OnePlus’s new aerospace finish faces the real-world durability test

The OnePlus 15 “Sand Storm” edition has drawn plenty of attention for its bold design and aerospace-grade durability claims. With a Micro-Arc Oxidation (MAO) coating said to be tougher than titanium and a fibreglass back panel, OnePlus promises that this version can handle everyday drops better than any of its previous models. But how does that hold up when the phone hits the ground?

Drop-test reports from early reviewers suggest that the OnePlus 15 holds its own impressively well in controlled conditions. When dropped from waist height onto a tiled surface, the phone’s frame showed no visible dents, and the fibreglass back panel only developed faint scuff marks. The MAO coating on the mid-frame, designed to resist abrasion and micro-cracking, appears to work effectively, preventing the kind of chipping or bending seen on older aluminium builds.

From shoulder height, which simulates a typical accidental fall from hand, the “Sand Storm” edition managed to keep its structural integrity intact. The corners took some impact marks, but the fibreglass back did not crack, and the frame remained rigid. Testers noted that the phone’s slightly rounded edges helped deflect shock energy, reducing direct stress on the display.

The biggest vulnerability remains the front display. Despite using reinforced Gorilla Glass Armor, the 6.78-inch LTPO panel cracked in some tests when dropped face-down onto concrete. However, the cracks were limited to the edges rather than the central display area, indicating that the glass’s impact resistance is above average for its class. With a screen protector or case, this risk drops significantly.

The OnePlus 15’s IP68 rating also adds to its durability credentials. It survived splashes, brief submersion, and dust exposure without damage. Combined with its rigid internal structure and fibreglass backing, it’s clear that the Sand Storm edition was built with rugged reliability in mind, even if it isn’t marketed as a fully “rugged” smartphone.

Weighing about 211 grams, the OnePlus 15 is heavier than most phones, which can increase impact force during drops. However, OnePlus’s internal shock absorption design — including layered graphite sheets and a strengthened sub-frame — helps dissipate that energy effectively. This likely contributes to its strong showing in drop and bend resistance.

Cosmetically, the Sand Storm finish performs better than glass-backed phones over time. The matte texture hides scratches, smudges, and dust remarkably well. Unlike glossy panels, it retains its clean appearance even after extended handling or minor abrasions. For many users, that durability in day-to-day use will matter more than surviving extreme falls.

Still, no amount of coating or engineering can fully protect a modern smartphone from repeated or high-impact drops. The frame may resist dents, but the glass will always be the weak point. Protective accessories like a bumper case or tempered glass screen protector remain essential if you want to maintain the phone’s pristine look.

For UK users, where cold weather and hard pavements make drops more punishing, the Sand Storm edition’s fibreglass back and MAO coating offer a tangible advantage. It’s less prone to shattering and surface damage than traditional glass phones, making it a strong option for those who prioritise long-term build quality.

In conclusion, the OnePlus 15 “Sand Storm” edition lives up to its durability claims. While not indestructible, it easily ranks among the toughest mainstream flagships of 2025. The aerospace-grade coating, fibreglass construction, and solid frame design ensure it can handle real-world drops far better than most competitors — giving users confidence that this stylish phone is built to last.
