Ever since Apple started making their phones big I've wanted a smaller one. I never bought a mini because it has a worse camera and that's more important to me.
My wife actually has a 13 mini and loves it. I also wish that there were good smaller phones, but I can't really blame companies for focusing on what sells.
When companies try smaller phones, like the iPhone 13 mini, they don't seem to sell very well. So the companies stop making them.
