ByBrielle Wilson 2019-05-29 1310

"Unconventional, I really did the flagship." This is my first impression after getting Redmi's first flagship K20 Pro.

As we all know, the flagship machine has always been the highlight of various manufacturers. In recent years, there has been a tendency for the ship to rise, and the high price has gradually become a new pricing standard. This has also made the "flagship machine" gradually unreachable, and can only be seen from afar.

What is the flagship? Redmi, who became an independent sub-brand after leaving Xiaomi, is also thinking about this issue. Just a while ago, the news that Redmi announced its role as a true flagship machine ignited the enthusiasm of the market and became the focus of discussion.

Of course, if you want to be a flagship machine, does this mean that Redmi will also go to a high-priced route, or you have to exchange the parameters for the low-priced route, and everyone will wait and see. And after the official release of heavy news, the voice of "true incense" has also become one after another.

Just this afternoon, the Redmi K20 Pro, the first flagship machine released by Redmi, finally met with you. We also got the 8GB running memory version of this new machine for the first time. Why is it that I made such a sigh at the first time I got the real machine? Today, let's talk about this amazing redmi K20 Pro, the first flagship of Redmi!

Appearance: a smoother feel, more glamorous

All along, the user has a persistent pursuit of the feel of the mobile phone, more textured, more tactile products can capture the user's eyes in the first time.

The moment I got the box, I actually captured our hearts. The outer box of the Redmi K20 Pro is black and red with the outermost color, while the inner layer is made of "Sao" purple color. At the same time, the purple inner box is also printed with a cartoon image - known as "The Big Devil." "The cartoon logo is very individual and has a younger character.

On the appearance of the mobile phone, the Redmi K20 Pro adopts four curved 3D glass to create the fuselage. At the same time, it has a narrow frame, and the curvature of the edge of the fuselage is smooth and smooth. It is very comfortable in the hand, visually and palm. The perfect fit.

In terms of the back cover, the Redmi K20 Pro is equipped with a gradual texture structure. It is said that after a total of 16 complicated processes in 5 steps, a total of nearly 600 million nano-gratings have been carved, and finally such a stunning texture effect can be achieved. What we got in the hand is the glacier blue version. At first glance, it seems that there is a different kind of beauty. The design of the arc is just right, and the grip is extremely comfortable. At present, there is also a red version of the flame and a carbon fiber version that incorporates architectural design concepts.

When it comes to the back cover, we have to talk about the camera. The Redmi K20 Pro adopts a three-shot combination. The camera position is not normally placed on one side, but the center-symmetric design makes the beauty of symmetry perfect and very fashionable.

On the front screen, the Redmi K20 Pro uses a 6.39-inch AMOLED 19.5:9 FHD+ polar screen to support Sunscreen 2.0, allowing the screen to display content by further optimizing contrast and color performance based on the first generation technology. The performance is more realistic in outdoor scenes, and the new smooth transition effect becomes more readable when the highlight mode is activated.

Of course, as the first flagship Redmi K20 Pro of Redmi, this time, the design of the water drop screen or Notch screen was not adopted, but the introduction of a new COF process and a narrower screen module and the reduction of smart antenna switching technology. In the clearance area, the width of the lower frame of the Redmi K20 Pro is only 3.8mm, and the upper frame and left and right margins are reduced to 2.1mm and 1.85mm respectively, which has reached the industry leading level.

Without the Notch screen and the water drop screen, the Redmi K20 Pro uses a lifting design on the front camera. The breathing light strips on both sides of the camera can provide elegant and transparent light effects, and the ring light strip on the top of the front camera also reminds you of daily message reminders and charging status prompts. Users can also choose among 6 preset sound effects. The design of your favorite lifting sound is also extremely in line with the characteristics of younger.

Of course, as the earphone hole that has disappeared on the market, the 3.5mm headphone jack has been able to return to the Redmi K20 Pro. This is also the expectation of many enthusiasts, with Mi Sound self-developing amp sound effects, allowing users to be immersed.

Overall, the Redmi K20 Pro has its own unique features, a smoother feel, and a more glamorous look. In the screen color, Redmi K20 Pro also carried out low-brightness color gamut compensation and grayscale optimization, and with pure hardware DC dimming, directly integrated into the screen driver chip through the millet self-developing algorithm, the color transition effect is better, the perception Better, the display is better.

Taking photos: Photo optimization is better with AI smart scenes

In the photo, the Redmi K20 Pro is a three-shot combination of 48 million main photography + 13 million wide-angle + 8 million telephoto, and the aperture of the three-shot is F1.8/F2.4/F2.4. The main camera uses the Sony IMX586 flagship sensor, which has a 1/2-inch outsole, supports four-in-one 1.6μm large pixels, and also supports 48 million photos straight out through hardware Remosaic pixel rearrangement. With super high resolution.

At the same time, Redmi K20 Pro also introduced a laser hybrid focusing system, which uses phase + laser + contrast multi-mixed focus to optimize scenes such as AI scene recognition, city night scene, and focus capture.

It can be said that as the first flagship Redmi K20 Pro of Redmi is really very good, let's look at the actual proof performance.

The Redmi K20 Pro generally outputs images in a 12 megapixel mode by default to take advantage of IMX's high sensitivity. Through the actual proofs, we can see that the overall photos have vivid colors, both indoors and outdoors. The purity and saturation of the photos are very good, and the details are preserved in the picture. In an indoor environment, the white balance is accurate, the brightest and darkest in the picture can be clearly distinguished, and the highlight suppression is just right.

The Redmi K20 Pro can also support 48 million proofs, although it looks like the 12 million pixels, but if we zoom in on the details, we will find that 48 million pixels are more expressive, less noisy and more detailed. It is also clearer.

Shooting in indoor and outdoor light, Redmi K20 Pro can also automatically recognize the current scene, such as buildings, flowers, white clouds, etc., in order to match the more appropriate parameters to optimize the current scene, so that the performance of the photo becomes more excellent.

Of course, when the Redmi K20 Pro is filming buildings and taking photos with many people, the system will intelligently remind users to switch to the 13 million ultra-wide-angle lens. The super wide-angle mode is used to shoot more than the normal mode, the field of view is wider, and more things are accommodated. More abundant, suitable for shooting scenes, buildings and other big scenes.

When using the Redmi K20 Pro's night scene shooting, the screen did not appear overexposed or underexposed, the light suppression performance was good, the details of the non-illuminating objects were well preserved, and the filming rate was good.

In terms of taking pictures, thanks to the AI ​​scene optimization of the Redmi K20 Pro and its laser hybrid focusing system, the overall performance of the photos is very excellent, and the image quality is greatly improved.

Fingerprint recognition: faster recognition speed

The release of the first flagship Redmi K20 Pro, the use of screen fingerprint recognition technology in the unlocking, to eliminate the back fingerprint opening, so that the overall performance is better, and second, the front of the fingerprint eye control , can have the best operating experience. As the current optimal unlocking method, the recognition speed is very important.

We first enter the fingerprint and then perform multiple unlocking operations. We can find that the fingerprint recognition speed is quite fast, and the recognition process can only be seen in the delayed state. At the same time, even in the state of the screen, there will be a cyan spot, which is convenient for the user to unlock.

In terms of screen fingerprint unlocking, Redmi K20 Pro uses the industry's leading seventh-generation screen fingerprint technology. Its core is a lens-type optical fingerprint module with a single pixel size of 7.2μm compared to the sixth-generation screen fingerprint sensing area. Increased by 100%, finger detection area increased by 15%, signal dynamic range increased by 33%, signal-to-noise ratio increased by 40%, and the unlocking success rate for special scenes such as strong light, dry hand, and low temperature increased by 30%. At the same time, Redmi K20 Pro uses cDSP parallel acceleration to compare fingerprint data, further reducing the average unlock time. It also introduces a gradient fingerprint light. The fingerprint unlocking bright spot can adjust the brightness according to the environment adaptively, and reduce the visual stimulation when using the fingerprint to unlock at night, which is very considerate to the user.

Large-capacity battery, AI smart power saving long battery life

In terms of charging, Redmi K20 Pro has built-in 4000mAh large battery, 27W wired fast charging, and MIUI system's AI intelligent adjustment screen backlight, chain application start control, application power consumption dynamic management and other functions, the use time becomes longer.

In the case where the remaining power is 0, we also measured the fast charge of the Redmi K20 Pro. The result is shown below.

The overall speed of the Redmi K20 Pro averaged slightly, with a slight slowdown in the last ten minutes. 41% of the electricity can be replenished in half an hour, and it takes 85 minutes to fill, and the speed is quite impressive. Users only need to use the piecemeal time to quickly replenish the phone's power and ease the battery life anxiety.

In terms of battery life, the Redmi K20 Pro also uses AI smart power-saving optimization, intelligent management of applications and game power consumption, and avoiding the "rogue" chain application startup resulting in invalid power consumption. At the same time, through the AI scene judgment, under the different use states of WeChat, Weibo, and reading lights, the screen backlight is intelligently adjusted to achieve the purpose of power saving. When you sleep, the phone will automatically enter sleep mode, and the power saving performance will rise.

Unsurprising flagship configuration

As the flagship standard of 2019, in terms of hardware configuration, Redmi K20 Pro is also equipped with the Snapdragon 855 mobile platform without any surprise. As the strongest flagship mobile platform, the Snapdragon 855 is built with 7nm technology, Kryo 485 custom core, new 1+3+4 core design, with Adreno 640 GPU, Hexgon DSP, in computing, graphics, shooting, AI Excellent experience in all aspects of voice, games and more. In general, Qualcomm Xiaolong 855 has reached the highest level of current mobile platforms in all aspects.

In order to exploit the strength of the Qualcomm Snapdragon 855 mobile platform, the Redmi K20 Pro uses an 8-layer graphite stereo cooling system, which is upgraded from the single-channel cooling of the ordinary mobile phone to the upper and lower dual channels. Compared with the single-layer graphite heat sink, the heat dissipation capability of the 8-layer graphite uniform body is increased by 650%, so that the heat generated by the motherboard can be quickly dispersed by the processor to the external space, reducing the temperature rise caused by heat accumulation.

We used Ann Bunny to perform performance points, and the final score was 371,016 points, ranking first, and the real attribute can be flagship. We also carried out the game's actual measurement. In the game set to the highest quality "Peace Elite", after about 15 minutes of game, the thermal imager is used for temperature detection. The maximum temperature of the fuselage is about 40 degrees Celsius. In the upper left corner of the fuselage, the overall performance is still satisfactory.

Of course, the operation of the whole game is very smooth, without the situation of the card, the game experience is excellent. In the optimization of the game, Redmi K20 Pro also implements the new Game Turbo 2.0 game acceleration solution to realize the overall optimization of the touch mechanism under the BSP, to improve the priority of the touch response event and reduce the touch processing time. At the same time, vibration feedback can be given in the game according to the shooting frequency, and the user can enjoy the 4D touch.

Moreover, the program also added a chicken "night vision device" function. When turned on, the Redmi K20 Pro will optimize the contrast of the dark portion of the screen at the bottom, greatly improving the visibility of the screen, and can be active in the battlefield at night.

Additional: Smooth system experience, next-generation NFC solution

The Redmi K20 Pro comes pre-installed with the MIUI system based on Android 9. The UI is still the style of MIUI, and the flat design is more personalized.

In terms of storage, the Redmi K20 Pro is optimized with I/O access and file system by carrying Mi Turbo system-level acceleration scheme, which makes the storage read and write IOPS, the speed is greatly improved, and the file access efficiency is also improved.

At the same time, Mi Turbo has also improved the file storage system, and the flash will be automatically defragmented when it is idle. After finishing, the small file sequential storage space is more compact, the reading efficiency is higher, the large file physical blocks that need to be segmentally stored are more continuous, and the system operation is smoother.

Moreover, the Redmi K20 Pro is the first Redmi product with multi-function NFC, using NXP's next-generation NFC chip SN100T, which increases transaction speed by 30% and supports door card emulation.

Xiaomi Bus also provides benefits for the Beijing-Tianjin-Hebei Intercommunication Card 2019 for free card opening and 11 free card transfer cards. It can be used in 202 cities across the country. The balance of the card can be transferred synchronously with the Xiaomi account. Mi Pay also supports UnionPay's touch and more than 100 applications online payment, adding support for the US Mission Flash Pay and Jingdong Flash Pay, users can enjoy more exclusive offers.

Sum up

The Redmi K20 Pro is the first flagship machine after the Redmi has been removed from Xiaomi. It is a true flagship mobile phone in terms of appearance, photography, battery life and performance. Eclectic, the flagship is the ultimate, so that the "flagship" has become within reach.

With the increasingly fierce competition in the domestic mobile phone market, many mobile phone manufacturers have begun to use the sub-brands to fight the price-performance war. As an independent brand, Redmi adheres to the product values ​​of "holding millet values, adhering to high quality and extremely cost-effective", and has achieved the ultimate in cost performance. The launch of the first flagship Redmi K20 Pro, with its stunning appearance, more innovative technology, and a shrinking flagship configuration, believes that there will be a wave of "true flagship" in the market.
