The Redmi K50 Premium Edition was released on August 11. It has a new ID design, a new 1220p screen (with 1920Hz high-frequency PWM dimming), and a new Samsung HM6 sensor, which has pushed the price of Snapdragon 8+mobile phones down to 2999 yuan. The top 12+512 launch also "only" costs 3699 yuan.
What is the experience of purchasing 1220p screen, HM6 and Snapdragon 8+for 2999 yuan? Now let's take a look at this new Snapdragon 8+price butcher.
The Redmi K50 Premium Edition is 8.6mm thick, 202g, AG glass+plastic middle frame+underscreen fingerprint. Xiaolong 8+, 6.67 inch 120Hz 2712x1220 of Huaxing/Tianma, similar drill row, 1920Hz PWM dimming. 108 million HM6 (64 million HM6 μ m. F1.65+OIS)+800W ultra wide angle. 5000mAh battery+120W fast charge.
The first 8+128 version is 2999 yuan, the 8+256 version is 3099 yuan, the 12+256 version is 3399 yuan, and the 12+512 version is 3699 yuan.

Xiaomi, a 120W fast charging head with the model of MDY-12-ED, has been used since Xiaomi 10 Ultra, the first 120W fast charging head in 2020. If there is no accident, it should already be the 120W fast charging head with the largest shipment.
Our ice blue is our most recommended color. The back cover design inherited from the "friends" is really Beautiful, pleasing, harmonious AG glass and metal will never go out of style (metal camera matrix, plastic middle frame).
The middle frame has wire drawing effect, and the top and bottom surfaces have bright surface treatment, which is inherited from K50/K50 Pro. However, the middle frame and back cover of the Redmi K50 Premium have larger curved surfaces, making it more rounded and comfortable to hold. The disadvantage of bright blue is that the speaker and card slot openings will discordantly reveal a lighter plastic primary color.
In addition, there is the "K50 Champion Mercedes AMG PETRONAS Formula One Team Summer Edition" with a very long name, which may be the longest product name in the history of mobile phones (a string of capital letters in English that cannot be understood means Petronas). The iPhone 13 Pro Max 1TB Yuanfeng Blue National Travel on our hands was launched for the first time, duty-free for non Hainan, fined 300000 yuan for early activation, purchased an additional year of Apple Care+, a one-time full version, and a special version with three special tickets.

The screen frame control and size of K50 Premium are close to those of K50, and the chin control is still slow. The 2.5D radian of the screen is very small, the screen washer is straighter than K50, and the side returns slightly.
old buck X-axis vibration motor of 0809 , the vibration feeling is tight and the strength is weak. 1012+1216 dual speakers, good external placement The sound quality of the lower speaker is very good, and it is far away from the upper speaker. The overall stereo is relatively balanced, and it is more careful than many 5000 yuan flagship speakers.
After K30, the invisible screen fingerprint returns, Short focal fingerprint , the position is lower, and the speed and recognition rate are normal.
"1.5K screen": 1920Hz high-frequency PWM dimming!
The default touch sampling rate of the system is 240Hz, and 480Hz in the game. Quickly click the screen password and it won't stick. Even the escape of an antique temple can trigger 480Hz.
Gamut, gray scale, color quasi objective test ↑
The Redmi K50 Premium is a 6.67 inch 120Hz central perforated straight screen, 2712x1220446ppi, 480Hz touch sampling. It is supplied by Huaxing Pearl 2.0/Tianma windmill, both of which are similar drill rows, and are respectively Huaxing C4/Tianma T7 light-emitting materials, claiming to surpass Samsung E4. 10bit, 12bit, factory color calibration.
Officially, "1.5K/1220P" is not a transition plan, but a long-term evolution strategy. 2K and 1.5K will be used in different product lines at the same time. There is an interesting data in the official data that the fixed brightness maintains the brightness of the screen, and the attenuation to 95% is usually 300 hours. However, it improves the BSM design to extend it to 400 hours, which can slow down the burning of the screen, but the time is limited, so it can not be tried.
@The screen code rule summarized by Tiantianzuo Luoshi: 36 Tianma, 37 Shenchao, 38 Samsung, 41 Vicino, 42 CSOT, 43 JDI.
Subpixel arrangement (Tianma windmill) ↑
@NavisLi has the Chinese Star version on hand, but this one on our hand is the same as that of @ WHYLAB and @ Tiantianzuo Luoshi.
The measured peak full white energy of the Tianma screen is more than 900 nits, and the color accuracy is close to that of other K50 family devices. The fineness and sub-pixel rendering are all OK, which is a good comment.
Of course, the core is 1920Hz high-frequency PWM dimming, comfortable! Previously, 1920Hz dimming was mainly used for glory, while Huawei used 1440Hz PWM.
Redmi K50, K50 Premium, K50 E-sports ↑, dimming mode switching interval (pay attention to the position of the brightness bar). The Redmi K50 Premium is a mobile phone that does not need the LF flash mode Not only is the dimming more frequent, but also the brightness of switching dimming mode is lower than that of the other two, which is good for civilization and setting!
Redmi K50, K50 Premium, K50 E-sports ↑
Brightness: Top stream level of domestic screen. The full white excitation brightness exceeds 900 nits, which is higher than the full white excitation brightness of the Samsung E4 screen. However, it does not have the common feature of OLED that "brightness increases as the display area becomes smaller". The brightness of local white will become lower, so the local peak will not win the Samsung E4 screen.
Uniformity: When the center is 503 nits, the brightness of the four corners is 502/503/511/508, and the brightness consistency is better than the current E5 screen (the latter has higher brightness, and the absolute value of the brightness difference will be greater).
Color accuracy: The default color temperature is slightly cooler, the P3 color accuracy of the default mode is even higher than K50/K50 Pro, and the primary color mode (sRGB) is slightly weaker, but the overall performance is good.
Viewing angle: The main difference between the Redmi K50 premium version of the Tianma screen and the top Samsung E4 screen is the color consistency at a large angle, which tends to be yellow. Personally, it is more obvious than the Samsung E5 screen.
But reasonable, Domestic screens have made rapid progress and will listen to consumer feedback (e.g High frequency PWM adaptation), It specializes in the treatment of exotic and difficult diseases such as unstable supply/high price of foreign brands, Like the domestic screen 。
For the problem of precision, the official "1.5K screen" is 2712x1220. It is difficult to understand the mathematical relationship using the mathematical knowledge of the second grade.
The actual translation is between 2K and 1080P screens. The number of pixels is closer to 1080P screens, and there is still a certain gap with the common 2K screens. Here is a summary, arranged by the number of pixels. Huawei and Glory are the first manufacturers to touch Apple on screen ppi (fineness):
Xiaomi 12S Ultra/12S Pro/12 Pro, 3200 * 1440=4608000522ppi
Redmi K50/K50 Pro， 3200*1440=4608000，526ppi
Huawei Mate 40 Pro, 2772 * 1344=3725568456ppi
iPhone 13 Pro Max， 2788*1284=3579792 ，458ppi
Redmi K50 Premium, 2712 * 1220=3308640446ppi
Huawei P502700 * 1224=3304800458ppi
Huawei P50 Pro, 2700x1228=3315600450ppi
Glory 60 Pro, 2652 * 1200=3182400429ppi
Huawei P40 Pro, 2640 * 1200=3168000441ppi
iPhone 13， 2532*1170=2962440 ，460ppi
One Plus Ace Pro, 2412 * 1080=2604960394ppi
Reasonably, 1220P is more refined than 1080P, It is a dessert choice, balancing cost, power consumption and fineness It is hoped that this wave can accelerate the obsolescence of 1080p OLEDs.
1080p antique LCD screens used by human beings in 2014 can be hung with great precision, and LCD will never be a slave! LCD was destroyed by 1080p OLED, which is a disgrace in LCD history.
Visual perception under translation: From the 2K screen to the 1220P of the Redmi K50 premium version, you will feel a little more grainy. You will have a moment of doubt, and you need to get closer to it for confirmation. From 2K to 1080P, it is "full and big fruit", without any hesitation, and the judgment process does not even need 0.022434653 seconds.
Other objective tests
Snapdragon 8+, which will soon become an old friend, has nothing to say, the Redmi K50 Premium CPU multi-core performance is released rapidly, and GPU and flash memory perform normally.
3DMark Wild Life Extreme consecutive runs ↑
The default mode of Redmi K50 Premium can reach 3+2.65+1.8 in the game and 2.8+2.5+1.8 in daily life. The performance mode can always maintain 3+2.7+1.8, It's easy to open all 8 cores when you open the app or reload, which is already a "game phone" 。
But its strength lies in the fact that Before overheat protection, it always tries to run to the preset high frequency Therefore, the continuous test results of 3DMark Wild Life Extreme are very stable, even when the 3DMark toaster comes out, it can be 2.36+1.9+1.8, which is a tuning that I dare not think of before.
The surface temperature control line is about 50 degrees, and the overheating protection will be triggered if it is higher. Parts related to machine safety are still conservative ↑
The price of this kind of adjustment is that the room temperature is 25 degrees, the screen brightness is 200 nits, 3DMark Wild Life Unlimited and Wild Life Extreme Unlimited tests will be overheated and unable to run 。 Ordinary models will reduce the frequency, so they can run the test (Snapdragon 8+models have a stability between 60% and 92% in Wild Life Extreme Unlimited).
After a vigorous tuning, the power consumption of the Redmi K50 Extreme Edition will increase from 4% in the normal mode to 6% when watching the station B for half an hour in performance mode+200 nites brightness. According to UC style, it should be: shock! Power consumption will increase by 50%! Therefore, it is recommended to use the normal mode. Snapdragon 8+now has sufficient performance.
Personally, I prefer this "Conservative temperature control, but crazy running before temperature control" It has a good tuning style and gives priority to the performance release. It is a good candidate for playing games with the heat sink. The first task of mobile phones that mainly promote games is to give performance, and power saving should not be their goal.
In fact, there are fewer small Cartons in the Redmi K50 Ultimate than other normal Snapdragon 8+models in the Original God, and they are indomitable before overheating protection, while the conservative overheating protection will not let you injure the machine by mistake, good.
This generation of Snapdragon 8+model, even the model with the worst heat dissipation, can barely conquer the original God by virtue of the SoC energy consumption ratio. As long as the performance requirements of Yuanshen 3.0 are not significantly improved, next year's mainstream toaster software may be changed to Bright Mountains.
The Redmi K50 Premium Edition uses a 5000mAh single cell, 200 nit brightness, and after 30 minutes of Elite for Peace (HDR HD+extreme frames+anti aliasing), 30 minutes of 1080P video playback at station B, 30 minutes of short microblog video, 30 minutes of Wi Fi and 5G surfing, and a total of 2.5 hours of endurance testing, the remaining power is 76%. With higher screen resolution, A small loss to the real me GT2 master exploration version, a small victory plus Ace Pro, the performance is good, Tianma will not deceive me 。
25 degrees, 200 nites, 20 minutes of Peace Elite, the highest temperature of Redmi K50 is 39.1 degrees, 1 degree lower than the true GT2 master exploration version, and 2 degrees higher than the conservative iQOO 10 Pro.
Both Redmi K50 Premium and Redmi K50 Pro are 5000mAh single cell+120W+surging P1, and the actual effect is similar. The Redmi K50 Premium Edition displays full charge in 20 minutes and off charge in 21 minutes.
The single core 120W heating is larger than the dual core scheme, and the charging performance of the Redmi K50 Premium Edition will be significantly affected by the ambient temperature, and it can be full of blood at 23 ℃; At 25 ° C, the "thermal frequency reduction" will take about 5 minutes.
Room temperature 23 ℃, full blood status ↑
The room temperature is 25 ℃, and the left hand state ↑
23 and 25 degree charging nodes and power data ↑
Not to mention the familiar MIUI 13, which is a positive dragon 8+blessing. The daily fluency is very good, and the functions are not special.

The camera specification of the Redmi K50 Premium is between the Redmi K50 and K50 Pro. The best way to use the camera is as follows:
Front view 2000W, IMX596, 0.8 μ m，F2.24
108 million, Samsung HM6, 0.64 μ m. 1/1.67 ", 1G+5P lens, F1.65+OIS
Ultra wide angle 800W, Samsung S5K4H7, 1.12 μ m，1/4''，F2.2
200W GC02M1 Macro
The sensor size of Samsung HM6 is between IMX766/HM2 and IMX582, but because the size of unit pixel is small, it will suffer more in theory, so here we find the weak IMX766 for comparison.
Use 2x zoom to see the ultimate discrimination (it will be mixed with the influence of the "rocking music" detail enhancement algorithm)
Although there are Qualcomm and MediaTek's SoC, the algorithm is differentiated according to Sony and Samsung CMOS. Two Sony CMOS mobile phones are obviously stronger, and sharpening algorithm is also very heavy , two high pixel/small pixel Samsung CMOS, but there is no trace of shake music algorithm.

The HM6 of Redmi K50 Premium is small in pixels, but the aperture of F1.65 is difficult to compete with its peers. The actual ISO is often lower than that of competitors, but the film rate is average. When taking photos, you should carefully hold the phone.
and The actual performance of HM6 slightly exceeds that of IMX582 of K50 In the daytime, the analytical power is weak, but it is still slightly stronger than the green factory IMX766 with a broader vision. The night view algorithm of Redmi K50 Premium is stronger than that of its predecessors, and it can almost touch the HM2 of K50 Pro. However, due to hardware limitations, the night view algorithm of Redmi K50 Premium is far from that of IMX766.
The super wide angle is a surprise. The super wide angle of Redmi K50 has an automatic night view. Everyone stands up! The actual weak light performance is far better than the K50/K50 Pro without automatic night view in super wide angle, and slightly weaker than the GT Neo3 (in fact, the latter's night view mode is not active and stable).
summary
Some people may feel sorry for the E-sports version with more detailed workmanship and details. It would be great to change the SoC, but if the surrounding is still the same set, the price will not be reduced to 2999. Some people also think that this configuration is not superior enough, but it does not set a superior price
The K50 Premium is a product adhering to the orthodox thinking of Redmi, and the sword technique is the key to cost control. The resolution of 1220p domestic screen is a little higher than 1080p, but the precision of ppi is just right for dessert, and the power consumption and cost are just right. In front of it, the 2K screen of the K50 seems to be inexperienced and a bit over the top (including effect and price). If you change the K50 to a 1220p or 1080p screen, the price battle force will take off on the spot.
The K50 Premium also tells us that Snapdragon 8+is not cheap. The starting price of Tianji 9000 K50 Pro is the same as that of Tianji 9000 under the condition that the screen and camera have given face. We have to lament that it is too powerful!
If the K50 focuses on the screen and endurance, then the K50 Premium is undoubtedly for performance and game services, just take what you need and leave a way for the K50 Pro. The most cost-effective version must be the 8+256 version with 3099 yuan, and the 12+256 version is conditional. After all, for phones with flagship SoC, memory and capacity are the key factors that determine how long nail users can nail.
