iPhone 12, what are the details you need to pay attention to?

If we followed the rule of “inter-generational upgrade”, this year’s new iPhone should have ushered in a generation with the “S” suffix.

But since Cook announced the iPhone 12, you already know that this year’s iPhone will not be as simple as changing the name.

iPhone 12 mini, iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max, this is the first time Apple has launched 4 new iPhones of different sizes and models.

They have also changed quite a lot-relying on the new design, the four iPhones have broken away from the rounded bezels that have been used in the past 7 years and have returned to the tough era.

Not only the appearance has changed, but the screen, performance, camera and even charging methods have been improved for the iPhone 12.

In addition to the flat middle frame, what other changes have been made to the appearance?

After two years, iPhone 12 once again ushered in a change in appearance.

The most obvious difference is on the side. The middle frame of the 4 iPhone 12s has become flat, instead of the rounded surface before.

Many people compare the new design of the iPhone 12 to a “Renaissance”, because in the iPhone 4 and 5 era, Apple has already adopted this square design.

However, in terms of craftsmanship, iPhone 12 still has many differences from its predecessors.

▲ CNC cutting of iPhone 5

You should remember the chamfered bright surface on the side of the iPhone 5, which is actually made by Apple using the diamond cutting process.

▲ iPhone 12 and 12 mini use aluminum alloy frames, while 12 Pro and Pro Max are made of stainless steel

But on the iPhone 12, Apple prefers to use a natural arc transition, so that the metal middle frame and the front screen panel and the back cover glass are smoothly attached together.

From the side view, this is very similar to the previous iPad Pro’s handling.

▲ The iPhone 12 uses an iPad Pro-like Founder design

Although it is only a very small adjustment, it still affects the feel of the hand when it is reflected on the real machine. After all, the beveled edge of the iPhone 5 was complained of “cutting hands”, and the rounded corners can make the edge processing more smooth.

As for large-size machines like 12 Pro Max, whether the shape design of the Founder will challenge the grip remains to be verified later.

▲The first Apple device to switch to a flat frame is not the iPhone 12, but the 2018 iPad Pro

Apple did not explain the reason why the iPhone 12 switched to a flat frame at the press conference, but former Apple designer Jonathan Ivey talked about the design change of the iPad Pro in 2018 .

He said that when Apple’s design team can make the iPad thin enough (the new iPad Pro was only 5.9 mm thick at the time, and the old one was 6.1 mm), there is no need to rely on curved surfaces to create a visual “thinness”.

The same is true for the iPhone 12. After all, it is light and thin, and it has made a lot of progress over the previous generation.

In addition, it can be seen from the side view that iPhone 12 has adjusted the structure of the screen panel. It is no longer 2.5D glass with curved edges, but a completely “pure plane”.

This is related to the new panel technology used in the iPhone 12, which we will explain further below.

The results of the above adjustments are ultimately reflected in the weight and thickness of the iPhone 12 series.

Let’s take a look at a set of iPhone’s weight and thickness data:

iPhone 11: 194 grams, 8.3 mm
iPhone 11 Pro: 188 grams, 8.1 mm
iPhone 11 Pro Max: 226 grams, 8.1 mm
iPhone XR: 194 grams, 8.3 mm
iPhone SE second generation: 148 grams, 7.3 mm

The data for the 4 new iPhones this year are:

iPhone 12 mini: 133 grams, 7.4 mm
iPhone 12: 162 grams, 7.4 mm
iPhone 12 Pro: 187 grams, 7.4 mm
iPhone 12 Pro Max: 226 grams, 7.4 mm

This set of data is very eye-catching. First of all, the thickness. I am surprised that Apple has unified the thickness of the four iPhone 12 models to 7.4 mm, which is basically the same as the second-generation iPhone SE.

In terms of weight, the two Pro models have not changed much, and the weight of the iPhone 12 is much lower than the previous generation 11 and XR.

The best is the 12 mini, which is only 133 grams, which means it is lighter than the iPhone 8 and the second-generation iPhone SE.

The whole system relies on OLED, no more compromises on the screen

For many users, this year’s iPhone 12 can match the Pro version flagship in the screen part, which should be Apple’s most meaningful “addition.”

I say this because this year, in addition to the iPhone 12 Pro, even the 12 and 12 mini have adopted super retina XDR displays, which are the same models as the iPhone 11 Pro/Pro Max.

This change also significantly improves the screen quality of the two non-Pro iPhones, such as HDR display, 460-470ppi screen pixel density, higher contrast, higher brightness, etc.

The above features are features that the iPhone 11 and XR previously equipped with LCD screens could not have.

After the unified use of the Super Retina XDR display, the screens of the 4 iPhone 12s no longer have differences in color and contrast. The non-Pro version and the Pro version only have slight differences in the highest brightness.

Even the black edges of the front screen are the same for all 4 models.

In terms of size, the iPhone 12 is still 6.1 inches, and the 12 Pro is also upgraded from 5.8 to the same size.

▲ Do you want a small screen flagship? Just choose 12 mini

After the iPhone 12 mini switched to a full screen, Apple was able to pack a 5.4-inch screen in a body smaller than the iPhone 8, which is basically the “small screen flagship” that many people dream of.

The screen size of the iPhone 12 Pro Max is increased to 6.7 inches, which is slightly larger than the 6.5 inches of the previous two generations.

How to achieve 4 times the drop resistance?

The Ceramic Shield is a new process introduced by the iPhone 12. Apple said it can increase the drop resistance of the front panel of the screen by 4 times.

▲ Glass with ceramic hardness

This process is the result of the cooperation between Apple and Corning. It mainly incorporates ceramic crystals into the original glass material. In this way, the glass panel can obtain ceramic-like hardness while also taking into account the permeability of the glass.

According to Corning , the front panel used in the iPhone 12 series is also “the world’s first transparent and colorless glass ceramic.”

In addition, we also mentioned in the previous article that the screen of the iPhone 12 is “flat”, because this design also helps to give the front panel more protection, thereby enhancing the durability of the panel.

Apple and Corning have a long history of cooperation. The former invested more than US$200 million in Corning in 2017 and 2019, with the purpose of allowing Corning to develop new glass materials for devices such as iPhone and iPad.

▲ The glass back of the iPhone 11 Pro is also very resistant to drops

This investment result has been reflected in the iPhone 11 Pro series. At that time, Corning used the dual-ion interactive process to customize a new set of back cover glass for the iPhone. Apple calls this “the hardest glass material in a smartphone.”

▲ The frosted back cover glass of the iPhone 11 Pro will also follow the 12 Pro series

Refined to the processing technology, this glass is also very good. Friends who have used the 11 Pro series should find that its main body uses the AG process to achieve a frosted texture, but the protruding camera area is a polished surface, which means that Apple has made a frosted surface on a whole piece of glass. Two textures and bright surface.

This year’s iPhone 12 Pro series also inherited this unique and solid back cover design, which is very good.

How much is the performance improvement of iPhone 12? This is still a mystery

In September of this year, Apple launched the latest generation of A14 chips based on the 5nm process design, but at that time Apple only gave the comparison data of A14 and A12 instead of last year’s A13.

After that , media including AnandTech gave some speculations based on the official website data . They believed that A14 would be 16% and 8% higher than A13 in terms of CPU/GPU performance.

If the situation is true, the overall improvement of the A14 is not as good as the previous generation A13, which has about 20% performance improvement over the A12 in both parts.

▲ 50% improvement emphasized by Apple, the target is other competing chips

I thought that at the iPhone 12 conference, Apple would give more specific A14 data, but unfortunately, this time Apple still only recounted the characteristics of the 5nm process and 11.8 billion transistors, and basically did not talk about the comparison of A14 and A13. .

As for the “50% performance improvement” mentioned at the press conference, the target is “other competing chips.” It is unknown who it refers to.

In terms of storage, some developers have checked the storage size of 4 iPhone 12 models from Xcode, of which iPhone 12/12 mini is 4GB, and iPhone 12 Pro/12 Pro Max is 6GB. Compared with the previous generation iPhone 11, the 4GB storage has changed.

If you want to understand the real performance of iPhone 12, it is best to wait for the real device to get started, and you will get a more accurate answer.​

Taking pictures is still the focus, the gap between different models is even bigger

Imaging capabilities have become the most obvious part of the new iPhone’s improvements in the past two years. Last year, Apple added ultra-wide-angle lenses to the three iPhones, expanding their field of view and shooting freedom.

On this year’s iPhone 12, the imaging capabilities have been improved again, and the configuration gap between different models is also more obvious.

Let’s first talk about the iPhone 12 and 12 mini. The two are still a dual-camera combination, but the wide-angle lens aperture has been increased from f/1.8 to f/1.6, and the 7P lens has been changed to effectively improve the shooting experience in low-light scenes. The other ultra-wide-angle lens did not change significantly.

As for the iPhone 12 Pro and 12 Pro Max, a LiDAR lidar sensor is added to the original wide-angle, ultra-wide-angle and telephoto.

This sensor has been used in this year’s iPad Pro. It is mainly used to capture depth data and enhance the AR application experience. However, this time the two iPhone 12 Pros used it for the assisted focus, which will be used in low-light scenes. The focus speed has been increased by 6 times, further taking advantage of the ToF sensor.

Another thing worth noting is the camera configuration of the two Pro iPhones. In the two generations of XS and 11, their parameters are basically the same, so no matter which Pro you choose, you can get the same photo experience.

▲ This is equivalent to saying that the iPhone 12 Pro Max has replaced it with a better quality main camera

This year is different. On the surface, there are three cameras plus a sensor, but the wide-angle lens of the iPhone 12 Pro Max is equipped with a new photosensitive element, which directly increases the area by 47%, and the unit pixel area increases from 1.4μm to 1.7μm. Is to obtain better picture quality, and imaging capabilities.
In terms of telephoto, the focal length of the 12 Pro Max lens has become longer, from 52mm to 65mm, which can take better close-up photos, and also supports up to 5x optical zoom and 12x digital zoom.

▲ Sensor displacement technology solves the problem of image jitter by moving the sensor in the body

In addition, the wide-angle lens of the iPhone 12 Pro Max also introduces a new “sensor shift” solution, which is a very mature technology in the camera field.

In the past, the OIS optical image stabilization that we saw on mobile phones mainly used a floating lens group to adjust the path of light entering the sensor to stabilize the image.

The sensor displacement, as the name implies, the moving object changes from the lens group to the sensor. When the body shakes, the sensor in the body will do the corresponding compensation movement.​
In general, the iPhone 12 Pro Max’s camera capabilities will be very “cruel”. Not only will it have a new outsole, but also a new anti-shake solution. Whether it’s for static photography or dynamic video shooting, it will bring significant results. Promote.

▲ The wide-angle and telephoto lenses of 12 Pro and 12 Pro Max are different

For the software part, thanks to the arrival of the A14, the iPhone 12 has received the upgrade of the third-generation smart HDR algorithm, and the ability to directly record and edit Dolby Vision HDR video is still 10bit.

The second is the deep integration of night mode and Deep Fusion. Previously, these two technologies were only applicable to individual lenses. For example, the night scene mode of the iPhone 11 series is not suitable for ultra-wide angle, resulting in a poor filming rate of this lens at night.

But on the 4 iPhone 12s this year, Apple applied these two technologies to all cameras, including not only the ultra-wide angle, but even the front lens is no exception, so I am also looking forward to the low-light selfie performance of this iPhone 12 .

The last item is Apple ProRaw, which is an exclusive feature of the Pro version of iPhone. In fact, it allows users to get the opportunity to output Raw format photos and increase the space for later adjustments. This feature will be provided in a future iOS software update.

Magsafe is resurrected, wireless charging becomes faster

As rumors say, this year’s iPhone 12 box does not have a separate charging head and wired earphones anymore, and only a USB-C to Lightning fast charging cable will be retained.

The reason given by Apple is of course environmental protection, but for consumers, this is indeed a “reduction”, and it is estimated that it will become one of the black spots of this generation of iPhone 12.​

▲ Without the earphones and charging head, there is an extra C to L cable, good or bad?

In terms of charging methods, this year Apple came up with a new plan to resurrect MagSafe magnetic charging that has been abandoned by MacBook.

As you can see from the video and pictures, Apple has inserted a ring magnet structure inside the iPhone 12 body, which allows the corresponding charger to be automatically attached to the back of the body.

There are three main benefits of this design.

First, a higher charging rate. According to official website data, using MagSafe magnetic accessories, the wireless charging power can reach up to 15W, while the traditional Qi protocol is still only 7.5W.

Second, it improves the ease of use of wireless charging. Due to the adsorption effect of the MagSafe magnet, the device can automatically “stick” to the charging board, and the user no longer needs to align the coil position by himself. It can also be used to play the mobile phone while charging.

Third, it is a series of accessories based on magnetic characteristics. We mentioned earlier in MagSafe related articles that the greatest value brought by the magnetic design is the ability to “give the device the attributes of extended connection without destroying the integrity of the product appearance.”

▲ The magnetic charging board shown by Apple has fulfilled AirPower’s last wish

The same is true for the iPhone 12. Now Apple has not only built a special mobile phone case for it, but also a series of card sleeves and new charging accessories, all of which are achieved by magnetic attraction rather than additional openings.

Of course, you have to buy these accessories yourself.

It is foreseeable that in the future, there will definitely be other third-party manufacturers that will create a wealth of MagSafe accessories for the iPhone 12. The new accessory business is beckoning to Apple.

With 5G, it’s time to switch to Qualcomm baseband this time?

Before the release of the iPhone 12, many friends were still speculating about what the phrase “Hi, Speed” means on the Apple warm-up poster.

The answer was announced at the press conference, and it was actually talking about 5G.

This year, 4 iPhone 12 models support 5G, which is not too surprising. More people are curious about whether Apple will use 5G baseband chips from Qualcomm on the iPhone 12 after the relationship between Apple and Qualcomm returns to normal.

This is very likely. After all, Intel’s baseband business has been sold to Apple, and at this stage, Qualcomm can be said to be Apple’s best and only supplier choice.

Another detail that 5G needs to pay attention to is the frequency band. According to the data given by the official website, the iPhone 12 currently sold in mainland China has comprehensive support for the 5G frequency band, basically covering all 5G frequency bands of the three major operators of China Mobile, China Unicom and Telecom, even China Radio and Television, which does not yet have business. The corresponding frequency bands are also supported.

▲ On the side of the US iPhone, you will see an elliptical antenna area. This is specifically designed for millimeter waves, and iPhones in other regions will not have it.

As for the millimeter wave version exclusive to the US version, you will see that the iPhone 12 sold in the region has an additional antenna area on the side, which is prepared for millimeter waves.

However, since it will take some time for domestic commercial millimeter wave to be used, you can rest assured to choose models from the National Bank, Hong Kong version and other regions, instead of deliberately choosing the US version.

It’s a pity that there is no high brush, but it is also important to ensure battery life

When will iPhone be able to use the same 90, 120Hz high refresh rate screens as Android flagship phones, it has been a question of debate for more than half a year.

But as everyone knows, the iPhone 12 does not use a high refresh screen. Although I regret it, I also understand Apple’s choice.

Don’t forget, this year’s iPhone 12 is also Apple’s first batch of 5G iPhones. How to achieve a balance between power consumption and battery life is Apple’s priority.

From the results, the battery life of the iPhone 12 is generally satisfactory, especially when it supports 5G, the battery life data can basically be maintained at the same level as the previous generation.

The first is the iPhone 12 Pro Max. The three data are consistent with the 11 Pro Max. Anyone who has used it should know how good the battery life of the 11 Pro Max last year.

Next is the iPhone 12 Pro. The video playback time is 1 hour lower than that of the 11 Pro. The other two indicators are the same. The estimated battery life is equivalent to that of the 11 Pro.

iPhone 12, the three data are the same as iPhone 11, and the battery life has not changed much.

But the situation of iPhone 12 mini is more complicated. The overall battery life is probably between the second generation of iPhone SE and iPhone 12.

The problem is that the battery life of the second-generation iPhone SE is the worst in the current iPhone camp, and it is generally lower than the battery life of mainstream Android flagship phones.

Considering that the 12 mini is the smallest of the 4 models, the battery capacity is definitely the smallest, so I don’t have much hope for its battery life. The actual performance is still waiting for the real machine test afterwards.​

about the price

Finally, let’s talk about the pricing of iPhone 12. Of the 4 models, the 12 Pro series maintains the same starting price of US$999 as last year, but since the starting capacity has changed from 64GB to 128GB, it can be regarded as an “increased volume without price increase”.

But the main force of shipment is still on the iPhone 12 and 12 mini. At present, these two models can be regarded as “price increase”. Last year, the price of the 64GB version of the iPhone 11 National Bank was 5499 yuan, which corresponds to this year, but it has become the starting price of the iPhone 12 mini.

The iPhone 12’s own starting price has become 6,299 yuan, which means that the price of this standard version without the Pro suffix has increased by about 800 yuan.

The reason for Apple’s price increase is that in addition to better components and new designs, this year also has 5G and screen improvements. It should also want to make room for the more “low-end” 12 mini.

From my personal point of view, iPhone 12 is still the most suitable model for most people. After all, its battery life is not as bad as the 12 mini, the size is appropriate, and compared to the iPhone XR and 11 of the previous two years, this time the 12 is also the screen part of the Pro version; and I like the large screen, and hope to enjoy the iPhone Users who are the best to take pictures can still consider the iPhone 12 Pro series.

So, do you want to buy this year’s new iPhone as soon as possible? I said it doesn’t count, maybe wait a while, Pinduoduo will help you answer this question.
