I’ve been on an iPhone 12 Pro pretty much full time for the last two weeks. I switched back to my 13 Mini yesterday. A phone I’ve used for 10 months full time now feels like a new one. It’s amazing how quick you can adjust to different sized devices (I’m still convinced the 14 Pro is too too heavy though) but I almost dropped it whilst paying for groceries. It’s the width I misjudged and thanks to my Jedi like reactions I saved it.
I’ve gone back to using my favourite case (Peak Design Everyday) and my SIM is still in the Mini.
