iPhone Duo Passes 75,000 Folds in Our Durability Machine

The iPhone Duo has passed 75,000 folds on a custom fold-testing machine, a benchmark that puts its hinge and display durability under sustained, repeated stress. The milestone is the headline result of the latest round of testing, and it sets up the obvious next question: how does Apple's foldable hold up against Samsung's Galaxy Z Fold 8?

Fold-cycle testing is meant to simulate years of ordinary use in a short span. Each cycle opens and closes the device through its full range of motion, and the wear shows up in places like the hinge mechanism, the flexible display, and the seam where the two halves meet. A device that clears tens of thousands of cycles without a failure is showing the kind of mechanical consistency that matters once a foldable leaves the lab and goes into a pocket or bag every day.

The source material does not spell out a direct durability comparison with the Galaxy Z Fold 8, so the matchup remains an open question for now. Readers should watch for the head-to-head numbers before drawing a conclusion about which phone is more durable. Until then, the 75,000-fold result stands on its own as a notable data point for Apple's first foldable.
