I’ve really been wanting to use my iPhone 13 mini without a case but the squared off edges on the design make it uncomfortable (for me).
I’ve tested a few different cases and settled on one that’s now stayed on my phone – the Apple leather case.

One of the great things about the Mini coming from a larger phone is that even with a case it’s still nice and compact. Now the leather case has worn in too it feels great.
The buttons are nice to use and the ports are easy to access for charging.
MagSafe works well for both my external battery pack and car mount.
I know it’s on the expensive side but I find it’s stopped me wasting money on other alternatives and will last longer.
Finally I found that the phone pops out of this case less than it did with the silicone version.
