An Experimental Test Unlike Apple’s Own: iPhone Duo Hinge Durability
In an unconventional evaluation focusing on the folding mechanism’s longevity, Joanna Stern subjected her iPhone Duo to an intensive folding test, amassing over 32,000 folds over four nights. Despite Apple not disclosing official durability figures for the hinge like Samsung, Stern took matters into her own hands to assess the device’s resilience.

Stern noted that while she initially thought the hinge strength might be loosening, the actual test results suggested otherwise. A calibrated push-pull gauge confirmed the hinge was, in fact, stiffer post-test.
Everyday Use Reflects Minimal Change
Throughout the process, Stern reported barely noticing any difference in the hinge’s feel, emphasizing the device’s robustness. After enduring thousands of folds, the device maintained a condition comparable to its original state. However, she did not mention whether the crease created by folding became more pronounced, a common issue with other foldable devices.
Comparison with Samsung’s Official Testing
Samsung’s devices undergo official testing, with the Galaxy Z Fold7 passing a rigorous 500,000-fold durability test in 2025. This result implies significant longevity, offering users over ten years of daily use based on 100 folds per day, or more than six years for double that usage.
Apple hasn’t shared hinge tests on display and overall durability. Until then, Stern’s experiment provides valuable insight into their product’s endurance, though more unofficial tests are likely to emerge soon.
