Redmi K20 Review

     Xiaomi has finally brought the Redmi K20 to India after its launch in China this May. The Redmi K20 price in India starts at Rs 21,999, and for that price, the phone offers a stunning design, a low-AMOLED display, triple rear cameras including a 48-megapixel main snapper, a large 4,000 battery and 18W fast charging Does. . And did we mention that MIUI will show fewer advertisements on Redmi K20? Yes, Xiaomi has finally heard tsunamis and claims of complaints as part of its advertising strategy. The Redmi K20 is loaded with powerful hardware that is difficult to find elsewhere in this price bracket and boasts a sneaky design that will definitely turn heads.

This new Xiaomi phone seems to outperform its competition in terms of specifications, but does it perform well enough? To know in depth about us, read the Redmi K20 Rs. 21,990 review.

Design and Look

The design of the Redmi K20 is one of its biggest attractions. The flame-inspired gradient pattern on the rear panel of our Glacier Blue Review unit looks eye-catching, while the middle black stripe contrasts with the dynamic pattern on both sides.

Xiaomi calls this aura prime design and says that it has been achieved using a 6-layer stacking process. The back of the phone is made of curved gorilla glass. This design has been seen in the Glacier Blue and Flame Red variants of the phone, but Xiaomi also offers the Redmi K20 in the Carbon Black variant, which is slicker and more understandable like Kevlar.

As for ergonomics, the curved glass panel ensures a comfortable grip, but the Redmi K20 is quite slippery and the rear panel also smoothes out quickly. Thankfully the retail package includes a tough protective case that has a matte finish and provides a more assured grip.

The frame series running around the edges of the phone is made of 6000 aluminum and matches the color scheme of the rear panel. Overall, the Redmi K20 is solidly built and feels premium to the Get Go.

The phone has Gorilla Glass 5 on the front and back. The volume and power buttons are comfortably positioned to the right, and both provide good tactile feedback when pressed. The power button has a red accent and stands out from the rest of the body. The camera module on the back of the Redmi K20 is slightly stretched, but it is not enough to waver the phone while lying flat.

The pop-up front camera module has LED lights that glow when lifted in dark surroundings. It also has a small ring at the top which lights up and acts as the notification light of the phone, but most of the time it is difficult to notice when the phone is flat.

Xiaomi has trimmed bezels on all sides of the screen to give the Redmi K20 an all-screen look. The chin is thinner than other phones in this price segment, making the phone look modern.

Display and Performance

The 6.39-inch AMOLED display of the Redmi K20 is superb, and is especially evident when MIUI's Dark Mode is enabled. The colors just pop, and the viewing angles are also good. The display offers a peak brightness of 600 nits, but we did not feel the need to crank the brightness to 80 percent mark even in daylight.

Sunlight's legability was also good and the contrast level for a phone in this price segment was excellent. Reading emails and viewing content on the Redmi K20 display was easy on the eyes. However, we found that screen brightness was sometimes adjusted incorrectly, requiring us to manually reset it using the slider in the notification shade.

The display is HDR certified, but it is unclear what standard Xiaomi has used. The Redmi K20 is currently absent from the list of Netflix phones that support HDR10 content, meaning that you cannot currently watch HDR 10 content on phones from Netflix - yet, at least. However, we were able to watch HDR videos on YouTube. The full-screen display looks great and is also good for viewing content without a camera hole or without a notch.

The AMOLED panel is slightly warmer by default, but one color can adjust the temperature and be the opposite of their choice. Users can set the brightness and temperature of the night mode independently, and there is also a reading mode. In short, the Redmi K20's display is the best in its price bracket.

According to the phone's performance, the Snapdragon 730 SoC with its eight Kryo 470 cores and Adreno 618 GPU really blurs the lines between the flagship and mid-range models. We did not come across any lag or instances of cold while using the phone. Even with 10-15 apps running in the background, switching between them was smooth.

The Redmi K20 also had no problem with high-end games. We played PUBG Mobile in high graphics settings and did not see any noticeable frame drop or stutter. Xiaomi has implemented some neat features and claims to increase speed with its Game Turbo 2.0 tool. In PUBG Mobile, for example, players can adjust the touch response and sensitivity of the screen to tap repeatedly. You can also reduce the touch sensitivity around the edges of the screen to avoid accidentally turning on the navigation gesture.

There is also a feature called 'Enhanced Visuals' located in the 'Additional Settings' of the Game Booster app, which allows users to choose between visual presets labeled Original, Medium, Strong and Extreme. However, they only appear to twist the contrast and shadow based on the selection.

The Game Booster also provides a quick settings panel that can be accessed by swiping from the top-left corner of the screen. It shows statistics such as CPU and GPU usage, and also provides nifty shortcuts for tasks such as screenshot grabbing, recording gameplay, and clearing memory.

There are also shortcuts for apps such as WhatsApp and Facebook, which can be opened in small floating windows. This implementation is similar to Game Genie on Asus ROG phones (review).

At PUBG Mobile, we recorded an average of 30fps on high graphics presets, which is not too shabby. As far as the synthetic benchmark is concerned, the Redmi K20 reached a score of 214,685 in AnTuTu. In Geekbench's single-core and multi-core tests, the phone scored 2,537 and 6,910 respectively. The GFXBench T-Rex returned 58fps, while the GFXBench Manhattan 3.1 score was 23fps.

The Snapdragon 730 of the Redmi K20 is not at the level of the Snapdragon 845, which empowers many of the previous year's flagship which still cost around Rs 25,000. But this is a solid upgrade over the Snapdragon 710 and Snapdragon 675, both of which are now very common at this price level.

Specifications and software

The specifications of the Redmi K20 are quite impressive for phones starting at Rs 21,999. The hardware of this phone is almost as expensive as the Redmi K20 Pro at Rs 27,000, with two major differences. The Redmi K20 Pro is powered by Snapdragon 855 and employs a 48-megapixel Sony IMX586 sensor for its primary rear camera, while the Redmi K20 gets the Snapdragon 730 SoC and is equipped with a slightly lower-end 48-megapixel Sony IMX582 sensor.

The only difference between the two sensors is that the Sony IMX586 can record 4K video at 60fps, while the Sony IMX582 can only record up to 30fps. Xiaomi apparently went with the latter because the Snapdragon 730 does not support 4K video encoding at 60fps anyway.

The Redmi K20 features a 6.39-inch full-HD + (1080 x 2340 pixels) HDR AMOLED display with a 19.5: 9 aspect ratio, an impressive screen-to-body ratio of 91.9 percent, 403ppi pixel density and 600 knots of bright brightness. is. . The display is protected by Corning Gorilla Glass 5.

The in-display fingerprint sensor in the phone is quite quick and accurate, and unlocked the Redmi K20 within a second during our usage. While setting the fingerprint sensor, we were warned that using an adhesive screen protector could interfere with the scanner, and only an authorized protective cover compatible with the phone should be used.

The Redmi K20 comes in two variants - a base model with 6GB of RAM and 64GB of internal storage that we have for review, and a high-end configuration with 6GB of RAM and 128GB of storage. Unfortunately, there is no MicroSD card slot for storage expansion.

There are three rear cameras - a 48-megapixel Sony IMX582 sensor with f / 1.75 aperture, an 8-megapixel secondary camera with a telephoto lens and a 13-megapixel camera with f / 2.4 aperture and ultra wide-angle lens and 124.8 degree field of view. The selfie is handled by a pop-up 20-megapixel camera with f / 2.2 aperture. The lens is protected by sapphire glass, while the module automatically retracts when the phone falls.

Talking about camera features, the Redmi K20 supports slow-mo video capture up to 960fps and 4K video capture at 30fps. There's a dedicated night mode, 48-megapixel mode, lighting effects, and a ton of beautification filters for play. The light is paired with a 4,000mAh battery, and this phone supports Quick Charge 3.0, so it can be topped with a given 18W fast charger.

On the software side, the Redmi K20 runs MIUI 10.3.3 based on Android 9 Pie. Our review unit ran on Android security patch on May 2019, but we expect Xiaomi to roll out an update with the latest security patch soon. The first thing we found about the Redmi K20 UI was the presence of an app drawer, which had been missing from MIUI for some time. This is thanks to the use of Poco Launcher. The other major attraction is a system-wide dark mode. The rest of the interface is typical MIUI, with lots of customization options and useful features.

The Redmi K20, unknowingly, comes with a number of pre-third-party and in-house bloatware, including Amazon, Facebook, WPS Office, Dailyhunt and Paytm, to name a few. All third-party applications can be uninstalled, but Xiaomi cannot have its own.

Some native apps like Mi Video and Music harassed us with notifications, prompting us to cancel the notification. The Mi Video app, in particular, was the main culprit and even featured a lot of content in the 'fashion' and we beauty 'categories that we would describe as ineffective and not safe for work.

A major reason for the relief was the low frequency of advertisements. Xiaomi stated at the launch event that Redmi K20 and Redmi K20 Pro will be shown fewer advertisements than people to see Xiaomi phones. We got it quite right. For example, ads that appear after installing applications from the Google Play Store are completely gone.

A few small quirks are scattered throughout the interface. Swipe gestures to switch to the last-used app do not always work. Also, for apps that have a slide-out menu on the left side, gestures cannot be done from the left edge only because the app's interface is preferred over navigation gestures.

The classification of apps in the app drawer is also not accurate. For example, downloads, file managers and Gmail fall into the Knowledge and Education category. When navigation gestures are enabled, one-handed mode cannot be activated until the Quick Ball tool is activated.

One minor inconvenience, which may well be a pet, is that the keyboard is pushed downwards, without Android navigation buttons on the screen when gestures are enabled. We found it less comfortable and our typing was also less accurate. Another issue was face recognition. It performed admirably in well-lit conditions but struggled in low light.

Nevertheless, overall, the MIUI on the Redmi K20 feels slightly more sophisticated than its implementation on other Redmi series phones. The ambient display feature is a neat touch, and we have at the very least liked dynamic wallpaper in which the sun changes its position on a circular path depending on the time of day.

Camera and Battery Life

The Redmi K20 offers the same camera hardware as the flagship Redmi K20 Pro (except for the sensor differences discussed above), and makes a solid statement for a phone that costs about two-thirds of the budget, like the OnePlus 7 (Review ) Or Asus 6Z (Review). The third rear camera is an added bonus. In our camera tests, the Redmi K20 punched well above its class.

The camera takes 12-megapixel pixel-binned photos by default, but has a 48-megapixel mode if you need full-resolution 48-megapixel photos. The images captured by the main sensor are crisp and contain much detail. Dynamic range is also good. We notice that the Redmi K20 captures images at high ISO levels by default in daylight, and some of our shots are slightly oversized.

In close-up, the gradients are reproduced in vivid detail with good contrast, but the edges of the objects appear slightly softer, and the highlights around the bright objects are overblown. Shooting in 48-megapixel mode brought more detail and deeper contrast, but we prefer 12-megapixel photos because they look more vibrant.

The macro shots captured by the Redmi K20 retain an impressive amount of surface detail and feature punchy colors. The camera sometimes greatly overpowers the colors, robbing shots of real-life colors. Disabling AI camera mode helped with this color inaccuracy problem to some extent.

The telephoto camera is used for portrait shots and does a good job of separating subjects from the background. Edge detection is also on point. The blur effect is applied equally, and there are also a host of portrait lighting effects to play with. Portrait shots captured in daylight look great, but those that are captured indoors or in low light show a grainy texture when zoomed.

The wide-angle camera takes pleasing pictures, and thanks to the distortion correction feature, we didn't notice any unnatural warfare in the shots. One area in which the Redmi K20 leaves much to be desired is low-light photography. The low-light shots we took featured too much noise and poor color.

Dedicated Night Mode helps with noise reduction and increases brightness, but details and colors are missing. Night mode simply increases ISO and does little to speed up objects in the frame. Nevertheless, compared to the regular mode, the Night mode does a good job with the theme display.

Low-light images captured by wide-angle cameras are also low, with poor exposure, lack of detail, and grainy texture. We found that the Motorola One Vision (Review) Night Mode was better than its implementation on the Redmi K20. It is also worth noting that wide-angle cameras cannot take advantage of night mode.

The 20-megapixel pop-up selfie camera makes up for some of the drawbacks of rear cameras. The selfie captured by the 20-megapixel front camera demonstrated minimal over-processing, and this phone could capture natural colors with an impressive amount.

The portrait selfie had good subject separation and edge detection, but they are slightly less sharp than regular selfies. Our only gripe with the front camera is low dynamic range and lack of sharpness when clicked indoors or in dimly lit environments.

4K videos capture a good amount of detail and feature natural colors. OIS is not, but EIS does a commendable job of neglecting hand movements. Dynamic range is also better than 4K videos captured by phones that fall under the same price bracket. 4K videos shot by ultra-wide-angle cameras are slightly oversaturated and have a lower dynamic range than what the primary camera can hold. Slow-mo videos went on smoothly, and with steady hands, we could capture some social-media-worthy clips at 960fps.

Battery life is another strong area of ​​the Redmi K20. Our use of over a week, which included using social media and productivity apps, included an hour of gaming, a few hours of listening to music on Bluetooth headphones, and intermittent calls, with the phone still in about 30 to 35 percent The battery was left in the tank at the end of each day.

In our HD video battery loop test, the phone lasted an impressive 25 hours and 17 minutes. The supplied 18W charger took the 4,000mAh battery from zero to 45 percent in 32 minutes, and required about 1 hour, 40 minutes for a full charge.

Verdict : should you buy it?

There is some outrage over the Redmi K20, with many fans and potential buyers expressing disappointment that the company has not targeted the sub-Rs 20,000 segment. The bottom line here, though - the Redmi K20 is the heaviest and feature-rich non-flagship 'phone under Rs 25,000 in the market right now, and given its price, its performance is still great today.

The design of the Redmi K20 is attention-grabbing and this phone will stand out in a sea of ​​glass slabs and Gerris grades. The display is of excellent quality, and the in-display fingerprint sensor is also quick and reliable.

The camera hardware is impressive, and save for a bit of under-performance and some other minor issues, the overall quality and versatility you get is a notch above the competition. The battery life of the phone is also amazing, and you can easily sail through a day and more with each charge.

The Snapdragon 730 SoC provides power to this phone as well as a kind of free experience in the most demanding situations. A refined MIUI with fewer ads, features such as a dark mode, app drawer and ambient display, further sweeten the deal.

If you're looking for options, last year's Snapdragon 845-powered flagship such as the Poco F1 is worth Rs 23,990 (review) and the Asus Zenfone 5Z (review). The Samsung Galaxy A50 Rs 15,499 (review), Vivo V15 Pro Rs 19,700 (review) and Nokia 8.1 (review) are the other mid-range options, but none of them match the overall price and performance offered by the Redmi K20 does not make.

If you want to save some money and do not want to go above Rs 20,000, then Realme X (Review) is an excellent option right now. Other options include Samsung Galaxy M40 Rs 14,990 (review), Realme 3 Pro (review), Vivo Z1 Pro Rs 15,199 (review), and Redmi Note 7 Pro Rs 12,990 (review), however, again, none of them Will not offer As appealing an overall package as the Redmi K20.
