1. Preface and Reward
"Redmi is taking on Xiaomi's past."
In 2019, Redmi declared independence, lu Weibing was interviewed, and this sentence left a deep impression on me. To understand this sentence, we must first know how Millet started, because Xiaomi once focused on cost performance, and the starting price was almost 1999 yuan.
Redmi independent can be regarded as an internal secondary venture, and the start-up brand is different, there is a big tree of millet to rely on, but at that time Redmi only had a few product lines, the best and highest positioning only note series.
The biggest problem after independence is to complete the product line, and can not conflict with xiaomi that has impacted the high-end, how to "revitalize" Redmi? Lu Weibing gave the answer, according to a number of interviews, the most impression is that he dares to say anything, some people have commented, this person can be called "Xiaomi's Yu Chengdong".
Five months after joining Xiaomi, Lu Weibing brought the Redmi K series product line, and sure enough, the pricing was from 1999 yuan, and then in the past three years, the K series has broken through, and the K30 series and K40 series have successively exceeded tens of millions of sales.
If the Note series is the entire Xiaomi brand and shapes the most successful product line, then the K series is absolutely close behind, the difference is only the leading edge of different price segments, so Redmi not only successfully took over the cost performance of Xiaomi, but also continued to move forward.
With the passage of time, now that the Redmi K series has ushered in the fourth generation, the performance and screen have improved again, can it continue the glory of Big Brother?
The machine provides four colors of ink feather / silver trace / magic mirror / ghost, and this one in my hand is ink feather.
Mobile phone packaging
The phone packaging is printed with the words 67W/2K
Front of the phone
Redmi K50 front straight screen, center digging hole design, of which the straight screen is absolutely praised, micro-curved although the value is higher, but watching the video drag progress bar or accidental accidental touch, straight screen in addition to no accidental touch, used to play the game is also excellent.
The machine uses a 6.5-inch Samsung AMOLED flexible direct screen, the resolution is 3200x1440, is the first time that Redmi is equipped with a 2K resolution screen, support 120Hz high brush, unfortunately there is no LTPO, but this price point is not to pick, with a high score screen and what a bicycle.
In addition, there are 16,000 levels of 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.
The back of the phone
Lens details
The back of the fuselage is the most unique design, but also the biggest change of the K50 series, the rear camera is a rectangular layout, using a square and circular collision design, the decorative ring is similar to the star ring style, while the lens has done Super Black, deepening the overall high black and bright texture, but the middle frame in order to save costs, the use of plastic middle frame, affecting the texture of the whole machine.
This ink feather in my hand continues the K40 design language, using a nano-microcrystalline process, through lithography to micro-engrave the crystal style to the surface of the diaphragm, officially called the texture design from the space olive meteorite, but personally feel more like the feeling of glass shattering.
Package comes with a 67W charger
Second, the system and highlights
Redmi K50 is running a stable version of MIUI 13.0.2 based on Android 12, and the functions are believed to be more familiar, such as small windows, privacy protection, etc., not much to say, simply talk about the display mode of the machine.
Redmi K50 supports 2K resolution and 120Hz refresh rate at the same time, color style support customization, there are a variety of modes to choose from, and true color display, can be adjusted according to their own suitable look and feel color.
Sure enough, this version of the built-in application still has ads, such as weather, calendar, etc., fortunately can be manually closed, there is not much to say, I hope that it will not be opened 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, the first time equipped with MediaTek Tianji 8100 processor, equipped with a full version of LNDDR5 memory + upgraded version of UFS 3.1 flash memory, support for atomic memory and IO Turbo, improve the background residency capacity and file copy speed, which is indeed a more obvious improvement.
Then look at the Tianji 8100, using TSMC 5nm process, the CPU is composed of four 2.85GHz Cortex-A78 large cores and four 2.0GHz A55 energy efficiency cores, which is still armv8 instruction set.
In terms of GPU, Tianji 8100 integrates six-core Arm Mali-G610, GPU frequency has not yet been announced, but compared to Tianji 8000 increased by 20%, in addition, APU is composed of two performance cores and 1 general core, while the frequency is 25% higher than Tianji 8000, equipped with HyperEngine 5.0 game optimization engine, supporting Tianji open architecture, providing higher flexibility for device manufacturers to customize the differentiation functions of high-end 5G smartphones.
On paper, Tianji 8100 belongs to the sub-flagship level, similar to the Snapdragon 870, compared to the latter's A77 core, Tianji 8100 has CPU advantages, focusing on the gap between Mali-G610 and Adreno 650, the specific running scores are as follows.
After actual testing, Redmi K50 Antu rabbit running scored 846787, it was indeed shocking, at this time I found that the target of Tianji 8100 does not seem to be Snapdragon 870, but the flagship Snapdragon 888, and the six-core Mali-G610 can have such a powerful performance. Simple comparison, to the existing Snapdragon 870, Snapdragon 888 models at hand, to see the advantages and disadvantages of Tianji 8100, note that it is only a model with the same price, not a flagship.
First look at the running score, the three mobile phones in the same environment, Tianji 8100 has a better running performance, and then the Snapdragon 888 model, Snapdragon 870 model.
Compared with the sub-score, the CPU performance of the Tianji 8100 is a small advantage ahead of the Snapdragon 870 and behind the Snapdragon 888, because the Cortex X1 core has higher performance performance, but overall, the performance of the four A78 cores is smooth enough to run mainstream games.
In terms of GPU, Tianji 8100 performance is quite strong, breaking through 300,000, almost can be said to be far ahead of Snapdragon 870, followed by Snapdragon 888, although there is a gap, but not large, as a sub-flagship, Tianji 8100 is currently the highest performance, there is no one.
Just looking at the running score doesn't seem to be too much of a surprise? Then power consumption and heat, Tianji 8100 can definitely be called the level of the gods, to see the actual game performance.
- "Glory of Kings"
Game fps
Fuselage temperature
"Glory of the King" opens the 120 frame mode, can completely keep the full frame running, during the frame drop is to reopen a game, the loading process of dropping frames is a normal phenomenon, surprisingly the game 30 minutes, Redmi K50 back cover maximum temperature of 40.6, the average temperature is only 36.6, handheld almost can not feel the heat, once suspected that there is no high frame rate turned on, until the frame rate curve measurement shows the whole process of 120 frames, it is really shocking, I can understand, and greatly shocked.
- "Original God"
Then there is "Original God", the early stage can also be stabilized to 60fps, the follow-up fuselage heat began to drop the frame 45fps, but according to the frame rate curve is wavy, the reason is to run the map and fight monsters, if the monster will drop the frame to about 45, the running map is to maintain about 50, compared to directly lock to 45 is better.
In terms of heat, the maximum temperature is 44, the average temperature is 39.1, in view of the performance of "Glory of the King", this temperature is somewhat high, and after many attempts, it can be concluded that the medium load scenario, Tianji 8100 has excellent, excellent power consumption performance, in the case of high load, Tianji 8100 still has heat, but in front of Snapdragon 888, this heat is not worth mentioning.
4. Video and photography
In terms of imaging, the Redmi K50 rear is 48 million pixel main camera (IMX582, OIS) + 8 million pixel ultra-wide angle + 2 million pixel macro, this combination of daily scanning code is enough, more conscientious is equipped with optical image stabilization, after all, the screen, processor has accounted for a lot of cost, this cost-effective camera shrinkage is inevitable.
Before the sample, it should be noted that the continuous cloudy weather and haze in the local weather affect the purity of the picture, and it is a engineering opportunity, which does not represent the final imaging.
Tall building (default 12MP f/1.8 ISO-56)
High-rise building (2X crop main camera default 12MP f/1.8 ISO-56)
High-rise building (ultra-wide angle 8MP f/2.2 ISO-50)
Plants (main camera macro 12MP f/1.8 ISO-312)
Plants (main camera macro 12MP f/1.8 ISO-326)
Coffee beans (macro 2MP f/2.4 ISO-200)
Imaging details are good, daytime scene noise control is also the mainstream level, this CMOS advantage is to shoot close-up, especially bokeh details, natural transitions, flower color reproduction is precise, there is no color cast, but the macro lens is somewhat unsatisfactory, and it is necessary to adjust the angle many times to shoot a clear macro.
Fifth, battery life and charging
Redmi K50 is equipped with a 5500mAh battery, note that it is a piece, not a dual battery, is currently rare large battery, with Tianji 8100 low power consumption how? Take a look at the measured data, and routinely use the Antutu stress test function to carry out super power consumption test.
Stress test is a function built into the Antutu evaluation, by performing high load calculations to test the stability of equipment performance, the CPU needs to carry out a lot of calculations, so the power consumption is greater than video, daily use and other scenarios, open 2K + 120Hz high brush mode.
Under the super power consumption test, Redmi K50 insisted on 240 minutes, which is really a surprise, comparable to the entry model with the main long endurance, to know that this is still in the 2K resolution scene, it is expected that the 1080P mode has a longer endurance performance.
Compared with a model equipped with Snapdragon 870+4500mAh is 170 minutes, K50 is 240 minutes, which is the longest model in the current pressure test of the new machine, on the one hand, because of the 5500mAh large battery, on the other hand, the low-power advantage of The Tianji 8100.
It should be noted that this result is based on the CPU has been in full load to obtain, considering our daily use and light screen time, so this data should be converted into multiples, it is concluded that Redmi K50 has more than 8 hours of continuous use time, note that it is continuous use, not daily screen off, back to messages, etc.
In terms of charging, the Redmi K50 supports 67W wired fast charging, let's see how fast it goes.
After practical testing, the Redmi K50 took 50 minutes to charge to 100%, of which 10 minutes were charged with 44% of the charge and 30 minutes were charged with 75%, which is a normal charging speed for a 5500mAh battery.
6. Summary
Redmi K50 is a product that exceeds expectations, is another benchmark at the same price, especially the front 2K high brush screen and Tianji 8100, interpreting what is the ultimate cost performance, as well as 5500mAh large battery long endurance, I have to say that this very cost-effective product is only Made by Redmi.
Cost-effective models will inevitably have defects, such as the rear camera is still 48 million pixels three cameras, but added OIS optical image stabilization, it does not appear so sincere, this is the trade-off made by Lu Weibing, at present, it is indeed accurate, the user wants to give, even beyond expectations.
Of course, if a product only has enough flash points, it can not cover up its shortcomings, but on this basis to the starting price of 2399 yuan, the nature is different, 2K high brush screen, 67W fast charging, can be called the flagship performance mid-range power consumption of Tianji 8100... Together, these combinations can predict that the aircraft will once again hit tens of millions of sales.
Lu Weibing once said in an interview that the people who make our products are nothing more than making choices for users, looking at the entire product line of the K series, Lu Weibing is undoubtedly a product manager with quite accurate insight, which is inseparable from the long-term interaction with netizens on Weibo, of course, K30 Pro.
Finally, talking about Redmi, there is no doubt that the brand has successfully taken over the cost performance of Xiaomi, with this, the K series has become another product line of Redmi with tens of millions of sales, stabilizing the cost-effective moat.
Somehow, seeing the K50 series, always think of last year's Xiaomi spring new product conference, the theme of this conference is only four words, think about it, may be because of the tens of millions of sales of the K series, so as to continuously give millet blood transfusions, is its impact on the high-end of the guarantee, but also the foundation, in this cycle, to create endless life.
Now Redmi, let me see the millet of many years ago, sincere and firm, believe, forward, and run forever.
