Before the release of the Redmi K40 series (hereinafter referred to as the K40 series), Redmi’s marketing team announced the slogan “Flagship Doorman” to the world. However, this is not surprising. We started from the K30S Extreme Commemorative Edition that was launched at the end of last year. The leapfrog configuration first saw its ambitions.
The K40 series released in the spring of this year went a step further. The starting configuration was to bring the Qualcomm Snapdragon 870 to play with, so that the audience at the press conference, when they saw the price being announced, all shouted out in the barrage.
I also watched the entire Redmi conference live broadcast. This live broadcast has just been interrupted, and a friend sent a message to help pre-order together. Of course, he still doesn’t know at this time. I am replying to his message on K40 Pro.
Since that day, K40 Pro has become my main machine. Below is what I want to say to my friend about all aspects of K40 Pro.
White as snow, it feels brilliant
The K40 Pro I got this time is a white version. The official name is “Qingxue”. It has no texture, just ordinary white. When the light shines on it, it will appear a pale white. It’s like soft snow. The AG glass panel and the delicate sandblasting process attract users to play with it.
Although its color scheme is so simple, it is my favorite among the four color schemes of the K40 series.
The design of the back of the mobile phone is concise to the extreme point, a Redmi logo, and stacked rear camera modules, terraces are generally stacked. When playing the horizontal screen, the finger pads are just placed outside the rear camera module, and the two sides of the game are held symmetrically, which makes the hand feel better.
When I hold the K40 Pro normally, it feels slightly wider overall. Perhaps I am used to the feel of the iPhone 12 mini. When I first changed the main machine to the former, it took a long time to get used to it.
Flip the K40 Pro from the back to the front, with a plastic middle frame in the middle for transition. The middle frame uses a sandwich design with three layers of “bright surface-matte-glossy surface”, which enhances the hand feel and enhances the look and feel, so that I repeatedly confirmed the first time I got it, I couldn’t feel that it was actually plastic.
The buttons of the whole machine are set on the right side of the fuselage. They are the volume button and the lock screen button. The lock screen button also takes into account the function of fingerprint recognition. Purely fast.
According to my actual measurement, whether it is sweaty or slightly wet, it will not affect the function of this side fingerprint unlock button. Compared with other mobile phones on the market that use under-screen fingerprint technology, I just want to say a word to the physical fingerprint unlock key: Jiang is still hot.
The top is a speaker hole, one of the holes is sealed, it is difficult to find if you don’t look closely, the infrared remote control module is hidden here; the bottom is the SIM card slot, the USB Type-C interface and the speaker hole.
The thickness of the whole machine is 7.8mm, The weight is 196g, 20g lighter than the K30S Extreme Commemorative Edition.
The overall shape of this generation of Redmi phones this year is back to rationality, there are no extra elements, and practicality is paramount. Do you think it looks good?
Screen stacking is a bit ruthless
As early as before the press conference, the K40 series emphasized its screen quality. After getting started, I found that the screen was “no needle poke”.
One piece on the front of the phone 6.67-inch Samsung E4 AMOLED straight screen, This size is almost the existence of a Big Mac in today’s marketed mobile phones, and perhaps the best color performance screen in the 2000 yuan mobile phone.
However, with such a large screen, the resolution is only 2400×1080, which makes it a little disappointing for the exquisite display.
The display effect of K40 Pro can definitely meet the needs of most consumers, but compared with other mobile phones, you can still observe the K40 Pro. Whether it is on the text or graphic display, the edges will be jagged, although the eyes should be close to You can find it almost to the extent that it is pasted on the screen, but it still allows people to see that this screen has its own preferences.
I gave up the higher resolution and adopted the true colors.
Due to the higher brightness, lower power consumption, and more accurate colors of the E4 display material, the K40 Pro has the strongest display quality in the series.
DCI-P3 wide color gamut, HDR10+ high dynamic range, MEMC dynamic compensation, 1300 nits peak brightness, 8bit color depth, True Tone true color displayAnd other technologies are collectively unveiled on this screen.
It is also because the K40 has the ultimate stacking material on the screen technology, which helped it win the DisplayMate A+ rating. The color difference Delta E is approximately equal to 0.35, which means that the color deviation is smaller.
The two ambient light sensors on the front and rear automatically adjust the brightness of this long-existing function, making it no longer “mentally retarded”, saying goodbye to the embarrassing situation of “the surroundings are very dark and the phone is bright”.
The highest screenDisplay frame number is 120Hz,highestTouch sampling rate is 360Hz.The former makes the picture that users see more smooth and natural; the latter makes the operation more precise and smooth in the game, similar to the mouseresponse rateThe function of the parameter, the higher the value, the more accurate and quicker the operation is.
The impact of high refresh rate on user experience is no longer necessary.
This is a technology that you can’t go back after you have used it. Undoubtedly, it only took two or three years to develop from the bonus items of flagship phones to the standard items of today’s Android phones, which also reflects the users’ Its popularity is much higher than other display technologies.
Since the birth of smartphones, the time we spend on mobile phone screens has increased unabated, so Redmi’s product strategy of “good screen” this time is indeed worthy of follow-up by other manufacturers.
This is probably the flagship configuration in the first half of the year
The Slogon of the Redmi K40 series is a “a bit ruthless flagship”, with a ruthless screen and a ruthless performance.
All series use 8-letter Qualcomm chips, K40 is equipped with Snapdragon 870 from the beginning, desperately knocking down the price of the flagship machine, seems to be the mission that comes with the K40 series.
And the K40 Pro I have, and the K40 Pro+ that will be launched in the future, both useSnapdragon 888 SoC, Kryo 680 architecture, 5nm process technology, clocked at up to 2.84GHz.
8GB 3200MHz LPDDR5 running memory, 256GB UFS3.1 storage, is the top version of K40 Pro, priced at 3299 yuan.
stand by WiFi6 enhanced versionwithBluetooth 5.2, And everything is up to date.
In the experience time of the past few days, I haven’t encountered the ceiling in terms of performance, but in terms of basic communication and Bluetooth, unexpected situations occurred.
The day when the K40 Pro was first received, I encountered a situation where the signal dropped to 3G and the network could not be connected. The problem was solved after restarting, and I did not encounter it again in the next few days.
In addition, I wore a wireless headset to the high-speed railway station and encountered a disconnection of the right ear headset, but it automatically recovered after a period of time. In order to eliminate the problem of the headset, I connected the headset to another mobile phone. The environment remains the same, and there is no disconnection within half an hour. Perhaps it is the Bluetooth module used by the K40 Pro. Under the environment, the filtration efficiency or computing power performance is insufficient.
I hope that Redmi’s subsequent firmware upgrades can completely solve these two problems.
Since the performance of the K40 Pro on the books is so strong, of course, the game test link is indispensable, and the “Original God”, “Peace Elite” and “Call of Duty” are selected for testing.
The original god of “all beings are equal” really did not disappoint me. No matter what image quality mode it is in, as long as 60fps is turned on, the frame rate will drop immediately. 30-60fps There are irregular fluctuations between.
The performance of K40 Pro in the two games of Peace Elite and Call of Duty is quite the same. The frame rate mode remains the highest, the picture quality is adjusted from high to low, and the frame rate is basically stable at the highest point (59.8-60fps). ).
This is also proved during actual play. It seems that the performance tuning of K40 Pro can be comparable to some flagship gaming phones. Unfortunately, the two shooting games currently tested have not opened the 90fps frame rate mode. I hope that we can keep up with it in the future.
The “4D Game Vibration 2.0” advertised by K40 Pro, I personally feel that the experience is average, and the X-axis linear motor does not bring the expected vibration experience. The overall effect is slightly weak and loose.
Unexpected battery life
The 7.8mm thick K40 Pro is equipped with a 4520mAh battery, which can be called a master of space management. Coupled with MIUI 12’s extreme control over power consumption, the K40 Pro has a good battery life.
I’m on sunday8:08 amUnplug the charging cable of the K40 Pro at time, and leave the house fully charged until8:09 p.m.Back home, battery is left 23%. During this period of time, I didn’t play less, didn’t take less shots, and I could return home with 20%+ power remaining.
The random gift is,33W The fast charging source can charge from zero to 63% in half an hour, 1 hour to 96%, and full charge in 1 hour and 03 minutes.In addition, K40 Pro supports QC3 + / PD3.0 The fast charging protocol means that it can achieve a faster charging speed than the original one.

By the way, all K40 products that have been released so far have no wireless charging function.
Take a picture as a short board
The three rear cameras of K40 Pro from top to bottom are:
Sony 64-megapixel IMX686 sensor main camera, 1/1.7″ area CMOS, f/1.89 aperture;
8-megapixel ultra-wide-angle lens, 119° field of view, f/2.2 aperture
5 million pixel telephoto macro lens.
As an ordinary consumer, I usually use the main camera most often. Thanks to the large aperture, it can guarantee a higher amount of light. In the face of the recent cloudy sky in Guangzhou, I can still photograph the street scenes and objects clearly, and the color performance is relatively natural. It’s eye-catching, it’s used to share life’s bites, and it’s not a big problem to post to Moments or Weibo, but you can still see obvious smearing after the original image is enlarged.
In the night scene mode, the imaging speed of the K40 Pro is slow, and it is difficult to guarantee the filming rate when holding it. If you are a ruthless iron hand, you can still take satisfactory night scene photos under all smooth conditions.
The macro lens is more interesting. It can capture clear details of the object at a very close distance. The lens and the object can be successfully focused at a distance of 2-3 cm. In this mode, the viewfinder can be properly viewed and interesting pictures can be taken with the help of a mobile phone. The lens sees a different world.
▲ At this time, it is only 3 cm away from the flowers

The overall shooting quality of the K40 Pro can only be said to be quite satisfactory, and I have not been able to see its leapfrog performance.
In the face of the three major elements of screen, performance, and camera, K40 Pro embraces the first two, which is equivalent to showing good to most users. If there are higher camera requirements, you can wait for the K40 Pro+ with Samsung HM2 sensor.
summary
The above are some of my experience. K40 Pro shows the qualities of a “hexagonal warrior”, and almost all the parameters are filled. Regardless of the age of the user, the level of demand, it can show the side that impresses you.
When you enjoy the ultimate experience that it brings to you, please accept some of its innocuous minor faults. If you can understand, you can accept it. So, for you, its identity as a “flagship doorman” is well deserved.
