[IT House Evaluation Room]Xiaomi 12S Ultra Full Experience: Video Camera King, here? Lai. – IT House

Since the release of the Xiaomi Mi 12 series at the end of last year, the ultra-large cup “Ultra” has become one of the most anticipated mobile phones for the author this year. After all, the previous two generations of Xiaomi Mi 10 Ultra and 11 Ultra have proved to us that Xiaomi is in the field of mobile imaging. “To the top”, so the next new Ultra is naturally worth looking forward to.

Unexpectedly, this wait is more than half a year. Before the Xiaomi Mi 12 Ultra, we ushered in the Xiaomi Mi 12S Ultra equipped with the new Snapdragon 8+ and added by Leica.

After a period of experience with IT Home, I am afraid that this product cannot be simply described as “the king of stacking materials”.

So what is the experience of this Xiaomi Mi 12S Ultra? Is the new Snapdragon 8+ fever down? Is the rice-flavored Leica “poisonous”? Is it worth the wait for half a year? With these doubts in mind, let’s enter the evaluation link.

Part 1: Appearance Design

Like the previous two Ultras, the design of the Mi 12 Ultra is also unforgettable, such as the huge and raised circular image module on the back, when you hold it in your hand, for a moment, it is more like holding a computer that can be used for shooting. phone camera.

In terms of process design, this time, the Xiaomi Mi 12S Ultra did not use ceramics, but used ceramics for the first time.Environmentally friendly silicone skin materialwith a calfskin texture on the surface.

According to official information, this environmentally friendly silicone leather material is often used in high-end yacht interiors, etc. Compared with traditional plain leather, it has a softer hand and a skin-friendly texture, and has better functionality. Anti-aging and anti-dirt properties.

Another obvious benefit of using a plain leather body for the Xiaomi Mi 12S Ultra is thatThe “weight loss” of the whole machineThe weight of the Mi 12S Ultra reaches 225g, and the size of the whole machine is 163.17×74.92×9.06mm. Compared with the previous generation, the weight is reduced by 9g, and it does not have the exaggerated “top-heavy” problem of the previous generation.

Let’s take a look at the detailed design. The entire image module of the Xiaomi Mi 12S Ultra is raised, and there is a circle of 23K gold decoration outside the module.

Beneath the circular module is a matte black back panel that occupies almost one-third of the body area on the back. On the back panel, there is no rumored Leica Cola logo, but a white LEICA logo.

It can be seen that the Xiaomi Mi 12S Ultra has kept the design as much as possible.restraintBut after all, there is a full one-inch CMOS inside the phone, and two half-sized “586”. How to put these three cameras into the circular module in a friendly and harmonious way? It is the science and art of the internal stacking design. The Xiaomi 12S Ultra (from the author’s personal subjective point of view) is quite excellent. Although the camera is seriously raised, it is not particularly obtrusive, and the square has a circle. The design neutralizes this abruptness.

Judging from Xiaomi’s three-generation Ultra product form, it seems thatNot much design continuation, Of course, this is understandable, after all, no one stipulates that high-end design must have a continuation. but,Xiaomi Mi 12S Ultra has indeed achieved the so-called “differentiation” in the design of high-end flagship machineswhether you appreciate this design or not, but I believe that as long as you take a look at the Xiaomi Mi 12S Ultra, you will “never forget its appearance”.

In terms of detailed design, the metal middle frame of the same color as the fuselage has openings such as speakers and SIM card slots at the bottom:

There are also speaker openings at the top, and the dual speakers have Harman Kardon blessings, as well as infrared sensors:

In terms of accessories, including water shell, card removal needle, 67W fast charging head and 6A data cable, unfortunately, the fast charging head is not on the C port. In addition, as a flagship machine, the Mi 12S Ultra also has the necessary configurations such as IP68 and X-axis linear motor.

Going back to the front, Xiaomi Mi 12S Ultra is equipped with a 6.73-inch Samsung AMOLED LTPO screen, using E5 luminescent material, supporting native 10bit color depth, and has a resolution of 3200×1440, reaching 2K level.

Other aspects include 1500nit peak brightness, 1000nit full screen brightness, and P3 color space, JNCD≈0.34, △ E≈0.33, support 1-120Hz dynamic refresh rate, Dolby Vision, HDR10+, HDR10, HLG, and front and rear light environment sensors, etc. .

In general, this pieceThe screen is also fullit is almost impossible to pick out any faults.

Part II: Video Experience

Let’s talk about the hardware first. The main camera of the Xiaomi Mi 12S Ultra is a one-inch-sized custom Sony IMX989 image sensor, which is also Sony’s largest mobile phone camera sensor to date.

It should be emphasized that this Sony IMX989, without any cropping, isThe real deal, the full inch.

How big is an inch, just look at the flagship-level CMOS comparison below and you’ll know:

In addition to the outsole, this main camera is also supported by an 8P aspherical high lens, as well as technologies such as full ink coating, anti-glare coating, cycloolefin lenses, IR filters, and more.

The other two are the familiar 48-megapixel IMX586, which are used for ultra-wide-angle (macro) with 13mm equivalent focal length and 5X periscope with 120mm equivalent focal length. IMX586 is an old friend of Xiaomi, used in ultra-wide-angle and periscope It is the ceiling level of the current industry.

(If you can plug in another 2X portrait lens, it will really take off….)

After talking about the hardware, let’s take a look at the “software” part, which is the much-anticipated Leica.

First of all, in terms of image style, Xiaomi Mi 12S Ultra provides two Leica dual-image quality styles- Leica Classic, Leica Vivid.

Among them, Leica Classic is more inclined to what the human eye can see, pursuing a relatively three-dimensional tone, and the picture has high contrast, which is what we call “German flavor”; while Leica is vivid, the picture is brighter, and the color is relatively bright, The atmosphere is stronger, similar to the effect of turning on AI color enhancement.

On the camera interface, Xiaomi provides these two styles, which can be switched at will according to different scenes.

Let’s take a look at the sample directly:

Leica Vivid, Leica Classic (main shot)

Leica Vivid, Leica Classic (main shot)

Leica Vivid, Leica Classic (5X periscope telephoto)

Leica Vivid, Leica Classic (main night shot)

Looking at the above sets of proofs,The Leica’s vivid saturation is slightly higher, which is ideal for shooting scenes with flowers and flowers and rich colors.; The most obvious feature of Leica Classic is that the dark part is slightly underexposed, and the overall brightness of the picture is slightly lower, which is more realistic and suitable for shooting some architectural, cultural and other scenes.

It is worth mentioning that the German flavor of Xiaomi’s “Leica Classic”,It’s not the same as the German taste of friendsin contrast, the contrast ratio of friends is higher, the contrast between light and shadow is stronger, and the overall dynamic range of Xiaomi Mi 12S Ultra is higher.

In addition to the Leica dual-image quality style, Xiaomi Mi 12S Ultra also brings the same filters for four Leica cameras: Leica Vivid, Leica Natural, Leica Monochrome, and Leica Monochrome HC, as well as three master lens packs, including : 35mm classic black and white lens, 50mm classic rotary focus lens, 90mm classic soft focus lens.

Leica filter proofs:

Leica Vivid, Leica Natural (shot at 5X)

Leica’s bright German flavor is stronger; while Leica’s natural color is a little lighter, but more inclined to the human eye

Leica Monochrome, Leica Monochrome HC (main camera shot)

Both of the Leica Monochromatic filters have high contrast, and the Leica Monochromatic HC also adds “graininess” to further enhance the advanced sense of the proofs

Leica Master Lens Samples:

50mm Classic Rotary Focal Lens

The light spot at the out-of-focus edge is elliptical and rotated inward, somewhat similar to the Zeiss Biotar lens

35mm classic black and white lens

The style is not enough, black and white come together, this 35mm classic black and white lens is more suitable for humanities and street photography

90mm Classic Soft Focus Lens

This lens has a strong sense of ambience, showing a hazy, soft effect as a whole

After talking about the Leica filter, let’s take a look at the performance of the Xiaomi Mi 12S Ultra sample:

First of all, let’s talk about the main camera. The hardware advantages brought by the outsole are quite obvious:Better signal-to-noise ratio, higher dynamic range, superior light sensitivity. For example, in extremely harsh night conditions,This main camera can even be used as a night vision goggleas long as there is a little light source around,The main camera can shoot the effect of “daytime”It is not an exaggeration at all, and the filming rate is quite high.

Another exampleNo need for HDR in many scenarios Now, even in some scenes with high light ratio, the dynamic range performance of the shot proofs can still be comparable to the HDR proofs without HDR turned on.

HDR On, HDR Off

As shown in the picture above, HDR is turned on and off, and there is almost no difference in the proofs

Outsole mobile phones will inevitably cause coma problems (the edges of the subject are blurred). The solution given by Xiaomi Mi 12S Ultra is that when the main camera is shooting at close range, it will automatically switch to ultra-wide-angle and use macro shooting. The coma aberration caused by outsole shooting is avoided, but if this option can be given to the user, it seems that the experience will be better.

Let’s talk about this 48-megapixel periscope telephoto. Under good light conditions, it has excellent sharpness and resolution performance. Even if the 5X and 10X light change proofs are partially enlarged, the details are still sharp and clear. , which is excellent. Similarly, the 5X periscope telephoto has a natural compositional advantage, and the filming rate is very high.

The ultra-wide-angle performance is the same as the first echelon, andThis ultra-wide-angle position is placed in the center of the module(Tips: The one-inch outsole main camera of the Xiaomi Mi 12S Ultra is located on the far left), so as to avoid the problem of finger occlusion as much as possible.

In general, the image stacking of Xiaomi Mi 12S Ultra can be said to have reached a new height, especially the one-inch-sized main camera, which is the first to push the mobile phone camera into the one-inch era (a real one-inch).

On the other hand, it is the blessing of Leica, such as color control, tone, and even the imaging style of Xiaomi mobile phones in the future.There will be a clear and fixed direction, allowing Xiaomi to have its own style and tonewhich is a huge help for Xiaomi in image exploration.

As for the lack of experience, I will briefly talk about it here, such as the master portrait filter,After shooting, there will be an obvious algorithm loading processabout 3s, although it does not affect the final imaging effect, it slightly affects the experience; secondly,Color consistency between main and ultra-wide, and there is room for optimization and improvement. (But in other respects, this ultra-wide-angle is still very strong); thirdly, 5X shooting,Whether the periscope inspires logic is a bit of a mysterythere is no problem in shooting more than ten meters away, but when shooting some scenes a few meters away (especially when there are obstacles in front of the object to be photographed), it is easy to hesitate between the main camera 5X zoom and the 5X periscope, which slightly affects the experience.

Part 3: Performance Experience

In the configuration part, Xiaomi Mi 12S Ultra is equipped with the first-generation Snapdragon 8 + mobile platform, with LPDDR5 full blood version + UFS3.1 FBO refreshed storage, supports WiFi 6 enhanced version, and the cooling part adopts the leaf pulse cold pump cooling system.

In addition, it also includes a 4860mAh battery that supports 67W wired fast charging, 50W wireless fast charging and 10W reverse charging. It also has Surging P1 fast charging chip and Surging G1 battery management chip blessing.

Regarding the first-generation Snapdragon 8+ mobile platform, here is a key point to explain. Compared with the previous generation of products, its biggest highlight is the use ofTSMC 4nm Among them, the super core is increased from 3.0GHz to 3.2GHz, and the CPU performance is also increased by 10%. In addition, although the GPU is still the same Adreno730, the GPU performance is also increased by 10%.

Thanks to the TSMC process, the performance and power consumption of the Qualcomm Snapdragon 8+ Gen1 chip have been greatly improved compared to the previous generation. According to official data, the premise power consumption under the same performance is reduced by 33%, and the GPU also Reduced by 30%.

Let’s take a look at the benchmarks directly:

As shown in FIG,Xiaomi Mi 12S Ultra AnTuTu overall score is 1070459 pointsAs a comparison, the previous generation of Snapdragon 8, some models under appropriate conditions, can achieve a score of 100 points, it seems that the theoretical performance of the first generation of Snapdragon 8 + has indeed improved to a certain extent.

In the flash memory performance test, the write speed reached 1810MB/s, which can be regarded as the top level of UFS3.1.

In terms of GeekBench 5 running points, the Xiaomi Mi 12S Ultra scored 1300 points for single-core and 4170 points for multi-core, and the multi-core score far exceeded that of the Snapdragon 8 model.

(The performance adjustment of different models is different, the above running points are for reference only)

Let’s take a look at the game performance of Xiaomi Mi 12S Ultra:

The test game is “Genshin Impact”, the highest quality of the game is turned on, the performance mode is turned on on the mobile phone, the test time is 30 minutes, the test environment is an indoor air-conditioned room at about 25°C, and the game test scene is wild running + fighting monsters, battle scenes It accounts for more than 40% of the total game time.

(Yuanshen picture quality settings are as above)

As shown in the picture below, the highest quality “Genshin Impact”, 30 minutes,The average frame rate of Mi 12S Ultra is 58.4fpsthe frame stability index is only 2.4 (the lower the better, the general game class < 8):

From the perspective of frame rate fluctuations, there are very few frame drops visible to the naked eye throughout the whole process. In the battle scene, the frame rate is basically maintained at around 55fps, and the running map is maintained at around 60fps.

The power consumption is 5.517W, and the frame energy consumption is 99.5mW.In terms of temperature, the highest temperature measured on the front is 44.5°C Left and right, the maximum temperature on the back is 43.5°C:

From the author’s subjective experience point of view:

first,Compared with the Snapdragon 8 model, the visible frame drop of the Xiaomi Mi 12S Ultra is significantly reduced, the overall game experience is quite stable. Secondly, fever exists, but compared with the Snapdragon 8 model, the Snapdragon 8+ has a slight fever reduction. This change,Similar to the induction cooker from 6th to 5th gear.

Next, we will verify the above conclusions of the author by comparing with the Snapdragon 8 and Dimensity 9000 models with the help of specific quantitative data.

First of all, it is compared with two flagship Snapdragon 8 flagships of the same flagship level.

As shown in the figure below, under the same test conditions and environment as possible, the average frame rate (58.4) of the Genshin Impact of Xiaomi Mi 12S Ultra is indeed higher than that of the other two Snapdragon 8 flagships (53.3, 54.5). At the same time, There is also a big gap in the Drop value on the far right (in the red box).

The Drop value is a core indicator that measures performance stability and cannot be ignored. The smaller the Drop value, the less the number of frame drops in a period of time, and it can also directly reflect whether the game is stuck or not.

The Drop value of Xiaomi Mi 12S Ultra is 49, and the other two Snapdragon 8 are 91.4 and 56.2 respectively. This proves that the number of frame drops of Xiaomi Mi 12S Ultra is much lower than that of the other two Snapdragon 8 flagships.

Let’s take a look at the power consumption comparison.The 5.5W of the Mi 12S Ultra is also lower than the 5.9W and 7W of the other two Snapdragon 8 flagships.(Dual cell power consumption * 2):

In terms of frame energy consumption, the Xiaomi Mi 12S Ultra’s 99.5 is also lower than the Snapdragon 8’s 111.4:

Through the previous set of data, it can be proved that the performance and power consumption of the new Snapdragon 8+ have indeed been greatly improved compared to the Snapdragon 8.

Let’s take a look at the comparison with the Dimensity 9000.

First of all, in terms of frame rate, the average frame rate of Xiaomi 12S Ultra’s 58.4 is slightly higher than the 53.6 average frame rate of the Dimensity 9000 model:

In terms of power consumption, the Mi 12S Ultra’s 5.517W is indeed lower than the Dimensity 9000’s 5.896W (2.948*2):

Writing this can also be a simple conclusion –

The new Snapdragon 8+ on the Xiaomi Mi 12S Ultra is indeed much better than the Snapdragon 8.After using TSMC 4nm, the power consumption has indeed been reduced to a certain extent, and the frequency of the large core has been increased, and a certain performance upgrade has also been achieved.; Similarly, compared with the Dimensity 9000, the frame rate of the Snapdragon 8+ has also been greatly improved, and the power consumption has also decreased to a certain extent.

As for the heat issue,As long as the load is high, it will definitely heat up(After all, it is still this big summer), but as far as the current firmware is tested, it is unlikely that the frequency will drop as soon as it heats up.

If you are currently using Snapdragon 8 models, especially those with conservative performance releases, after using the Snapdragon 8+ of Xiaomi 12S Ultra,surpriseThere will definitely be.

Charging performance In terms of charging, Xiaomi Mi 12S Ultra is equipped with a 67W wired fast charge. In the first 3 minutes of the actual measurement, the charging power can reach more than 55W, and the subsequent maintenance is about 40W, 35W, and 30W. In the first 15 minutes, it can be charged to more than 50% and charged to 90W. After %, it enters the “trickle” state of about 15W. It takes about 40 minutes for the UI to display 100%, and it takes 50 minutes to fully charge. Although it is not as good as the 120W of the Xiaomi Mi 12S Pro, 67W is enough for daily use.

For the battery life part, the actual test used by the author as the main machine,The usage time is 9 hours, of which the screen-on time is 4 hours and 38 minutes, and the total power consumption is 87%, which also includes an hour-long high-intensity game of Genshin Impact. From this point of view, the Xiaomi Mi 12S Ultra can meet the author’s needs for a day’s use of the machine, at least, the battery life is not a short board.

Summarize:

It must be a hooligan to talk about the quality of the product without looking at the price. The price of Xiaomi Mi 12S Ultra starts at 5999 yuan. In my opinion,This is still a very sincere and conscientious pricingso the author also believes that the Xiaomi Mi 12S Ultra is still a very worthwhile video flagship (if the price reduction in the later period is not considered).

The Xiaomi Mi 12S Ultra continues the omnipotence of Xiaomi’s “Ultra” product line. In short, it is a flagship mobile phone that is difficult to pick out in terms of hardware and experience.

Of course, apart from “all-powerful”, the author is more willing to talk about the new Snapdragon 8+ chip and Leica blessing of the Xiaomi Mi 12S Ultra. The most obvious advantage brought by the Snapdragon 8+ is that the performance is improved, and the power consumption is also reduced (especially in low-load scenarios). The author released a new signal – Xiaolongxin, which can still return to the throne of the king.

Let’s talk about Leica again. In the past, although the hardware of Xiaomi mobile phones was very strong in terms of imaging, it did not seem to be too specific, or it was a branded, family-based imaging style, or a continuation, but everyone has seen it, and now friends and businessmen are almost all In emphasizing “familialization”, the so-called “memory colors” of various companies are gradually occupying the minds of consumers. In the long run, when it comes to taking pictures and videos of a certain brand, a specific image will naturally emerge in consumers’ minds.

In the author’s observation, the previous Xiaomi seems to lack this advantage. However, after the joint name with Leica, this situation will definitely be broken.After being nurtured by the “hundred-year German taste”, Xiaomi 12S Ultra already has its own color style and tone. As for whether this German taste is “toxic” enough, the author is not a professional photographer and is not qualified to evaluate, but at least, we are also pleased to see that the next direction of Xiaomi Imaging is clear and specific.
