1. Introduction and pictures
“Redmi is taking on Xiaomi’s past.”
In 2019, Redmi announced its independence, and Lu Weibing was interviewed, which left a deep impression on me. To understand this sentence, you must first know how Xiaomi started, because Xiaomi used to focus on cost performance, and the starting price was almost 1999 yuan.
Redmi’s independence can be regarded as an internal second venture. Unlike the start-up brand, it has the big tree of Xiaomi to rely on, but at that time, Redmi only had a few product lines, and it was best to have only the Note series with the highest positioning.

The biggest problem after independence is to complete the product line, and it can’t conflict with Xiaomi, which is hitting the high-end. How to “revitalize” Redmi? Lu Weibing gave the answer. According to several interviews, the most impressive thing is that he dares to say anything. Someone once commented that this person can be called “Xiaomi’s Yu Chengdong”.
Five months after joining Xiaomi, Lu Weibing brought the Redmi K series product line. As expected, the price starts from 1999 yuan. In the following three years, the K series has been booming, and the K30 series and K40 series have successively exceeded 10 million sales.

If the Note series is the most successful product line of the entire Xiaomi brand, then the K series is definitely close behind. The only difference is the leading edge in different price segments. Therefore, Redmi has not only succeeded in taking over the price/performance ratio of Xiaomi, but also continues to move forward. .
With the passage of time, now the Redmi K series has ushered in the fourth generation, and the performance and screen have been improved again. Can it continue the glory of the big brother?
The machine provides four colors of ink feather/silver trace/mirror mirror/youmang, and this is the ink feather in my hand.

The Redmi K50 has a straight screen on the front and a hole-in-the-middle design. The straight screen is absolutely praised. Although the micro-surface has a high appearance, there are still occasional accidental touches when watching videos and dragging the progress bar. In addition to no accidental touches, the straight screen is used to play games. Also excellent.

The machine uses a 6.67-inch Samsung AMOLED flexible straight screen with a resolution of 3200×1440. It is the first time that Redmi is equipped with a 2K resolution screen and supports 120Hz high refresh rate. Unfortunately, there is no LTPO, but at this price, there is no choice. With a high score screen What more bike.
In addition, there are 16,000-level automatic brightness, 526PPI, ambient color temperature sensing, Dolby Vision, DC dimming and other features, of which DC dimming can only be achieved at a 60Hz refresh rate.

Lens Details
The back of the fuselage is the most unique design, and also the biggest change of the K50 series. The rear camera has a rectangular layout, using a square and round collision design. The decorative ring is similar to the star ring style. At the same time, the lens is made of Super Black to deepen the overall The high-black and high-bright texture is just that the middle frame adopts a plastic middle frame in order to save costs, which affects the texture of the whole machine.
This ink feather in my hand continues the design language of K40. It adopts nano-crystal technology and micro-engraves the crystal pattern on the surface of the diaphragm through lithography. It is officially called the texture design from space olivine meteorite, but personally it feels more like glass Fragmented feeling.

2. System and Highlights
The Redmi K50 runs the stable version of MIUI 13.0.2 based on Android 12. I believe that the functions are familiar, such as small windows, privacy protection, etc., so I won’t say much, just talk about the display mode of the machine.
The Redmi K50 supports 2K resolution and 120Hz refresh rate at the same time, the color style supports customization, there are multiple modes to choose from, and the true color display can be adjusted according to the color that suits you.
Sure enough, there are still ads in built-in apps in this version, such as weather, calendar, etc. Fortunately, it can be manually turned off, so I won’t say much. I hope it will not be turned on by default in the future.
3. Performance and Gaming
In addition to the screen, the biggest upgrade of the Redmi K50 lies in the core. It is equipped with the MediaTek Dimensity 8100 processor for the first time. It is equipped with a full-blooded version of LPDDR5 memory + upgraded UFS 3.1 flash memory, supports atomic memory and IO Turbo, and improves background resident capabilities and file copying. The speed has indeed improved significantly.
Then look at the Dimensity 8100, which uses TSMC’s 5nm process. The CPU consists of four 2.85GHz Cortex-A78 cores and four 2.0GHz A55 energy efficiency cores. It is still the Armv8 instruction set.
In terms of GPU, Dimensity 8100 integrates six-core Arm Mali-G610. The GPU frequency has not yet been announced, but it is 20% higher than that of Dimensity 8000. In addition, APU consists of two performance cores and one general-purpose core. The Dimensity 8000 has a 25% increase, is equipped with the HyperEngine 5.0 game optimization engine, and supports the Dimensity open architecture, providing higher flexibility for device manufacturers to customize the differentiated functions of high-end 5G smartphones.
On paper, the Dimensity 8100 belongs to the sub-flagship level, and its positioning is similar to that of the Snapdragon 870. Compared with the latter’s A77 core, the Dimensity 8100 has an advantage in terms of CPU. Focus on the difference between the Mali-G610 and the Adreno 650. The difference, the specific running points are as follows.
After the actual test, the Redmi K50 AnTuTu score was 846787, which was really surprising. At this time, I found out that the target of the Dimensity 8100 does not seem to be the Snapdragon 870, but the flagship Snapdragon 888, the six-core Mali – G610 can have such a strong performance really did not expect. For a simple comparison, compare the existing Snapdragon 870 and Snapdragon 888 models to see the advantages and disadvantages of the Dimensity 8100. Note that it is only a model of the same price, not a flagship.
Let’s first look at the running points. Under the same environment of the three mobile phones, the Dimensity 8100 has a better running performance, followed by the Snapdragon 888 model and the Snapdragon 870 model.
Compared with the sub-scores, the CPU score of Dimensity 8100 leads the Snapdragon 870 by a small margin, and lags behind the Snapdragon 888. The reason is that the Cortex X1 core has higher performance, but overall, the four A78 cores have higher performance. The performance is enough to run mainstream games smoothly.
In terms of GPU, the Dimensity 8100 has a very strong performance, breaking through 300,000. It can almost be said that it is far ahead of the Snapdragon 870 and closely followed by the Snapdragon 888. Although there is a gap, it is not large. As a sub-flagship, the Dimensity 8100 is Currently the highest performing, bar none.
Just looking at the running points doesn’t seem to be a big surprise? Then the power consumption and heat generation, the Dimensity 8100 can definitely be called the level of conferred gods, to see the actual game performance.

Body temperature
“Honor of Kings” opens the 120-frame mode, which can keep the full frame running. The frame drop during the period is to restart the game. It is normal for the frame to drop during the loading process. Surprisingly, the game is 30 minutes, and the maximum temperature of the Redmi K50 back cover 40.6, the average temperature is only 36.6, the hand-held can hardly feel the heat, I suspected that the high frame rate was not turned on, until the frame rate curve actually measured 120 frames, which was really shocking, I understood it, and was greatly shocked.

Body temperature
Then there is “Genshin Impact”, which can be stabilized to 60fps in the early stage, and then the frame starts to drop 45fps when the body heats up, but according to the frame rate curve is wavy, the reason is running pictures and killing monsters, if you kill monsters, the frame will drop to about 45 , the running map is maintained at around 50, which is better than directly locking to 45.
In terms of heating, the highest temperature is 44, and the average temperature is 39.1. In view of the performance of “Honor of Kings”, this temperature is a bit high. At the same time, after many attempts, it can be concluded that the medium load scene, Dimensity 8100 has an excellent and can be called excellent Under high load conditions, the Dimensity 8100 still generates heat, but in front of the Snapdragon 888, this heat is not worth mentioning.
4. Video and photography
In terms of imaging, the Redmi K50 is equipped with a 48-megapixel main camera (IMX582, OIS) + 8-megapixel ultra-wide-angle + 2-megapixel macro at the rear. This combination is enough for daily code scanning. It is more conscientious to be equipped with optical image stabilization, after all The screen and processor have already taken up a lot of cost, and it is inevitable that the camera of this cost-effective model will shrink.
Before the proofs, it should be noted that the local weather is cloudy and haze, which affects the purity of the picture, and it is due to the engineering machine, which does not mean the final image.

The imaging details are good, and the noise control in the daytime scene is also at the mainstream level. The advantage of this CMOS is to shoot close-up shots, especially the blurred details, the transition is natural, the color reproduction of flowers is accurate, and there is no color cast, but the macro lens is somewhat unsatisfactory. Adjust the angle several times to get a clear macro shot.
5. Battery life and charging
The Redmi K50 is equipped with a 5500mAh battery. Note that it is a single battery, not a dual-cell battery. It is a large battery that is rarely seen at present. How about the low-power battery life with the Dimensity 8100? Let’s take a look at the measured data. It is customary to use the AnTuTu stress test function to perform super power consumption tests.
Stress test is a built-in function of AnTuTu Review. It tests the stability of device performance by performing high-load operations. It requires a lot of calculations on the CPU. Therefore, the power consumption is larger than that of video and daily use. Turn on 2K. +120Hz high brush mode.
In the super power consumption test, the Redmi K50 lasted for 240 minutes, which is really a surprise. It can be comparable to the entry-level model that focuses on long battery life. You must know that this is still in a 2K resolution scene. It is expected that the 1080P mode will have longer battery life.
Compared with a certain model equipped with Snapdragon 870+4500mAh, it takes 170 minutes, and the K50 reaches 240 minutes. It is the model with the longest stress test of the new machine. On the one hand, it is because of the large 5500mAh battery, on the other hand, it is It is the low power consumption advantage of Dimensity 8100.
It should be noted that this result is obtained when the CPU is always at full load. Considering our daily use and screen time, this data needs to be converted into multiples, and it is concluded that the Redmi K50 has a continuous use time of more than 8 hours. , pay attention to continuous use, not to turn off the screen every day, reply to messages, etc.
In terms of charging, the Redmi K50 supports 67W wired fast charging, let’s see how fast it is.
After actual testing, the Redmi K50 took 50 minutes to charge to 100%, of which 44% was charged in 10 minutes and 75% in 30 minutes, which is a normal charging speed for a large 5500mAh battery.
6. Summary
Redmi K50 is a product that exceeds expectations, and it is another benchmark at the same price, especially the front 2K high refresh screen and Dimensity 8100, which interprets what is the ultimate cost-effectiveness, and has a large 5500mAh battery for long battery life. I have to say that this kind of Only Redmi can do the most cost-effective products.
The cost-effective model will inevitably have defects. For example, the rear camera is still 48 million pixel triple camera, but OIS optical image stabilization is added, which is not so sincere. This is the choice made by Lu Weibing. I got everything I wanted, even more than I expected.
Of course, if a product only has enough flash points, it cannot cover up its shortcomings, but if the starting price of 2399 yuan is given on this basis, the nature will be different. The flagship performance of the Dimensity 8100 with mid-range power consumption… If these combinations are added together, it can be predicted that the machine will hit tens of millions of sales again.
Lu Weibing once said in an interview that the people who make products are nothing more than making choices for users. Looking at the entire K series product line, Lu Weibing is undoubtedly a product manager with very accurate insights. Inseparable from the relationship, of course, except for the K30 Pro.
Finally, let’s talk about Redmi. There is no doubt that the brand has successfully taken over the price/performance ratio of Xiaomi. With this, the K series has become another Redmi product line with sales of tens of millions, which has stabilized the cost-effective moat.
I don’t know why, when I see the K50 series, I always think of the Xiaomi spring new product launch last year. The theme of this launch is only four words. After thinking about it, it may be because of the tens of millions of sales of the K series. Transfusion of blood to Xiaomi is the guarantee and foundation of its impact on the high-end. This cycle creates endless growth.
The current Redmi, let me see Xiaomi many years ago, sincere and firm, believe, move forward, and run forever.
