Materials & Durability of the OnePlus 7 Series

The OnePlus 7 series represents a significant leap in smartphone design, combining premium materials with robust engineering to deliver a device that is both elegant and resilient. From the aluminum frame to the advanced glass protection, every element is crafted to enhance durability without sacrificing aesthetics. This guide explores the materials used across the OnePlus 7, 7 Pro, 7T, and 7T Pro models, and evaluates their real-world durability for everyday users.

Premium Materials Across the Series

Aluminum Frame & Glass Build

All models in the OnePlus 7 series feature a high-strength aluminum frame, providing a perfect balance between lightweight portability and structural rigidity. This metal frame acts as a protective skeleton, helping absorb impact during drops and resisting bending under pressure.

The front and back panels are constructed from Corning Gorilla Glass, with the OnePlus 7 and 7 Pro utilizing the latest Gorilla Glass 6 at the time of release. This glass is engineered to survive multiple drops from up to 1.6 meters onto rough surfaces, significantly improving resistance to cracks and scratches compared to earlier versions.

Refined Design in 7T Models

The OnePlus 7T and 7T Pro take the design a step further with a slightly curved glass back, enhancing ergonomics and improving grip. This curvature makes the phone more comfortable to hold and reduces the likelihood of accidental slips.

Notably, the Misty Silver variant of the OnePlus 7T features a frosted glass finish created through a specialized etching process. This not only gives the phone a sophisticated, matte appearance but also increases surface friction, making it less prone to fingerprints and drops. The finish also resists smudges better than glossy alternatives, maintaining a clean look over time.

Durability Features and Real-World Performance

IP68 Water and Dust Resistance

All OnePlus 7 series devices are rated IP68, meaning they are fully protected against dust ingress and can be submerged in up to 1.5 meters of freshwater for 30 minutes without damage. This rating makes them highly resilient in everyday scenarios—such as rain, spills, or accidental drops in sinks or puddles.

While IP68 does not cover saltwater or prolonged submersion, it provides substantial peace of mind for users who demand reliability in unpredictable environments. However, it's important to note that water resistance can diminish over time due to wear and tear, so regular exposure should be avoided.

Pop-Up Camera Mechanism (7 Pro & 7T Pro)

The OnePlus 7 Pro and 7T Pro feature a motorized pop-up front camera, eliminating the need for a notch and enabling a true full-screen display. Despite initial concerns about mechanical vulnerability, OnePlus engineered this mechanism to be highly durable.

The camera module is rated for over 300,000 actuations—equivalent to more than five years of average use. It includes dust and water resistance features, and automatically retracts if it detects an impact (e.g., when the phone is dropped). Additionally, the motorized system is designed to operate smoothly even in cold temperatures and dusty conditions.

Best Practices for Long-Term Durability

Note: IP68 certification is based on laboratory conditions and does not guarantee permanent water resistance. Damage from liquid exposure may not be covered under warranty. Additionally, the pop-up camera, while durable, should not be manually forced or obstructed. Following manufacturer care guidelines ensures optimal longevity and performance of your OnePlus 7 series device.
