Xiaomi Mi 12 dual flagships released with luxurious cooling to control the Snapdragon 8 to benchmark the iPhone 13 with speed and feel

The size, price, positioning, and main features of the three models are quite clearly differentiated. There are individual choices for the extreme school, the fashion school, the lightweight school, and the budget school.

The prices of the three models are: 4699 RMB, 3699 RMB and 3199 RMB. The starting price is lower than last year's Xiaomi Mi 11 series.

The international version is on the market, so we will know which models will be released after the international version will be released (if it is customary, there will be). Personally guess... The materials used for this year's Xiaomi Mi 12 Pro should not be as expensive or difficult to mass-produce as the 11 Ultra.

The international version should have the highest-end model... (and there are also international users who like large sizes...)

It was mentioned at the press conference why Xiaomi wanted to be a small-sized flagship, mainly because of the feedback from Mi Fans, hoping to have a flagship with a moderate size, and the second is because there are really few specifications in the Android world except for vertical folding screens. It's a good entry point for a flagship but a decently sized phone. (Now the big mobile phone has to be used on the back)

Directly calling out the iPhone 13 will inevitably lead to a war. B3F-1150 especially clearly mentioned that the Xiaomi Mi 12 Pro just depends on the high-end iPhone 13 Pro Max and does what it does. So you can look at the content of Xiaomi Mi 12 Pro, and then think about whether it is neck and neck or higher? Or are the two fundamentally different?

Appearance: Big screen but easier to handle than i13 ProMax

The Xiaomi Mi 12 Pro screen has a 6.73-inch screen, which is narrower (74.6mm) than the 6.7-inch i13 Pro Max and weighs 205g. The narrower screen is better for a more stable grip, which is really good.

Xiaomi Mi 12 Pro comes in four colors: black, blue, purple, and wild green. The wild green is made of PU, which is a polymer plastic, but has the texture and touch of leather, which should look good visually.

In fact, size and feel are the main features of Xiaomi Mi 12.

The 6.28-inch screen is enough for browsing, and it is not really too small. Then the Xiaomi Mi 12 has a width of 69.9mm and a weight of 180g -ic/" title="180g model">180g-ic/" title= "180g model">180g-ic/" title="180g model">180g-ic/" title="180g model">180g-ic/" title="180g model">180g-ic/" title="180g model">180g-ic/" title="180g model">180g-ic/" title="180g model">180g-ic/" title="180g model">180g-ic/" title="180g model" >180g-ic/" title="180g model">180g-ic/" title="180g model">180g-ic/" title="180g model">180g-ic/" title="180g model">180g -ic/" title="180g model">180g-ic/" title="180g model">180g-ic/" title="180g model">180g-ic/" title="180g model">180g-ic /" title="180g model">180g, it is easier to hold the whole, or put it in the pocket and put the bag without burden.

Screen: Also advertised as Pro Display

The two screens are AMOLED, and both mentioned that they have obtained the certification of DisplayMate A+, for example, they both support primary color display technology, 360-degree light sensitivity, support HDR 10+ and Dolby Vision, and use Corning Gorilla Victus glass...etc. Breaking its 15 test records.

However, the screen of Xiaomi Mi 12 Pro uses E5 material, imported dynamic update rate, LTPO power saving technology, 2K resolution, and peak brightness of 1500nits. These are specs that the Mi 12 screen doesn't have, but it supports 12-bit color depth, peak brightness up to 1100nits, and a maximum refresh rate of 120Hz.

luxury cooling

Both Xiaomi Mi 12 and 12 Pro use the Snapdragon 8 Gen1 platform, and a media test was released last week. According to the results, the CPU performance has not improved as much as expected, but the GPU performance has improved by leaps and bounds, but this improvement is due to the large power consumption, so Still have to do a good job of cooling. As a result, my personal focus is also to see how the Xiaomi Mi 12 dissipates heat.

Basically, they use multi-layer or extra-large graphite, and a larger VC (Vapor Chamber) soaking version.

For example, this is the cooling configuration of Xiaomi Mi 12.

Do these luxurious cooling configurations have any effect?

Xiaomi Mi 12 also provides three power/performance distribution modes: Balanced, Performance and Extreme. It was also announced at the press conference that the Mi 12 Pro test is the most commonly used balance mode for ordinary people, and the daily working temperature is well controlled.

Dynamic performance tuning

In addition to heat dissipation, there is also power consumption to control. Both of them provide Xiaomi's self-developed "dynamic performance scheduling" function. The system will dynamically adjust the screen update rate and CPU three-cluster operating frequency according to the needs of different stages of work, and allocate performance vs. The proportion of power consumption to avoid unnecessary waste.

For example, when the game starts, the focus is on speed, so the screen update rate is reduced, but the super core and large core work at a high frequency to complete quickly.

According to Xiaomi, these adjustments are changed in milliseconds. According to their tests, playing "Glory of the Dead" at 120fps for 30 minutes can reduce power consumption by 20% compared to the Xiaomi Mi 11 Pro. But it did not mention whether the matching program or game should be optimized accordingly to support dynamic adjustment.

High-density batteries enable high capacity in a small size

The previous dynamic screen update rate and dynamic performance adjustment have mentioned the purpose of power saving, but in fact, both of them said that the built-in battery capacity is not very low.

Both models use lithium cobalt oxide batteries with high energy density. The Xiaomi Mi 12 has 4500mAh, which is more than a mobile phone with a similar screen size, and supports 67W wired fast charging, 50W wireless fast charging and 10W reverse charging. However, there is no indication on the specifications whether a 120W charger is included in the package.

The Xiaomi Mi 12 Pro is equipped with a 4600mAh battery, which is not too small. With the charger supported by Xiaomi, it can charge up to 120W fast, which can be fully charged in 18 minutes. In addition, it also supports 50W wireless fast charging and 10W reverse charging.

In order to do 120W fast charging on Xiaomi Mi 12 Pro, Xiaomi put in the self-developed Surging P1 charging chip. It is used to control charging boost, output current, charging safety, avoiding centralized heating, etc., all for efficient and safe charging.

The large amount of power can ensure the endurance of daily work. According to Xiaomi's test, the heavy-use power performance of the two is much better than that of the Xiaomi Mi 11 Ultra.

Xiaomi Mi 12 Pro has 10% power remaining after 5 hours of heavy use.

Sound: Pro supports four-unit speakers

There are speakers on the upper and lower sides of the two Mi 12s, as well as wireless Hi-Res certification, Dolby panoramic sound, and co-tuning with harman/kardon, but the placement of the two speakers is not the same as the composition.

The stereo dual speakers of the Mi 12 are in a symmetrical position, while the Mi 12 Pro is equipped with four units and dual speakers located at the opposite corners.

When Xiong Xiong saw that the Xiaomi Mi 12 Pro was equipped with four-unit speakers, he thought it was four speakers, but when he looked at the specifications, he found that it was still two speakers, but each of the two speakers had a high-frequency and a low-frequency sounding unit. I don't know what it sounds like, but there are high and low bass units, and there are on both sides. It should sound more layered and clearer.

Camera: fast follow focus

The cameras of the two Mi 12s are different, but both have new demands: fast speed, and focus on everything. Of course, there are also new upgrades for night mode and beauty.

The three lenses of Xiaomi Mi 12 Pro are 50 million pixels / f1.9 / OIS main camera, using SONY IMX707 sensor, 1/1.28 inch large, after four in one, it can shoot with a unit pixel of 2.44 microns, an increase of 49%. amount of light. I checked that this sensor supports Dual-PD full-pixel focusing. The other two are a 50-megapixel portrait lens and a 50-megapixel, 14mm-equivalent ultra-wide-angle lens.

QQ图片20211229093824.png

The main camera mainly uses the large-size IMX707, but because there are also 1/1.13 sensor models on the market, 1/1.28 inches is also considered large, but there are days outside.

The Mi 12 is a 50-megapixel/f1.88/OIS main camera, using SONy IMX766, which is a photosensitive element that is also used by many flagship machines. The other two are 13 million pixels, equivalent to 12mm ultra-wide angle, and 5 million pixels, equivalent to 50mm telephoto macro lenses, which can take close-up shots from 3 to 7 cm.

Among them, the acceleration speed includes: fast startup, fast continuous shooting, and fast night shooting.

It is mentioned here that the startup speed is accelerated by 21.2%, which is more conducive to capturing.

The continuous shooting speed is accelerated by 209%, and every time you press it, the frame will not drop, and you can shoot sports themes.

But I noticed that in the test of Xiaomi Play, instead of holding down the shutter for a long time during continuous shooting, you have to click quickly and continuously... If this is the case, then the experience is not very good... In addition, it does not explain that every time I took a few pictures in seconds, and I know if there is an Xperia mobile phone that is faster.

In addition, both of them also emphasize "focusing on everything", which can track eyes, faces, bodies, pets, and moving objects. Xiaomi mentioned that this is from the previously published robot dog CyberDog. The technology of the owner tracking system, the system will detect objects Features and word learning to continuously track and focus, even if a passerby temporarily blocks it, it will not lose focus, or accidentally appear on the scene, as long as it returns to the screen within 3 seconds, it can continue to track. And you can double-click to lock the focus, which can be used when taking pictures and videos.

The flagship phone has had tracking focus for a long time. The tracking focus of Xiaomi Mi 12 seems to be different. It will learn which object is being chased, and then lock and follow. It will also change the tracking target as the person moves back and forth, whether it is the face or the whole body. .

But my question is:

How to move laterally is on the same focus plane, and it is easy to focus without tracking, so the real thing should be whether it can focus when walking back and forth quickly?

The two main lenses are both 24mm, which is actually a bit wide-angle. Maybe the distance beyond the arm does not have a deep depth of field, and the focus difference is not obvious (like pan focus). For video, does the focus tracking help at this time? Might want to see a test shot. And what about the success rate of taking a speed-sensing background-focusing photo?

Whether shooting a moving subject can be successful, the light factor may be more important. Many failures are due to insufficient automatic detection shutter speed, resulting in motion blur. When the Xiaomi Mi 12 is tracking focus, can it also consider the light and moving speed at the same time, while the automatic detection What about the right shutter speed? Or does this mode require manual tuning of parameters?

I don’t know how the experience and success rate of the actual shooting focus tracking are. At present, the tracking focus function of everything is very powerful. Do you need it? Let's wait and see the mainland media test.

But Sony said: You are not targeting the iPhone, you are targeting me!

In addition, the three lenses of Xiaomi Mi 12 Pro can shoot super night scenes and also support night scene video. This effect is unknown but it seems practical.

Did this year's Xiaomi Mi 12 make you surging? Do you think there is a benchmark to the iPhone 13?

No matter whether the function makes you surging, but the Xiaomi Mi 12 series planning seems to be more pragmatic, less emphasis on the black technology that reaches the horizon, but to take care of the hand feel, reduce power consumption, increase battery, optimize signal reception, and heat dissipation. .. Waiting for the fundamentals, it seems to be in line with what Lei Jun said before the publication: this year, we should not only pursue fast, but also be stable and go far (is it?)
