Ensuring durability and protection for foldable smartphones

Honor aims to raise the bar for foldable resilience by targeting dual IP68 and IP69 ratings, reinforcing the hinge with Super Steel, and applying a low‑reflectivity coating. The upcoming Magic V6 must balance ruggedness with thin‑screen aesthetics while keeping weight manageable.

Technical Solution

The device integrates three core engineering layers: an airtight dust‑tight enclosure, a reinforced inner screen backed by ultra‑thin glass, and a hinge forged from the strongest commercial steel. Each layer is calibrated to meet both water and dust ingress standards without compromising flex.

Advanced Display Protection

Honor’s coating delivers a 1.5% reflection rate, achieved through low‑reflectivity nano‑layers and a reinforced UTG backing. This not only reduces glare but also adds wear resistance, a key factor for daily fold cycles.

Super Steel Hinge

The hinge leverages high‑tensile steel alloys that outperform typical aluminum or polymer pivots. Finite‑element analysis shows a stress‑distribution improvement of over 30% compared with prior generation hinges, supporting the IP69 dust‑tight claim.

Sealing and Rating Strategy

Dual‑seal gaskets surround the hinge and screen fold line, tested against ISO 20653 for water jet and dust ingress. The device passes the 6‑meter water immersion test and a 5‑minute high‑pressure water jet, qualifying it for IP68/69.
