If we rely simply on the aesthetics of the Xiaomi Mi 9 and the Redmi K20 Pro, we could say that they are two totally different phones. For its part, the flagship of Xiaomi keeps a notch in the form of a drop of water on its 6.39-inch screen, while the Redmi K20 Pro has a front “all-screen” getting a greater sense of immersion thanks to its camera. It is located in a new pop-up type retractable system.

In short, we must consider that the thickness and weight of the Redmi K20 Pro are slightly higher than that of the Xiaomi Mi 9. But, in turn, Redmi’s flagship offers a better feeling when playing multimedia content on your screen without any kind of notch.


For its part, if we focus on the performance of these two devices, we could say that in both it will be very similar. Specifically, both the Xiaomi Mi 9 and the Redmi K20 Pro have the same processor, namely the powerful Snapdragon 855. A state-of-the-art processor that incorporates an Adreno 640 graphic inside.

Redmi K20 Pro Performance


We can find a small difference is in storage capacity and RAM. And it is necessary to bear in mind that the GLOBAL version of the Xiaomi Mi 9 only has 6GB of RAM and 64 / 128GB of internal storage, while the Redmi K20 Pro, until its GLOBAL version, allows you to buy it from China ( GLOBAL ROM version) with up to 8GB of RAM and 256GB of storage.


The second point where we find small changes between these two high-end devices is in their cameras. For its part, both phones have a combination of the triple rear camera on a single sensor for your selfie camera. Even so, although the main sensor of both is the same SONY IMX586 48MP, with an aperture of f / 1.75 and pixel size 0.8μm. Both the wide-angle sensor and the telephoto lens that at the same time performs the tasks necessary to read the Image depth and thus get the famous bokeh effect are slightly lower in the Redmi K20 Pro.

A small change that we can find in the opening size of these two sensors, while those of the Redmi K20 Pro is f /2.4, the Xiaomi Mi 9 can capture a greater amount of light thanks to its opening f /2.2. Still, as we said, the changes are quite small and unless we use the portrait, telephoto or wide-angle effect quite frequently, we will not notice much difference between the two.

Redmi K20 Pro Camera

The same happens with the front camera, in the case of the Xiaomi Mi 9 its 20-megapixel sensor manages to capture a greater amount of light and also store more information per pixel.

It should be noted that although certain comparative videos of these two are circulating through the network, showing also quite disparate results, we must bear in mind that the Redmi K20 Pro has just hit the market, so it still needs to mature in its code and that Xiaomi manages to optimize Redmi’s flagship camera software in these first months .


One of the determining points to decide which flagship to buy is found in its battery capacities. For its part, the Xiaomi Mi 9 has 3,300mAh a decent enough capacity that thanks to the great management and low consumption of the Snapdragon 855 make it last at least a whole day.

In contrast, the Redmi K20 Pro has a large battery of nothing more and nothing less than 4,000mAh. A great capacity that if in the case of the Xiaomi Mi 9 this lasts practically all day, in the case of the flagship of Redmi will ensure that its autonomy exceeds the day or day and a half or even, lasts a full day demanding a great performance from him. Therefore, if you are one of those people who can not risk running out of battery or that makes great use of certain high-performance applications such as video games, the Redmi K20 Pro is the ideal device for you.

Wireless charging

Another differentiating aspect is found in wireless charging. And it is that only the Xiaomi Mi 9 is the one that has this functionality, which in this case reaches 20W by charging the entire battery in just 90 minutes and wirelessly.

Mi 9 Wireless Charger

In the rest of the features and functionalities, both devices have small details that make them different. For its part, the Xiaomi Mi 9 has exclusive, in addition to wireless charging, an infrared port with which to control much of the devices in our home, whether it is air conditioning or our television.

For its part, the Redmi K20 Pro has an exclusive 3.5mm audio jack that is also certified with high-quality Hi-Res technology. Likewise, the speaker of this flagship has Smart PA 10V Boost, getting a volume that many consider as the largest of all Android devices on the market.

Redmi K20 Pro Media

If you are one of those who visualize great multimedia content on a smartphone, you need an audio jack and in addition, a large battery that exceeds even the day, your mobile device is without a doubt the Redmi K20 Pro.

Final words

On the other hand, if you are looking for high-quality photography device, either in conventional shots or using the telephoto, wide-angle or selfie camera and also, you want to try the wireless charging technology, the Xiaomi Mi 9 could be the phone for you.
