Redmi K40 Pro experience: 2799 RMB cost-effective mobile phone, where has it been upgraded

Before the release of redmi K40 series (hereinafter referred to as K40 Series), redmi’s marketing team publicized the slogan of “flagship weldman”. However, this is not surprising. We have seen its ambition since the leapfrog configuration of the k30s supreme commemorative version which was launched at the end of last year.

The K40 series released in the early spring of this year went a step further. The initial configuration was to bring the Qualcomm snapdragon 870 to play together. When the audience of the conference saw the price was announced, Qi Qi said in the barrage that it was too fragrant.

I also watched the whole live broadcast of the red rice press conference. Just after this live broadcast was interrupted, a friend from the other end sent a message asking for help in advance purchase. Of course, he did not know at this time. I was replying to his message in K40 pro.

From that day on, K40 Pro has become my main engine. Here is what I want to say to my friend about all aspects of K40 pro.

White as snow

The K40 Pro obtained this time is a white version. The official name for it is “clear snow”. It has no texture. It is a common white. When the light shines on it, it will become a light white. It looks like soft cotton snow. AG glass panel with fine sand blasting technology, attracting users to play with it.

Although its color is so simple, it is one of the four colors in the K40 series that I like the most.

The design of the back of the mobile phone is so simple that it has a redmi logo and a stacked rear view module. The terraces are generally stacked. When playing horizontal screen games, the finger belly is just placed outside the rear camera module, and the two sides of the game are held symmetrically for better hand feeling.

When I hold the K40 Pro normally, I feel a little wider on the whole. Maybe it is because I am used to the feel of the iPhone 12 Mini. It took a long time for me to get used to it when I first replaced the main engine with the former.

Turn the K40 pro from the back to the front, with the middle frame made of plastic for transition. The sandwich sandwich design of the middle frame, namely, three layers of “bright surface, frosted surface and bright surface”, improves the hand feel and the appearance, so that I repeatedly confirm that it is actually plastic at the first time.

The buttons of the whole machine are set on the right side of the body, which are volume key and screen lock key. The lock screen key also takes into account the function of fingerprint identification. The unlocking reaction is quick, almost touch and open, and there is no redundant animation effect. It is the purest and fastest.

According to my own measurement, no matter it is sweaty or slightly wet, it will not affect the function of the side fingerprint unlock button. Compared with other mobile phones on the market that use off screen fingerprint technology, I just want to say a word to the physical fingerprint unlock key: ginger is still old and spicy.

At the top is the horn hole, one of which is sealed. It is hard to find out if you don’t look closely. There is an infrared remote control module hidden here; the bottom is SIM card slot, USB type-C interface and horn hole.

The thickness of the whole machine is 7.8mm The weight is 196g It is 20g lighter than k30s.

The overall shape of this generation of redmi mobile phones this year returns to rationality. There are no redundant elements. Practicality is paramount. Do you think it looks good?

The screen stacking is a little hard

Before the launch, the K40 series emphasized its screen quality. After getting started, I found that the screen was “needle not poked”.

There is one on the front of the phone 6.67 inch Samsung E4 AMOLED direct screen This size is almost the same as a big Mac in today’s mobile phones on the market. It may also be the best color display screen in 2000 yuan mobile phones.

Redmi K40 Pro experience: 2799 RMB cost-effective mobile phone, where has it been upgraded

However, the resolution of such a large screen is only 2400 × 1080, which makes the display delicate and disappointing.

The display effect of K40 Pro can definitely meet the needs of most consumers. However, compared with other mobile phones, it can be observed that K40 Pro has jagged edges in text or graphic display. Although it is necessary to make the eyes close to the screen, it can still be seen that this screen has its own preference.

Give up higher resolution, take sincere color.

Because E4 display material has the characteristics of higher brightness, lower power consumption and more accurate color, K40 Pro has the strongest display quality in series.

Dci-p3 wide color gamut, hdr10 + high dynamic range, MEMC dynamic compensation, 1300 nits peak brightness, 8bit color depth, true tone true color display And other technologies are collectively displayed on this screen.

It is also because K40 is extremely stacked on screen technology, which helps it win the displaymate a + rating. The delta e of color difference is about 0.35, which means that the color deviation is smaller.

The front and rear ambient light sensors make the automatic brightness adjustment, a long-standing function, no longer “mentally retarded” and bid farewell to the embarrassing situation of “dark surroundings and bright mobile phones”.

Highest screen The display frame number is 120Hz , highest The touch sampling rate is 360hz 。 The former makes the user’s picture more fluent and natural; the latter makes the operation more precise and smooth in the game, similar to that in the mouse Rate of return The higher the value, the more accurate and fast the operation is.

The impact of high refresh rate on user experience is unnecessary.

This is a technology that can’t be used back. Undoubtedly, it took only two or three years to develop from the bonus item of flagship mobile phone to the standard configuration item of Android mobile phone. It also reflects the user’s love for it, which is far higher than other display technologies.

Since the birth of smart phones, we have been spending more time on the screen of mobile phones. Therefore, redmi’s product strategy of “good screen” is worthy of follow-up by other manufacturers.

This is probably the first half of the flagship configuration

The slogon of redmi K40 series is “a little tough real flagship”. Its screen is hard and its performance is also fierce.

The whole series adopts 8-character high-pass chips. The K40 has been carrying the snapdragon 870 since its inception. It seems that it is the mission of the K40 series to knock down the price of the flagship.

And the K40 Pro I have in hand, and the K40 PRO + which will be launched in the future, are both used Snapdragon 888 SOC Kryo 680 architecture, 5nm process, the highest frequency of 2.84ghz.

8GB 3200mhz lpddr5 running memory, 256gb ufs3.1 storage, is the top configuration version of K40 pro, the price is 3299 yuan.

support Wifi6 enhanced and Bluetooth 5.2 It should be up to date.

In the past few days, we have not encountered the ceiling in terms of performance, but in terms of basic communication and Bluetooth, unexpected situations have occurred.

On the day when K40 Pro was just handed over, the signal dropped to 3G and could not be connected to the network. After the restart, the problem was solved, and it didn’t happen again in the next few days.

In addition, when I went to the high-speed railway station with my wireless headset on, my right ear headset was disconnected, but it recovered automatically after a period of time. In order to eliminate the problem of headphones, I connected the headset to another mobile phone. The environment was the same, and there was no disconnection within half an hour. Maybe the Bluetooth module used by K40 Pro has insufficient filtering efficiency or computational performance in complex signal environment.

It is hoped that redmi’s subsequent firmware upgrade can completely solve these two problems.

Since the performance of K40 Pro is so strong on the book, it is of course necessary to test the game with “original God”, “peace elite” and “call of duty”.

The original God of “equality of all beings” did not disappoint me. No matter what the image quality mode is, as long as you turn on 60fps, the number of frames will drop immediately 30-60fps There is no regular fluctuation between them.

Redmi K40 Pro experience: 2799 RMB cost-effective mobile phone, where has it been upgraded

The performance of K40 pro in the two games of peace elite and call of duty is quite consistent. The frame rate mode remains the highest, and the picture quality is adjusted from high to low, and the frame number is basically stable at the highest point (59.8-60fps).

This is also proved in the actual play. It seems that the performance tuning of K40 Pro can be comparable to some flagship game phones. Unfortunately, the two shooting games tested at present have not opened the 90fps frame rate mode. We hope that we can keep up with it in the future.

The “4D game vibration 2.0” promoted by K40 Pro has a general experience, and the x-axis linear motor has not brought the expected vibration experience, which is slightly weak and loose.

Unexpected endurance performance

The 7.8mm K40 Pro carries a 4520mah battery, which can be called a master of space management. Combined with the extreme control of MIUI 12 on power consumption, K40 Pro has excellent endurance performance.

I’m on Sunday 8:08 am Pull off the charging cable of K40 pro, and go out at full power until 8:09 PM When we get home, we have the electricity left 23% 。 During this period of time, there is no less play, no less shooting, and you can still get 20% of the battery back home.

The random bonus is, 33W It can be charged from zero to 63% in half an hour, 96% in one hour and fully charged in one hour and three minutes. In addition, K40 Pro supports QC3+/PD3.0 Fast charging protocol means that it can achieve faster charging speed than the original one.

The protective cover is provided with a waterproof plug at the charging port

By the way, there is no wireless charging function in all K40 series products.

Take a picture and make a short board

K40 Pro back shot three lenses 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 megapixel long focus macro lens.

As an ordinary consumer, I usually use the main camera. Thanks to the large aperture, I can guarantee a high amount of light. In the face of the recent cloudy days in Guangzhou, I can still take clear pictures of street scenes and objects, and the color performance is more natural and eye-catching. I can share the daily life, and there is no big problem in sending friends or microblogs. However, after the original picture is enlarged, it can be seen that the painting is obvious.

In the night scene mode, K40 Pro has a slow imaging speed, and it is difficult to guarantee the film production rate by holding it. If you are a ruthless iron hand, you can still take a satisfactory night scene picture under all smooth conditions.

Macro lens is more interesting. It can take clear details of objects at a very close distance. The distance between the lens and the object can be successfully focused at a distance of 2-3cm. In this mode, the camera can take interesting pictures and see a different world with the help of mobile phone lens.

Now it is only 3cm away from the flower

The overall shooting quality of K40 Pro can only be said to be in order, and the performance of skipping the level was not seen.

In front of the screen, performance and camera, K40 Pro embraces the first two, which is equivalent to making friends with most users. If you have higher requirements for taking photos, you can wait for K40 PRO + with Samsung hm2 sensor.

Summary

These are some of my experiences and feelings. K40 Pro shows the quality of a “hexagon warrior” and has almost completed all parameters. Regardless of the user’s age, demand, it can show the side that touches you.

When you enjoy the ultimate experience of being close to the people, please accept its minor defects. If you can understand and accept it. Then, for you, it is worthy of its status as a “flagship weldman”.
