Xiaomi Mix Fold 3 to feature "Dragon Scale Fiber" back cover

Aug 05, 2023Aug 05, 2023

Xiaomi’s highly anticipated annual event, featuring Lei Jun’s speech and product launches, is scheduled for tonight at 7:00 PM Beijing time (11AM UTC). One of the most anticipated products of this event is the Mix Fold 3, which in the last-minute teaser shows it will have cutting-edge back cover material.

Foldable phones are more likely to be damaged after falling than straight-screen phones because of their mechanical structure. Xiaomi Mix Fold 3 has improved its reliability to address this issue.

Xiaomi’s teaser for the upcoming foldable suggests that the phone will be incredibly durable. The teaser highlights the phone’s “Xiaomi Dragon Scale Fiber” body material. Made from a blend of ceramic fiber and aramid fiber composite material, the fiber undergoes a high-temperature, high-pressure composite molding process at 150℃. The result is a body material that is incredibly strong and resilient, making it much more resistant to damage from falls.

The “Dragon Scale Fiber” used in the device is said to have advantages, including high toughness, high strength, impact resistance, and puncture resistance. In fact, a ceramic fiber thinner than a strand of hair can withstand a stretching force of 1.15 kg without snapping. This is 36 times more impact resistant than glass!

Because of these advantages, the dragon scale fiber version of the Mix Fold 3 is expected to be more expensive than the standard version. The price may be 200-500 yuan more, but it looks worth it for the added durability.

In other respects, the Xiaomi MIX Fold 3 will use the keel hinge. This hinge has an integrated non-porous design on the upper surface, which allows the keel to turn in the unfolded state. This will help control the crease depth on the screen.

Likewise, the inner screen of the foldable is made of ultra-thin flexible glass that is 2.25 times stronger than the industry’s common CPI plastic film. This ensures the flatness of the screen and helps to prevent it from cracking or breaking. The screen has also been tested to withstand 200,000 folds with only a 10-micron crease change.

The internal screen also uses a Pol-less Plus low-power large display that consumes 52% less power than traditional screens. Powering the Xiaomi Mix Fold 3 is a 4500mAh battery and a battery management system composed of three surging chips. The foldable phone is launching today alongside Xiaomi Pad 6 Max and the Redmi K60 Ultra, so stay tuned.
