How to choose an iPhone case

Start with the model. Cases are cut per model — camera arrays and button positions move between generations, so an iPhone 15 case will not fit an iPhone 16. If you are unsure, check the model before you choose a case.

Then decide how sealed you need it. A drop proof case absorbs impact but leaves ports open. A waterproof case seals the phone completely, which is what you want around pools, boats, sites and beaches. The trade is bulk: sealed cases are thicker, and that is the honest cost of keeping water out.

Then how you carry it. Lanyard-compatible cases keep the phone attached to you when your hands are busy. MagSafe cases keep the magnet array working through the case for wallets, mounts and chargers.
