New OnePlus phone: Tougher, deeper waterproofing
30 May
Summary
- OnePlus 15 adopts a thicker, chunkier design akin to Google and Samsung phones.
- The phone boasts IP66, IP68, IP69, and IP69K water and dust proofing standards.
- It features a unique micro-arc oxidation ceramic coating on its metal frame.

OnePlus has significantly altered its design philosophy with the introduction of the OnePlus 15. Moving away from its decade-long slim and curvy aesthetic, the new model adopts a thicker, more robust form factor that aligns it with devices from Google and Samsung. This shift results in a device that measures 6.35 by 3.02 by 0.32 inches and weighs 7.44 ounces, feeling dense despite its weight.
The phone's construction incorporates a unique micro-arc oxidation system, applying a ceramic coating to the metal frame. OnePlus describes this process as environmentally friendly and promises a frame stronger than aluminum or titanium, yielding a smooth, stone-like finish that offers a grippy yet slippery texture.
Durability is a major focus for the OnePlus 15, which meets IP66, IP68, IP69, and IP69K standards for dust and water resistance. This exceeds the common IP68 rating found on most flagships, allowing for submersion in up to two meters of fresh water for 30 minutes and protection against high-pressure water jets.
Externally, the OnePlus 15 features a squircle-shaped camera module, a departure from the brand's signature circular designs. The side buttons offer limited tactile feedback, and a single button on the left edge functions similarly to Apple's Action Button. The SIM tray, USB-C port, and speaker grilles are strategically placed on the bottom and top edges.
