Every year, after the iPhone goes on sale, all kinds of reviews about the phone are springing up, and the content involved is also carried out in different directions, including the “violence test”. This year’s iPhone 12 and iPhone 12 Pro went on sale last Friday, and many foreign bloggers have conducted many extreme tests on these two models, including those for anti falling, screen scratch resistance and waterproof. < p > < p > especially this year’s iPhone 12 series screen is equipped with super ceramic technology, apple said that its anti drop ability has been increased by four times, which also makes many people think of “running naked”. Before you make up your mind, these violent tests may be used as a reference other than the official’s speech. < / P > < p > this year’s iPhone 12 series uses a flat metal frame and a flat panel, so the screen is completely wrapped by a metal middle frame, so it is not easy to transfer the force to the screen when it falls, resulting in broken screen. In addition, Apple has also introduced hypermagnetic crystal technology, which has significantly improved the hardness of the screen. In order to verify the anti drop performance of iPhone 12 and iPhone 12 pro, Allstate protection plans, a mobile phone insurance company from the United States, specially recorded a test video: they set up a 1.8-meter-high bracket on a piece of cement outdoor, and tested the iPhone 12 / iPhone 12 Pro respectively The anti drop performance of the fuselage is achieved under three kinds of drop cases, i.e. screen down, back cover down and middle frame down. < / P > < p > the results show that the iPhone 12 test results of aluminum metal middle frame and glass back cover are better, only screen cracks appear in the screen down test, and the other two tests only cause some bumping marks on the aluminum middle frame. That’s a lot better than the iPhone 11 they tested last year, and Allstate protection plans even said the iPhone 12 was the best drop resistant phone they tested. < / P > < p > in the screen down test, the scope of screen cracks of the iPhone 12 Pro is larger, and in the test with the back cover facing down, the integrated frosted glass back cover almost has crushing damage, even the protective cover of one of the lenses cannot be spared, but the function of the hand-held machine has not failed. My guess is that the reason for this contrast may be that the iPhone 12 Pro is heavier and will inevitably experience more pressure when it falls. < / P > < p > it is worth mentioning that this test result is still better than last year’s iPhone 11 pro, when the iPhone 11 Pro was in the face-down drop test, not only the screen cracked, but also the touch function failed. < / P > < p > in the Mohs hardness scale test, the iPhone 12 pro, like other smart phones, stays at the level 6 hardness standard. At this time, the screen begins to show small scratches, and the scratch depth will be more obvious on the screen under the 7-level standard. Although Zack Nelson (up owner) said the scratches on the iPhone 12 pro in the six hardness test were “dimmer” than other phones, the difference was not significant. < / P > < p > the stainless steel middle frame of iPhone 12 Pro continues the PVD (physical vapor deposition) process of iPhone 11 Pro last year (except the golden version). This process allows apple to coat the stainless steel with the color matching the body color. However, according to the test of Jerry rig everything, the common knife can easily damage the coating of the middle frame. < / P > < p > in addition, some people may worry about whether this year’s thinning of the iPhone 12 will cause the fuselage to be easily bent. Zack Nelson also tested this point. From the video, it can be seen that he almost made the “sucking strength”, and the iPhone 12 Pro still did not move. < / P > < p > another YouTuber mobile review eh uses a push-pull tester to test the screen hardness of iPhone 11 and iPhone 12, with the values of 352n and 443n respectively, which means that the screen of iPhone 12 can withstand more external force before physical cracks appear. < / P > < p > of course, these tests are not carried out under controlled laboratory conditions, so there are many uncertain factors, and the results are not necessarily accurate, which can only be said as reference. After these violent tests, are you going to let the iPhone 12 run naked? Apple extends AppleCare + purchase period: users can decide within 60 days
