Apple’s First Foldable Phone, the iPhone Duo, Fails Extreme Durability Tests

Jakarta (ANTARA) – Apple’s first foldable phone, the iPhone Duo, reportedly failed a series of extreme durability tests conducted by technology reviewer Zack Nelson of the JerryRigEverything YouTube channel.

According to a report by Gizmochina on Saturday (24 October), the tests highlighted several weak points in the first-generation device, particularly its titanium hinge mechanism and inner flexible display.

In a test involving dirt and debris, the device was buried in sand, dust and soil. Grains of dirt entered the hinge through various gaps, preventing the phone from closing completely.

This happened despite Apple giving the iPhone Duo an IP68 rating for water and dust resistance. The device’s internal magnets were also unable to overcome the obstruction caused by sand trapped in the hinge.

The display damage began with the appearance of vertical green lines, which multiplied until the touchscreen stopped responding altogether. Replacing the inner flexible display is estimated to cost US$1,000, or around Rp15.7 million.

In scratch-resistance tests, the outer display, made with Ceramic Shield 2, proved highly resistant to scratches from sharp objects. The inner flexible display, which has a nano-texture coating, was considered reasonably effective at concealing visible scratches, but its surface remained vulnerable to sharp physical pressure.

Nelson said that most of the latest-generation foldable phones he had tested would usually withstand the series of tests, while the iPhone Duo showed the kind of vulnerabilities commonly found in first-generation foldable devices.
