Comparison: Redmi Note 9S vs Xiaomi Mi 10
Comparison: Redmi Note 9S vs Xiaomi Mi 10

It's time to change your mobile and the question comes to us: is it worth paying more than €500 for a mobile? So we wanted to face the Redmi Note 9S and the Xiaomi Mi 10, to see whether or not it is worth paying more or less for a mobile.

Xiaomi, despite having presented a €1,000 mobile, continues to struggle to gain a foothold among cheap mobile phones with great features, and among all of them, we want to highlight the Redmi Note 9S and the Xiaomi Mi 10.

Although there is a difference between the two approximately 450 euros, we did not want to miss the opportunity to face them in a comparison and see if it is necessary pay that difference or not.

We are going to start by breaking down each essential part of a mobile, so that in the end you are the ones who draw the conclusions:

Same screen diagonal, but not same quality

Having a lot of screen doesn't mean it's better, what really matters is the panel technology and its resolution.

In this comparison there are no major differences in terms of the screens of both devices, but there are subtle improvements:

  1. Xiaomi Mi 10: 6.67-inch AMOLED FHD+ (2,340 x 1,080), HDR10+, 19 aspect ratio, 5:9, refresh rate of 90 Hz and up to 180 Hz in touch, maximum brightness of 1,120 nits, ratio of 87.8% and Corning Gorilla Glass 5 protection.
  2. Redmi Note 9S: 6.67-inch IPS LCD FHD+ (2400 x 1080) 20:9 aspect ratio, refresh rate 60 Hz, 450 nits maximum brightness, 90.1% ratio and Corning Gorilla Glass 5 protection.

As we can see, both terminals have the same screen size, but not the same technology, nor the same quality. But these details are not the only ones that cause the price difference.

Processor, big differences in both terminals

In both the Xiaomi Mi 10 and the Redmi Note 9S, we have good processors capable of pleasing any fan of mobile games.

In the case of the Xiaomi Mi 10, we have a Snapdragon 865, a 2019 processor in a mobile that was officially released in mid-March 2020. On the opposite side of the ring we have a Snapdragon 720G for Redmi Note 9S, newer processor (January 2020).

The processors are not just a number and serve as the engine for the mobile, but are the key to see which mobiles can integrate it and which cannot. In other words, the processor is the main voice and the one that says what features it supports.

For example, in the case of the Snapdragon 720G, it supports displays FullHD+ up to 120Hz and with HDR+, 4G, Bluetooth 5.1, NFC, GPS, Quick Charge 4.0 with up to 30W, dual cameras and 192 MP gross sensors, but only 48 MP photos.

In the case of the Snapdragon 865 processor that mounts the Redmi Note 9S, it allows 4K HDR recording, up to 8K or photos up to 200 MP maximum, as well as 960 fps super slow motion recording, support for HDR+, 4G, Bluetooth 5.1, GPS, NFC, and displays with 4k resolution at 60Hz or QHD+ at 144Hz.

Another important piece of information is the ROM and ROM memory included in each terminal. The Redmi Note 9S has 4 or 6 GB RAM and 64 or 128 GB of ROM expandable via MicroSD up to 512 GB. The Xiaomi Mi 10 has 8 or 12 GB RAM and 128 or 256 GB ROM without the possibility of expanding.

Four cameras for both devices

We have already said on more than one occasion that more cameras does not mean better photos, nor does more megapixels mean better Photos. A clear example of this is the iPhone which, until relatively recently, only had two cameras on its back and, even so, competed at the high end.

  1. Xiaomi Mi 10: Rectangular module centered on the back and with 4 cameras. 108 MP main with focal 1.6 + 2 MP bokeh with focal 2.4 + 13 MP wide angle with focal 2.4 + 2 MP macro with focal 2.4. For selfie we have a hole in the screen with a 20 MP sensor.

Redmi Note 9S: 4-camera module in a straight line in the left area of ​​the back of the terminal. 48 MP with 1.79 focal length + 8 MP ultra-wide angle of 119º with 2.2 focal length + 5 MP macro with 2.4 focal length + 2 MP depth with 2.4 focal length. For the selfie camera we have a hole in the screen with a 16 MP sensor.

Battery and fast charging for both of you

Here, both terminals are well served, but as we always say, it depends on the good work they have done with the software and the features that we have active, so that the battery drain is normal.

The Xiaomi Mi 10 has 4,780 mAh, fast wired and wireless charging at 30W and reverse at 10W. The Redmi Note 9S has 5,020 mAh and fast charging with a 18W cable.

These charging speeds allow us to have the phone ready in a matter of half an hour or a little more, as long as we are not using it while charging. We don't say the latter for fun, but because sometimes we tend to have bad habits when charging our mobile.

A different design in almost every aspect

Since it is a comparison and two highly desired mobiles, we must compare the design and, therefore, the notable differences that can be seen with the naked eye. Some differences that may or may not mean buying the terminal:

Connectors and Connectivity

In these times it is rare to see that mobile phones still have the headphone jack, for example. In the case of this comparison, both terminals have USB C, headphone jack and SIM card slot.

The only differences that can be seen are in the MicroSD card slot which, in the case of the Redmi Note 9S, the ROM memory is expandable.

Regarding connectivity, the only one that stands out a bit is the Xiaomi Mi 10 that has 5G, its adversary follows the line normal and is maintained with 4G.

The issue of 5G is an interesting debate and one that we have already talked about at length about all the hoaxes and half-truths that exist around this new technology, since one of the most consulted doubts in Google is if 5G is harmful to he alth.

Fingerprint reader

It is a very important aspect and here there are differences, since in the Xiaomi Mi 10 the fingerprint is under the screen and in the Redmi Note 9S it is on the lateral, as we already discussed in a previous comparison with the Redmi Note 8.


Not all of us like large mobiles, but tell Apple and its new iPhone SE 2020 that doesn't even reach a 5-inch screen.

  1. Redmi Note 9S: 166.9mm x 76mm x 8.8mm and 209g.
  2. Xiaomi Mi 10: 162.6mm x 74.8mm x 8.96mm and 208g.

We reached the end wanting to know the conclusions you have drawn and, if you had the money, what would be the chosen motive? You can respond on our social networks or in the comments of this article.
