About DXOMARK Battery tests: For scoring and analysis in our smartphone battery reviews, DXOMARK engineers perform a variety of objective tests over a week-long period both indoors and outdoors. This article highlights the most important results of our testing. (See our introductory and how we test articles for more details about our smartphone Battery protocol.)
Sub-scores and attributes included in the calculations of the global score.

- Reaches an 80% charge in only 52 minutes
The Xiaomi Redmi Note 10S comes with a better chipset, a more powerful charger, an FHD vs HD screen, and more RAM than its rivals in this comparison, the Realme C21 and the Vivo Y20s, also in the Essential category. The table below shows the battery capacity, charger, display type and resolution, and processor specifications for all three devices.

How long a battery charge lasts depends not only on battery capacity, but also other aspects of the phone’s hardware and software. The DXOMARK Battery autonomy score is composed of three performance sub-scores: (1) Stationary, (2) On the go, and (3) Calibrated use cases. Each sub-score comprises the results of a comprehensive range of tests for measuring autonomy in all kinds of real-life scenarios.
The Xiaomi Redmi Note 10S’s autonomy performance is slightly above average for this segment
A robot housed in a Faraday cage performs a set of touch-based user actions during what we call our “typical usage scenario” (TUS) — making calls, video streaming, etc. — 4 hours of active use over the course of a 16-hour period, plus 8 hours of “sleep.” The robot repeats this set of actions every day until the device runs out of power.
The Redmi Note 10S lasted almost 3 days during our TUS testing, outlasted by the Vivo Y20s, which also did better at night management.
On the go
Using a smartphone on the go takes a toll on autonomy because of extra “hidden” demands, such as the continuous signaling associated with cellphone network selection, for example. DXOMARK Battery experts take the phone outside and perform a precisely defined set of activities while following the same three-hour travel itinerary for each device.
The Xiaomi Redmi Note 10S put in a weak performance in all our on the go tests, with below-average results for a device in its price range, and coming in l ast among its rivals for call, navigation, and camera.
For this series of tests, the smartphone returns to the Faraday cage and our robots repeatedly perform actions linked to one specific use case (such as gaming, video streaming, etc.) at a time. Starting from an 80% charge, all devices are tested until they have expended at least 5% of their battery power.
The Redmi Note 10S beats its rivals in here, showing d ecent idle time management, impressive performance for 4G video streaming, and above-average results for all calibrated tests.
The DXOMARK Battery charging score is composed of two sub-scores, Full charge and Quick boost. Full charge tests assess the reliability of the battery power gauge; measure how long it takes to charge a battery from 0% to 80% capacity and from 80% to 100%; and measure how long and how much power the battery takes to go from an indicated 100% to an actual full charge. With the phone at different charge levels (20%, 40%, 60%, 80%), Quick boost tests measure the amount of charge the battery receives after being plugged in for 5 minutes.
Thanks to its 33W charger, the Xiaomi Redmi Note 10S easily comes in first among its competitors here.
It takes the Xiaomi Redmi Note 10S 52 minutes to go from empty to an 80% charge, and 1 hour 30 minutes to fully charge. It takes the Realme (10W charger) 3 hours 07 minutes and the Vivo (18W charger) 2 hours 28 minutes to achieve a full charge.
One drawback for the Xiaomi device is that when its gauge first displays 100%, it’s actually only 92.9% full, requiring another 22 minutes to fully charge.
Users who plug in the Redmi Note 10S for 5 minutes will gain an average of 4 hours 27 minutes of autonomy, which is 3 hours more than the Realme and 2 hours more than the Vivo.
|Xiaomi Redmi Note 10S||Realme C21||Vivo Y20s|
|Autonomy boost (hh:mm)||20%||4:36||1:25||2:45|
|Percentage boost||20%||9.5 %||3.7 %||5.5 %|
|40%||9 %||3.7 %||5.2 %|
|60%||8.8 %||3.8 %||5.1 %|
|80%||6 %||3.4 %||3.5 %|
|Energy consumed||20%||2373 mWh||1049 mWh||1508 mWh|
|40%||2250 mWh||1063 mWh||1425 mWh|
|60%||2197 mWh||1087 mWh||1387 mWh|
|80%||1496 mWh||981 mWh||962 mWh|
Our Efficiency score comprises two sub-scores, Charge up and Discharge. Charge up is the efficiency of a full charge (how much energy is drained from the wall outlet vs the energy capacity of the battery, as well as the efficiency of the charger and its residual consumption). Discharge is how much current the smartphone drains from the battery when in use (the ratio of battery capacity over autonomy). Better autonomy with a smaller battery means better efficiency.
Redmi Note 10S Review
Now more than ever a phone’s display is a make or break factor. As we all use our phones for watching videos or Netflix, taking photos and even gaming, we want to be viewing them in high quality. Thankfully, the Redmi Note 10S‘ 6.43” AMOLED DotDisplay is crisp and bright, bringing out vibrant colours. I put this to the test by watching some 4K videos on YouTube, and the phone had no problem with accentuating the high quality. The screenshots obviously can’t do it justice but hopefully give you some examples.
A higher brightness can drain the battery quicker as with all phones, and you may be concerned about eye strain. Not to worry though, as you can turn on dark mode or even schedule it for the times your eyes need resting. There’s also a reading mode, adjusting to warmer colours and textures to reduce either blue light or eye strain. Anti-flicker mode also reduces flickering in low light conditions.
I was extremely impressed by not only the brilliant display but the variety of options to help your eyes, particularly as someone who often has to wear blue light glasses.
Lights, Camera, Action
For shutterbugs out there, the Redmi Note 10S is more than readily equipped to satisfy that need. With a 64MP main camera, an 8MP ultra wide camera, a 2MP depth sensor and a 2MP macro camera, the result is clear photos in a range of environments. However the night mode wasn’t too great when I tried it out late at night, only making it a little brighter. Though, I imagine it would work well with somewhere like a fireworks show with more light against the dark, or somewhere quite dim.
You could get some really nice depth of field adjusting the shutter in portrait mode, as well as add a camera filter. An option I really liked was the 2x zoom, which allowed for a closer image without losing the quality. The wide angle lense also offered a much larger view for those photos where you just can’t fit everything in.
Filming up to 30FPS in 4K was also a pleasant surprise for a phone of this price range. Add in the option to do slow mode videos, time lapse and a variety of pro camera options, and you can’t really ask for much more!
Though perhaps not a priority for everyone, the ability to play games on the go is important here at Rapid Reviews. The Redmi Note 10S has you covered though, with a processor that ensures “a CPU clock speed of up to 2.05GHz, and a GPU clock speed of up to 900MHz.” I decided to put this to the test playing Dead by Daylight Mobile, since the PC version is one of my favourite games.
Though not the most graphically challenging game (that’s a whole other review), it does have online play. I was concerned about dropping frames or lag especially in this game where you have to act fast. Thankfully, I experienced none of this at all and everything ran smoothly.
The bar at the top of the screenshot above could be brought out by swiping from the top left corner of the screen. Here, you could see how your game was running as well as access some neat features. This included being able to screenshot or start screen recording at the touch of a button, which is great for sharing clips. Or, you could quickly switch over to other apps like your internet browser or Game Turbo is perhaps not an interest to everyone, but it’s certainly worth mentioning for gamers and I appreciated it myself.
I rely on my phone to last me throughout the day like many of us, so battery life is one of the most important things in a phone. The Redmi Note 10S claims to have 33W fast charging, with the device reaching 54% in 30 minutes. I kept an eye on my first time charging it from around 10%, and to full charge it took under two hours. I think this is perfectly reasonable, particularly when it lasts as long as you can see in the image below!
Of course though, various factors affect the battery life. I got to put it to the test while on a day out, and my partner wanting to use it to watch the football using data. Despite being on for a good couple of hours, it lasted significantly longer than his own Samsung Galaxy.
So, is it time for you to upgrade to the Redmi Note 10S? I believe it’s a great mid-range phone with a surprising amount of high-end features, such as game turbo and camera quality. It is well worth the money and honestly rivals the more expensive (or overpriced…) phone brands such as the iPhones. If you’re someone who uses Android phones you’ll feel right at home with the OS which is easy to use. There are also some cool themes to use to personalise your phone, both paid and free, for example I used a more minimalist free theme!
Though I hadn’t heard much about the Mi range of phones before, they should definitely be on your radar. For the Redmi Note 10S, it’s a fantastic choice for a mid-range phone that isn’t brimming with premium features you’d have to pay a lot more for, but goes above and beyond what you’d expect.

Xiaomi Redmi Note 10S Review: Decent Mid-Ranger Outshined By Its Pro Variant
The Redmi Note 10S is the company’s latest budget offering in the smartphone entry-level segment. It is also the fourth device in the Redmi Note 10 series, priced in between the Redmi Note 10 and Redmi Note 10 Pro. While being a budget device, the Note 10S doesn’t slouch when it comes to its hardware offerings. With that said, let’s check out the phone’s specs.
Redmi Note 10S – Specifications
|Model||Redmi Note 10S|
|CPU||MediaTek Helio G95 Processor|
|Storage||128GB UFS 2.2|
|Display||6.43-inch AMOLEDFHD Resolution|
|Rear Camera||64MP Wide Main Sensor8MP Ultra-wide Angle Sensor2MP Macro Sensor2MP Depth Sensor|
|Front Camera||13MP Main Sensor|
|Battery||5,000mAh Battery33W Quick Charging|
|Connectivity||Dual-Band Wi-Fi 5LTE ConnectivityBluetooth 5.0|
The Redmi Note 10S has a very similar design to the Redmi Note 10 Pro, but the back instead has a glossy, reflective surface, which can also be quite the fingerprint magnet. If you don’t want the smudges to show that much, you might want to slap on a casing (provided in the box, which is nice). The camera bump is also thinner, and has a slight angle increasing from the flash module to the lenses.
On the left, you have the SIM tray slot, while the right side has the volume buttons and the power button which has the fingerprint sensor embedded right in. The top has the speaker grille, and IR blaster, while the bottom has the 3.5mm audio jack, USB Type-C port, and the additional speaker grille to create a stereo speaker system.
The selfie notch is right in the top middle of the screen, and the bezels are quite minimal except for the bottom chin. The phone has a standard candy bar design, and nothing much to shout about.
The Redmi Note 10S features a large 6.43-inch FHD display with an AMOLED panel. That’s right, an AMOLED panel, which offers better visual quality and battery life management. The display gets really bright even under harsh/direct lighting conditions, and the screen is still very visible. Auto-brightness sensor is a little aggressive, but that can always be rectified through OTA updates.
Display quality wise, colours are vivid but tend to be on the warmer side for me. Blacks are fairly black, but the experience is still great when watching movies or playing games. With the 20:9 aspect ratio, movies look particularly good as it somewhat removes the black bar on the top and bottom of the screen. You can maximize the video to fit the frame, and that would improve the overall viewing experience.
It’s unfortunate there’s no 120Hz or even 90Hz refresh rate on the display, but the AMOLED panel should be more than able to make up for it. This is a budget device after all, so they had to sacrifice certain aspects.
Can’t believe i’m saying this, but the Redmi Note 10S feels a little too thin (8.29mm) for me. It does provide a good grip in my hands, but I still prefer if the phone was slightly thicker. Maybe some of you would appreciate how thin it is, but not for me. It does have the right amount of weight (179g), and to protect the phone further, it even has IP53 dust and water resistance with Corning Gorilla Glass 3 for screen protection. This is a feature that’s seldom seen on smartphones of this price range.
The phone’s 3.5mm audio jack can be a hindrance when I’m watching a movie or playing games while my earphones are plugged in. So, it’s better to just use a TWS earbuds instead for a more pleasurable experience. It would be more natural if the volume and power button can be positioned slightly lower, as I’ll need to reposition my palm up and down to reach them.
The 33W charger and transparent casing provided in the box is also a bonus, allowing you to get set up right away without needing to source for another charger or third party casing.
Packed with a MediaTek Helio G95 processor paired with 6GB of LPDDR4X RAM and up to 128GB of UFS 2.2 based storage, the device does offer decent day-to-day performance. In terms of app management and multitasking, it serves up great performance with very little hiccups. But when it comes to navigation, you can definitely feel the 60Hz refresh rate kicking in, but that’s mostly cause I’ve been used to 90Hz and above. If you’ve never used anything above 60Hz, this display wouldn’t be a problem for you.
Thermal wise, I’ve only felt a slight warmness in the camera bump region, especially when the phone is handling more intensive tasks like playing games or longer sessions of photography and videography.
Here are the benchmarks we ran for the Redmi Note 10S, except 3DMark:
In terms of camera, the Redmi Note 10S has a quad camera system on the rear, which includes a 64MP wide angle main sensor, an 8MP ultra-wide angle sensor, a 2MP macro sensor, and 2MP depth sensor for better bokeh/portrait shots. The UI is pretty easy to work with, but unfortunately, the macro mode still requires several taps to get it to work right.
Image quality wise, photos taken in daylight tend to look oversharpened. You’ll get nice details in your image, but objects that are further away can look a little blotchy. Weirdly enough, photos taken with the 64MP mode, they have low detail and aren’t as sharp as the pixel-binned ones. If you were using the ultra-wide angle sensor, images are alright, but there are some noticeable distortion on the sides.
Macro shots with AI turned on performed better as the phone could capture FOCUS faster. Portrait shots also allowed me to select the amount of blur i wanted before taking the shot. Macro shots are great, but limited to a maximum 2MP resolution.
When it comes to night shots, they appear flat and grainy. However, once you turn on Night Mode, the images start to look better as they turn brighter with better details, and highlights. Do refrain from using the ultra-wide angle sensor at night, as it doesn’t offer the best picture quality. It’s better used for day shots instead.
Selfies are decent, and since I don’t take selfies as often, I do not have much Комментарии и мнения владельцев on them. Background blur and beautification can be manually adjusted before taking the shot.
Here are the photo samples taken with the Redmi Note 10S:
In the audio department, the speakers do a great job at offering the stereo sound effect. The highs are bright, and the mids are splendid, but it does lack in bass. Volume wise, the device can get really loud with little distortion at 100%. But, you can feel the speakers vibrating on the back of the device. So, the sweet spot for me is actually at the 80% volume mark where you’ll get decent audio performance with no vibrations.
The Redmi Note 10S has a 5,000mAh battery, just like the standard Redmi Note 10. It is also coupled with the 33W Quick Charger provided in the box. On a single charge, I could use the phone for more than a day, and I didn’t notice any abnormal battery drain either.
Charging the device from zero to 50% took about 45 minutes, while a full charge took about an hour and 18 minutes.
The Redmi Note 10S is a great device that not only looks good, but is a great daily driver for those who are on a budget. Sure, there’s no 5G onboard, or 120Hz refresh rate, but you’re still getting a great deal from the AMOLED panel, more than capable Helio G95 CPU, and 5,000mAh battery.
For the price, it’s really hard to not recommend the Redmi Note 10S if this falls into your budget range. If 5G is something you’re after, then you could consider the standard Redmi Note 10 5G.
Xiaomi Redmi Note 10S Review – Economic And Strong
Just because you’re not feeling the 5G hype, doesn’t mean you don’t deserve a better phone, says the Redmi Note 10S. With its compact design and economic price, the phone is here to make sure your options aren’t limited to choosing between the cutting edge of price function, versus a junker from the Clinton years.
But how does the phone stack up? Read on and find out.

The Feel of It
Just like its sister phone the Redmi Note 10 5G, the Redmi Note 10S feels pretty good in your hands. It’s plastic casing makes it incredibly lightweight, so you can carry it around without worrying about wearing yourself out over long periods of time.
I’m a big fan of the fingerprint-proof casing, which means you won’t have to worry about embarrassing photos where you can see the smudges on the back of the phone.
Where the phone really shines though is in its screen, which sports a 6.43 inch display at 2400 x 1800p. When you consider the size of the phone, this is basically one of the best functional viewing resolutions you can get, and even mundane YouTube videos look amazing on it.
The tradeoff here is that the screen has a low refresh rate of only 60hz, so don’t expect any high-intensity gaming out of it. It’s not too bad a tradeoff, all things considered- after all, a lot of console games are still in denial about wanting to be more than 30 frames per second, but considering even the Redmi Note 10 5G’s 90 hz screen, if you’re looking to game in style this probably isn’t the phone for you.
The Redmi Note 10 S comes with a quad camera, a feature usually reserved for higher-end phones. This allows you to take a variety of photos, with lenses tailored for different situatison.
The stand out workhorse is the 64MP main camera, letting you take gorgeous high-resolution photos to capture every detail. This should work for most every day use, since you’ll be able to capture regular shots gorgeously.
After that the next lens is an 8MP Ultra-Wide, letting you take gorgeous sweeping panoramas. This is a great lens to have on holiday, letting you take wonderful vistas with good clarity.
After that you have a 2MP Macro lens, meaning you’ll be able to take photos of whatever hobby you’ve been working on for the past year. It also comes with a 2MP depth sensor, so taking all manner of artistic shots is really possible with the Redmi Note 10S.
The front camera is no slouch too, with a 13MP camera that takes great selfies. The quality is also pretty decent if you wanted to use it for livestreaming, so this is definitely something to look into for budding content creators.
Like I mentioned earlier, the biggest bottleneck with the phone is its screen, which only caps out at 60hz refresh rate. I won’t hold it against the phone for much longer here, since there’s a lot more to gaming than a Game Genie window with a big number in the framerate section. After all, the Redmi Note 10 S runs the MediaTek Helio G95 chipset, which already runs the phone’s OS pretty well. On top of that it also has 6GB RAM, so it’s not like the phone wasn’t made for running games or anything.
One of the most popular mobile games, PUBG Mobile runs well on the phone, assuming you’re running it at lower settings. The game’s borderline unplayable on any of the higher settings, and you won’t be able to run the high framerate mode thanks to the screen’s refresh rate. The main praise here is for PUBG Mobile’s options, where there’s absolutely a setting that the Redmi Note 10 S can run the game flawlessly. It doesn’t look amazing, but it looks well enough and more importantly the only thing killing you will be your own lack of skill.
Similarly, we tried out the GamerBraves Mobile Testing Apparatus, Genshin Impact, and the results weren’t great either. Any attempt to get the game running on higher settings is met with a wonderful slideshow presentation, while you also discover the Redmi Note 10 S’s secret hand warmer function. Actually the heating issues kind of stays the same even in regular play, but at the very least the game is optimized well enough that you could kill some time in Genshin before doing your dailies on PC.
Admittedly, the Redmi Note 10 S isn’t really that great of a gaming phone. On one hand, it does the bare minimum- it can run games. But don’t expect to be taking glorious screenshots or having much to brag about performance wise, and do expect some nasty caveats to go with it.
At the end of the day, the Redmi Note 10 5S is one of those phones that seems like you need to really make an informed decision when it comes to buying. For its price point, the screen is great! But it affords good pricing and display quality by trading in a lot of other functionality, particularly when it comes to gaming.
As a mobile gaming site, it’s hard to not take that a little seriously, but again it all comes down to personal preference. If you’re the type who just plays auto battler gacha games, you’ll have no qualms- who cares about 90hz when your waifu looks gorgeous on an AMOLED screen? But if you’re the type who wants to climb to the top of mobile esports, maybe give this one a miss.
