2020 is coming to an end, and this year’s major manufacturers’ blockbuster models have all debuted. When I opened the video website and searched for videos of various new mobile phones, I found that the more “cruel” durability tests were performed than the videos played on the new mobile phones.
Every year after the release of a new mobile phone, it means that it will pass the brutal certification of netizens. It is beyond recognition the standard end of each durability test, and each mobile phone competes against who can persist for longer. Unexpectedly, there have been several “hard stubbles” in the sea this year.
One, almost unbreakable front panel
Each generation of iPhone is the protagonist of the durability test of the year. It is not so much that the audience wants to know whether the new iPhone will be more resistant to construction, but rather they are more keen to watch this one that represents precision and expensive Mobile phones were ruthlessly tortured and tortured. This year’s iPhone 12 is no exception, it has experienced torture once it was released.
Bending the iPhone with bare hands is naturally an annual dish, but after years of upgrading materials and craftsmanship, It is almost impossible to bend the iPhone with bare hands.
If the bending, falling, and scratching of the simulation of real use scenarios belong to the realism genre in the durability test, then the test of wrapping the iPhone 12 in wax and then falling from a height is Dadaism for modern technology Reinterpretation.
What should I do if my phone accidentally falls into the pot when making cola chicken wings? Not as good asThe performance may be beyond your imagination. In a test conducted by video blogger Filip Koroy, he dropped an iPhone 12 Pro Max from an 11-foot (about 3.35 meters) in the air. After landing, the middle frame of the mobile phone was deformed, the back panel was torn apart, the camera was not working properly, and the display also had problems such as liquid leakage and dead pixels.
On the other hand, looking at the super-ceramic glass panel on the front, it is still intact except for a few scratches.
The previous generation of iPhone 11 did not perform badly. In a drop test under the same conditions, the iPhone 11 can also hold up to 6 feet(about 1.8 meters) Falling and not breaking, it is also rated as the most durable glass in the past, but in the face of super-ceramic glass, it is obviously still a younger brother.
According to Apple’s introduction, the super-ceramic glass used in the iPhone 12 was jointly researched by Apple and Corning. The principle is to add nano-scale oxide ceramic crystals in the glass manufacturing process to finally obtain high light transmittance. Strength of the glass panel.
This material between glass and ceramic is also called microcrystallineGlass, in fact, we are no stranger to this material in our lives. If you have an induction cooker at home, its panels are basically glass-ceramic panels.
Of course, this does not mean that the induction cooker panel is as “high-end” as the super-ceramic crystal glass. Although the crystal-ceramic glass has excellent characteristics such as high hardness, wear resistance, thermal expansion and contraction resistance, you must apply it to On the mobile phone screen, we must face the two problems of making it thin and making it “through”.
To solve these two problems, a very high level of production technology is required. This is why despite the excellent drop resistance of glass-ceramics, before Apple’s super-ceramic glass appeared, almost no mobile phone manufacturers could apply it to On the phone panel.
In order to make the super-ceramic glass thinner while increasing its light transmittance, Apple and Corning jointly developed a unique formula to control the type and crystallinity of the crystals in production, so that the volume of these fine crystals As small and uniform as possible.
The principle sounds easy, but it is actually very difficult when the glass is actually produced. Because the added ceramic crystal does not transmit light, if you want to have good optical transparency, you must grasp the crystal formation during production. A slight deviation of the temperature, time and heating rate of the nucleus will cause the crystal to be too large or incomplete, which will affect the light transmittance and strength of the glass.
Compared with the Gorilla Glass we are familiar with before, Super Porcelain Crystal Glass has (a new formula with porcelain crystal particles added) and table (more complex processing) process innovation, but also has a 4 times improvement in drop resistance.
It is a pity that the iPhone 12 series only uses super-ceramic glass on the front panel, and on the back panel, it still uses double ion exchange strengthened glass that is the same as the previous generation.
Although the strength of the back panel glass is still at the top level, it can be seen in the drop test that there is still a large distance from the super-ceramic glass, so the protective case is still the only way to protect your love select.
Second, a back shell that takes into account beauty and durability
The material of the mobile phone is a cycle like the fashion circle. Several materials such as plastic, metal, glass, etc. take turns to play the leading role on the mobile phone. Looking at the back shell of this year’s new machine, we can see that the most popular material this year is glass that has undergone various treatments.
However, these processes are more about the pursuit of visual breakthroughs, making the appearance of the phone look more advanced, rather than enhancing the strength of its glass.
Even though these glass back shells look less and less like glass, when you accidentally slip the phone and drop the phone to the ground, the crack on the back will stillReveal the fate that is inevitable as glass.
Before new materials like super-ceramic glass are used in the backplane, if you want to coexist with beauty and durability, the ceramic back cover may be the best solution at present.
The use of ceramics for mobile phone back covers is nothing new, as early as OnePlus X, Xiaomi Mi 5, Xiaomi Mix and other models have been tried, but because the ceramic back covers have more production processes than glass back covers Difficult, so these products are either very small in production or expensive.
However, as the processing technology matures, ceramic back covers are gradually entering mainstream shopping malls. This year, Huawei has adopted ceramics as the back cover material on P40+, Mate40+ and Mate40 RS. Huawei claims to use “Nano-microcrystalline ceramics”, which still has the unique texture of crystal clear and warm ceramics from the appearance. , But what is more impressive is its fall resistance.
From the drop test conducted by Xinping Technology, the P40+ using nano-microcrystalline ceramics, after 10 drops from a height of 1.5 meters to a slate, the back shell is still unharmed, which is in sharp contrast. Yes, its front panel has changed beyond recognition.
For comparison, how about the glass back of Huawei’s new flagship series Mate40 Pro? Xinping Technology also used it for testing. Judging from the test results, it was the same as expected. The first time it fell, it was broken and safe.
This result is naturally reasonable. The hardness of ceramics naturally exceeds that of glass. After nano-crystal processing, the overall strength and toughness of the material has also been greatly improved. For now, Huawei’s nano-microcrystalline ceramic back shell is one of the most resistant back shell materials.
3. The durability of mobile phones is still worthy of our attention
According to a recent Toluna global consumer survey data, people drop their mobile phones 7 times a year on average, which means that even if we use them carefully in daily use, it is difficult to avoid close contact between glass and the ground.
