Several days later and over 400,000 folds later, the Great Folding Test Vol. II is finally over. Youtube channel Mrkeybrd showed a multi-day live stream during which the Samsung Galaxy Z Flip5 collided with the Motorola Razr 40 Ultra (aka Razr+).
The Galaxy Z Flip5 was the last phone standing, after a whopping 401,156 folds. There were a few issues along the way, about halfway through (223,000 folds) the zipper lost its ability to hold corners half closed. However, the phone continued to huff up to the 400K mark.
The final count: Galaxy Z Flip5 dead after 401,156 folds, Razr 40 Ultra after only 126,367 folds
Samsung is officially advertising only 200,000 folds, verified using machines. The company puts things into perspective like this: 200,000 folds is 100 folds a day for 5 years. On purpose, Mrkeybrd he explains that performing the test by hand is more difficult over the phone since humans are not as accurate as robots, the robots neatly folding the phone with perfect alignment and even force.
For comparison, the Moto Razr 40 Ultra failed much earlier: it died at just 126,266 cycles. He started developing problems even earlier, after about 44K folds. This is despite Motorola claiming the Razr Hinge is rated for 400,000 folds, double what Samsung claims (but only the Samsung actually made it).
By the way, this same channel posted the following Razr failure video: Why they think it failed and how you can try to prevent the same thing from happening to your Razr 40 Ultra. And it also underscores the point that “humans break things faster.”
