How we test the best iPhone 15 case
Several of the cases on this list were previously available for the iPhone 14 models and we added them to the list based on our previous testing with the iPhone 14. Typically, we try to use the case on the phone for at least a day and make sure the buttons on the phone work properly with the case on. With some cases, we use them for several days or even weeks to see how they wear over time.
- Design: We evaluate the more superficial and cosmetic aspects of cases and consider how aesthetically pleasing they are, because people do buy cases solely for their colors and artwork.
- Durability: We look at how durable a case is, paying particular attention to corner and camera protection (raised corners on a case can help your phone survive face-down falls).
- Grip factor: We review the material the case is made of so we can talk about such factors as how grippy the phone feels in your hand and how protective the material is.
- Extra features: Some iPhone cases have extra features such as MagSafe, an integrated kickstand or grips, and, in the case of folio models, slots for storing credits cards and cash.
- Long-term testing: Though we don’t do long-term testing for most cases, we do use some of the most popular cases for longer periods to gauge how they wear over time and see how well our phone holds up during accidental drops with the case on it. That said, we don’t do formal drop tests.
- Waterproof cases: Only a few fully waterproof cases are available, but If the case is supposed to be fully waterproof, we test it by submerging it in water.
