Redmi Note 10s : test / review

[REVIEW] Redmi Note 10s : test / review
Category: Smartphones

The Redmi S range first appeared in 2020 with the Redmi Note 9s. The Redmi Note 10s is a phone that fits between the Redmi Note 10 and the Redmi Note 10 Pro. The Redmi Note 10s should be seen as a phone that will take over the external appearance (size / weight) of the Redmi Note 10 with a little more performance and a better camera. It is therefore a mid-range phone that offers a good price / performance ratio and sometimes it is details that will distinguish it from the other two models. [b][b] Xiaomi launches so many models that sometimes it's hard to choose, so I'll try to highlight things that might tip you in favor of this phone. There is never really a big winner at Xiaomi, their phones are always good at something and not so good at other things, so the choice will have to be based on what is important to you. If for example the photo is a priority with you, I would say that the Redmi Note 10s should be the best choice but I could only confirm that after finishing this test.[b][b][b]linkManufacturer web site:[b]linkSite where I have bought the Xiaomi Redmi Note 10s:[b]

Structure of my tests

I test the phones according to a pre-established structure (see below) to provide you with as much information as possible. Unfortunately, this takes a long time. Some tests like network performance tests take several days and for photo tests I sometimes have to wait until the weather is suitable to take pictures in good conditions. I am therefore obliged to publish the tests step by step, so I invite you to come back if the test is not complete at the time of your visit.[b]
How are my tests different from others on the web?

- I usually buy the devices with my own money, so price is just as important as you are!
- I keep the devices for at least a few weeks (sometimes more) to see what they are worth in real conditions.
- I answer (when possible) your questions to help you decide before you buy
- no one pays me to do these reviews, so I'm completely neutral and independent...
- My pages are not filled with ads

May 12, 2020: I buy the Redmi Note 10s on Aliexpress for pre-order, I imagine that I will have to wait 3 weeks before receiving it. [b] June 23, 2020: I finally received the Redmi Note 10s after more than a month of waiting, it seems that someone came on foot from China to deliver it to me.[b]

Why this phone?

I'm always looking for good deals, I have scripts that run 24 hours a day to find the right prices. I had seen that Xiaomi was going to launch a Redmi Note 10s but I hadn't paid too much attention because I had already bought a lot of Xiaomi this year. I am all alone to do my tests, I have to make choices. I changed my mind when I received an alert for the Redmi Note 10s and its launch offer close to 150 €. At this price, it is a price close to the Poco range and the Redmi Note 10s is far from being ridiculous compared to the Poco range and it is equipped with a good photo sensor with the Samsung GW3 that I tested on the Xiaomi Mi 11 Lite. [b][b] So before overdosing on Xiaomi, I still let myself be tempted by this Redmi Note 10s, I think that this phone will find its place in the Xiaomi range and that it will come to do shade to the PRO version which is barely a little more powerful and which does not offer a better photo sensor.[b]


Xiaomi has standardized almost all of its boxes so it is not on the basis of the box that the Redmi Note 10s will stand out, in addition to its packaging it has a family resemblance with the Redmi Note 10 , we could almost confuse them. The box contains the phone, a transparent soft silicone case, a manual, a charger and a type-c usb cable. [b]

First configuration

The Redmi Note 10s is the first phone I tested with MIUI 12.5 installed by default, I have never tested this version of MIUI on other phones before. Does this change anything? Yes and no. The graphical interface of the phone configuration is different, the screens have been revised with more space for illustrations and the interface is generally more airy. The configuration steps do not change and the fact of having redesigned the MIUI screens, the difference between these screens produced by Xiaomi and those imposed by Google becomes even more obvious. [b][b] The improvement is therefore mainly of a cosmetic order and the remarks I made previously remain entirely valid with in particular this desire of Xiaomi to try to impose its cloud and its applications is a constant at Xiaomi. [b]


The Redmi Note 10s is an entry level phone but at Xiaomi using the term "entry level" is not derogatory because year after year Xiaomi has managed to produce more and more phones interesting in this price range and today Xiaomi is undoubtedly the brand that offers the best quality / price compromise. The Redmi Note 10s has a lot of similarities with the Redmi Note 10 (therefore without an S). It has more or less the same dimensions, the photo block is very similar and the material used on the back of the phone is almost identical. [b][b] The back of the phone is made of plastic and offers a slightly metallic reflection of light. This is a recipe that Xiaomi has already used on other phones by varying the colors and the type of photo block. This format is nothing original but I find that the whole is quite successful, it does not breathe premium but the phone does not deform on the back as was the case with the Redmi Note 9. [b][b]
The photo unit sticks out a bit at the back of the phone but this effect is not very marked like on a Poco, this sensor unit is composed of a sensor main (Omnivision), a secondary ultra wide angle sensor (Sony), a portrait sensor (Omnivision) and finally a macro sensor (also Omnivision). Even if the photo sensors are not the same as on the Redmi Note 10, the optical unit uses the same type of format. [b][b]
The screen occupies 83% of the front panel, borders are visible but they are quite comparable to other models of the brand in this price range. The screen is interrupted by a photo sensor in the form of a punch, here too it is quite classic, the punch is quite visible but not annoying. [b][b]
Below we find the usual elements such as the usb type c port, the audio jack connector and a speaker. The Redmi Note 10s produces stereo sound, the other speaker is located at the listening speaker. [b][b] The Redmi Note 10s does not shine with its originality but it offers a really good level of finish for this price range, it assumes an entry-level character without neglecting its exterior appearance.[b]


[b]The information below comes from the Device Info HW application. The application provides detailed technical information about the tested phone. I bought the 6Gb / 64Gb version and you will find all the technical characteristics of the phone on the following screenshots. [b][b] Here are the peculiarities I noticed compared to the Redmi Note 10: [b] - The Redmi Note 10s uses the same screen [b] - The Redmi Note 10s uses the same fingerprint sensor [b] - The Redmi Note 10s offers 2Gb more RAM [b] - The wifi chipset is completely different and you will see in the rest of this test that this is a good thing [b] - The GPS of the Redmi Note 10s uses a Mediatek chipset which offers better accuracy than other brands [b][b]

CPU / GPU Performance

[b][b]Xiaomi does not seem to want to bind itself to a particular manufacturer for its CPUs and GPUs, some models are equipped with Snapdragon processors and others with Mediatek processors. What does this change for the consumer? Not much because these processors offer more or less the same performance with sometimes some pure performance differences and sometimes better energy management. The most visible factor of difference between these two families of processors is the precision of the GPS where I have never obtained a precision below 3 meters with a Snapdragon whereas with a Mediatek, I obtained a level precision of 1 meter. The Redmi Note 10s is equipped with a Mediatek processor, so I would expect the GPS performance to be better than the Redmi Note 10 Pro. [b][b] For the graphics part we find the same two families of GPUs with on one side the Qualcomm Adreno and on the other the ARM Mali, the Redmi Note 10s uses an ARM Mali G76 that the 'we also find in other phones like the Huawei P30, Redmi Note 8 Pro, Realme 6 and many more. It is therefore not a last generation GPU but it offers a good level of performance for a majority of users.[b]

Benchmark Antutu/3DMark

I got a score of just over 276,000 points with Antutu, this score puts the Redmi Note 10s above the Redmi Note 10 and below the Redmi Note 10 Pro. The Redmi Note 9T and the Samsung Galaxy A52 are other examples of phones that are very similar in performance. [b][b] With such a high score, the Redmi Note 10s will give you a comfortable everyday experience and you can even play most of the games without having to make too many sacrifices on the level of graphics. Only more greedy games like Fortnite will be a little less fluid. [b]

Note: this ranking only contains the phones I tested as well as a few others that I added for reference.
[b]Gaming[b]To test the performance in game, I download the mobile PUBG game and evaluate the in-game experience, graphics level and depth of vision. This game is quite demanding and should help you evaluating the performance of a phone. I was able to use UHD and HDR mode on PUBG Mobile with the Redmi Note 10s, this is the first time these options have been available for a phone in this price range. The experience is generally very good but the application I use to record the videos did not record the video with a sufficiently high FPS, it gives an impression of display delay but in reality there is none. not. The experience for this kind of game is therefore more than satisfactory.[b]

Network performance

The Redmi Note 10s is not 5G compatible but I wouldn't be surprised to see a 5G version appear later this year. For 3G / 4G frequencies, the Redmi Note 10s offers good frequency coverage that will allow you to use it anywhere in Europe.[b]
Choose your country to check if your phone is compatible:

The frequencies displayed below will allow you to see if this phone is compatible with your operator or if you will be able to use it in the country where you are going on vacation.

Signal 4G (before december 2020)[b]The ability to pick up the network correctly is an essential element for a phone but it is only very rarely measured. To measure a phone's ability to pick up the network, I perform a large number of measurements on the same cells to be able to compare phones under similar conditions. The signal is measured in dBm, a value of -90dBm indicates a worse signal than -70dBm. These measurements are therefore taken under real conditions and not in a laboratory, they are not scientific but give a good indication of performance. [b][b]Network signal sensitivity rating

[b][b]Signal 4G (from December 2020)[b]I decided to change the methodology for measuring the network because I noticed that the configuration of the mobile network changes over time. This makes it more difficult to compare phones because the conditions are no longer exactly the same.[b][b]To overcome this problem, I set up a device that captures 24 hours a day about ten parameters from the mobile network (ex: cell id, rssi, rsrq, snr, frequency,...). I then place the phone next to the device for 24 to 48 hours taking the same measurements so that I can compare them. [b][b] Overview of the phones tested with this methodology[b][b]

[b][b]I performed 957 measurements in 4G to assess the network sensitivity of the Redmi Note 10s and unfortunately Xiaomi took a step back because the sensitivity of this phone is significantly lower than the best Xiaomi I have tested over the past 6 months. On the whole test, I got a difference of more than 5 dBm between this phone and my measuring device where the Redmi Note 10 got a score very close to the measuring device. [b][b] On the following graph, we can clearly see that this phone never manages to match the sensitivity of my measuring device:
The score is however not as bad than with a Poco X3 but in this price range, the Redmi Note 10 and the Redmi Note 10 Pro do better.[b][b][b]Download/Upload speed[b]To test the download speed, I have identified some 4G cells offering good performance where I test all my devices several times to see what download and upload speed they can achieve.[b]Top 10 - speed ranking in download

Position of this smartphone in the ranking:0/30

Note: the theoretical maximum speed of a telephone is often limited by the configuration of the mobile network and the congestion of the network at the time of the measurement. So maybe you could get a higher speed on another network

Wifi performance

To test a phone's ability to receive the network properly, I take measurements near my router and then remotely (and always at the same place). This gives me an average in dBm where a value of -90 dBm indicates poorer performance than a value at -30 dBm.[b]
Wifi signal[b]I measured a signal of -17 dBm near the router and -67 dBm at a distance, these are good values, they are exactly the same values I got with the Redmi Note 10 while the Redmi Note 10s uses another wifi chipset. The difference between these two phones will be more visible in the download test. The Redmi Note 10s therefore offers good wifi sensitivity.[b][b]Top 10 - wifi sensitivity ranking

Note: I have a 400Mbps line and a modem capable of delivering higher speed, but I can never be sure how much bandwidth is available when doing a test.

GPS performance

[b]To test the quality of the GPS signal I use the Offline Maps application and I make the same train trip in pedestrian mode. Why? In pedestrian mode, the GPS does not artificially correct the signal to stick to the road, it has no markings, so you can see the actual position. I then use an application to measure the accuracy of the signal. The Redmi Note 10s uses a Mediatek GPS chip, chips from this brand usually offer a higher level of accuracy and this is the case again for this phone as I get accuracy at 1m outdoors and this accuracy drops to 2-3 meters in the car or behind a window.[b][b]Top 10 - GPS accuracy ranking

Position of this smartphone in the ranking:0/44

Note: An accuracy of 3 meters or less can easily be corrected by a good GPS application. Phone performance also plays a role in how fast your display updates, so good accuracy could be compromised by too slow a display.

Battery range

The Redmi Note 10s is equipped with a 5000 mAh battery, this type of capacity has almost become a standard at Xiaomi. The battery charges fairly quickly (161 minutes) but at the end the last 10 percent take longer. It takes about 35 minutes to reach 20%. [b][b]
I measured an autonomy of 636 minutes with the screen at 100% and 1556 minutes (a little over 25 hours) with the screen at 50%, l he autonomy is not linear and when the screen is at 100% brightness, it consumes 2.48 times more energy than at 50%. This battery life is good and comparable to most Xiaomi phones in this price range. It will allow you to last about 3 days using normal use and between one and two days in more intensive use (unless you play for hours with the screen at 100%).

Photo camera test

To test the quality of photos produced by a phone, I do a technical test (resolution, sharpness, chromatic aberration,...) in studio (identical conditions) to evaluate the technical part objectively. From the second half of 2020, I built my own laboratory to take completely objective technical measurements. I then take pictures in real conditions to see how the camera performs. I then evaluate these photos according to my criteria but I publish the photos so that you can evaluate the result according to your criteria.[b]


The Redmi Note 10s is equipped with a Samsung GW3 48 Mpix sensor. I had the opportunity to test this sensor in the Xiaomi Mi 11 Lite and I was positively surprised with the result. I have not yet finished my technical tests of this sensor but I see in particular that it offers better color rendering than the Redmi Note 10 Pro which is however supposed to offer better image quality. The Redmi Note 10s is the cheapest Samsung GW3 equipped phone at the moment. [b][b] For the ultra wide angle part, the Redmi Note 10s takes over the Sony IMX 355 which I tested in at least 5 other phones this year. The quality of ultra wide angle sensors is inferior to the quality of wide angle sensors but this Sony IMX 355 is doing quite well.[b]Default app[b] The default photo app of the Redmi Note 10s is the same as on most phones running MIUI 12, I didn't notice any change on MIUI 12.5. The settings at the top of the screen are easy to use and read thanks to the use of the black background, those at the bottom of the screen are still and always superimposed on the image which makes them absolutely unreadable when the scene is very bright.[b][b]

Photo quality

Photo test / studio[b]
I had not yet had the opportunity to test the Omnivision OV64B sensor, Xiaomi usually uses Samsung or Sony sensors. I took pictures with this sensor and the ultra wide angle sensor by browsing all the available modes (normal, AI, HDR, AI + HDR, Pro, night, ...). In normal mode, the Omnivision sensor produces underexposed photos, which is almost always the case when I take photos in the studio. I had to increase the exposure time by two notches to get the correct brightness. The sharpness is very good in the center, but the area of sharpness is very narrow. The graduated vertical line on the color checker is very sharp, but the Google logo on the rubix cube is already in a less sharp area. The fact that the subject is so close to the phone tends to exacerbate the problem, it remains to be seen whether this sharpness problem will still be present for outdoor photos where the subjects are further away. I'm going to do a separate technical test for color accuracy because with the underexposure of these photos, I can't really form an opinion. [b][b] The ultra wide angle sensor is a Sony IMX 355, it is the most used ultra wide angle sensor at Xiaomi this year. I have already tested it at least 5 or 6 times this year. This type of sensor always produces photos of lower quality than the main sensor, but in this range of sensors, the Sony IMX 355 is undoubtedly one of the best sensors. The studio test shows that the Sony manages exposure better than the Omnivision sensor, there are obviously large deformations but this is normal, this sensor is not designed to take close-up photos. The sharpness in the center is a little worse than that of the Omnivision sensor and it is normal for this kind of sensor but the area of sharpness is wider than with the Omnivision sensor. [b][b][b][b]Photo test / sunny[b]
Main sensor: Omnivision OV64B I haven't tested many Omnivision brand sensors and the ones I tested were rarely good cameras. So I had a little apprehension before testing this Redmi Note 10s and unfortunately my intuition was good. Before going into the details of this analysis, I will first reframe the context. The Redmi Note 10s is sold between 150 and 200 €, in this price range there are smartphones equipped with sensors such as the Sony IMX 582 or sometimes even the Sony IMX 682. The competition is therefore tough and to be able to compete with these cameras. , we have to set the bar high enough. [b][b] I chose this first photo because it illustrates quite well what this Omnivision sensor is capable of doing. I took this photo under the sun, the light was good. The first thing that strikes me are the colors, they are bland and the photo lacks contrast. The AI mode corrects this but sometimes forcing the colors to an unreal saturation. The dynamic range is not very wide either because the sky is very clear and the clouds are not very well drawn. The sharpness is fairly average, the foliage quickly loses sharpness. [b][b] I took a photo at the same time with a phone using a Sony IMX 682 and this is what it looks like: [b]
The framing is slightly different but there is only a few seconds of difference between these two photos. [b][b] The Omnivision sensor of this Redmi Note 10s therefore does not reach the level of the competition and for a little less money the Redmi Note 10 or the Poco X3 do better. Secondary sensor: Sony IMX355
The Sony IMX 355 is an "old acquaintance", I have tested this camera on many other phones and among ultra wide-angle sensors are without doubt one of the best. It produces images with all the faults of sensors of this type but these faults (smoothing, blurring, distortion, chromatic aberration, etc.) are less pronounced.

Video quality

Stabilisation[b] I haven't yet tested many entry-level smartphones capable of stabilizing 4k video and it's not the Redmi Note 10s that will change the situation. Stabilization in 4k is not effective, the shocks of walking are very visible and are not sufficiently damped.[b]Video normale conditions The Redmi Note 10s is capable of filming in 4k 30 FPS like most phones in this price range. The result is unfortunately not at the level of other Xiaomi models such as the Redmi Note 10 or the Poco X3. The colors are dull, the dynamic range is not very wide and the exposure jumps are very noticeable while this phone is good enough to avoid this kind of problem. The sharpness is not exceptional either, it is the kind of quality that would have been acceptable a year or two ago but today we find much better for the same price.[b]Video low light[b]Not yet available / tested[b][b]

Audio quality

To test the quality of the phone's audio output, I connect the device's audio output to a measuring tool, then play sounds on all frequencies and measure the differences between the original sound and the sound produced by the phone. In this way I measure the phone's ability to correctly reproduce all sounds.[b]
Frequency Response[b]This test is intended to test the device's ability to correctly reproduce all frequencies. The white line in the middle of the graph is the ideal situation and the other colors come from tests on different phones. A deviation from the reference line indicates a deviation from the ideal situation. To see good sound at all frequencies, it is therefore necessary to get as close as possible to the reference line.
I compared the Redmi Note 10s with the previous model (Redmi Note 9s) and I can see a very marked improvement in the sound quality. The Redmi Note 9 did not reproduce sounds well on all frequencies, its performance was erratic. The Redmi Note 10s does not have this problem and is moreover able to cover a wider frequency range, the highs deviate quite quickly from the norm, however, the sound will therefore lack finesse.[b]Dynamic Range[b]This test is designed to test a phone's ability to play sounds at different volume levels. Here too, the phones must be as close as possible to the reference.
The Redmi Note 10s produces a powerful sound with a limited level of distortion, the power is comparable to other Xiaomis that I have tested recently, Xiaomi has undoubtedly re-used the same speakers on several models. The volume level as well as the low distortion is quite comparable to other Xiaomi phones in this price range.[b]Noise Level[b]This test aims to identify if the device under test is able to reproduce sounds without too much noise. A high score indicates a low parasite rate, a lower score indicates a higher presence of parasites.
I did not notice any interference with the Redmi Note 10s, the sound behaves significantly better than the Redmi Note 9s, this new model of the S range is therefore much better than its predecessor but ranks in the average of other phones in the same price range.[b]

Screen quality

To test the screen, I use a colorimetric probe that measures the color accuracy of a screen, as well as other parameters to see if a screen is able to correctly reproduce an image. I also test the brightness level to determine if the screen will be able to display an image in full sunlight.[b]
The Redmi Note 10s uses the same screen as the Redmi Note 10, yet I got a slightly higher dE (even in standard mode). I got a dE score of 2.78 with this phone, it's a good score but Xiaomi calibrated this screen less well than on the Redmi Note 10. A priori the difference should not be visible to the naked eye because with a dE below 3, we do not really perceive the differences. The white on the other hand is very white, the temperature of the white is almost perfect and the black is very black thanks to the use of an amoled screen.[b][b]Top 10 - ranking of the best screens by colorimetry
1. Poco X4 Gt dE = 0.6
2. Xiaomi Mi 10 Lite 5g dE = 0.73
3. Xiaomi Mi 10t Pro dE = 0.83
4. Redmi Note 11 dE = 0.91
5. Redmi Note 12 Pro dE = 0.97
6. Google Pixel 6a dE = 1.01
7. Google Pixel 5 dE = 1.11
8. Realme Gt dE = 1.17
9. Redmi Note 12 dE = 1.17
10. Xiaomi Mi 11 Lite dE = 1.19

Number of smartphones in the ranking:75
Position of this smartphone in the ranking:0/75

Note: the colorimetric difference is measured in dE. After three, the human eye will perceive a colorimetric difference, so the dE should be the lowest. The tests were all carried out with a colorimetric probe.
[b]Brightness / Contrast[b]I got a very high brightness level on this Redmi Note 10s, I measured a brightness of 729cd / m² in sun mode, it's really a lot. I got a similar score with the Redmi Note 10, such a brightness level will allow you to use the phone in direct sunlight. [b][b] Xiaomi was the first to bring amoled screens below € 200 and the Redmi Note 10s also benefits. The use of amoled offers almost infinite contrast and therefore in this price range, the screen of the Redmi Note 10s is undoubtedly one of the best.[b]


The Redmi Note 10s uses a side fingerprint sensor like on most Xiaomi phones released this year. This fingerprint sensor works really well to such an extent that when I have to test a phone with another type of sensor (ex: under the screen), I tend to turn it off.[b]

Operating system

[b] The interface of MIUI 12.5 has not changed much compared to the previous version. The setup screens have been embellished but that doesn't fundamentally change the experience. The new features are not immediately obvious because they are mainly functionalities that have been improved. [b][b] What's new? [b] - launch of MIUI +: this feature allows you to associate your phone with your computer as offered by Samsung with Samsung Dex. The association is done by a QR code but I think the Redmi Note 10s does not have access to this feature because I did not see it in the settings [b] - security reinforcement, it is by possible example of running an application in a sandbox to prevent a poorly kept application from end up infecting the rest of the system. [b] - a new note-taking tool with the ability to draw [b] - new sounds, live wallpapers [b] - reduced power consumption [b][b]

Compare Xiaomi Redmi Note 10s with the others

I assigned a score of 1 to 10 for each test that determines the strengths and weaknesses of a product. I am using 0 for criteria that have not (yet) been tested. A score of 1 to 3 indicates poor performance (and yes, it does), a score of 4 to 6 indicates average performance, a score of 7 to 8 indicates good performance, and a score of 9 and 10 indicates exceptional performance. .
The score is calculated based on my measurements and when there are no measurements, it is a subjective opinion based on my experience.

The scores are not static, they change over time because the performance of new products changes and this must be taken into account.

Test / Review conclusion

[b]I tend to trust Xiaomi and I often buy their smartphones without having read any reviews on the internet. In most cases it goes well and there are cases where unfortunately Xiaomi takes a wrong step. Xiaomi has flooded us with so much new models this year that the competition among the various Xiaomi models is stiff and you have to compare Xiaomi with Xiaomi first before looking at what is being done elsewhere. The Redmi Note 10s is not a bad phone but it does not compare with other Xiaomi phones in the same price bracket, I am thinking in particular of the Redmi Note 10 or the Poco X3 (or even the Poco X3 Pro depending on the price). 'possible promotions). [b][b] The Redmi Note 10s has a price / performance positioning and in this game, it comes out a winner if we limit ourselves to the Redmi range. As soon as you look across the wall at Poco, you quickly find yourself with more fierce competition. I imagine not everyone is a fan of the Poco design and this Redmi Note 10s might find its place among those looking for low-cost performance without the Poco gamer-type identity. The Redmi Note 10s has a good amoled screen, this also distinguishes it from the Poco which is limited to an IPS screen. Unfortunately, I cannot give it more positive points compared to the Poco. [b][b] The photo part of this Redmi is clearly not at the level of what Xiaomi usually does and as it is an important purchase criterion for many buyers, I recommend looking instead on the side of the Redmi Note 10 (see my test) or even the Poco X3 (with or without Pro). The other weakness of this phone is the sensitivity to the 4G network, it is below average so if there are any of you who use their phones for phones (yes it still happens), the Redmi Note 10 does better. . [b][b] Apart from performance, design and screen, the rest are pretty average. The sound is good without being extraordinary, the GPS signal is average, the battery is average, ... In short, I will not spend too long on this phone, I have seen more positive tests on this phone and I do not understand so I let you judge for yourself the quality of the photos as well as the other points that I put together in this test.[b]Strengths[b]- finish [b] - performance [b] - screen [b] - correct battery life [b] - wifi download speed [b][b][b]Weaknesses[b]- network sensitivity in 4G [b] - photo / video quality [b][b][b]Alternatives to this product[b][b]If performance is not a priority for you, I would recommend the Redmi Note 10 instead. If performance is important, the Poco x3 Pro will do much better in performance but also for many other points.[b]
