The arc length of a water droplet and the volume of the hinge are compared to that of the Xiaomi MIX Fold 3 hinge. Data is sourced from Xiaomi Lab, tested at a controlled room temperature of 25 degrees Celsius (±5 degrees) with humidity levels between 30%-70%, at a rate of 20 bends per minute over 500,000 folding cycles. Variations may occur due to differences in testing methods and environments. Actual wear may vary based on factors like usage duration and habits. The real-world experience should be considered the primary reference.

Three essential components: A structure entirely based on carbon.
Lightweight design
The Xiaomi MIX Fold 4 smartphones make extensive use of T800H carbon fiber, a material celebrated for its aerospace-grade quality. It is integrated into the keel hinge floating plate, screen support lining plate, and the middle frame battery compartment lining plate, covering an impressive area of 33,552 mm². This lightweight carbon fiber not only reduces weight but also enhances the strength of vital components, boasting an exceptional tensile strength of 5,500 MPa. Through a unidirectional tape process and five-layer precision molding, the impact resistance of the middle plate is increased by 300%.
*Impact resistance is enhanced by 300% compared to the aluminum alloy middle plate.* *This data is derived from test results conducted in Xiaomi's laboratory. Actual outcomes may vary slightly due to differing testing conditions.*
