A South Korean YouTuber folds the Galaxy Z Fold 7 live over 200,000 times – and up to over 160,000 folds the smartphone essentially holds up, despite showing some minor damage.
The South Korean tech YouTuber tech·it (테킷) puts the Samsung Galaxy Z Fold 7 through an extreme durability test: In a livestream, he manually folds the device over 200,000 times. He wants to find out how much stress the new foldable can actually withstand – and how realistic Samsung’s promise of a ten-year lifespan really is.
According to TechRadar, Samsung itself states that the Fold 7 is designed for up to 500,000 folds. The YouTuber already achieves over 160,000 cycles in his test, with the first minor problems appearing on the second day of the test.
How does the smartphone perform under continuous stress? Throughout the test, minor incidents occasionally occur – but none of them result in a total failure. Here are the key milestones of the experiment so far:
- After 6,000 cycles: The device suddenly restarts by itself
- From about 46,000 folds: First cracking noises in the hinge
- At around 75,000 cycles: An unknown liquid leaks slightly from the folding mechanism
The livestream is currently ongoing with around 200 active viewers and stands at nearly 160,000 folding cycles (as of 08:00, 05.08.25).
What does Samsung promise regarding durability? As mentioned earlier, Samsung states that the Galaxy Z Fold 7 should withstand up to 500,000 folds. With everyday usage of about 50 folds per day, that corresponds to a lifespan of around 27 years. Independent laboratories like Bureau Veritas confirm this figure (via Bureau Veritas). For comparison: The Fold 6 was only rated for about 200,000 cycles (via TechRadar).
The live test by the tech YouTuber tech·it also shows that Samsung has made a real leap in terms of durability with the Galaxy Z Fold 7. The materials and the hinge appear significantly more robust according to the tester than in the previous model. And this is despite already visible problems occurring.
Nevertheless, the actual durability in daily life is subject to entirely different conditions. In everyday life, smartphones are not only subjected to constant opening and closing, but also to drops, heat, cold, or moisture. All these factors influence longevity – and are not realistically represented in the live test.
