From 1599 yuan, 120Hz screen refresh rate, front dual hole digging screen, 27W fast charging, Sony IMX 686 64 megapixel main camera, Qualcomm Snapdragon 730G, and so on. This is the latest Redmi K30 4G. With the price of mobile phones rising, a burst of fragrance is coming. Is that Xiaomi we are familiar with coming back? No, it's Redmi. We can't wait to see how Redmi K30 4G (hereinafter referred to as K30) actually performs!
appearance
There are three main points in the appearance of K30 this time, the first is the front double hole digging screen, the second is the side fingerprint identification, and the third is the "coin slot" design of the rear camera;
First, let's take a look at the front double hole digging. In fact, when the screen is turned off, the two cameras dig holes separately, not in the shape of the "pill" we saw before, but interestingly, if displayed on the screen, it is the shape of the "pill". Only when the mode is switched in the status bar of the system, can we see the instant of the double hole digging, The rest of the time is in the shape of "pills".
It is worth mentioning that everyone is concerned about the yellowing of the hole digging screen. Some time ago, Lu Weibing also popularized science on Weibo;
The following quotes are from Lu Weibing's microblog:
First of all, the LCD liquid crystal layer is a very thin and fragile material with only 3 μ m. The liquid crystal layer is covered with two parallel layers of glass (CF color film and TFT substrate respectively). The two glasses are kept parallel in an ideal state. In theory, the liquid crystal will not turn yellow. Only when the parallel state of the two layers of glass is broken, the screen will turn yellow when the uniformity of the liquid crystal changes.
So in order to avoid the deformation of two layers of glass, the new generation of hole digging screen of Redmi K30 starts from two aspects:
1. Upgrade Thick Glass. The two layers of glass are strengthened, and the overall thickness is increased by 14% to increase the structural strength;
2. Increase the density of support column. A large number of PS support columns are added around the hole, and the density of the support columns is much higher than that of the ordinary screen, ensuring the stability of the two glass structures around the hole.
As far as the author's actual naked eye observation is concerned, there is no yellowing of the screen around the K30 hole, but if the angle is slightly tilted, some light leakage can still be seen, which may also be the pot of the LCD screen;
In fact, regarding the yellowing and light leakage of the hole digging screen, the vivo S5 released a few days ago was well controlled. The hole digging screen of AMOLED (if there is no accident, the vivo X30 should also be this screen) did not appear yellowing and light leakage. Moreover, the aperture is also very small, and the sense of existence is relatively low, which impressed the author deeply.
The K30 uses the side fingerprint unlocking scheme this time. For the side fingerprint unlocking, people who like it very much and people who hate it will hate it very much. As far as the author is concerned, I still like the K30 side fingerprint identification (note: not all side fingerprints, such as Sony, I don't like it);
The actual unlocking speed is very fast. When the phone is held normally, the fingerprint identification area is also near the thumb, so the thumb can be unlocked with just a touch (it can also be set to press to unlock). Personally, this unlocking experience is better than screen fingerprint unlocking. If you are used to holding the phone with your left hand, you can enter the fingerprint of the left index finger, But the unlocking experience is not as easy as the right hand;
In addition, I don't know whether it is because the fingerprint identification area on the side is small. If the fingerprint is not recorded at the edge when entering, the unlocking rate will decline. So try to enter more fingerprints at the edge of the finger during the entry process to have a better unlocking rate.
Next, let's talk about the hand feeling. The weight of the phone is 208g, and the thickness of the body is 8.79mm. The hand of the whole machine is relatively thick. Fortunately, the glass radian of the back is relatively large, so it fits the palm of the hand. The hand feeling is good.
There are speakers, Type-C connectors and 3.5mm headphone holes at the bottom; There is an infrared remote control sensor at the bottom.
The design of the back camera is also the place most people complain about. The design of the "coin slot" is also inexplicable. When looking at the rendered picture, it will be a bit awkward, but it is still acceptable after the real machine is used.
screen
The K30 adopts a 6.67 inch LCD screen with a resolution of 2400 * 1080 and a screen ratio of 20:9. Of course, the biggest highlight of this screen is the 120Hz refresh rate. Let's first look at the measured data;
The measured data of the K30 screen is still OK, especially in terms of color accuracy. The performance is very good, and the actual appearance is also very good, not to mention the LCD screen, which is superior to most 1080P A screens on the market today;
The best point of this screen is the 120Hz screen refresh rate (heart: high refresh rate YES; Due to the LCD screen, there will still be drag shadows, but the author thinks that daily use will not have a great impact. As for whether it is acceptable, we suggest that you go to the nearby Xiaomi Home.
performance
The K30 4G version is equipped with Snapdragon 730G SoC, which is also commonly used at this price, 6GB/8GB running memory, 64GB/128GB/256GB UFS2.1 body storage. We have the 8GB+256GB version. Let's see the measured scores.
CPU
GPU
Flash Memory
The performance of the Snapdragon 730G can only be said to be enough now. It is certainly no problem for daily use. Playing popular mobile games can barely cope with it. There is still a big gap between the performance and the flagship SoC, but after all, the price is there, and there is no bicycle.
photograph
K30 rear four camera: 6400W+800W+200W+200W; The main camera launched the Sony IMX686 sensor, which is 64 million pixels, 1/1.7 inch sensor size, aperture f/1.7, and supports the pixel 4 in 1 technology. The unit pixel size is 1.6 microns, and the parameters are close to that of Huawei flagship IMX600; The ultra wide angle model is OV88568 million pixels, aperture f/2.2; And a 2 million pixel macro lens and a 2 million pixel depth of field lens;
Let's take a look at the live photos:

The daytime performance of the main camera is quite good. The color tuning is simple and elegant, and it always looks light. The tolerance of the photos is also high, and the analytical power is no problem; Ultra wide angle performance is normal; The night scene is not as bright as that in the daytime. Although there is no optical anti shake, the noise, glare and control of the image are good; To summarize the photography part of the K30, the first IMX 686 was adjusted well, and the quality of photography exceeded the price level, but the lack of a telephoto lens was a pity.
experience
The system is based on Android 10's MIUI 11.0.5. It is still a familiar MIUI. All kinds of practical functions are available, and daily use is very smooth. In addition, the system animation of MIUI is also good, and with a 120Hz refresh rate, it is really silky smooth;
The vibration motor is a rotor motor with ordinary vibration and negligible requirements for vibration. The speaker is still Xiaomi's proud "1217 superlinear speaker", but in the final analysis, it is a single speaker. Considering the price, there is nothing to say, but I hope Xiaomi and Redmi can use dual speakers on high-end flagship in the future.
The K30 also has an infrared remote control function, which is very convenient to turn on the air conditioner and TV at ordinary times, and the full-featured NFC is not absent. You can bind access cards, bank cards and open bus cards.
Charging&endurance
K30 is equipped with 4500mAh battery. After two hours of endurance test, the remaining power 83% The endurance performance is satisfactory. The 120Hz screen refresh rate is really not a fuel saving light. According to the author's moderate use, it is about the level of charging every day.
Charging: equipped with a 27W charge pump for fast charging, the same model as Xiaomi 9. After our measurement, the peak charging power is 25W Starting from 5%, the battery can be charged from 10 minutes to 20%, 30 minutes to 54%, one hour to 93%, and it takes one hour to 13 minutes (73 minutes) to fully charge. This performance is good for a 4500 mAh cell phone.
summary
The author thinks that the Redmi K30 4G version is still a good one, in which the 120Hz screen refresh rate has increased a lot of points. The first IMX 686 has also performed well in practice, and it has extremely advanced 3.5mm headphone holes, infrared remote control, full function NFC, 27W fast charge, etc, The configuration of the Redmi K30 4G version is worthy of this price. The above is all the content of the evaluation of the Redmi K30 4G version. If you have any related questions, please leave a message.
