The flip case of the Samsung Galaxy Z Flip5 has withstood over 400,000 opening and closing cycles

The authors of the Mrkeybrd YouTube channel subjected the Samsung Galaxy Z Flip5 folding smartphone to a series of difficult strength tests. Currently Live broadcastThe device lasted just under a week and was folded and unfolded 401,156 times while being subjected to real-world stress.

Initially, Samsung’s foldable smartphone was compared to the Motorola Razr Plus (this is the name the Razr 40 Ultra is sold under in the US), but the latter only survived 126,266 folding and unfolding cycles. The tests the creators have run on their phones are hardly scientific compared to the makers’ own lab tests, but that’s probably the whole point: they reflect the actual impact devices are being subjected to by humans, not robots. The bloggers also emphasized that neither Samsung nor Motorola had anything to do with their charisma.

The Samsung Galaxy Z Flip5 started failing long before it went dead: after about 230,000 cycles, the hinge broke and the device started opening on its own. At around 400,000 cycles, the smartphone has been subjected to extremely rigorous tests – immersion in water and in flour with eggs. The loop interference became more and more evident and the test had to be stopped when a pink line appeared on the right side of the screen. Previously, the Galaxy Z Flip5 was heated in parallel to open and close, put it under water and put it in a dust bag.

Officially, the device has protection according to the IPX8 standard, which means that it can work under water, but it is powerless against dust. The ability to withstand 400,000 cycles means the Samsung Galaxy Z Flip5 can be used for 10 years if folded and unfolded 100 times a day. For a Motorola smartphone, that means 3.5 years of normal operation. Last year, the Samsung Galaxy Z Flip3 survived 418,500 open and close cycles while being simultaneously submerged in water and subjected to dust and sand tests on the Mrkeybrd channel. And then, long before the end of the experiment, the hinge failed – the smartphone began to open by itself.
