I think there are going to be very different experiences depending on how you handle your phone. I had a black silicone case for years on my 12 Pro Max, and it was in fine condition at the end. A little worn, but no chips or tears. It mostly lived in my pocket with my wallet or sitting on a charger or flat surface. On the other hand, my wife was on her second silicone case for her 12 mini when we traded it in for a 15. Her case looked terrible and we probably would have replaced it if we weren’t about to get new phones. Her phone is often loose in her purse with other things including keys, so I’m sure it gets banged up and that’s takes a toll.
