The iPhone 4 used to be the “Apple enlightenment” of many people, and it’s not too much to say that it’s a magic machine. I still remember the shocking feeling on the screen when I first saw this phone, but looking back at the release time, it has been ten years. I never thought Apple would bring back the right angled edge design, and it would be four at a time. < / P > < p > the world has changed in the past decade. The iPhone, which once changed the world, is now back to the angular solution. < / P > < p > the design of right angle frame has been leaked for half a year. The iPhone 12 is made of aluminum alloy with front and rear glass, and the iPhone 12 Pro is made of stainless steel frame with frosted glass on the back. Ten years ago, someone called this kind of design sandwich structure, a very vivid name. Today’s Sandwich technology is obviously much better than it was a decade ago. Compared with any detail or joint on the fuselage, the improvement of delicacy and craftsmanship can be seen at a glance. < / P > < p > with these 10 years in hand, everyone has a story mixed with surprise and hardship. Apple, of course, is changing its roles and products from challengers to being challenged. < / P > < p > the screen has changed. The iPhone 4 with only 3.5-inch retina screen has been amazed by us. Ten years later, the 5.4-inch iPhone 4 is just in its infancy. My medium-sized iPhone 12 and large-sized iPhone 12 Pro have reached 6.1-inch. < / P > < p > although it has edges and corners from a distance, its grip feeling is improved because it is narrow and thin, and the chamfering is properly handled. Before getting the real machine, many people may think that it should be better to hold the arc-shaped frame, but when the machine gets the hand, the right angle frame is far more comfortable than expected. < / P > < p > Apple has always been good at shaping aesthetics, and the straight up and down edges are easier to accommodate more components, and the fall resistance performance is better than that of arc-shaped edges. The film sticking party is finally relieved that there is no need to compete with the arc glass. < / P > < p > although it is not disassembled, we believe that its internal structure must also have great changes. For example, the SIM card slot has changed from left to right, which means that the motherboard should also change its position. < / P > < p > looking back at Apple’s products, the most impressive style change is from 2007 to 13, when the IOS 7 interface directly switched from quasi materialization to flattening; from 14 years to today, from iPhone 6 to iPhone 12, the body switch from arc to right angle is exactly 6 years, which Is it to prevent the legendary seven-year itch?

maybe many people will make complaints about Apple’s price or closeness, but their product’s work has never been disappointing. This is not a matter of detail. On this basis, Apple will give full play to the texture of materials. < / P > < p > in an interview with ive many years ago, he said that one of Apple’s design principles is to let each material give full play to its own texture, and this tradition has always been retained. < / P > < p > so we can see that iPhone 12 is aluminum alloy matte frame + front and rear glass, but glass is glass, metal is metal, each material has its own texture. With a variety of easy colors. Color is very jumping off, eye-catching human and animal harmless, coupled with not so high price, suitable for most users. < / P > < p > on the iPhone 12 pro, it’s a polished surgical grade stainless steel, brighter, colder and harder. Put the two together, you can clearly see the advanced sense and different temperament of pro. It seems that from 16 to 26 years old, you wear a handsome suit and comb your hair into the appearance of an adult. < / P > < p > If I don’t think about photography or the so-called advanced sense, I prefer the iPhone 12 because it weighs only 162 grams. Yes, in this era of large screen mobile phones, it’s lighter within 180 grams. < / P > < p > of course, with or without pro, they all have the same heart (A14), the same interface, and similar performance. Although the ram of 12 is 4GB and that of 12pro is 6GB, this is more reflected in multi task processing. < / P > < p > this is actually an “apple” way. In order to ensure fluency, they will not make too much difference in the basic experience of products using the same chip in the same year. This is true even with the emperor’s iPhone 11 Pro Max and the beggar’s se of the same year. < / P > < p > the difference between pro and non pro is in addition to appearance, material and temperament as well as photography. For example, although their screens are all 6.1 inches, with the same material, the same resolution (2532×1170), the same pixel density (460ppi), the same HDR display, the same primary color display, the same P3 wide color gamut, and the same 2 million to 1 (contrast), the typical brightness of the screen is different, 625 vs. 800 nit, which means that the latter is in most cases It looks more beautiful and transparent. < / P > < p > by the way, this year’s iPhone screen has an invisible improvement. They all use super ceramic crystal panels and ceramic as glass substrate to increase the screen hardness and the phone’s fall resistance. The official claims that the drop performance can be increased by 4 times. Students who don’t like to wear mobile phone covers call experts. < / P > < p > put the two together, the iPhone 12 is obviously simpler (or even more crude) than the iPhone 12 pro. However, the difference between the two in the result of photographing is not so far as expected. < / P > < p > this time, both iPhone 12 and 12pro are 12 megapixel wide-angle main lens + ultra wide angle lens. The wide-angle aperture is ƒ / 1.6, and the super wide-angle aperture ƒ / 2.4 aperture. In addition, the 12 Pro also has a long focus + laser scanning radar. < / P > < p > last year’s iPhone 11 series should be said to be new, and people feel it deeply. This year, it is an improvement on the basis of last year. Now look for four pictures to compare. This is iPhone 11 vs. iPhone 12, and iPhone 11 Pro vs. iPhone 12 pro. It can be clearly seen that the generation of 12, regardless of whether it has pro or not, is more transparent when shooting the same scene – and this kind of transparency is not only clearer in color, but also more appropriate in noise control; especially in dark places. (for details of this part, please see the top video) < / P > < p > for the other 11, we all know that although the night shooting mode was added last year, the super wide angle and long focus night shooting are actually a little bit of a stretch. Apple only gave the ability of night shooting to the main lens, and this year it finally gave two more. < / P > < p > and the angle of view of the ultra wide angle camera is also as large as 120 degrees. Compared with the iPhone 11, you can see that its wide-angle camera can capture more things and control the distortion better. < / P > < p > Apple didn’t introduce itself. In 2020, it still insisted on 12 million pixels, but less than 100 million pixels. This is not only the performance of optical adjustment ability, but also the embodiment of computing power. The development of mobile phone images has long been no longer simply bigger than who has more pixels. More is the improvement of optical performance and computing power, and the chip guides the photographing. < / P > < p > the most obvious case of machine participation in photographing is the portrait mode, which creates a studio like effect through the algorithm, allowing the chip to influence or even produce light. The iPhone 12 series has also improved in this part. We found a streetlight and tried it. We can pay attention to the natural effect of the background virtualization, the excessive light level from the shoulder to the lower arm, and the texture of the clothes. < / P > < p > let’s talk about one thing unique to the iPhone 12 pro, the lidar lens, which we’ve seen on the 2020 iPad pro. On mobile phones, of course, it can still be used as a rangefinder, but using it only as a ruler or calculating area is overkill. In fact, the official rangefinder is more like a demonstration app, and the imagination space is left for developers. < p > < p > Apple has developed more functions for lidar this year, such as improving the speed of night scene focusing. In a dark environment, the autofocus speed of lidar within the range of about 5 meters is significantly faster (the official claim is 6 times higher). < / P > < p > with regard to taking photos, what we have seen is not the strongest performance of the iPhone 12 series this year. Apple proraw will be updated later. There is also the most anticipated iPhone 12 Pro max, which said at the press conference that the sensor size of its wide-angle camera has increased by 47%, the pixel size has increased to 1.7 μ m, and the low light shooting performance has improved by 87% — the rounding is basically 100%. We are looking forward to the appearance of this mobile phone. < / P > < p > the so-called “Dolby horizon” is an image quality technology launched by Dolby laboratory, which improves the image effect by improving brightness and expanding dynamic range. It can improve the fidelity of video signal, so that the image is very lifelike from the perspective of brightness, color or contrast. On some video apps, we can actually see the corresponding support. < p > < p > Dolby horizon is a system, which needs hardware + software support. This time, apple added an iPhone camera system to the iPhone 12 and 12 pro to capture Dolby’s view video directly. In fact, it has entered the level of manufacturing content. Of course, there is a difference between the two. The Dolby horizon of the iPhone 12 Pro is 60 frames, and that of the iPhone 12 is 30 frames. < / P > < p > the iPhone can not only shoot, but also clip Dolby view video on the device, play it with airplay, and generally put 4K Dolby view video on compatible devices. < / P > < p > so you see, apple supports a standard, it has to be implemented from the beginning to the end: iPhone 12 and 12 Pro fully support Dolby’s vision from shooting, editing, playing and sharing. This method is very apple, and only apple has it. < p > < p > for various reasons, Apple’s mobile phone didn’t catch the first 5g bus. Last year, a lot of people thought that Apple was behind. This year, if you ask these people what you have done with 5g, it seems that they have not done anything < / P > < p > in this year, China vigorously developed 5g mobile phones, and domestic mobile phone manufacturers almost only made 5g mobile phones. Now, penyou in the first and second tier cities may have experienced it. < / P > < p > but to be honest, there still seems to be no need to use 5g at present. Maybe that’s why Apple has made an intelligent mode “automatic 5g” for its mobile phone. Only when 5g is necessary can it be used to balance network speed and power consumption. In addition, some foreign media said that if two 5g cards were put into an iPhone 12 at the same time, there would be only 4G. It could be a misinformation. We measured the actual shipment of iPhone 12, and loaded two 5g cards at the same time. One card was 5g, and the other card voice and Internet phone were not delayed. < / P > < p > of course, 5g is not used to run points. In daily use scenarios, the more obvious experience is that when you download the app, iPhone with 5g support is much faster than 4G. When watching videos, the highest image quality is almost no buffer time. < / P > < p > for now, 5g may still be in the early stage. The high-speed road and the cars on it, that is, the Internet and 5g mobile phones, are ready. Users can drive high-performance cars on the highway, but where is the goal? What is it? I’m not sure. < p > < p > it’s app developers who have to work hard. That’s why 5g iPhones are important: for the average user, it’s finally possible to have a 5g network on the system they like; but more importantly, it’s Apple’s call to the industry
