Scratch Resistance vs. Wear Resistance: The Balance Apple Found in Ceramic Shield 2
What You Need to Know
- Apple’s new Vice President of Hardware Engineering, Tom Marieb, said that seeing someone using a screen protector on their iPhone “gives me the creeps.”
- The statement reflects Apple’s confidence in Ceramic Shield 2, which, according to the company, offers up to 3 times more scratch resistance than previous versions.
- The new iPhone Duo, Apple’s first foldable, will also feature Ceramic Shield 2 and a hinge designed to convey a greater sense of solidity.
When Tom Marieb, Apple’s new VP of Hardware Engineering, sees someone put a screen protector on an iPhone display, his reaction is blunt: “It makes my skin crawl.”
The comment, made during a press roundtable at Apple’s London headquarters with TechRadar, sums up the company’s confidence in Ceramic Shield 2 — the glass featured on the iPhone 18 Pro and on the outer display of the highly anticipated iPhone Duo, set to launch on October 23.
The Challenge of Perfect Glass
According to Marieb, the team pushed hard to create front displays that were both beautiful and durable. The biggest engineering hurdle was balancing two qualities that typically work against each other:
- Scratch resistance: withstanding sharp objects in everyday use.
- Wear resistance: keeping the surface intact after years of continuous use.
“We could have made it more scratch-resistant, but it would have been a little less wear-resistant. It’s the long service life we’re after,” Marieb explained.
Ceramic Shield 2 delivers up to 3 times more scratch resistance than previous versions. To validate that, Apple ditched old military-spec testing and instead started simulating five years or more of real-world use in just a few weeks in the lab.
The iPhone Duo Challenge
Beyond the new glass, Apple’s first foldable phone demanded extra attention to the hinge. The goal was to give users complete confidence in the mechanism:
- A feeling of solidity: Apple fine-tuned the torque profile so the device closes with the same firmness as “a luxury car door.”
- Matte nanotexture display: the matte finish on the inside cuts down on glare and makes crease lines far less noticeable over time.
The Duo also arrives with an IP68 rating for water and dust resistance — higher than the Galaxy Z Fold 8.
Despite Apple’s confidence and the technical advances, many users still hesitate to ditch their screen protectors. Whether it’s fear of steep out-of-warranty repair costs or the search for extra privacy and anti-glare filters, that protective layer remains a hard habit to break.
