In the lead-up to the official launch of the iPhone 18 Pro, Apple’s newly appointed Vice President of Hardware Engineering, Tom Marieb, shared insights into the durability features of the upcoming iPhone 18 Pro and the iPhone Duo. A key highlight is the Ceramic Shield 2, a type of display glass that was first introduced with the iPhone 17 and is now returning with the iPhone 18 Pro. This material is said to offer three times better scratch resistance than previous models, marking a significant improvement in protecting the phone from everyday wear and tear. Marieb, who previously served as Apple’s CEO before transitioning to his current role, emphasized the company’s focus on creating products that can endure long-term use. He explained that the development of Ceramic Shield 2 involved finding a balance between scratch resistance and overall wear resistance—two properties that often conflict in materials science. Apple’s testing procedures are designed to simulate years of use in a short period, ensuring that the devices meet high standards of durability before reaching consumers. The iPhone Duo, which is set to launch next month, introduces new challenges in terms of durability, especially with its foldable hinge. Marieb expressed confidence in the hinge’s design, which is intended to feel solid and reliable whether the device is being opened or closed. The hinge’s torque profile—how it resists or allows movement—was carefully optimized to provide a robust feel, akin to the mechanism of a high-end car door. This attention to detail aims to ensure the device remains functional and sturdy over time. Another notable feature of the iPhone Duo is its 7.6-inch nano-texture display, which not only enhances the device’s visual appeal but also helps maintain the obscurity of the hinge area. This matte finish is designed to reduce glare and provide a more forgiving surface that can better handle changes in appearance over time. These design choices reflect Apple’s effort to combine practicality with aesthetic appeal, ensuring the iPhone Duo is both visually pleasing and durable.
