It’s possible that Samsung’s upcoming flip phone, the Galaxy Z Fold5, will use the new Waterdrop hinge being unveiled by Samsung Display at CES 2023. reported The Verge resource linking to The Elec and 9to5Google publications. According to sources, Samsung has started testing the reliability of the new hinge, where the creases at the crease of the screen are not that noticeable.

Samsung reportedly plans to test the mechanism to withstand up to 300,000 flexes, although the main benchmark is the 200,000 flex limit of the previous hinge design. This is significantly less than the Honor Magic Vs and Oppo Find N2 competitors, which are rated for 400,000 folds.
After 200,000 folding tests lasting four to five days, the hinge must retain at least 85% of its original strength. This test is theoretically equivalent to about five years of use of a foldable smartphone if the owner opens it a little more than 100 times a day.
On the one hand, Magic Vs and Find N2 foldable smartphones last about 10 years with the resource declared for them, which is an eternity by consumer electronics standards, The Verge noted. On the other hand, the Samsung Z Flip4 and Z Fold4 are IPX8 waterproof, which is not the case with Find N2 or Magic Vs. So if a user suddenly drops a foldable phone in a puddle after two years of ownership, they probably won’t care to know that the device could fold for another eight years.
