Highlights
- iPhone Duo test revealed the screen crease after 10,000 continuous folds.
- iPhone Duo’s flexible display survived 1,000 folds at −20°C without pixel failure.
- iPhone Duo will be available globally from October 23, 2026.
Apple’s first foldable smartphone, the iPhone Duo, has already made its global debut, including India. As the phone is set to get into its fans’ hands from October 23, a viral iPhone Duo fold test review reveals its long-term durability concerns. iPhone Duo’s foldable display has been a major curiosity point for prospective customers.
YouTuber Folds iPhone Duo 10,000 times to See if it Breaks
A tech reviewer, Tim Pan, recently posted a video on X, showing whether iPhone Duo breaks after 10,000 folds. Pan did the 500 initial folds manually and 10,000 continuous machine-assisted folds at standard room temperature. He also tested 1,000 automated stress cycles inside a freezing environment.
iPhone Duo Fold Test Reveals Screen Crease After 10,000 Folds
The YouTuber wants to know whether the hinge holds up mechanically and observe how the flexible display ages over thousands of opening and closing cycles. The test amazed iPhone Duo’s fans, as the phone’s internal mechanisms are built like a tank, but there was a noticeable crease that appeared on the screen.
iPhone Duo Screen Crease Becomes More Visible After Repeated Folds
Apple’s iPhone Duo utilises a custom matte layer atop the flexible display, diffusing light reflection and minimising the seam’s visibility. However, after repeated folds and stress, the crease became more visible.
With initial 500 folds, the crease softened and slightly deepened, reflecting the look of the phone after a month or two of regular handling. With 10,000 folds, the phone’s display material developed a permanent, deeper line along the hinge that even Apple’s glare-reducing finish could no longer fully obscure when turned off.
How the iPhone Duo Hinge Held Up After 10,000 Folds
The video clearly shows the iPhone Duo’s internal mechanisms are performing seamlessly even after 10,000 continuous folds. Apple claims that the iPhone Duo is the most transformative change to the iPhone since the original. The phone’s hinge motion remained as smooth on 10,000 folds as it did on day one.
iPhone Duo Also Survives 1,000 Folds at −20°C
The iPhone Duo stress test also includes 1,000 folds at -20°C to see its temperature handling capability. Surprisingly, the inner display showed no sign of splintering, shattering, or dead pixel lines.
Before and After: How the iPhone Duo Display Changed
iPhone Duo showed up deep crease on display
The iPhone Duo features a flat inner screen, with a custom glare-reducing matte coating that renders the middle seam invisible under normal lighting. However, the image shows a deeper crease after 10,000+ continuous folds and 1,000 folds at -21°C.
The iPhone Duo fold test also revealed that the OLED panel retained the original full touch functionality with zero dead pixels, but the seam line became permanently visible.
iPhone Duo’s Peelable Screen Layer Revealed
Another video posted by Ice Universe reveals that when peeling off the iPhone Duo protective layer, uneven underlying bumps, ripples, and wrinkles are visible.
Does the iPhone Duo Fold Test Raise Long-Term Durability Concerns?
While the iPhone Duo fold test reveals the phone’s build quality and performance, many users raise concerns regarding its long-term durability. However, several users are also defending the iPhone Duo with its extreme mechanical stress test without breaking. One user on X commented that the YouTuber has folded the phone 10,000 times back-to-back, which creates heat, and no one is doing that in everyday use.
What the iPhone Duo Fold Test Does Not Prove
The iPhone Duo fold test shows continuous folds back-to-back that created a crease on the screen. However, it does not provide a complete picture to everyday users. Rapidly folding a device 10,000 times over hours skips the real-world impact of long-term environmental factors. It also does not match the standard human usages.
Nevertheless, it will be interesting to see how users feel once they hold up the iPhone Duo in hand.
