If you desire a beautiful phone then your choice should be the Xiaomi Mi 10S. Thanks to its curved edge-to-edge display and its higher screen-to-body ratio, it looks more elegant and futuristic than Redmi K40 Pro. The latter has a flat display with thicker bezels and, despite it comes with a rear side very similar to the original Mi 11, it looks less attractive due to the front panel. On the other hand, the Redmi K40 Pro offers the IP53 certification which guarantees resistance against dust and splashes. Further, it is thinner and lighter than the Xiaomi Mi 10S.


The most advanced display is the one of the Redmi K40 Pro. It is an AMOLED panel with a diagonal of 6.67 inches, the HDR10+ certification, and a Full HD+ resolution. Compared to the Xiaomi Mi 10S, it has a higher refresh rate (up to 120 Hz) and a higher peak brightness (up to 1300 nits). These are the main specifications making this display superior to the internal rival. Both the screens have an in-display fingerprint scanner, but as mentioned above, only the Xiaomi Mi 10S has a curved display, while Redmi K40 Pro is flat.

Specs & Software

With the Redmi K40 Pro, you actually get a stronger hardware department: the phone is powered by the Snapdragon 888 mobile platform instead of the lower-end Snapdragon 870 found on the Xiaomi Mi 10S. While the Snapdragon 888 is Qualcomm’s flagship SoC for 2021, the Snapdragon 870 is an upgrade of the Snapdragon 865+. The Xiaomi Mi 10S has a memory configuration with more RAM (up to 12 GB), but the processor is definitely more important. Both the phones run Android 11 customized by MIUI 12.


If you are looking for the best camera phone, the answer is Xiaomi Mi 10S. First of all, it has a better main camera: a 108 MP sensor with a bright f/1.7 focal aperture and OIS. Further, with the Mi 10S, you get a better ultrawide sensor with a 13 MP resolution. The Redmi K40 Pro has a better 5 MP macro camera, but it comes with an inferior 64 MP main sensor without OIS and an 8 MP ultrawide camera. There is no challenge: the Mi 10S is a camera phone close to the high-end segment, while its rival has a midrange-class camera.



As mentioned in the design paragraph, the Xiaomi Mi 10S is thicker and heavier. There is a reason for this: it packs a bigger 4780 mAh battery. That is the reason why it provides a longer battery life. Further, unlike the Redmi K40 Pro, it supports fast wireless charging with a power of 30W and reverse wireless charging. The Redmi K40 Pro, instead, only comes with 33W wired fast charging.


Xiaomi Mi 10S is priced at about $670/€562 in its base variant, while Redmi K40 Pro costs just $580/€487. The Xiaomi Mi 10S has an inferior display and an inferior processor than Redmi K40 Pro, but it is actually a superior phone because it packs better cameras, wireless charging (reverse wireless charging too), a bigger 4780 mAh battery, and a more beautiful design with a curved display. However, if you do not care about these features such as gamers, Redmi K40 Pro can let you save money while still keeping the same user experience. If you are a gamer, indeed, you would most likely be happier with a more powerful processor and a display with a higher refresh rate.
