A couple things I’ve noticed with my 13 mini over the last few days. First, the size is still perfect, I’m not finding it too small at all. I'll never know why I upgraded from my 12 mini a couple years back. I regretted the upgrade back then, and I find myself feeling a little uneasy just thinking about going back to my 14 Pro now. I pulled out my 14 Pro from storage just to play around with it again, I can’t believe how heavy and huge it is in comparison and that I've been using that for the last two and half years.
Second, the only problem I really ran into with it so far is my wireless CarPlay seems to stutter a bit more. Music and Podcasts still work fine, but I notice animations, Siri and reading messages seems to stutter and the phone over heats a bit in the car with or without charging. It's not a huge deal as things still work, just an observation. I just have to get used to using a device with half the memory, and less than stellar thermals.
I still have this week to use the mini before my return window is over. I already bought a case and screen protector for it, so I don’t really want to return it. I also figured I’d keep my old 14 Pro around as a backup.
Edit: Regretfully returning my 13 mini. I broke my foot a month ago, had a doctors appointment today for it and apparently it got a lot worse, so I’m pulled out of work for now. I'm not hurting for money, but that $400 could come in handy.
