Foldable iPhone Shows Visible Crease After 139,000 Folds

A durability test of a folding iPhone, referred to as the iPhone Duo, has reached 139,000 folds, and the result is a visible crease in the display. The only detail available is the headline, so it is unclear from that alone who ran the test, what method was used, or how the wear compares with a fresh unit.

The crease is the question that has followed every foldable phone since the first models reached buyers. A panel bends thousands of times over its life, and the fold line is where wear shows up first. A photo of the damage after a high fold count gives readers a concrete sense of how the hinge and screen hold up, even though it does not capture everything about everyday use.

Until a full write-up is available, the 139,000 figure is best read as a stress test result rather than a promise about how the device will age in someone's pocket. The details that matter most are how often the device was folded, whether the hinge stayed solid, and whether the crease affects touch response or display quality. Those answers will decide how much weight the result deserves.
