An ongoing durability livestream is putting a foldable device dubbed the iPhone Duo through an intense mechanical stress test. The automated setup has now pushed the folding hardware past the 260,000-fold milestone.

Continuous folding marathons have become a popular way for testers to gauge the endurance of hinges and flexible screens under extreme conditions. Surpassing a quarter of a million folds suggests a resilient mechanism, matching or exceeding typical multi-year usage expectations.

While interest around foldable form factors continues to grow, demonstrations like these provide an unfiltered look at how flexible displays hold up against repeated mechanical fatigue.
