Cheap and large bowl of 100 million pixels, evaluated by Redmi Note 9 Pro
Cheap and large bowl of 100 million pixels, evaluated by Redmi Note 9 Pro

The Redmi Note 9 Pro released on November 26 brought out a 100 million pixel Samsung HM2 sensor, the first domestic Snapdragon 750G (in fact, the first overseas one is also from Redmi), a Z-axis linear motor, dual speakers, and a 33W fast charge. All these, 1599 yuan can be given to you.

Just like in the south of subtropical climate, in the bloody winter gale, I saw that there was a barbecue shop on the corner of the street that I had never been to. Sit down and order a bowl of ecstatic rice (barbecued rice). When it is brought to you, you instinctively sigh: cheap and big bowl.

Packaging and accessories

Kraft paper plus various cartoon graffiti, as well as a bunch of Kino (mascot) stickers, are very good for my cool taste of the post-00s.

Charging head, silicone shell, factory film, everything, except for environmental protection, all very good.

The charging head is the ancestral MDY-11-EX of Redmi, which is basically the same as the 33W.


This one in our hand is Redmi Note 9 Pro Lake Autumn 8+256 Emperor Edition. The AG glass back cover is blue and pink (orange?), which is the most coquettish of the three color combinations. The camera is "cut edge Oreo", and the middle part is relatively fierce. To some extent, it is the thin LCD screen that has to be blamed.


From the middle frame without breakpoints and slots, you can know the surface material (the metal in the card slot can still be seen). In addition to the card slot and key area, the middle frame has a brushed matte effect, which is provided by N parallel thin wire slots (the same is true for Redmi 10X series).

Redmi Note 9 Pro has a rare infrared transmitter ("bottom cushion"), an extremely advanced 3.5mm earphone port, and the destination of the Olympic spirit. The keys are slightly empty, in addition, the workmanship is solid and fits perfectly.


The long row of earphones is part of the dual speakers, and there is even an "extremely advanced" status indicator light inside.

Note 9 Pro was released a few months earlier than next year's big wave of "middle punch screen phones", and the location of the punch is an age logo: "Have you seen that this is the middle punch, not the punch in the upper left corner in 2020, nor the drip screen in 2019".

The "middle punch" screen is symmetrical and aesthetic. It is more comfortable to watch the video than the "right punch" screen. Playing games will not block some buttons like the "left punch" screen. But in the middle of the notice bar, when you light the screen, you always stare at it carelessly.


Redmi K30 Ultra, Redmi Note 9 Pro and Redmi 10X Pro


Redmi K30 Ultra, Redmi Note 9 Pro and Redmi 10X Pro

The border control of the Redmi Note 9 Pro is between the Redmi K30 Ultra and the Redmi 10X Pro, which has made great progress.

  • feel: The plastic washer on the screen edge is higher, slightly lower than the 2.5D radian of the screen edge. 76.8mm wide, combined with 215g weight, it will not cut the hand, but the hand feel is very "plump";

  • Side fingerprint: Tap to unlock (better effect after removing system animation). One thing to say is that before the fingerprint appears on the half screen, the physical fingerprint is more comfortable, which is more suitable for me, an old man born in the early 1990s. After entering the index fingers of both hands, put the unlocking experience on the desktop, and open the fingerprint under the screen to aim after blasting;

  • Z-axis linear motor : The tuning of the puzzle, comparable to Sony, will make you suspect that this is a rotor motor. The motor vibrates slightly and drags. I hope OTA can rescue it;

  • Dual speakers: It is also a rare configuration of a thousand yuan machine. I like it. Outreach performance, feeling equal to K30 Ultra, weaker than K30 Pro.


Screen and performance

6.67 inch central perforated LCD, five generation gorilla, 120Hz refresh rate, 6-gear refresh rate, 240Hz touch sampling rate. The setting can only be switched between 60Hz and 120Hz, and other gears are automatically controlled by the system.

  • Variable refresh rate: Developer option - Power consumption monitoring - Frame Rate Monitor Tools (MIUI ancestral, other systems don't need to look at it). After you open it, you can observe the screen refresh rate and frame rate. In different video applications, it can automatically become 50Hz | 50fps or 60Hz | 60fps. Once operated, it will soar to 120Hz. The first 10 seconds of the still picture is 120Hz | as low as 1fps. After 10 seconds, 50Hz | 1fps. The e-book users are ecstatic.

  • The measured manual full white maximum brightness is 399 nits, and the edge four corner brightness is 362/368/375/371 nits, with average uniformity. Although it is an LCD screen, it has excitation brightness, with a maximum of 479 nits, which will be sufficient in the big sun.

  • The screen emits color, the primary color is slightly red, and the appearance is OK. There must also be LCD shadowing, which can be seen with the naked eye and the 90Hz A screen.

  • But, however, LCD will never be a slave!!! The 1080P LCD is a full blood 1080P, and the fineness of all AMOLED screens below 2K is completely exploded. The display font is horizontal and vertical, extremely clear, comfortable~comfortable~.

In terms of performance, Redmi Note 9 Pro is Snapdragon 750G+UFS 2.2. The positioning and GPU performance can be known from the second serial number of Qualcomm's works of Zhen · Toothpaste Factory.

Snapdragon 750G, Samsung 8nm LPP process, CPU part is 2 * 2.2GHz Kryo 570 Gold (class A77)+6 * 1.8GHz Kryo 570 Silver (class A55), GPU part is Adreno 619@800MHz

Compare OPPO Reno3 Pro of Snapdragon 765G, Redmi 10X Pro of Tianji 820, Redmi K30 Ultra of Tianji 1000+and Xiaomi 10 Ultra of Snapdragon 865.


CPU operation performance test

Because there are two large cores of 2.2GHz A77 like architecture, the single core has a good performance, and even is "50% open" with Tianji 820. However, the remaining six are 1.8GHz class A55, and the multi-core performance can beat the Snapdragon 765G. However, compared with the Tianji 820 with its own "four 2.6GHz high-frequency A76", there is still one Snapdragon 765G away.


GPU graphics performance test

The GPU part is the essence of the "Qualcomm Knife", and there are few leapfrog bugs. Every SoC is properly arranged. The 750G GPU of Snapdragon is slightly weaker than the 765G GPU of Snapdragon, and Tianji 820 has thrown off several streets.


Flash memory read/write performance test (the K30 Ultra here is 512GB, the Reno3 Pro is 128GB, and the rest are 256GB)

UFS 2.2 is good, and the continuous reading and writing of Redmi Note 9 Pro are all up to the ceiling. Random writing is higher than Xiaomi 10 Ultra and K30 Ultra.

The performance tuning of Redmi Note 9 Pro is extremely advanced. Although the GPU performance is not strong, its output is large and stable (which also leads to high power consumption of its games). The default of Peace Elite is only 40 frames in HD, which is enough to cope with. After 60 frames of HDR HD were turned on in "detour" mode, frame dropping began to occur to a certain extent 10 minutes later, and there were about 58 frames on average 15 minutes later, which is worthy of your run score.

Daily use fluency: Just don't remove animation like me. Redmi Note 9 Pro can make MIUI 12 run smoothly most of the time, even more smoothly than the early Redmi K30 Ultra. For a SoC whose CPU is only a small victory over Snapdragon 765G, the smoothness of Redmi Note 9 Pro has been unexpected.

Redmi Note 9 Pro came out with the latest 100 million pixel sensor Samsung S5KHM2. Find Xiaomi 10 Pro and Nut R2 as the representatives of the domestic flagship of 100 million pixels, while the Redmi K30 Ultra equipped with IMX682 (64 million pixels) is responsible for accompanying the guests.

The Samsung S5KHM2 carried by Redmi Note 9 Pro is the direct descendant of S5KHM1 (Samsung S20 Ultra and Note20 Ultra), with unit pixel ranging from 0.8 μ M reduced to 0.7 μ m. However, there are dual native ISO. 108 million pixels are also "9 in 1 pixels", and 12 million pixels are output in daily use. The 7P lens with the aperture of F1.75 is qualified, but unfortunately it does not have optical anti shake.

The S5KHM2 has a hardware conversion layer, which reduces the processing pressure of ISPs. Except for a few scenes such as the 100 million pixel mode, the actual photo taking experience of Redmi Note 9 Pro is not different from that of ordinary mobile phones.

Someone may ask, "What's the use of a 100 million pixel sensor when it is used as a 12 million pixel sensor?" In fact, the main use of 100 million pixels is to be used as a telephoto lens, except for group photos, landscapes and other scenes that require gross performance (manually open the 100 million pixel mode). Because of its high pixels, Redmi Note 9 Pro can directly omit twice the long focus sub camera like S20 Ultra and Note20 Ultra.

It should be noted that Redmi Note 9 Pro is the flagship and sub flagship this time. Xiaomi 10 Pro and Nut R2 still have optical anti shake S5KHMX. As long as we don't lose sight of it, the 1599 yuan Redmi Note 9 Pro is already successful.

Comparison between subphoto and 100 million pixel mode

Ultra wide angle sample size comparison

In terms of ultra wide angle, both K30 Ultra and Nut R2 are 12 million pixels, Xiaomi 10 Pro is 20 million pixels, and Redmi Note 9 Pro is 8 million pixels. The actual size difference of the samples is very obvious.



Ultra wide angle proof sheet, central magnification

The 120 degree field of vision of Redmi Note 9 Pro is enough. With a very heavy sharpening algorithm, the analytical power of Redmi Note 9 Pro can match the super wide angle of K30U and Nut R2. Emmmm, u1s1, mobile phone manufacturers really don't pay attention to ultra wide angle.



Nut R2 here is a 3x optical zoom, Xiaomi 10 Pro is a 3.7x optical zoom, and K30 Ultra and Redmi Note 9 Pro are both main digital cutting.

However, the 100 million pixel Redmi Note 9 Pro is careless, and the 2x digital zoom may not be adjusted properly, losing to the K30 Ultra (64 million pixels). However, from the 100 million pixel sample below, the ultimate discrimination of the Redmi Note 9 Pro is above the K30 Ultra.


Redmi Note 9 Pro automatic mode vs. 100 million pixel mode

The Xiaomi 10 Pro and K30 Ultra must be in the professional mode to open the 100 million pixel mode and 6400W mode (the white balance, noise reduction and dynamic range of the manual mode will suffer). The Redmi Note 9 Pro, whether professional or automatic, has an imaging style of 100 million pixels and no obvious difference from the actual discrimination. It is the default mode, which is highly available.

High pixel mode contrast, central amplification

In the 100 million pixel mode of Redmi Note 9 Pro, the picture detail is not as good as that of Xiaomi 10 Pro, but it can be compared with that of Nut R2. For the K30U with 64 million pixels, the noise is somewhat unrestrained, and the pixels are not enough. The floors of the building are painted as "backspace".

Xiaomi 10 Pro and Nut R2 are 25 million pixels by default, K30U is 16 million pixels by default, and Redmi Note 9 Pro with 12 million pixels will suffer from poor discrimination. But in the end, it was found that, except for Xiaomi 10 Pro, several machines seemed unable to open the gap.

Summary

According to the current firmware ranking, the Xiaomi 10 Pro is obviously better than the other three machines, followed by Nut R2, K30U and Redmi Note 9 Pro.

K30 Ultra: The Redmi Note 9 Pro, which is slightly better than the 1200W pixel in discrimination, is a bit noisy, sharp, and generally tolerant. In many cases, it cannot be compared with the 1200W pixel Redmi Note 9 Pro. The main problem is that the white balance tends to be magenta, and most scenes are the ones with the most white balance. The photo taking experience is OK. Although there is no optical anti shake, the film rate is high. Weak light scene and even night scene mode respond quickly (after all, there is no prompt of "image quality optimization, please hold your phone"). In Xiaomi mobile phones, this prompt is a "privilege" only available for the main camera models, while Redmi Note 9 Pro also has this prompt.

Redmi Note 9 Pro: Some said and some did not meet expectations. Although it is 0.7 μ m. But after all, it is 1/1.52 inch CMOS, and also has dual native ISO, which is obviously stronger than the IMX682 of K30 Ultra (but I don't know whether it is HM2 or Snapdragon 750G, and Redmi Note 9 Pro does not support it either 4K@60FPS The video is really sad). At present, the performance of the firmware of Redmi Note 9 Pro can not be separated from the K30 Ultra, and the dynamic range is OK, but many scenes will lose the power of discrimination, and the film rate of weak light scenes is low. But after all, it is a new machine, and the hardware strength is there. After a few waves of OTA, it should be possible to get rid of the K30 Ultra, but at this stage, it is still a "potential stock".

Endurance and charging

Redmi Note 9 Pro battery 4820mAh, after 30 minutes of medium game (NBA 2K15), 30 minutes of local video playback, 30 minutes of wifi and 5G surfing respectively. After a total of 2 hours of endurance test, the remaining power is 81%.

At first glance, the overall result is not good, but in fact, except for the game part, video and Internet surfing are very power saving. The game has a high power consumption due to aggressive tuning and weak GPU performance. However, this LCD screen with variable refresh rate has excellent effect, which is very suitable for surfing the Internet, where there are many still pictures.


The Redmi Note 9 Pro is a 33W fast charge, which is a rare high-power fast charge in a thousand yuan machine. From the perspective of the flagship, its power is not high, but its output is extremely stable:

  • The maximum charging power is about 27.4W, which can last for 14 minutes

  • The second stage is 23W-25W, which can last for 36 minutes (charging for 41 minutes at this time), very firm

  • Then the current steps down, and the process lasts for 15 minutes (at this time, the charge lasts for 56 minutes)

  • The last one is 7V trickle for about 10 minutes

  • Fully charged in 1 hour and 7 minutes

This is a "full" minute faster than the Redmi K30 Ultra (4500mAh, 33W), and slightly slower than the vivo X50 Pro+(4350mAh, 44W), which lasts for one hour and three minutes. I am satisfied with the thousand yuan machine.

summary

What can the 1599 yuan Redmi Note 9 Pro give you?

  • AG glass and saucy color matching;

  • Although it has not been adjusted well, it has great potential. It is suitable for a 100 million pixel camera with a strength of 3000 yuan;

  • 120Hz with variable refresh rate, power saving, full blood 1080P+, "no slave" LCD screen;

  • Dual speakers, linear motors, NFC, 33W fast charging, front and rear light sensors, extremely advanced headphone holes and infrared transmitters, etc., a large number of perfect peripheral configurations.

Its short board is the Snapdragon 750G. The thousand yuan machine is a group of equipment that is very sensitive to performance. For them, there has never been a theory of "excess performance". No matter how much performance Qualcomm and MediaTek give, domestic apps like WeChat and Taobao can eat. What's more, Qualcomm has been squeezing toothpaste for two years.

The performance of Snapdragon 750G is now lower in the middle end. Now there is no problem with the smoothness, but this year there will be MediaTek Tianji 820/Tianji 800, next year there will be the flagship performance Exynos 1080 and the 6nm SoC that MediaTek has not yet released. Now it is stuck in the node where the toothpaste tube needs to "open the bottle and release the gate".

To make matters worse, the current matching Redmi 10X 5G, Tianji 8201399 yuan. Of course, compared with the Redmi Note 9 Pro, the screen of the Redmi 10X needs to blink to fill the frame, use faith to interpolate the camera, and use love to provide additional 10.5W charging power.


Redmi Note 9 Pro is a cheap and large bowl of ecstatic food (barbecued rice), but it has not reached the point where some media teachers say "close your eyes and choose". Redmi's superior product line is to blame. If you can buy it, you can add 300 to the K30 Ultra. If you care more about performance and smoothness in a year or two, you should close your eyes and choose Redmi 10X 5G. Redmi Note 9 Pro is reserved for users who "have certain needs for photography, or do not know what their needs are, but have low game and performance requirements".
