that could fit in my pocket.
I've replaced the screen twice, battery once (by myself) and I have really very little intentions on moving to anything newer than the 13 mini.
I'm not sure why Apple doesn't care about the mini apple users. My friends, when they pull out a 17 pro look absolutely ridiculous, constantly having to pull the phone out when doing any real work since the phone just keeps getting in the way.
Count me in this group. I wound up buying the 13 mini right before it was going to be discontinued because I knew that would be the last small phone they would produce and I'm keeping it until it dies (or I can't get a battery for it).
