Redmi K30 5G Review: Totally Different Phone as Compare 4G Version

0

Redmi, who took over Xiaomi’s “price-effective butcher”, took on the mission of “smashing the ground” and returned to the 1999 yuan dream price of Redmi K30 5G, which achieved the exaggerated lowest price in the industry and stood at the sale level. The price of 5G mobile phones that are generally over 3,000 yuan is particularly eye-catching.

Moreover, the dazzling part of Redmi K30 5G is not just price-friendly. On the basis of cheapness and generosity, it first launched a 7nm process Qualcomm Snapdragon 765G integrated 5G chip, and it was first equipped with a Sony IMX686 CMOS as the main camera. Four cameras, equipped with 4500mAh battery, 120Hz high refresh rate screen, 30W fast charge, from the hardware specifications alone, it has reached the level of flagship models.

In addition, compared with the more “cruel” Redmi K30 4G version, the Redmi K30 5G also has obvious upgrades: the Snapdragon 730G is upgraded to the Snapdragon 765G; the dual-frequency GPS is added; the rear macro lens is upgraded from 2 million pixels to 500 10-megapixel, partially-distributed back cover glass changed from glossy glass to AG matte.

Earlier we reviewed and experienced the Redmi K30 4G version, and the 5G version that was released with one of them has finally arrived as expected today, and then our detailed evaluation.

Design & Appearance

After the forehead of the mobile phone dominated by water droplets and the lifting structure, the dug-out screen for a brief period of silence was back to spring, and it came back with double dug-outs. At present, there are glory and OV 5G models on the market that are about to be released. Due to the larger heat dissipation area and battery capacity required in the 5G era, hole-screening will almost certainly become the mainstream design of mobile phones in 2020.

The previous waterdrop screen was used by major manufacturers for a year. During this long time, I believe that everyone has gradually found that the water drop display area and the top border are not beautiful enough, and the digging screen will make the screen look It will be more complete. But before the technology of the hidden camera under the screen is completely mature, whether you like it or not, the digging screen will replace the waterdrop screen and become the mainstream full-screen design.

As the volume of the front camera module continues to shrink, the digging radius will continue to shrink. At present, the opening diameter of the Redmi K30 5G is only 4.38mm, which is said to be the smallest opening design at present.

The screen size of Redmi K30 5G is already quite large, reaching 6.67 inches, the screen ratio is 20: 9, and the screen material is familiar LCD. This screen supports a refresh rate of up to 120Hz, which is also the only one among the thousand yuan phone should be known that when the 90Hz high refresh rate mobile phone screen was first born, it was used by many manufacturers as a game phone. Later, after the 120Hz higher refresh rate screen appeared, it was placed on its top gaming flagship by ROG phones.

Regarding the back of the fuselage, the styling contours of the Redmi K30 4G version and the 5G version are exactly the same. There are two main differences between the two:

1. The Redmi K30 4G version currently only offers three color combinations: Purple Jade Fantasy (purple), deep-sea light (blue), and Huaying Jinghong (red gradient); Redmi K30 5G version has an extra time monologue (white).

2. The back glass of the Redmi K30 4G version is a common ordinary glossy glass, and the 5G version of the purple jade fantasy and time monologue is made of AG frosted glass.

Obviously, the 5G version has a slightly higher selection and exquisiteness. I personally like the 5G version of the time monologue.

The Chinese-style design of the rear camera was nicknamed the “coin phone ” by netizens before the official release of the exposure stage. Interestingly, Redmi is glad to accept the non-malicious name of the “coin phone “.

Lu Weibing, general manager of the Redmi brand, also stated publicly: “After the K30’s exterior photos were announced, many rice noodles called this design a” coin phone “, and a lot of pictures were made. I was surprised at first because we did not consider it “Coin phone ” design, but when you think of it, Mi Fen likes to call it anything. “Coin phone ” design is very high-end. 

In fact, aside from official jokes such as “coin phone “, the back design of the K30 series is very creative and bright (after all, no model has done this before), and it has practical value. When you use your phone to take pictures When shooting, the subject ’s gaze will naturally fall on the camera area, making it easier for users to capture natural and communicative portrait photos.

This is the first time that Redmi has used the side fingerprint recognition module. The power button and fingerprint recognition have been done together. There is no need to worry about the unlocking speed, and the finger can be attached to complete the unlocking. K30 5G’s fingerprint recognition power button is slightly higher than the plane of the frame. The touch of your finger will make you feel that there are long bumps on the frame.

In addition, the K30 uses a plastic matte middle frame, which should be for signal and cost considerations. This is the top and bottom details of the fuselage. The intimate reservation of the 3.5mm headphone jack impresses me, the old 3.5mm headphone users who often lose the adapter. The Cato of Redmi K30 5G does not support micro SD card expansion, but the 4G version supports it. In general, the appearance of Redmi K30 5G, the purple jade fantasy, and the time monologue are made of AG frosted glass, and other aspects are unchanged compared to the 4G version.

Hardware & Performance

The Redmi K30 5G’s first launch of the Snapdragon 765G is Qualcomm’s strongest 7-series mobile platform so far. It is also the largest upgrade since the release of the Snapdragon 7 series. The GPU performance has increased by 40% and the AI ​​computing power has increased by 100%.

In terms of performance, the Snapdragon 765 series integrates eight-core Kryo 475 CPU, Adobe 620 GPU, Spectra 355 ISP, Hexagon 696 DSP, sensor hub and other modules.

With a fifth-generation AI engine, the Hexagon tensor accelerator is twice as fast as the previous generation, the display supports a 120Hz refresh rate, the memory supports dual-channel LPDDR4X-2133, and the maximum is 8GB. The fast charge supports QC4 + / QC AI, and the satellite positioning and navigation support Beidou.

From the frequency point of view, the Snapdragon 765 CPU frequency is up to 2.3GHz, and the Snapdragon 765G is increased to 2.4GHz. Its AI performance is up to 5.5 trillion operations per second (5.5 TOPS), and graphics rendering speed is increased by 10% with the support of enhanced Adreno GPU.

Taken together, the Snapdragon 765G has huge improvements in CPU, GPU, AI capabilities, and network connectivity. It is almost the largest upgrade of the Qualcomm 7 Series since its launch. In conjunction with NSA / SA dual-mode 5G, comprehensive capabilities Much higher than previous Qualcomm 7 series chips.

1.Master Lu

Master Lu can score and compare the five core hardwares of CPU, GPU, RAM, storage, and display. Even ordinary white users can use him to understand mobile phone related information.

According to Master Lu’s evaluation system, the running score of the Redmi K30 5G equipped with Snapdragon 765G is roughly equivalent to the current Snapdragon 845 models and is close to Xiaomi MIX3.

Geekbench

Geekbench is a cross-platform CPU evaluation software that can accurately evaluate the CPU’s single-core performance, multi-core performance, and daily usage load. You can also evaluate the computing power of the GPU.

There are currently two different versions of Geekbench at the same time. The latest version has greater changes in running weights and rules than the previous version, so we ran Geekbench 4.4.0 and Geekbench 5.0.3 at the same time for reference.

In terms of the Snapdragon 765G CPU, Kryo475 has the same architecture as the Snapdragon 855, uses a new eight-core Kryo475 processor, a 1 + 1 + 6 three-cluster architecture, and is equipped with a 2.4GHz super core and a 2.2GHz performance Core, six 1.8GHz efficiency cores.

In Geekbench’s evaluation system, the performance of the Snapdragon 765G is higher than that of the Snapdragon 730. The Geekbench 4.4.0 of the Redmi K30 4G we tested before has a single-core score of 2551 and a multi-core of 7095, which are 13% and 12% respectively.

3.GFXBench test

GFXBench profile: Cross-platform, cross-API 3D benchmarking software that accurately reflects the graphics performance of the device’s GPU. Multiple test scenarios can fully investigate the OpenGL ES graphics performance of the device and can perform battery life tests.

GFXBench provides two test comparison methods: OnScreen and OffScreen. When the screen is running, the test is run at the native resolution of the device screen. When the screen is off, it is unified to 1080p resolution, which is convenient for cross-device comparison.

There are six main test items: T-Rex, Manhattan 3.0, Manhattan 3.1, and Car Chase, which correspond to the performance under the OpenGL ES 2.0 / 3.0 / 3.1 / 3.1 standards. There are also newly added Aztec ruins Vulkan off-screen and Aztec ruins OpenGL off-screen. The test pressure is getting higher and higher, and the result is measured by the average frame rate (FPS).

The Snapdragon 765G graphics processor uses the new Adreno 620. Thanks to the same architecture as the new flagship Snapdragon 865, the graphics computing performance is improved by nearly 40% compared to the Snapdragon 730. In Manhattan 3.0 off-screen test, it has increased by 38 %, In the 3.1 off-screen test in Manhattan, an increase of 35%, and in the Car Chase off-screen test with a larger load, the Snapdragon 765G increased by 34%.

4. 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.

Models using the Snapdragon 7 series platform have always been accustomed to using single-channel UFS 2.1, and the continuous reading speed is basically stable at 500MB / s, such as the Redmi K30 4G version equipped with Snapdragon 730G in the above comparison.

The Redmi K30 5G obviously uses dual-channel UFS2.1 here, and the speed test results of almost every item are twice that of the former. Based on this, the Snapdragon 765G is indeed the last regret that the Snapdragon 7 Series platform models have long existed.

120Hz Screen

High refresh rate screens must be the common selling point of most smartphones in 2020. “90Hz”, “120Hz” and even “144Hz” parameters commonly used in computer monitors are now gradually entering the attributes of smartphones. Be caught off guard.

When it comes to the refresh rate Hz, we have to mention the frame rate fps. The refresh rate Hz refers to the display refresh rate, which indicates the physical refresh rate of the display. For example, the OnePlus 7 Pro’s 90Hz screen can refresh 90 pictures in one second, and other 60Hz screen models refresh 60 pictures.

Frame rate refers to the speed of the picture refresh rate. For example, 80fps means that 80 pictures are refreshed in one second. The frame rate is usually affected by the graphics processor of the device. The stronger the graphics processing capability, the higher the frame rate.

For example, if the frame rate of a mobile game is stable to 80fps, but the display only supports 60Hz, then the 80fps frame rate cannot be expressed on the display, because the display can only display 60 frames per second, which is wasted. In other words, if you really want to experience the high frame rate, you must have the display device in place to experience the smoothness of the high frame rate.

This time we also simply tested the frame number of commonly used apps by the way:
  • 1. The average frame rate of the MIUI system App can approach 120 frames.
  • 2. The average frame rate of apps including social media, e-commerce, etc. including QQ, Weibo, Jingdong, etc. is also above 110 frames.
  • 3. The average frame rate of mobile phone Taobao is around 90 frames, and WeChat can exceed 100 frames.
  • 4. The upper limit of the picture frames of “Glory of the King” and “Peace Elite” is locked at 60 frames and 40 frames respectively.

Therefore, in terms of the visual experience of most commonly used applications, Redmi K30 5G is definitely better than other ordinary models. As for the game, it needs to be acknowledged that the current 120Hz screen performance of the two games, “Glory of the King” and “Peace Elite”, is no different from the 60Hz ordinary screen.

5G network speed experience

In terms of network speed, we use mainstream Speedtest software for testing. It needs to be mentioned that there may be differences in the network environment of different regions and different operators, so the measured 5G network speed may be different from the actual measurement results that everyone buys Out.

It can be seen that in our test environment, the download speed of the 5G network of the Redmi K30 5G mobile phone is 25 times that of the 4G network, and the upload speed is 7.5 times that of the latter.

In such a 5G network environment, downloading the application can achieve the effect of reading the progress bar immediately after clicking, and there is almost no loading time when the webpage is opened. Click to open the page. Pull the progress bar of 1080P online video at will, you can hardly see any buffer under the 5G network environment, and the buffering is basically completed in an instant.

The author has always been concerned about network delays. Next, we tested the delays in daily use scenarios. The specific test solution is reproducible for everyone-ping u homepage. I will use, Redmi K30 5G ping under the etwork to compare the test results under a network.

The above is the delay performance of Redmi K30 5G ping Baidu under 5G and 4G networks. It can be seen that the average delay under the 4G network is 80ms, and the average delay under the 5G network is 25ms.

The 5G average network delay of the Redmi K30 5G is about 55ms lower than in the 4G network environment. It can be said that the improvement is obvious, and there is still a distance from the theoretical 1ms delay under ideal conditions.

Mainly because the current 5G phase is dominated by the NSA networking mode, the user plane transmits through 5G, and the control plane signaling still transmits through 4G. In other words, the total delay in the non-independent networking mode is the 4G control plane signaling delay plus the 5G user plane delay, and then the Internet delay.

Therefore, at the current stage, it is not only the game delay that is subject to the operator. The network delay of all 5G mobile phones under daily use cannot be significantly improved. Only in the future when the SA networking model is perfected and the obstacle of signaling delay of the 4G control plane is kicked off, lower and more ideal delays can be realized.

It is worth mentioning that the Redmi K30 5G fully supports the SA / NSA 5G dual-module network. That is to say, it can be smoothly transitioned and used normally under any network environment.

Cameras

The Redmi K30 series is not Xiaomi’s first 64-megapixel model. The Redmi Note8 Pro released in June last year launched the 64-megapixel Samsung GW1 in the world. The K30 series is also the world ’s first 64 million pixels this time, but the first target is replaced by Sony IMX686, which is also equipped with an 8-megapixel ultra-wide-angle lens, a 5-megapixel portrait lens and a 5-megapixel macro lens (4G version). It is 2 Megapixels).

1. Day proofs

As shown above, the Redmi K30 does not have a telephoto lens. It achieves a similar optical zoom function by cropping and zooming in on 64-megapixel photos. The effect is still good.

The other three rear lenses are: ultra-wide-angle lens, 8 megapixels, 1.12 microns, 120-degree wide-angle; depth-of-field lens, 2 megapixels, 1.75 microns (mainly used for background blur in portrait mode); ultra-macro lenses, 5 million pixels, 1.75 microns, supports AF autofocus. Compared with the powerful main camera, these three lenses have a large gap (the cost pressure brought by Sony IMX686 is already quite large), and the pictures taken will have obvious chromatic aberration, and the emphasis is on increasing playability.

This camera module is almost the same as the Redmi Note 8 Pro we reviewed before, the only difference is that the main camera has been replaced by Sony IMX686.

2, Night proofs

Thanks to the large size of the Sony IMX686 sensor, low light can be captured clearly. It is said that the rear camera of the Redmi K30 uses the same algorithm as the Xiaomi CC9 Pro, which supports the “Night God” super night scene.

After the rience, the author believes that its performance under the city night scene can be equal to many flagships that have been used before, and the more extreme dark light scene is still not enough to shake the flagship status, but it is better than all the same price points that I have used. product.

Battery

The big battery is the trend. Even Apple, which has been cautious about battery capacity, has expanded its iPhone 11 Pro Max to 3500 mAh. The Redmi K30 now controls the battery capacity at 4500 mAh. The 5G version with the most advanced 7nm EUV process performance of the Snapdragon 765G is better than the 4G version. Let ’s take a look at its performance.

Clear the background, I use Bilibili client to play online barrage video, 20% volume, 70% brightness. Starting from 95% power, after 1 hour, the remaining power is 84%. Power consumption is 11%.

In the test, we started to charge from 21% of the power and rushed to 86% in 30 minutes, and 94% in 40 minutes. It didn’t take much time to make the 4500mAh large battery full.

Verdict

Looking back at the year from Redmi to Redmi’s independence, there are new products almost every month, all of them are very exciting: The Little King Kong series has sold 26 million units in 11 months. The Note8 series shipped over 10 million units in three months. Airdots sold over 7.5 million units in eight months. Relatively low-profile notebooks and Redmi TVs have also achieved the highest sales in the online market.

Behind this, it is the Redmi digital series starting at 799 yuan that actually appeared Corning GG and Type C charging ports; Xiaojingang starting at 999 yuan first proposed an 18-month warranty; almost all Redmi mobile phones above 1,000 yuan are equipped with 18W standard. Fast charge.

It can be said that after Redmi became Redmi independently, it still succumbed to the ultimate price-performance ratio, but paid more attention to the pursuit of quality than in the past. When it comes to the Redmi K30 series, it not only brings the 120Hz high refresh rate screen to the thousand yuan phone but also brings the 64-megapixel Sony IMX686 to the entry model. The significance is more significant than the previous 5G models. The price of the waist cut, like the “hitting the ground”, stirred the 5G mobile phone market.

Returning to the product itself, the Redmi K30 5G’s strategy is very clear. It is the ultimate price/performance ratio. It should be stacked as much as possible in the configuration. At the same time, it should make some appropriate choices to shake consumers’ hearts with the expected lower price. Just like the previous Redmi K20 Pro 8 + 512GB Exclusive Edition, the flagship product of this core configuration is priced at 2399 yuan, which is cheap and affordable.

The same strategy continues on the Redmi K30 5G. It pulls the 120Hz screen that was once held by the game phone into the thousand yuan phone camp. The 64 million IMX686 that was launched on the first day makes it perform better than some cameras in the daytime. The flagship of 4500mAh large battery and 30W fast charge, NFC, infrared and even 3.5mm headphone jack all make this phone can’t pick out the details in the price range starting from 1999 yuan. In terms of 5G networks, the download speed of the 5G network of the Redmi K30 5G mobile phone is 25 times that of the 4G network, and the upload speed is 7.5 times that of the latter.

In terms of performance, Redmi K30 5G has made an improvement compared to its 4G version, upgraded from Snapdragon 730G to Snapdragon 765G, and single-channel UFS 2.1 to dual-channel UFS 2.1.

According to Master Lu’s evaluation system, the running score of the Redmi K30 5G equipped with Snapdragon 765G is roughly equivalent to that of the current Snapdragon 845 models, which is close to that of Xiaomi MIX3. In the evaluation system of Geekbench, the Snapdragon 765G is relative to K30 4G. The Snapdragon 730G CPU has a single-core increase of 13% and a multi-core increase of 12%; the same architecture of the Snapdragon 765G graphics processor and the new flagship Snapdragon 865 improves graphics performance by nearly 40% compared to the Snapdragon 730.

Whether it is the Redmi K30 4G whose price is as low as 1599 yuan or the Redmi K30 5G with a 1999 price of 5G mobile phones, users can get the flagship experience in some areas. Among them, Redmi K30 5G as “the first 5G mobile phone for young people” compared to the starting price of 1999 yuan is said to be “make a friend” is not excessive.

If you are not in a hurry to upgrade 5G, and you want to wait for the 5G tariffs to be gradually lowered and the 5G construction to be fully completed, then “check-in and get on the car”, and have higher requirements for a comprehensive experience beyond the high refresh rate screen and performance. The price is sensitive, so the 4G version of K30 can be completely included in the first choice. For those who want to upgrade 5G but can’t afford too much budget, the Redmi K30 5G version is “cheap and sufficient”, with a minimum cost of 1999 yuan. It is really worth it.
