Redmi K20 Pro Review: All Rounder Flagship Killer

Sanjeev Dulal 2 Oct, 2019


The build of the Redmi K20 Pro feels premium from the get-go, it weighing about 191g and its thickness about 8.8mm. The gradient pattern on the rear end, as Xiaomi calls it ‘The Aura Prime Design’ gives this phone a graceful yet sleek touch, ensuring a comfortable feel altogether. And it comes in 3 exceptional color range to choose from, Flame red, Glacier Blue and the Carbon black. How cool is that!  Redmi k20 runs in Android pie with the latest MIUI version 10 OS. it comes with three variants, a base model with 6GB RAM + 64GB, 6GB RAM+128 GB internal memory and a higher-end configuration of 8GB RAM +256 GB internal memory with 6/128 variant being priced at 49,999. 

Pros Cons
  • Eye-catching design
  • Blazing fast performance
  • Impressive 48MP camera
  • Great value for money
  • Camera blows out highlights and HDR mode too aggressive
  • HDR playback only on YouTube

Design and Display

Now at a glance, the bottom end of the phone is equipped with a single speaker and USB Port C along with a SIM card slot that supports dual Nano-SIM cards whereas the top portion has a slot for the pop-up selfie camera to rest and a 3.5mm headphone jack. I really love how Xiaomi went with keeping the headphone jack which is a plus point for all the headphone lovers including myself. Two microphones are placed at either side, its sole purpose is the noise cancellation. The volume and the power button are positioned comfortably on the right side. However, there is no slot for Micro SD card so no provision expandable storage.

K20 Pro Design

I cannot help myself but talk about the 6.39-inch full HD+ notch-less AMOLED display along with an impressive 91.9 screen to body ratio that accounts for a full-screen viewing experience. The fingerprint sensor is in-built within the display for unlocking or you can also go for the pop-up camera AI unlock according to your own preference. The entire display comes with the Corning Gorilla Glass 6 protection. Redmi K20 Pro also gives you a feature of system-wide dark mode which is what most of the phones lack to provide.

K20 Pro design and build


Redmi K20 Pro excels in performance as it is armed by flagship and most powerful Qualcomm Snapdragon 855 built on 7nm process technology which exponentially improves your mobile experience. With more process speed and less battery consumption, the smooth running of the phone is guaranteed. 

Relying on benchmarks, the Redmi K20 Pro is significantly faster on some tests like AnTuTu and Geekbench but slower on some like 3DMark and GFXBench. Based on that, it seems the K20 Pro’s CPU is much more well-optimized than the OnePlus 7 Pro but the GPU works better on the latter.

Redmi K20 Pro Software

In real-world usage, you won’t find any significant difference compared to other Snapdragon 855-powered flagships. The fact that this is the most affordable phone powered by the flagship processor makes it noteworthy, but otherwise, there’s nothing new in terms of performance. Daily tasks like shooting photos, browsing the web and launching apps are all blazing fast and happen without a hitch. What was interesting to note was how well Xiaomi manages resources. On the 8GB RAM variant, apps launched hours back resumed right where I had left it.

The software on the Redmi K20 Pro is very unlike Xiaomi in one sense. There’s an app drawer! A swipe up from the home screen will bring up the app drawer and it automatically divides apps into different categories which are accessible by swiping right. There are also some other new additions. A Game Turbo mode, which houses all the installed games in a carousel, gives you some granular access to game settings. PUBG Mobile, as in most phones these days, got some special treatment. You can control the touch and repeat touch latency as well as a marked area to prevent accidental touches.

I occasionally play games on my mobile but if you’re a fan of mobile games, then I suggest you to definitely own this phone. Why am I saying this? It’s because this phone provides you with the separate gaming mode named “game turbo mode” version 2.0 which provides you with the most amazing mobile gaming experience with better gaming performance and custom game display enhancement features.


Now, on to the phone’s strongest area, it’s Camera. The triple AI Rear camera along with a 20 MP pop-up selfie camera makes this phone stand out. The photos taken by the rear camera look beautiful, thanks to its 48MP Sony IMX582 ultra-high sensor camera. The 13MP ultra wide-angle camera with 124.8-degree FOV lets you take wide-angle shots of landscapes along with The third 8MP telephoto camera that allows a seamless zoom up to 2x that helps you capture your pictures from quite a distance. The camera also comes with steady handheld night photography which adds more to the already impressive camera traits of the Redmi K20 Pro. The only downside is that the wide camera cannot take advantage of night mode.

Video capturing on this phone is also a treat as it supports the 1080p recording at either 30fps or 60fps along with an option to choose the 720p recording at 30fps. The infamous slow-motion is also available with 1080p recording at 120fps or 720p recording at either 120/240/960 fps that allows you to take perfect slow-motion captures. 


As any smartphone user would love, Redmi K20 comes with 4000mAh battery life with 27W fast charging which I think is a notable feature on its own.

All and all, Redmi K20 Pro stands out among other smartphones with its majestic camera specs, captivating design, and reliable battery life, making it one of the most attractive phones in the present day.


The Redmi K20 Pro has all the bells and whistles of an affordable flagship. We won’t outright call it a premium flagship since there are still some features that are missing that make a device premium. Yet, the K20 Pro incorporates all the features that are in vogue this year — a bezel-less display, the pop-up camera on the front and triple cameras on the back, a gradient design and flagship performance. If you were wondering, the Redmi K20 Pro is also much more than what the Poco F1 offered. The Poco flagship focused only on performance while the K20 Pro is an all-rounder of sorts. While the price does come close to what other Snapdragon 855-powered flagships ship for, it’s still the most affordable flagship you can buy right now that comes with all the bells and whistles that are in vogue this year.
