Redmi K30S Extreme Edition Review: 144Hz Display, Snapdragon 865


The Redmi K30 Extreme Edition is equipped with Dimensity 1000+ and AMOLED high-brush screens, and the K30S Extreme Edition is equipped with Snapdragon 865 and 144Hz high-brush LCD screens, providing rich choices for users with different preferences. Regardless of the appearance or the specific specifications, the Redmi K30S Extreme Commemorative Edition is basically the same as its prototype Xiaomi 10T. They all use the Snapdragon 865 5G platform, with LPDDR5 memory and UFS 3.1 flash memory, 6.67-inch LCD screen, support 144Hz high refresh, The rear 64MP main camera + 13MP wide-angle + 5MP macros, equipped with 5000mAh battery, supports 33W fast charge.

The difference is that the price of the Redmi K30S Extreme Commemorative Edition is more fragrant than the overseas Xiaomi Mi 10T. The initial price is only 2599 yuan. With the special subsidy of 300 yuan during the Double Eleven period, the price can be reduced to 2299 yuan. Below, there is currently no opponent at the same price that can challenge it. It can be called a double 11 big killer, a generation of magic machines for user groups that focus on high-cost performance.

Design & Appearance

The Redmi K30S Extreme Commemorative Edition uses a 6.67-inch LCD material perforated full screen with a resolution of 2400*1080. Support P3 wide color gamut, color accuracy is quite high, JNCD≈0.39, Delta E≈0.63, pixel arrangement is real RGB, without sacrificing display accuracy, display details are better than the drill row OLED screen of the same resolution.

The high refresh rate of 144Hz makes it stand out among the models of the same price. Perhaps it is precisely to pursue the 144Hz refresh rate that LCD screens were chosen. LCD changes the brightness of the red, green, and blue sub-pixels by independently controlling the current of each liquid crystal cell. In principle, it is easier to achieve a high refresh rate than an AMOLED screen.

The specific size of the Redmi K30S Extreme Commemorative Edition is 165.1×76.4×9.33mm and the weight is 216g. In the new camera arrangement method, the entire camera module is placed in the “matrix” in the upper left corner.

Taking into account the injection molding antenna and the edge sealing at the power interface, the frame should be made of metal. As just said, the Redmi K30S Extreme Commemorative Edition uses an LCD screen, so fingerprints cannot be placed under the screen, so it uses a capacitive side fingerprint unlocking design and has a two-in-one power button and fingerprint unlocking design.

Hardware & Performance

The performance platform of the Redmi K30S Extreme Commemorative Edition and the matching things are all familiar old friends. However, it is quite sincere to be able to match the Snapdragon 865, LPDDR5 memory, and UFS 3.1 flash memory at the price of 2,000 yuan.

GeekBench test

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

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

The CPU core used by the Snapdragon 865 is a 1+3+4 architecture with frequencies of 2.84GHz, 2.42Ghz, and 1.80GHz. And the 1+3 large cores have been upgraded to the Coterx-A77 architecture, and the 4 small cores are still Cortex-A55 architecture with a frequency of 1.8GHz.

GFXBench test

Introduction to GFXBench: Cross-platform, cross-API 3D benchmark 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 testing.

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

There are six main test items: T-Rex, Manhattan 3.0 (Manhattan), Manhattan 3.1 (Manhattan), and Car Chase, which correspond to the performance under the OpenGL ES 2.0/3.0/3.1/3.1 standard. In addition, there are also newly added Aztec ruins Vulkan off-screen, Aztec ruins OpenGL off-screen, the test pressure is getting higher and higher, and the results are measured by the average frame rate (FPS). The normal performance of the Snapdragon 865 model.

In terms of network speed, we have also tested it. In addition, considering that the construction progress of operators in various regions is different, the final measured 5G network speed may be different from the actual measured results.


In the impression of many people, LCD screens are inherently inferior to AMOLED, but they are actually a bit one-sided. Redmi K30S Extreme Commemorative Edition, as a rare LCD screen flagship today, has many advantages over OLED screen models: there will be no flicker problems caused by no PWM dimming; it can provide more refresh rate gears, Flexible interpretation of different dynamic pictures.

During the experience, we found that the Redmi K30S Extreme Commemorative Edition may be the current model with the most refresh rate gears. Not only does it open the 60Hz, 90Hz, and 144Hz gears that can be manually adjusted, it actually provides an additional 48Hz, 50Hz, and 120Hz. The gears, etc., can better align images of various frames.

Take the Bilibili video client as an example. When the barrage is closed, the refresh rate is automatically adjusted to 50Hz, and when the video barrage is turned on (the barrage speed is set to fast), the refresh rate reaches 144Hz; refresh when the desktop is still The rate is 50Hz, and the refresh rate rises to 144Hz when sliding the desktop.

Simply put, the adaptive refresh rate achieved by the Redmi K30S Extreme Commemorative Edition can indeed automatically adjust the refresh rate of the display according to the movement of the displayed content, eliminate screen tearing, delay, and lag, and improve the display experience. When you need to eliminate screen tearing and improve display quality, the refresh rate is automatically increased. When watching videos with lower frame numbers and static displays, the refresh rate is automatically reduced to reduce power consumption, which can significantly improve battery life.

In addition to top flagship performance, adaptive high refresh rate screen with software algorithms in place. The Redmi K30S Extreme Commemorative Edition also has many other perfect flagship experiences, such as dual speakers, X-axis linear motors, full-featured NFC, infrared.

For example, the bottom speaker and the two-in-one earpiece speaker on the top of the fuselage can form a stereo speaker, which can enhance the on-site experience for users who like playing games and watching movies outside.

As a Snapdragon 865 flagship with a price of 2,000 yuan, the Redmi K30S Extreme Commemorative Edition even uses an X-axis linear motor (most of the same price uses a rotor motor and a Z-axis linear motor), which is extremely rare. The vibration feeling is short and powerful, without procrastination. With delicate adjustment and optimization, the delicate vibration feedback of typing, games, and other scenes is not inferior to some of the more expensive flagship models.


The imaging system of the Redmi K30S Extreme Commemorative Edition is not complicated and is more like the previous Redmi K30 Extreme Commemorative Edition. The classic Sony IMX682 64 Megapixel main camera + 13 Megapixel ultra-wide-angle lens + 5 Megapixel macro lens combination, the overall standard is also similar to the Redmi K30 Supreme Commemorative Edition. It’s just that the macro sub-photograph is not a telephoto macro, but an ordinary macro lens.


The K30S Extreme Commemorative Edition comes standard with a 5000mAh battery, which is relatively rare in the current flagship models. Here we also conducted a simple test on the battery life of the Redmi K30S Extreme Commemorative Edition.

Use Bilibili software to play 1080P online video, 70% brightness, 30% volume, and the power consumption statistics are shown in the figure. From this, it can be estimated that the K30S Extreme Commemorative Edition has more than 11 hours of life in this condition.

This is the 33W charge pump fast charge that we are more familiar with, which can recover blood from 0% to 100% in 60 minutes.

After finishing this evaluation experience, we found that the Redmi K30S Extreme Edition is not an enhanced upgrade of the Redmi K30 Extreme Commemorative Edition like its name. Together, the two are more like two parallel lines on the same plane, each going in different directions.

For example, in the image section, the Redmi K30S Extreme Edition is not upgraded compared to the K30 Extreme Commemorative Edition. The introduction of LCD screen material brings a higher refresh rate and more flexible variable refresh rate adaptation, but the relative peak brightness of the screen is Reduced by.

But from other aspects, the Redmi K30S Extreme Commemorative Edition has completed a leap-forward upgrade from the Dimensity 1000+ platform to the Snapdragon 865 platform compared to the K30 Extreme Edition, as well as a new appearance design, and it has also received a larger 5000 millimeters. These are also real upgrades for the large ampere-hour battery.

So it seems that the Redmi K30S Extreme Edition is the flagship of the K30 Extreme Commemorative Edition side by side, but the former pays more attention to performance and mainstream design, and it is the only option for LCD enthusiasts to buy mobile phones in the same price range.

Most importantly, Xiaomi officially declared that the Redmi K30S Extreme Edition is a “Double 11 Special Offer”. With a special subsidy of 300 yuan during Double 11, the K30S Extreme Commemorative Edition will be available for 2,299 yuan, which is nothing at the same price. On the right, there is no one that can play. In the face of the ultimate price-performance ratio, the Redmi K30S Extreme Commemorative Edition makes it difficult to resist.
