Durability Tests of the iPhone Duo's Hinge

Apple has not provided specific data on the durability of the iPhone Duo's hinge, unlike Samsung, which typically offers a lifespan fold number. However, journalist Joanna Stern conducted a thorough test where she subjected her review unit to over 32,000 folds over four nights. Although she initially felt that the hinge might be loosening, she concluded that overall, she did not notice a significant change in its performance.

## Why it matters This test is important because it demonstrates the iPhone Duo's resilience under extreme conditions, which could be a deciding factor for consumers considering a foldable device. Durability is a common concern among users of foldable phones, and Stern's results suggest that the iPhone Duo could exceed these expectations.

## What we know Despite the 32,000 folds, the iPhone Duo's hinge remained as firm as it was on day one, which is a remarkable achievement for a device of this kind. A calibrated gauge was used to assess the stiffness of the hinge before and after the test, and the results surprisingly showed that it was stiffer after the test.

## What remains unclear It has not been commented whether the fold test affected the visibility of the crease that forms on the screens of foldable devices, a problem that has affected other models on the market. Additionally, the test was conducted with a case on, which could influence the results regarding the durability of the hinge.
