CNET Starts 4-Second Fold Test on iPhone Duo With Custom Durability Rig

Summary
CNET loaded Apple’s new iPhone Duo into its custom Fold-a-Phone machine on Friday to measure how many open-close cycles the foldable survives before its hinge or screens fail.
The rig runs one fold every 4 seconds—1 second each to open, stay open, close and stay closed—aiming to mimic normal use rather than stress the device at maximum speed.
Most foldables are rated for 200,000 to 500,000 folds, but Apple has not publicly stated a lifespan for the iPhone Duo, making the test an early benchmark for its first foldable phone.
CNET said the machine uses sensors, motor power monitoring, cameras, battery backup and 3D-printed phone mounts to track wear and stop safely if positioning fails.
Apple enters the foldable market about 7 years after Samsung’s first Galaxy Fold reached the US, a move CNET says could help push foldables further into the mainstream.
