Setting the bar for mid-range smartphones

March 31, 2022 0 Comments

There is a new competitor in the mid-range smartphone segment and this should not be taken lightly by a company. The Redmi K20 brings a Qualcomm Snapdragon 730 pack, the first mid-range smartphone to do so, giving it a distinct advantage over other devices on the market. Warm to cure Realme X, we have the Redmi K20, which is a bit more expensive, but is the price difference worth it? We got the answer.


The Redmi K20 features the first mover to bring the Snapdragon 730. This means that for the time being, it is at the top of our performance chart. First of all, let’s talk about CPU performance. In our AnTuTu test, we see the Snapdragon 730-powered Redmi K20 Blast surpass the Realme X’s score of 215186, which is about 28 percent higher than the Realme X’s 168272. This kind of performance difference is further confirmed by our GeekBench numbers6 For single core performance, the Redmi K20 scores 2543, up 74 percent from the Realme X’s 1455. This difference in performance can be attributed to the fact that the larger cores of the SD730 are based on ARM’s Cortex A76 and the SD71. , Of the Cortex A75. In the multi-core test, the performance difference is slightly higher, with the K20 scoring 6963 and the Realme X scoring 5968. .

As we move towards graphical performance, we see a similar push in numbers. GFXBench outperforms the K20 in all the mid-range phones we’ve tested so far this year. Proceed to the graph below and prove our point.

While the benchmark numbers certainly impressed us, real-world performance was no different. Gaming butter was smooth, PubG consistently maintained 30fps. The same goes for Asphalt 9, which is usually not one of those demanding games for the well-optimized nature. Shadowgan legends also ran fairly well on the phone, just two, minor examples of stuttering. All gaming metrics were recorded using a gamebench. In terms of gaming, the Redmi K20 is surprisingly good.

Even in everyday use, the Redmi K20 is definitely a sophisticated device. There is no place for the fridge or app to crash. It’s amazing to see how far mid-range smartphones have come, offering such reliable performance. However, this mid-range smartphone is not the only thing.

The camera

The Redmi K20 has three cameras on the back, each with a function. Includes a 48-megapixel primary camera. It is a Sony IMX 582 sensor, which, like the IMX 586, saves its frame rate when shooting 4K video. Apart from that, their performance should be the same. We have an 8 megapixel 2x telephoto lens and a 13 megapixel ultra wide camera (12mm). None of the cameras offer optical image stabilization and only offer EIS, so the final focal length may vary depending on the amount of vibration detected by the camera.

When the initial camera is tested first, we notice that the binned result (default shooting mode) is excellent with the sharpness of the impressive center. The edges tend to lose some sharpness, but are only visible when you’re shooting a large group or shooting something nearby. The 48-megapixel output of the same scene, however, shows a great lack of sharpness and contrast. Judging by the 48MP images themselves, we think the results are definitely unpleasant, but kick the camera in regular 12 MP mode and we have the winner. HDR algorithms handle backlighting fairly well. As we have seen on other phones before the Redmi K20, the 48MP sensor has great output during the day. We suggest you view all of our original photos Here is the Flickr Gallery.

The ultra wide-angle lens offers a 12mm field of view, the widest of the smartphone cameras at the moment. The output has decent center of sharpness, but in the review sample of the phone we received, the images showed extreme degradation in the sharpness of the corners. Again, the camera is usable during the day and for social media posts, but low light performance is certainly not its powerful suite.

Ultra-wide camera handles harsh light well, but shots lack detail and sharpness

The telephoto lens offers a 53mm field of view with an aperture of f / 2.4. There is no OIS, only EIS and we have noticed that in many situations, especially when shooting indoors or in low light, stability is not as effective. Other than that, when it works, it gives pleasing results.

Telephoto cameras could have been more impressive with OIS

Overall, the images from the Redmi K20 are impressive, but there are two areas where the camera stack is damaged. The first is autofocus and the second is shutter response. We noticed that for almost all photos where we chose the focus point manually, the focus was slow, sometimes unable to lock on the subject. The shutter response also took a fraction of a second longer than we would like, which can cause motion blur when shooting a moving object.

Night-mode photos are not so impressive

Selfie camera

The 20-megapixel pop-up camera is quite a bit. While its imaging capabilities are decently impressive as far as selfies go, we like that Xiaomi has done some clever work on the module. When the camera goes up, everything is illuminated for the embedded LED It’s a nice touch that ensures that everyone in the selfie knows where to look

When it comes to self-portraits, these are nothing short of amazing at home. They display impressive colors and contrasts, have a decent amount of sharpness, but lack a certain level of detail retention. For some reason, Xiaomi refuses to change this feature, regardless of the sensors and optics they use in their cameras. Yes, we are sure to stop the effects of beauty.


The third impressive feature of this phone is the display. The Xiaomi Redmi K20 has an HDR certified display, making this phone a natural choice for those who enjoy streaming content from Netflix and YouTube. Yes, Redmi K20 is certified by Netflix and YouTube for playing HDR content.

Thanks to the use of an AMOLED panel instead of the IPS-LCD, we get not only better color, but also brightness levels. The Redmi K20 topped our test at a whopping 589 lux, with a minimum brightness of 4 lux. While this isn’t the brightest display by any means, it’s still quite something to watch.

Outdoor use is also good enough, the panel is only subject to reflection in special situations. Honestly, if you use Redmi K20 it will be very difficult to read the contents of your display, so we will not worry about it. Just before moving around the house and using the phone was good (bad habit, we know), 4Lux had no problem with minimum brightness. Between this and the built-in dark mode, the phone is easy on the eyes, even in pitch darkness.

Battery life

How far does 4000mAh get you? Well, according to Geekbench’s battery test, use up to 12 hours continuously. According to our video loop test, you can get about 652 minutes of video playback, although this number will vary depending on what you play. We noticed only a 6 percent battery drop in battery percentage when navigating for an hour and a 4 percent battery drop in PubG’s 15 minute round. The phone takes 110 minutes to charge from zero to 100 and this is because the K20 18W supports fast charging, not fast. In our daily use, the phone easily lasts one and a half days of medium to heavy use. Although it is worth noting that we used the phone set to dark mode with the interface. Suffice it to say, we have no complaints here, although we would have preferred fast charging.

Design and build

No matter how you look at it, it looks nothing like a phone competing with the Redmi K20. In fact, the phone looks nothing like what Xiaomi has done in the past. It has a design inspired by fire and ice and not a single person on our team disliked the color treatment. The front and back are protected by Gorilla Glass 5, making the phone a little slippery. The rear edges are gently bent into the metal frame where they are fastened quite well. But that means keep the phone on a slanted surface and it is likely to slip.

What we noticed when we took the phone out of the box was how heavy it was, and it was well made. Honestly, you hold this phone and it looks like something much more expensive, like a OnePlus 7 Pro. This phone inspires you to use it without case, due to its remarkably beautiful appearance and its sturdy structure. However, it’s still glass and we can’t help but recommend using a TPU case so you don’t ruin it with one drop.

The last row

Finally, whether to buy the Redmi K20. The short answer is, if you have money, go for it. No questions asked. There is nothing that is offered by competing devices that K20 does not offer, save for a microSD card slot. We’ve reviewed the more expensive 6GB RAM and 128GB storage variants, but we hope that the 6GB RAM, 64GB storage variant will also perform. While we believe that the imaging experience can be improved through software updates, we will not hold our breath to get closer to Xiaomi.
