The Redmi note 9 Pro focuses on delivering a value-for-money experience. While the competition pushes the barrier with specs, and price, the Redmi note 9 Pro sticks to lớn its formula of bringing great performance và good-enough imaging khổng lồ a price point that is within the reach of most buyers. The kết thúc result is a phone that delivers what it promises but ends up coming across as a tad boring.

The importance of the lưu ý series of phones in Redmi’s lineup cannot be overstated. It is the phone that put the company on the bản đồ and helped mi gain massive global momentum. The Redmi note 4 sold over 10 million units over its hàng hóa cycle, và last year, the Redmi chú ý 7 Pro was India’s highest-selling phone in the Rs. 10,000 and above category. Suffice it to say, it is critical for the brand to lớn get this product right.

Of course, the competition has been keeping a keen eye on Xiaomi’s rise and has mounted a strong counteroffensive. Realme is its strongest competitor yet & has built a portfolio of truly great products that match xiaomi mi spec-for-spec và sometimes beat it.

With that in mind, it is all the more important for Xiaomi khổng lồ build a sản phẩm that doesn’t just meet a checklist but pushes forward. Is the Redmi note 9 Pro that device? We find out in the Android Authority Redmi lưu ý 9 Pro review.

A newer version of this device is now available. The Redmi note 10 ups the ante in nearly every way including performance, a significantly upgraded design, và a much-improved 120Hz AMOLED display. Read our Redmi chú ý 10 Pro đánh giá for full details.
About this review: I wrote this Redmi lưu ý 9 Pro reviews after spending a week with the phone as my primary device. Xiaomi mi India supplied the device, which was running game android 10 with MIUI 11 on board.

Update, Aug 2021:The đánh giá was updated khổng lồ reflect fresh software updates, competition, và value for money.


Redmi chú ý 9 Pro (6GB + 64GB): Rs 13,999 (~$191) / £249Redmi cảnh báo 9 Pro (6GB + 128GB):Rs. 16,999 (~$232)/ £269Launched in March 2020, the Redmi chú ý 9 Pro brings with it an updated thiết kế language as well as all-day battery life. The phone is available in a range of colors including white, grey & a particularly fetching green.

The phone is part of the Redmi chú ý series, Xiaomi’s most popular smartphone lineup & includes a range of improvements including a faster Snapdragon 720G chipset as well as a bigger 5,020mAh battery.


Over the last year, mi has been championing its all-new Aura Balance design direction. The Redmi lưu ý 9 Pro is a direct extension of the thiết kế language introduced with the note 7 Pro, and then further iterated upon with the note 8 Pro.

The most distinctive, và different, kiến thiết element has to lớn be the back panel of the phone. Gone is the gradient & instead, you get a brilliantly glossy pane of Gorilla Glass 5. We have the Aurora blue variant and at the right angle, it could double up as a mirror in a pinch. Of course, this makes it a fingerprint and scuff magnet. Using the included case is almost necessary if you don’t want to constantly clean up smudges. It’s a shame really since the phone somehow manages khổng lồ stand out despite the myriad iterations on similar design principles.


Like the Redmi note 8 Pro, the camera module is centrally mounted. However, instead of a vertical arrangement, all four sensors are enclosed in a raised rectangular section with the flash placed below it. The raised module stands proud on the phone, though I found it catching on the pocket of my jeans a bit.


A big change this time around is the switch to a side-mounted fingerprint reader. It is integrated into the power nguồn key and I found it to lớn be extremely fast at unlocking the phone. The button is intuitively placed and very easy to lớn reach, even with a single hand. What is not-so-intuitive, however, is the unsegmented volume rocker. It is placed too far up so reaching it is nearly impossible without grasping the phone with two hands or awkwardly shuffling it around.

You will find a USB-C port along the bottom edge as well as a tai nghe jack. Over on the left is a combined slot for dual nano-SIM cards as well as a microSD card for memory expansion. Yes, the phone retains an IR blaster at the top.


Over on the front, things are less different. There’s a slightly bigger 6.67-inch display with a taller 20:9 aspect ratio và camera cutout for the front-facing camera. The resolution remains Full HD+ with the panel delivering punchy colors at the mặc định setting. However, compared lớn stablemate the Poco X2 và competitor Realme 6 Pro, the phone doesn’t pack a high refresh rate panel. While the benefits of a 90Hz or even 120Hz panel on a mid-range phone are debatable, there’s no doubt that this is a missed opportunity that puts the Redmi cảnh báo 9 Pro on the back foot compared khổng lồ its peers.

Overall, the Redmi note 9 Pro is a conservative, but pleasant step forward as far as aesthetics are concerned. I do have an issue with the sheer weight of the phone though. Clocking in at 209g, the note 9 Pro can get cumbersome lớn hold over long durations. No, the phone is not waterproof. However, it retains a P2i coating which should offer a degree of splash resistance.

The Redmi chú ý 9 Pro sees the company returning to lớn Qualcomm’s Snapdragon platform. While the note 8 Pro used a Mediatek Helio G90T, this time around the phone sports a Snapdragon 720G. The chipset sports a combination of two Kryo 465 Gold cores, as well as six Kryo 465 Silver cores. In addition, there is an Adreno 618 GPU tackling graphics duties.

As is the case with almost every mid-ranger these days, day-to-day performance is more than satisfactory. MIUI is well mated khổng lồ the hardware và delivers a polished, slick experience. There is no hint of lag or stutter, & we didn’t expect it either.

Depending on the variant you opt for, RAM may or may not be an issue. I’d advise gamers to lớn steer clear of the base version of the phone with just 4GB of RAM. In fact, it wouldn’t be the best choice from a future-proofing point of view either, if you plan to lớn hold on lớn the phone for a few years.

Despite being a mid-range chipset, the Snapdragon 720G is more than capable of powering through any app or trò chơi you throw at it. I was able to test out PUBG with the graphics turned up khổng lồ maximum without any noticeable stutters.

Big battery, slow charging

Xiaomi pioneered the trend of slapping large 4,000mAh batteries in phones, & the note 9 Pro takes it a step forward. This time around, the phone has a 5,020mAh cell that is more than enough for a long day of heavy use and then some.

The phone delivered over 6 hours of screen-on time in our torture test, but charging the Redmi cảnh báo 9 Pro takes time.

Putting the phone throughAndroid Authority‘s very own battery test that runs the Speed kiểm tra G torture kiểm tra on a loop, the phone delivered a respectable 6 hours và 22 minutes of battery life. Suffice it to say that you won’t be putting the phone through that kind of beating all day long. Unfortunately, charging speeds are limited to 18W and it took a good 140 minutes to đứng đầu up the battery from scratch.

Part of the reason mi manages lớn keep hardware prices low is its inclusion of software services and ads in the operating system. Running MIUI 11 based on android 10, things on the chú ý 9 Pro are the same as they’ve always been, for better or worse.

At its best, MIUI integrates a world of functionality and tweaks right out of the box. From being able khổng lồ tweak gestures, add themes, set rotating lock-screen wallpapers, to including a competent file manager and software to quickly nội dung files amongst other users, there’s a lot of nice additions here if you are not too fussy about a stock Android-like experience.

However, the sheer amount of third-party apps tossed in remains off-putting. The number of app inclusions seems khổng lồ be increasing with every successive release & not all of these can be removed. địa chỉ cửa hàng to that notification bar spam and it very quickly falls short of the experience you’d want from a new phone. Sure, you can dive into the settings và disable most of these apps, however, this is not something that should be expected from the majority of users.

Following the launch, the company has issued a range of updates. This includes regular security patches for February và March. The updates also bring in standard features like system performance, stability enhancements.

In May 2020, mi issued out a new MIUI update with the May apk security patch and no additional features.

To Xiaomi’s credit, the company has been quick khổng lồ roll out security patches. Early in July 2020, the company initiated the rollout of MIUI with the June security patch. No other features were added in. Later in September 2020, the company rolled out the all-new MIUI 12 update with September security patches. While it is still based on apk 10, it brings with it a whole host of features lượt thích a spruced-up control center, better controls for privacy protection, new animations, và much more.

Xiaomi has been plugging away with software updates lớn the Redmi lưu ý 9 Pro, và as of June 2021, the phone has received MIUI 12.0.5 with the May apk security patch. The update also adds in the xiaomi mi Cloud app.

The chip core camera set-up remains consistent between the Redmi cảnh báo 8 Pro và the all-new Redmi lưu ý 9 Pro. The quad-camera setup includes an 8MP ultrawide sensor, a 2 MP depth sensor as well as a rather questionable 5MP macro sensor. The primary shooter this time around, however, is a 48MP Samsung GM2 sensor. This is in contrast to lớn the 64MP camera in the previous model. Interestingly enough, xiaomi has introduced an even higher tier called the Redmi cảnh báo 9 Pro Max that sports the 64MP sensor as well as faster charging speeds.

The cameras on the Redmi note 9 Pro are, for lack of better words, okay. The good news is that mi has opted for very natural-looking color science here. More often than not, the màu sắc temperature và white balance are spot-on which is very good lớn see. The dynamic range isn’t too bad either with some, but not all details retained in the shadows. However, there is a certain softness to images captured with the lưu ý 9 Pro. I don’t mind the lack of oversharpening at all, but surface-level detail is missing in a lot of images.

On that note, despite pixel-binning images down khổng lồ 12MP, there is a lot of grain và noticeable noise when pixel-peeping, no matter the lighting conditions. In most cases, it isn’t really bothersome, but it becomes readily apparent when cropping into the frame.

If you like shooting ultra-wide images, or in portrait mode, the Redmi cảnh báo 9 Pro does a good enough job. Dynamic range is a bit limited when shooting with the wide-angle sensor and white balance can be ever-so-slightly off. However, the mode works well lớn capture a wide frame without much effort. Meanwhile, mi has done a particularly good job at optimizing the portrait mode và the phone does a fantastic job at edge-detection, creating a natural-looking blur.

There’s a 5-megapixel macro camera tossed into the mix, and it does the job. I’m not a big fan of a dedicated macro lens & would rather have a telephoto shooter instead. Still, if you want to lớn get up close & personal with your subjects, you have the option.

Night mode is, however, where the Redmi chú ý 9 Pro really flounders. Using the primary camera, images are horribly grainy with digital artifacts và splotches creating a nearly unusable shot. Things improve by a small degree when using the night mode functionality. Still, the image is far from praiseworthy & competitor Realme’s hardware blows away the lưu ý 9 Pro in this regard. Elsewhere, the camera does a reasonable job of capturing selfies from the 16MP front-facing camera. Hit the liên kết to see some high-resolution Redmi note 9 Pro camera samples.

Xiaomi has made improvements to lớn the clip mode as well. The camera captures crisp footage all the way up khổng lồ 4K, 30FPS though the exposure levels are consistently just a bit too high. Software additions have been made to appeal to nội dung creators, và include a cinematic 21:9 crop mode as well as built-in filters. In a cool-to-have-but-totally-overkill feature, the video clip camera lets you shoot straight-from-the-sensor log clip footage, which should make it much easier to màu sắc grade in software like Premiere Pro or Resolve :thinking_face:

As is the case with mid-range hardware, a headphone jack is part of the package. Audio output đầu ra from the Redmi lưu ý 9 Pro sounds good enough without any noticeable hiss. I plugged in a pair of 1More Triple Driver earphones và the audio output went loud enough & offered a decent amount of dynamic range. Not the most resolving output, but it should suffice in a pinch if you just want khổng lồ listen to lớn some tunes on the go. Speaker đầu ra is loud but lacking in bass. Dual stereo speakers would have definitely elevated the experience.

If you are planning to use bluetooth không dây headphones with the cảnh báo 9 Pro, the phone can output đầu ra over AptX, AptxHD, & LDAC so you are guaranteed to get high-quality audio as long as your headphones tư vấn the necessary codec.

Xiaomi"s phablet brings a greater focus on value and performance. The phone combines a Snapdragon 720G chipset with an excellent design, good enough optics to create a compelling package for anyone who doesn"t want to lớn spend too much.
Value for money is a key selling point for the Redmi cảnh báo series of devices. However, for the first time in years, the competition made me really think long và hard if the phone is truly delivering the best value possible. The Redmi chú ý 9 Pro starts at just Rs. 13,999 (~$177) for the base variant with 4GB RAM and 64GB storage và goes up lớn Rs. 16,999 (~$232) for the 6GB RAM và 128GB storage version. In Europe, the Redmi lưu ý 9 Pro is available starting from £249 in the UK and other markets for €269.

If flat-out performance at a low price is what you want, the Redmi chú ý 9 Pro still delivers decent bang-for-the-buck. The similarly priced Realme 6 saddles you with a Helio G90T chipset, và you’ll have lớn pay a lot more for the similarly specced Realme 6 Pro.

That said, if you are in the market for a new mid-ranger, you need to lớn take a closer look at the Redmi lưu ý 10 Pro. Priced a bit higher than the 9 Pro, the phone amps up the specs with a 64MP primary camera, a Snapdragon 732G chipset as well as 33W fast charging. The Redmi lưu ý 10 Pro starts at Rs. 15,999 (~$218) for the base model.

There’s also the Poco M3 Pro with its snazzy design, Dimensity 700 processor, 5G compatibility và large battery. The phone is priced starting at Rs. 13,999 making it excellent value.

The Realme Narzo 20 Pro is yet another similarly priced alternative, that adds incredibly fast 65W charging, a 4500mAh battery, và a Helio G95 processor khổng lồ the mix.

As is usually the case, the choice of phone really comes down to what your priorities are. The Redmi note 9 Pro succeeds at delivering value. An above-average camera, class-leading internals and beautiful design for the low price of Rs. 12,999 is certainly tempting.

However, if you have an inclination towards gaming, the Poco X2with its Snapdragon 730 chipset and 120Hz display would be the better choice for you. Meanwhile, the Realme 6 takes a hit on performance but gives you a superior imaging experience. Along the way, you will also take a hit on battery life, but hey, at least you get khổng lồ enjoy that gorgeous 90Hz panel.

As an tăng cấp option, buyers should also look at the Redmi cảnh báo 10 Pro which brings several quality of life additions all around for not much more money.

In fact, I’d also urge potential buyers lớn look at the Poco M3 Pro that offers a lot more power & an excellent design with an ad-free experience and significantly faster charging.
