If you are looking for an affordable smartphone, Xiaomi, and especially its sub-brand Redmi which recently became independent from the Chinese giant, is one of the best options for you. For the first time ever, Xiaomi’s sub-brand announced a flagship-class line-up composed of a high-end model and a real flagship: Redmi K20 and K20 Pro. The latter is one of the most affordable real flagships out there and it may become one of the best-sellers of this year. But it has a lot of competition in the top-end segment: is it worth choosing it or other flagships such as Asus Zenfone 6 and OnePlus 7 Pro are better options? this comparison will give you an idea.

Design
Do not ask us for an opinion about the aesthetics of these devices: just choose what is better for your tastes. In each case, you will get a premium and beautiful design, even though I like Redmi K20 Pro and OnePlus 7 Pro more than the Asus Zenfone 6, despite the latter comes with a very useful rotating camera. Note that despite Asus Zenfone 6 comes with the same display size, Redmi K20 Pro has smaller dimensions, so it fits better in your pocket or your hand. OnePlus 7 Pro is even bigger than Asus Zenfone 6 due to its bigger display.
Display
As mentioned above, OnePlus 7 Pro comes with a bigger display which is more comfortable for multimedia and productivity; but this is not its only advantage. Its display is even one of the best panels out there, with a higher Quad HD+ resolution, a 90 Hz refresh ratio and the HDR10+ certification. It shows more realistic colors, it provides a smoother gaming and user experience, and even a higher level of detail. Even Redmi K20 Pro and Asus Zenfone 6 are equipped with wonderful panels, but OnePlus 7 Pro is the superior one and its display can be compared to the best Samsung’s ones.
Hardware/Software
Among the key feature of all of these devices, there are blazing speeds and performances. They are all powered by the amazing Snapdragon 855 chipset by Qualcomm, and you could not expect a better chipset in 2019. Despite coming with the same processor, OnePlus 7 Pro wins the hardware comparison because, in its most expensive configuration, it comes with up to 12 GB of RAM. With Asus Zenfone 6 and Redmi K20 Pro, you can get max 8 GB of RAM. On the other hand, Asus Zenfone 6 features a micro SD slot which accepts micro SD cards up to 1 TB, while OnePlus 7 Pro and Redmi K20 Pro do not have expandable storage. In each case, you get Android 9 Pie out of the box.
Camera
OnePlus 7 Pro wins the camera comparison for having the most complete and versatile camera department. It comes with a triple camera including an ultrawide lens and a telephoto lens with 3x zoom. It even has OIS, unlike its rivals, as well as the brightest focal aperture. But Asus Zenfone 6 is still an amazing camera phone thanks to its rotating camera: it shoots the best selfies and the rotating rear camera makes clicking photos much more comfortable as you can move the camera upwards or downwards without moving the phone. Even Redmi K20 Pro comes with an awesome camera and it is the only one able to record super slow motion videos at 960 fps.
Battery
There is no challenge: Asus Zenfone 6 wins the battery comparison as it comes with a way bigger 5000 mAh unit. And it even supports reverse charging (it can be used as a power bank).
Price
Redmi K20 Pro starts from just €350/$390 in the Chinese market, Asus Zenfone 6 costs €500/$557, and OnePlus 7 Pro starts from €700/$780. OnePlus 7 Pro wins the comparison thanks to its better display, amazing cameras, higher-end memory configuration. I like the Asus Zenfone 6 more than the Redmi K20 Pro, but Redmi K20 Pro wins the value for money comparison for its incredibly affordable price tag.
