Finally, we also conducted a flash memory read and write test on the K70E . The sequential read speed was 2.73GB/s and the write speed was 2.94GB/s, which is in line with the performance level of UFS 4.0.
Game actual test
Running scores can only represent theoretical performance, and the actual performance of the game can tell everything.
Next, let’s conduct actual game play to see how the K70E’s Fury Engine 3.0 adjusts to the Dimensity 8300-Ultra.
For game testing, we selected three representative mainstream mobile game masterpieces with low, medium and high loads, namely “Honor of Kings”, “Peace Elite” and “Genshin Impact”, in an indoor office environment of 23 degrees Celsius. Next, the test was conducted with frame rate priority, and the frame rate, power consumption, energy efficiency ratio and body temperature performance during the game were recorded.
1. King of Glory
We first tested the lower-load Honor of Kings mobile game, using extremely high frame rate testing in extreme image quality. The game ran at 964×2146 resolution and 120 frames. After a fierce team battle, you can see the screen The frame rate is very stable, with only a slight fluctuation, but it does not affect the stability of the picture. The final average frame rate is maintained at 119.6FPS, with an average fluctuation of 0.6.
The average power consumption is about 3.31W, the frame energy consumption is 27.7mW, and the energy efficiency ratio is 36.1FPS/W. Compared with Dimensity 8200, the energy efficiency ratio has increased by about 8.8%.
In terms of temperature, the maximum temperature on the front of the fuselage is 39.1 degrees Celsius, and the maximum temperature on the back is 39 degrees Celsius. You will feel a little bit of heat when holding the phone with both hands while playing games.
2. Peace Elite
Then we tested the medium-load mobile game Peace Elite, which could turn on 90 frames in smooth image quality. After a team battle, the frame rate curve was also very stable, with the average frame rate maintained at 89.2FPS, close to full frame, and the average fluctuation was only There are 0.9.
In terms of power consumption, the average power consumption has reached 4.32W, the frame energy consumption is 48.14mW, and the energy efficiency ratio is 20.6FPS/W. Compared with 8200, the energy efficiency ratio is about 13.9% worse.
The maximum temperature on the front of the fuselage is 40.6 degrees Celsius, and the maximum temperature on the back is 40.5 degrees Celsius.
3. Original God
This time, the Dimensity 8 series chip finally managed the high-load Genshin Impact mobile game with ease, running the map and fighting monsters at the same time. The average frame rate was stable at 59.8FPS, with an average fluctuation of only 0.9. There was almost no screen jitter during the game.
Then I checked the power consumption. The average power consumption was 5.94W, which is close to 6W. However, the energy efficiency ratio still reached 10.1FPS/W, which is a relatively ideal result.
In terms of temperature, the maximum temperature is 43.3 degrees Celsius on the front and 44.1 degrees Celsius on the back. The high temperature areas are mainly concentrated around the camera module.
Cameras
Redmi K70E has three rear cameras. The main camera has been upgraded from the previous 48-megapixel IMX582 to a 64-megapixel OV64B lens. It has a 1/2-inch photosensitive unit and supports OIS optical image stabilization. The ultra-wide-angle lens is an 8-megapixel OV08D10, coupled with a 2-megapixel macro lens.
Redmi K70E’s OV64B main camera, with the blessing of Dimensity 8300-Ultra’s 14-bit HDR-ISP Imagiq 980 image processor, displays more dazzling colors in daytime scenes, but the color reproduction is still relatively accurate. High-rise buildings and The sky behind has become more layered, but when faced with the light, the sample is still a bit white.
The 8-megapixel ultra-wide-angle lens automatically corrects distortion. Although the picture may be a little narrow, it can still show the tension of the photo when facing some wide architectural spaces.
Battery
Redmi K70E not only maintains the large 5500mAh battery of the previous generation, but also increases the charging power to 90W.
In this regard, we also conducted a series of tests on the charging speed and battery life of the mobile phone.
Charging test
Before charging, we first activate the fast charging acceleration function in the mobile phone manager, and the words “90W MAX” will be displayed in the charging interface.b. The Redmi K70E battery test started from 1%, charged to 28% in 10 minutes, 53% in 20 minutes, 74% in half an hour, and finally fully charged in 43 minutes. With this charging speed, when the phone is out of power, it can recover more than half of its health in the time it takes to go out for a meal, ensuring our daily use experience.
Endurance test
For battery life testing, we use a professional battery life testing tool – Battery Dog produced by Kuai Technology.
In the test items, the 20% power test will be performed by default . At the same time, all test items including CPU high voltage, CPU multi-threading, AI recognition, picture browsing, video playback and web browsing will be checked to simulate user usage scenarios. , to restore the real load to the greatest extent and be infinitely close to the real power consumption.
During the test, in order to ensure that the environmental variables tested for all models remain consistent and the test results are accurate, Battery Dog will automatically adjust the screen brightness to 50%, turn off automatic brightness, and adjust the volume to 30%.
After continuous uninterrupted testing by Battery Dog, the Redmi K70E battery was tested from 100% to 20%, and the battery life was 6 hours, 58 minutes and 18 seconds, which is close to 7 hours. After calculation, the full battery life is about 8.5 hours, which is enough for users to use it for one day.
Verdict
As a new-generation performance pioneer, we did not expect the Redmi K70E to win the first launch rights of Dimensity 8300-Ultra. After all, the previous Dimensity 8 series chips were first launched by OV.
Redmi K70E, as the new generation of flagship model from 2023 to 2024, is not only more radical in performance but also has image upgrades, screen upgrades, and charging upgrades. This generation of Redmi has made comprehensive innovations in all aspects.
After this period of experience, we make the following summary of Redmi K70E:
The Dimensity 8000 series has always been a high-profile representative of sub-flagship chips. The new generation of Dimensity 8300-Ultra fully inherits the flagship features of Dimensity 9300. The same flagship process, memory flash specifications, ISP, Al architecture, etc. are completely inherited from the same origin.
Redmi K70E is the world premiere of Dimensity 8300-Ultra. After in-depth joint debugging with MediaTek, the measured GPU performance has nearly doubled compared to the previous generation. The overall performance has surpassed last year’s Qualcomm flagship chip full-blooded Snapdragon 8+. , which can be called the Dimensity chip with the largest performance improvement in history.
After actual game testing, Dimensity 8300-Ultra achieved Genshin Impact full-frame output for the first time among 8-series chips. However, the prerequisite for full frame is high power consumption and high heat. Of course, this is also inseparable from Redmi’s Fury Engine 3.0. Optimization and performance first have always been Redmi’s genes.
In other words, Dimensity 8300-Ultra is simply the twin brother of Dimensity 9300, truly invincible in its class.
Equipped with OIS optical anti-shake and new CMOS, the imaging capabilities of Redmi K70E have been greatly improved compared to the previous generation K60E in terms of noise control and night imaging.
In terms of charging and battery life, while maintaining a large 5500mAh battery, the fast charging power has been increased to 90W, which is consistent with this year’s Xiaomi super-large model 13 Ultra. It can be fully charged in 43 minutes, which also makes this model sell for less than Mid-range mobile phones starting at 3,000 yuan enjoy a flagship-level charging experience.
In summary, Redmi has fully upgraded the hardware specifications, such as 1012+1216 three dimensional dual speakers, 0809 type The hardware configuration has been raised to a new level, which also makes the Redmi K70E, which has sufficient performance, screen, and imaging, become the most comprehensive among the Chinese smartphones in the price range of around 2K. cup mobile phone.
