Went from the 7+ to the 12 mini

Much smaller phone but same approximate screen size.

I am 100% happy with my smaller phone, but it is worth pointing out that I almost never leave the house without an iPad or MacBook. So if I need to do something that would not be comfortable on the phone, and I am not walking or driving, I'll use the iPad.

Also, before switching to the mini, I noticed that more than 70 % of my interaction with my iPhone were done without using the scree. By that I mean I use the CarPlay screen, the Apple Watch or the headphone buttons, or I just talk to Siri. In none of those use-cases, the size or quality of the iPhone display are relevant.

Also, worth pointing that if I am not wearing my glasses, I could not read my mini, but having one or two extra inches of display would not make a difference. There might be people out there who have a hard time reading the mini, but their eyesight is just at the point where a plus or pro max is readable for them.
