I am using apple’s leather case and the magsafe wallet.

Leather case is solid. But if you use magsafe charger can see the marking on the leather in the long run.

A year plus.

The quality of the leather is really nice to hold and touch. However, if you are the person that change phone every year then it’s not worth it. My iphone 12 is going for the long run this time, which is why i decided to get the leather case

For the patina, maybe you can get the brown color or lighter colour leather to really see the patina. I got the dark blue leather case, the patina is bit hard to spot

I have to agree with you. But i dont see discoloration. Maybe you use alcohol to wipe the case?

That said, the side of my case turns black. Which i like. The case is blue all over and the side is a deep black like a line across
