9to5Mac tested nine third-party cases for the iPhone Duo, ranging from $29 to $129, and landed on a single recommendation worth buying. The lineup includes Baseus, UAG, Aulumu, Smartish, Apple's own Folio with Kickstand, Dbrand, and Moft, covering wallet cases, clear grips, folios, and rugged builds across a 4x price spread.

The interesting material is not just the winner but the reasoning that eliminates the other eight. A $29 Baseus and an $89 Aulumu serving the same form factor tells you something about where the premium actually goes, and whether Apple's $129 first-party Folio justifies its position at the top of the bracket.

If you are buying a case for a phone that costs over $1,000, the full video breakdown of drop protection, grip, bulk, and wallet utility is worth 15 minutes of your time before spending anything.
