iPhone 12 Scratch/Drop Test: “Ceramic Shield” is really enough shield

Apple has installed a new type of glass called a “ceramic shield” on its new iPhone 12, which is said to be the hardest glass ever used on a smartphone,media reported. Every year Apple makes a similar statement about its glass, but this time it may be different because it’s not ordinary glass. Although it looks and feels no different from ordinary glass, the ceramic shield covering the screen, as its name suggests, is a combination of glass and ceramics – harder than most metals.

To find out how hard the new material is,media CNET tested two new iPhone 12s for scratches and drops. The new glass has proved to be very durable.

It is reported that the ceramic shield layer only covers the screen of the iPhone 12. The back is still using the same glass as last year’s iPhone 11. Apple says last year’s iPhone 11 was the strongest in the industry. Both types of glass are made by Corning.

In addition to glass, another factor affecting the phone’s performance when it drops may be its design. The iPhone 12’s glass is level with the metal frame, rather than bending like previous models, leaving more glass exposed. Apple says design choices alone can make the front and rear ers twice as durable as the old ones.

All four models of the iPhone 12 (iPhone 12 Mini, iPhone 12, iPhone 12 Pro and iPhone 12 Max) use the same ceramic screen and back glass. The only difference in material is the frame. Both Pros feature stainless steel frames, while the Mini and 12 are aluminum frames. The performance of the frame may vary depending on the material, but glass should provide the same type of protection. In tests with CNET, they used the regular blue and green iPhone 12.

Scratch Test 1: Pocket/wallet roll over

In the first test, the reporter put the iPhone 12 in a small make-up bag containing some common things that damaged the phone: a string of keys, half a dozen 25-cent coins and a metal pen. The reporter shook the bag for about 30 seconds to simulate what would happen after a few weeks of playing in his wallet or pocket before checking it.

Finally, when the reporter wiped the phone with a cloth, he found no scratches on the glass or frame of the iPhone 12.

Scratch Test 2: No scratches on the screen after sliding on the tile

Next, the reporter wanted to see how the screen was supported when it came into contact with hard surfaces such as marble tables, kitchen counters or bathroom floors. The reporter swiped the iPhone 12 10 times back and forth on a tile, first with a screen and then with the back of the phone.

As a result, there are fragments of tiles on the screen, but it is difficult to find any noticeable glass damage after wiping it clean. Testing the back of your phone can be tricky. The raised camera module does not allow the phone to be flat, so the reporter slides the back at an angle. This did not damage the glass, but caused some metal paint on the bottom camera frame to fall off. Then the reporter extended the camera module to the edge of the tile. After examining the back carefully, the reporter finally saw two subtle scratches, one on the silver apple sign and the other directly below the blue glass. They are all thinner than a strand of fine hair, about a third of an inch.

Scratch Test 3: Wipe a mark on the sandpaper

After brilliantly passing two scratch tests, the reporter decided to do another extreme test of the iPhone 12: polished with 80 pieces of sandpaper. This could be the equivalent of sliding a phone across a driveway or sidewalk in the real world.

The reporter rubbed the phone back and forth on sandpaper 10 times and applied slight pressure. This time, both sides of the phone were scratched. The screen is the most damaged. Several of the damaged parts were very deep, and the reporter said his fingernails could be touched but his cell phone could still be used. Damage to the back of the phone is much smaller, which is also because the raised camera module provides protection, but there are still visible bruises on the center and lower edges. The metal on the lens frame continues to fall off, but there are no scratches on the lens itself.

Friction can damage the phone’s glass, and it’s more likely to damage the phone when it falls, so CNET tested it on the sidewalk with another brand new iPhone 12.

Drop Test 1: Drop height 3 feet, screen facing down

One of the most common drops is when you put your phone in or out of your pocket. While it’s harmless for a phone to fall high above your hips, it can break the screen if it falls on a street or sidewalk.

When the iPhone 12 falls from the hip height, the top will fall first and then the bottom. After that, it bounces up again in the air and lies flat on the sidewalk, with one side of the screen facing down as expected.

As a result, the phone’s aluminum body has several dents on the edge, but the damage is not severe.

Drop Test 2: Drops 3 feet high with the back facing down

The next drop test was the same as the first one, but this time it was the back of the phone facing down.

The top of the iPhone 12 seems heavy: it lands almost as before, first at the top and then at the bottom, and finally on the sidewalk.

The main difference with this drop is that it sounds louder when it lands than before. Sure enough, the lower half of the phone broke when it turned it over. The edges of the phone feel a bit rough, but no debris falls off the back and feels smooth despite the cracks.

Drop Test 3: Drop height 6 feet 6 inches, screen facing down

In this test, the most obvious dent appeared at the top, but after wiping it, the reporter found that it was just metal residue on the phone frame, but the glass was still intact.

Drop Test 4/5/6: Drop height 9 feet, screen facing down

As the screen was still strong, the reporter decided to climb higher and climb nine feet with a ladder. It’s important to note here that unless you happen to slide your phone off the second-floor balcony, it’s an unrealistic drop, but foreign correspondents want to see how far we can slide it.

At an altitude of 9 feet, controlling a landing becomes more difficult. When the reporter crafted it flat on the screen, the iPhone 12 had its own idea and landed almost identically on the 6-foot-tall ground. The top right corner of the screen hits the ground first, then bounces back from the left, landing on one side of the screen facing up.

The dent in the top right of the phone’s border is deeper, but the screen survives.

The reporter repeated the process twice in the hope that it would face the ground at some point, but the weight of the camera made it difficult to get to that angle, especially at that height. Perhaps the only way to control it is to climb on the roof or rent a scissor lift, but journalists are not prepared to do so.

Summarize.

CNET says that because their tests aren’t scientific, they can’t guarantee that the iPhone 12’s screen is stronger than any other phone on the market, but they can safely say that the iPhone 12 is absolutely as hard as it is, even if it falls on tiles and sidewalks.

“The iPhone 12 and iPhone 12 Pro represent the biggest leap forward in the iPhone’s durability . . . The iPhone 12 has passed rigorous reality testing and is designed to be durable, but not indestructible. If someone is worried that their iPhone will be damaged if it falls to the ground, we recommend using a nice case to protect it. “
