The Samsung Galaxy Z Flip 5 has defeated the Motorola Razr Plus by outlasting it in a human folding test. Here are the results.
In Youtuber's hand-folding test (live stream), the Razr Plus broke after 126,364 folds (hinge gave up after ~44k folds) while the Z Flip survived 273,316 folds (but lost ability to stay fully open after 223,000 folds) and is still going right now in the live stream.
EDIT: the Z Flip is now at 275,203277,350298,500 300k folds!
That is pretty intersting. If I had a fold I wonder how many times I'd open it daily. I would definitely flip it open and closed repeatedly throughout the day just to pass the time even when not intending to look at the screen.
Yep in a subsequent video he does address that, basically the 44k folds (ie the point at which the hinge broke) for the Razr Plus correspond to ~2 years if you assume that you open & close it 60 times a day, over a 1 year if it's 90~100 times a day.
His point in another video is that the machine is "too gentle" on the phone, ie it applies the pressure evenly on the phone, whereas that's not the case when we fold phones in real life. For instance, the Razr Plus was claimed by Motorola to withstand 400k folds, yet real-world testing shows that they give up after 44k cycles.
If you want your phone to last 5 years, at 223,000 folds (for full functionality including the hinge), that gives the ZFlip ~122 cycles per day, every day.
At 44,000 folds, the razr gives you ~24 cycles per day.
If you don't care about the hinge then that same 5 years gives you:
