iPhone Duo Passes 160,000 Folds on Durability Rig

An iPhone Duo has passed 160,000 folds on a foldable testing machine, a stress test designed to repeat the opening and closing motion far more often than a person would use the phone. The headline frames the work as an open question: how far can the device go before the hinge or display gives out?

Folding endurance has become one of the most closely watched specs in the foldable category. Early devices built around flexible screens earned a reputation for visible creases, hinge wear and panel failures, and manufacturers have since reworked hinges and display materials in response. A machine count like this is a useful signal of how a design holds up under repetition, but it is a lab measurement rather than real-world use. It does not account for years of pocket carry, dust, temperature swings or accidental drops.

The report we worked from gives the fold count and the ongoing nature of the test, but it does not say whether the device still works at 160,000 folds, how visible the crease has become, or where the test will stop. Treat the figure as a progress update on a test that is still underway, not a final verdict on the phone's durability.
