iPhone 12's Ceramic Shield is tougher than glass!

Apple’s new iPhone 12 models feature a new ceramic-hardened display named Ceramic Shield. Apple says Ceramic Shield is “tougher than any smartphone glass,” with four times greater resistance to damage from drops.  Apple says that Ceramic Shield is made by introducing nano‑ceramic crystals — which are actually harder than most metals — into the glass which dramatically improves the toughness. 

The iPhone 12 and 12 Pro was available to the public Friday, October 23, and as soon as people got their hands on it, some of the YouTubers and bloggers started to test out iPhone’s durability. The durability of the iPhone 12 screen using a force meter was compared against last year’s iPhone 11. According to this type of test, the iPhone 11 screen will break when 352 Newtons of pressure is applied. The iPhone 12, however, can withstand 443 Newtons of pressure before breaking.

People also tested its ability to scratch and other minor screen durability, As expected, the iPhone 12 is able to withstand scratches from things like coins, keys, and a box cutter. Using a Mohs hardness test, the 6 and 7 points leave clear scratches on the ‌iPhone 11‌, while the iPhone 12 can withstand the 6 points but is still susceptible to the 7 point test. These models could easily survive up to 10 feet of drop tests. The front screens on the iPhone 12 and iPhone 12 Pro were able to survive up to a 10-foot fall flat on their faces with minimal glass damage. That same fall onto the backs of the phones shattered the rear glass on both since the back glass is just made of normal glass material and the edges weren't particularly durable to the drop.

In the worst-case scenario, if you accidentally break the glass of your new iPhone 12, Apple will charge you the same $279 to replace it as it did the iPhone 11 Pro's glass. The iPhone 12's new OLED display also costs $279, which is $80 more expensive to replace than last year's iPhone 11's LCD panel. This is certainly a good start for the iPhone 12 lineup but we'll need to see how these things hold up out in the real world.
