Redmi K30 Pro 5G Review: With Snapdragon 865, 30x Digital Zoom


Redmi K30 Pro 5G has been officially released, and it did not miss the promise of the “true flagship”: it uses a full-screen pop-up solution. The Snapdragon 865 flagship platform, 5G dual-mode, and LPDDR5 memory. This year’s flagship phone does not have standard equipment In the absence, it was also unexpected that “following the above” brought UFS 3.1, which makes UFS 3.0’s Xiaomi 10 series side, and it can be said that this phone does not completely exclude the competition with the Xiaomi brand flagship.

There are two different versions of the Redmi K30 Pro series, one is the K30 Pro and the other is the K30 Pro zoom version. Based on the former, it has enhanced image capabilities. Real flagship. In terms of price, the K30 Pro has achieved 6 + 128GB from 2999 yuan!

Lu Weibing, President of Xiaomi Group China, bluntly stated that the Redmi K30 Pro zoom version has taken up and down the cost of taking photos, and for the first time has OIS optical image stabilization, and directly on two.

Design & Appearance

In this “front window swing hole” era, Redmi K30 Pro is a rare 5G flagship with a true full screen. Since the K20 Pro, the author has been thinking about the true full screen. Although no holes, no bangs, and no water droplets can indeed give users a complete and full-screen visual experience, today, this time period of 5G has brought a certain degree of difficulty to pop-up full-screen, making it in becoming a lonely landscape in 2020.

Taking the Redmi K30 Pro as an example, the number of components is 3885, which is an increase of 268% over the previous generation K20 Pro. The surge in number has made it difficult to arrange the components of the motherboard, which was originally small.

Under the premise of the proliferation of components, front pop-up and rear-centered design pose great challenges to the motherboard design.

Originally, the entire motherboard was divided into two “big pits”, which led to a significant reduction in motherboard utilization.

After the motherboard is divided, the heat dissipation becomes a huge problem. The biggest advantage of the complete motherboard is that the heat dissipation is very uniform. The heat from the central heat source can be easily conducted through the entire motherboard. In the case of two “big pits” It is impossible to center the heat source, and at the same time take into account a large amount of power to ensure the battery life of 5G users.

The Redmi K30 Pro insists on continuing to use the pop-up full screen on the premise of solving the above problems. So is the pop-up front camera durable? The author is not willing to easily drop the evaluation phone in his hand, here is the official effect display. The Redmi K30 Pro’s pop-up design can withstand the test of 300,000 bounces. If you stick to taking 100 photos every day, you can use it for more than 4 years.


Redmi K30 Pro also adopts a middle-frame integrated rail design, spring device physical protection, magnet + Hall calibration chip pressing protection, and also optimizes the spiral stepping motor, making the previous generation 120ms drop protection recovery induction speed increase by 17%, not afraid of accidents fall. In a word, it is durable and not afraid of falling.

The breathing light was originally standard on mobile phones, but the structure of flagship phones is getting more and more complicated, and manufacturers have canceled it by default. The Redmi K30 Pro follows the K20 series pop-up + breathing light design. Different notification scenes display different colors of light effects, such as charging blue light effects and green light effects for incoming calls, to achieve a multi-dimensional reminder effect.

Redmi K30 Pro is available in Sky Blue, Moon Mubai, Space Gray, Star Ring Purple, and these four colors. What we get is Space Gray. The space-colored K30 Pr is much more restrained and low-key than the previous K20 series of flame red and glacial blue styles, even containing a business model.

It is worth mentioning that the K30 Pro is equipped with double-sided Corning Gorilla 5th generation glass, which is 1.5 times more resistant to drop and supports IP53 level splash-proof life. The shell process adopts the same AG process with light and mist to prevent scratches and fingerprints.

The 64MP Sony IMX686 is still quite large. Like most other mainstream models, the lens of the Redmi K30 Pro also has unavoidable bumps. It is recommended to use it daily. The Redmi K30 Pro retains the 3.5mm headphone jack and the infrared remote control. These are the “good traditions” of Redmi Redmi. At the bottom are the USB-C interface and the SIM card slot.

Redmi K30 Pro Cameras

Redmi is inconsistent with the past Redmi and finally began to exert its power in mobile phone imaging capabilities. There are two different versions of the K30 Pro series, the K30 Pro and K30 Pro zoom versions.

1. K30 Pro: 64MP Sony IMX686 + 13MP super wide-angle lens (123 °) + 5MP telephoto macro lens (AF 3-10cm) + 2MP depth of field lens (1.75 μm).

2. Redmi K30 Pro zoom version: 64MP Sony IMX686 OIS optical image stabilization + 13MP ultra-wide-angle lens (123 °) + 8MP 30x zoom lens OIS optical image stabilization + 2MP depth of field lens (1.75 μm). With the addition of dual optical image stabilization and a telephoto lens, it is clear that the zoom version of the image will be even better. It happened that we got the zoom version, so we started from this phone to interpret the image performance of the K30 Pro.

Optical image stabilization

Before putting out proofs, let’s talk about the most obvious upgrade of the K30 Pro zoom version-dual OIS optical image stabilization.

Everyone should have a similar experience, that is, when the light is not good, the mobile phone camera is very easy to take pictures. This is because the light is dark, and the exposure time of the photo will belong. As long as the handshakes slightly, the photo will be empty. To solve this problem, we need to use anti-shake technology. There are two types: optical anti-shake (OIS, O = optical), and electronic anti-shake (EIS, E = electronic).

To be honest, the cost of optical image stabilization is currently quite expensive, and it is rare for a mobile phone to be equipped with two optical image stabilization at the same time.

In addition to the 64MP main camera that needs optical image stabilization, this time the K30 Pro zoom version is also equipped with 3x optical zoom and a 30x digital zoom lens. A little jitter in the telephoto shooting will have a great impact, so the telephoto lens also Equipped with optical image stabilization.

To put it simply, the principle of optical image stabilization is that the subject shakes to the right, and the lens shakes to the left (also in other directions) to offset the shake of the subject. During the entire process, the lens appears to be in a state of “hovering”. The vibration is detected by an acceleration sensor, and a micro motor drives the lens to perform compensation. The result is that you are shaking, but the position of the lens is constant.

We don’t talk much, let’s look at the real proofs.
Day proofs

First look at a set of “bird shots”. It should be noted that the water birds are constantly moving, so the position and movement of the water birds in each photo will change.

Foot 865 flagship price bottom line Redmi K30 Pro zoom version first evaluation: this time the blood.

Does it feel that the 10x digital zoom is not enough? Next, we challenge the limits. Come “fight” a little kite in the sky.

It is worth noting that under 1x shooting, the kite is just a pixel in the sky, and it is difficult to find its track. After stretching to the 30x digital zoom shooting, we can clearly see the appearance of the kite.

Night proofs

At night, the 64MP Sony IMX686 main camera of the Redmi K30 Pro supports four-in-one pixels and 1.6 at night

Even if the lighting conditions are not ideal, the μm large pixel camera can still shoot night scenes with highlights but no exposure and details in dark parts.

In addition, in terms of software functions, the K30 Pro supports Super Night Scene 2.0, which can obtain more dark information through a night scene optimization algorithm based on the RAW domain.

Let ’s take a look through real shots (if you want to highlight an obvious theme, I think it ’s easier to guide the visual attention and create a clean night scene after turning off the watermark).

Redmi K30 Pro Hardware

In 2020, China-US co-produced blockbusters have not blossomed, and the 5G performance flagship phone has fully blossomed.

They all use the Snapdragon 865 5G platform + X55 5G baseband without exception, and the K30 Pro is no exception. Snapdragon 865 is a new generation flagship 5G platform released by Qualcomm in early December last year. It is one of the most powerful 5G platforms in the Android camp.

As for Snapdragon 865, I believe that everyone also knows a lot. This generation has upgraded the A77 large-core CPU, the Adreno 650 GPU with upgradeable drivers, the fifth-generation Qualcomm AI Engine artificial intelligence engine with performance up to 15 TFLOPS, and the Spectra 480 with 4 times the performance. ISPs also support LPDDR5, UFS 3.1 flash memory, Wi-Fi 6, Bluetooth 5.1, etc., and they are almost perfect in almost every aspect.

In addition to the 6 + 128G version, the K30 Pro fully supports many new features such as the above LPDDR5, UFS 3.1 flash memory, Wi-Fi 6, Bluetooth 5.1 and more.

Snapdragon 865 is so powerful, it is no wonder that Lei Jun stated at the Xiaomi 10 conference that “it may be the most powerful 5G flagship processor on the planet”-Lei is always very humble, using the word “possibly”.

Compared with the flagship phone of 2019, this year’s flagship phone no longer focuses on 5G-not to say that 5G is not important, it is actually too important. So these phones all support dual-mode 5G and Wi-Fi 6, everyone agrees on this point, 5G is no longer the only bright spot.

Therefore, in addition to 5G, the 5G flagships of the above-mentioned mainstream mobile phone manufacturers have made great efforts this year in-camera, performance, battery life, and gaming. Each mobile phone has its own one or two tricks.

The K30 Pro still focuses on performance. It has accidentally enhanced the image. Just now we have shown the image performance. The next thing to say is the performance it relies on.

Next, we run a point. However, it should be noted in advance that the K30 Pro system firmware we received was an engineering phone version, and the running software was locked to close the network permission. Therefore, the GFXBench test could not be performed. The final scores of other running software are recommended to be officially listed on the product. The results prevail.

Master Lu

Master Lu can evaluate and compare the five core hardwares of CPU, GPU, RAM, storage, and display. It is more suitable for ordinary white users to understand mobile phone related information.

In Master Lu’s scoring system, Redmi K30 Pro scored over 510,000 points.

GeekBench test

GeekBench profile: A cross-platform CPU performance test tool that accurately reflects the single-core and multi-core performance of the device’s CPU. The test load simulates real-life application design, and the results are more meaningful. It can also measure GPU graphics card computing performance.

The single-core performance can reflect the pros and cons of the CPU architecture design and the level of operation frequency. Multi-core performance can reflect the efficiency of multiple CPU cores working at the same time.

In the GeekBench5 test, the Snapdragon 865 used by the Redmi K30 Pro benefited from the new A77 architecture and achieved very good results in both single-core and multi-core performance tests. The single-core was 17% ahead of the Snapdragon 855 Plus. Leading 18% on multicore.

Compared with the Snapdragon 855 Plus, the top pillar of the Qualcomm camp in 19, the improvement of the Snapdragon 865 on the K30 Pro is more direct on the CPU.

Specifically, the CPU core used by the Snapdragon 865 is the same as the Snapdragon 855 Plus with a 1 + 3 + 4 architecture, with frequencies of 2.84GHz, 2.42Ghz, and 1.80GHz, and the cache capacity has not changed. With the Coterx-A77 architecture, the L3 cache has doubled to 4MB, and the four small cores are still the Cortex-A55 architecture, with a frequency of 1.8GHz.

Although the core frequency and L2 cache have not changed, compared with the Snapdragon 855 Plus based on the Cortex-A76 core improvement, Qualcomm’s main change on the Snapdragon 865 is to use the ARM Cortex-A77 architecture directly on the CPU core.

Androbench test

Androbench introduction: AndroBench is a benchmark application that can measure 4K random storage and storage performance of Android devices, including internal or external storage. Among the Redmi K30 Pro, only the 6 + 128G version uses UFS 3.0, and the other versions use UFS 3.1. In the AndroBench storage test, the UFS 3.1 version of the Redmi K30 Pro has a sequential read speed of 1702.61MB / s and a sequential write speed of 755.23MB / s.

UFS 3.1 is a flash storage solution. Our applications and data reside in flash memory. UFS3.1 is also the latest and fastest flash memory standard in 2020. If flash memory is fast, the performance related to file access will be faster. For example, if you copy a long video from your mobile phone, UFS3.1 will be faster. If you have a large number of photos in your album, it can also be accessed faster.

“Peace Elite” Frame Test

“Peace Elite” is currently one of the most popular shooting games on mobile platforms, and it requires extremely high FPS. The author next played the game in HDR high definition and extreme frame rate.

As can be seen from the chart, the FPS is basically stable at about 59.7 frames, and the game process of more than 15 minutes basically maintains the state of full-frame operation.


Redmi K30 Pro has been preheating the “DaDaDa” linear motor. Which actually refers to the Z-axis linear motor. The previous Xiaomi Mi 10 series was equipped with this motor as standard. Z-axis linear motors can provide a stronger, crisper vibrating feel. Which is gradually or has become the standard for flagship mobile phones.

In the experience of using the K30 Pro. The author felt the game’s 4D vibration sense for the recognition of various game sound effects such as various gun sounds. And vehicle sounds in the game: different scenarios (starting aircraft/jump landing/vehicle collision). Different weapons (AKM / AWM / VSS …), different kills (normal kill/headshot kill / three kills) all have different vibration effects feedback.

The feeling of mobile phone vibration to the user is easy to ignore, and the software’s adaptation to the vibration sensor can better support the hardware performance, thereby further improving the experience.

Vibration is not only a reminder function for incoming calls and text messages. It is also an interactive method. For example, when you are typing, operating the interface, or taking photos, in addition to the screen feedback, there will also be tactile feedback. For example, when deleting a photo, it feels like pressing a physical-mechanical button, there will be vibration feedback, and there will be humming feedback when clearing the status bar notification and clearing the background.

These are all detailed experiences that are difficult to go back to, especially the Redmi K30 Pro. With the support of the MIUI system, customized up to 153 kinds of vibration scenes. And richly optimized for the touch, so when operating the mobile phone. You will feel that the mobile phone interface has been communicating with you closely and responding to everything.

Talk about this screen

In terms of screen quality. The entire Redmi K30 Pro series is equipped with Samsung AMOLED screens as standard. With a refresh rate of 60Hz and a touch sampling rate of 180Hz. It uses a Samsung E3 material with a contrast ratio of 5000000: 1. The maximum brightness of 800 nits, and a peak brightness of 1200 nits and passed HDR10 + certification.

The Samsung AMOLED screen of the previous generation Redmi K20 Pro has a brightness of 600nit (HBM) / 430nit (Typ). And a contrast ratio of 60,000: 1 (Min), so you can see that the screen quality has greatly improved. In other words. Redmi K30 Pro not only has no water drops and no digging holes, but it also has a bright high-definition screen.

Here, I want to share with you the most controversial point of K30Pro before the release-60Hz refresh rate.

My point is that a high refresh rate is a plus for the screen, but it is not an option. After all, the screen experience is not determined solely by the smoothness brought by the refresh rate. But by multiple indicators such as brightness, resolution, color gamut, color accuracy, and refresh rate.

Judging from the paper parameters. The K30 Pro screen can be regarded as a non-curved 60Hz version of the Xiaomi 10 series Samsung screen. The important indicators such as brightness, color gamut coverage, and HDR support are almost the same.

Moreover, there are still many limitations in the current stage of the high refresh rate. For example, not all scenes can be adapted, such as video, such as some mobile games. In addition, considering comprehensive costs and other considerations, the K30PRO has not selected a high refresh rate and is also being cleaned up. As a mobile phone with a major price/performance ratio, the Redmi K30 Pro needs to spend every budget on the most desired configuration of the target group. It makes sense. In.

The lack of a high refresh rate is not a shame for the K30 Pro. The K30 Pro already offers a top-quality screen with a basic quality comparable to that of the Xiaomi 10 series. If you are not worried about the high refresh rate, the easiest way is to add money to consider Xiaomi 10.

Network experience

Consistent with other mainstream 5G flagships at present. Redmi K30 Pro supports SA + NSA 5G dual-module network and supports multiple current 5G frequency bands such as n1, n3, n41, n78, and n79.

Redmi K30 Pro supports Wi-Fi 6. WiFi 6 (802.11ax) is a new generation of WiFi standards. Compared with the previous generation WiFi 5 (802.11ac), it has greatly improved transmission speed, signal coverage, and data delay. When the terminal devices are connected at the same time, matching with the WiFi 6 router can significantly reduce. And reduce the delay and stall of the terminal devices.

Next, we test the performance of the Redmi K30 Pro under the 5G network. First, use the mainstream test tool Speed ​​Test for speed measurement under the 5G network.

The speed of the Redmi K30 Pro5G network is currently stable at around 767Mbps in the author’s test area. And the network speed experience is still much faster than that under 4G. In particular, compared with the 110Mbps downlink rate of ordinary 4G networks. 5G networks have been almost eight times as fast as the former. Not only that, but the latency under 5G networks is also lower.


Whether in the Redmi era or today’s Redmi, batteries have never been an aspect to worry about. And large batteries have almost become their long-established labels.

Sure enough, the Redmi K30 Pro is equipped with a 4700 mAh battery. So its capacity is close to 5000 mAh, and it still counts as a large battery in the 5G era.

The Redmi K30 Pro is also equipped with a 33W wired fast charge on the basis of a large battery. The official said that it can be charged 100% in 63 minutes. Next, let us test the battery life and charging performance of the Redmi K30 Pro through actual measurements.

The author uses the Bilibili client to play online barrage videos, 20% volume. 70% brightness, QQ, WeChat reserved in the background, using a WiFi network. And the mobile network is in 5G state, starting from 99% power, more than 1 hour later, The remaining power is 90%, and the power consumption is 9%.

QQ and WeChat are retained in the background, starting from 89% of the power. And after 1 hour, the remaining power is 77%. The power consumption is 12%. But it should be noted that the picture quality is high definition and the frame number is set to high. If you adjust the image quality and frame rate to a higher level, battery life may be reduced.

The Redmi K30 Pro is equipped with a 33W charge pump for fast charging. The paper parameters are faster than the 30W of Xiaomi 10. We actually measured the blood pressure from 15% to 95% in 50 minutes when the screen is turned on.

Redmi K30 Pro Verdict

For most users, including the author. The current purchase of flagship models for around 3,000 yuan is nothing more than these aspects: processor, screen, camera. Charging life and other details about personal preferences, In many respects. The Redmi K30 Pro has done a very good job. For example, Redmi K30 Pro models equipped with 8-series processors. The peripheral equipment has also been upgraded synchronously, including LPDDR 5. UFS 3.1 memory flash specifications, thermal bearing, antenna design and so on. The gap between flagship processor models and mid-range processor models is far more than the performance gap between paper and running points.

This time the K30 Pro zoom version of the luxury dual OIS, added a larger aperture. And the 865’s ISP and supporting algorithms from the bottom of the blessing. The imaging system has been incomparable to the past, almost become the price hegemony.

Battery Verdict

Whether it is the Redmi of the year or the Redmi now, the big battery has never been a problem. The big battery with a capacity of 4700mAh does not have to worry about battery life. And the actual measurement results are the same. What is more surprising is that the K30 Pro is equipped with a 33W charge pump fast charge. The marvel on the paper parameters is faster than the 30W of Xiaomi 10.

Whether in the evaluation experience of the 65W Xiaomi Mi 10 Pro or in the current evaluation experience of the K30 Pro, we find that they have a common feature: high power time is long enough. This can be clearly found through our test chart in the charging section.

All in all, the Redmi K30 Pro as a Snapdragon 865 flagship. The zoom version can be said to have the strongest imaging system at the same price. And a high-quality 60Hz refresh rate screen, which forms the basis of K30 Pro’s strong competitiveness. Like the previous-generation K20 Pro, the Redmi K30 Pro is Redmi’s flagship with the ultimate price/performance ratio, so you can buy with confidence.
