iPhone Duo Hinge Undergoes Extreme Folding Test
24 Oct
Summary
- A custom machine folds the iPhone Duo 900 times per hour.
- Testing aims to determine the foldable phone's hinge and screen durability.
- This test provides data complementing real-world reviews of foldable phones.

A specialized machine named Fold-a-Phone is currently subjecting Apple's iPhone Duo to an intense durability test. This proprietary rig is designed to fold the foldable device approximately 900 times per hour, meticulously monitoring the resilience of its hinge and dual screens.
The testing methodology aims to simulate realistic usage patterns rather than high-speed stress. Current foldable phones typically withstand between 200,000 to 500,000 folds. The Fold-a-Phone's continuous cycle will contribute valuable data to the understanding of foldable technology's lifespan.
Apple's entry into the foldable market, seven years after Samsung's first Galaxy Fold in September 2019, is seen as a significant moment. The iPhone Duo's existence is expected to legitimize the foldable phone landscape, previously viewed as niche. The test data will offer insights into the capabilities and potential limitations of this next-generation mobile device category.
