The importance of the note series of phones in Redmi’s lineup cannot be overstated. It is the phone that put the company on the bản đồ and helped xiaomi mi gain massive global momentum. The Redmi note 4 sold over 10 million units over its sản phẩm cycle, & last year, the Redmi chú ý 7 Pro was India’s highest-selling phone in the Rs. 10,000 và above category. Suffice it khổng lồ say, it is critical for the brand khổng lồ 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 and sometimes beat it.

With that in mind, it is all the more important for Xiaomi lớn build a sản phẩm that doesn’t just meet a checklist but pushes forward. Is the Redmi chú ý 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A newer version of this device is now available.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 cảnh báo 10 ups the ante in nearly every way including performance, a significantly upgraded design, and a much-improved 120Hz AMOLED display. Read our Redmi note 10 Pro reviews for full details.
About this review: I wrote this Redmi cảnh báo 9 Pro reviews after spending a week with the phone as my primary device. Mi India supplied the device, which was running game android 10 with MIUI 11 on board.

Update, Aug 2021: The review was updated khổng lồ reflect fresh software updates, competition, and value for money.


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

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


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

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


Like the Redmi cảnh báo 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 key và I found it khổng lồ be extremely fast at unlocking the phone. The button is intuitively placed & very easy khổng lồ 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 headphone jack. Over on the left is a combined slot for dual nano-SIM cards as well as a microSD thẻ 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 to lớn stablemate the Poco X2 and 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 lưu ý 9 Pro on the back foot compared khổng lồ its peers.

Overall, the Redmi cảnh báo 9 Pro is a conservative, but pleasant step forward as far as aesthetics are concerned. I bởi vì have an issue with the sheer weight of the phone though. Clocking in at 209g, the note 9 Pro can get cumbersome to 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 note 9 Pro sees the company returning khổng lồ Qualcomm’s Snapdragon platform. While the chú ý 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.

Performance is not an issue, but I'd steer clear of the 4GB RAM variant of the Redmi lưu ý 9 Pro.

Depending on the variant you opt for, RAM may or may not be an issue. I’d advise gamers to 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 khổng lồ hold on to 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 thử nghiệm out PUBG with the graphics turned up to maximum without any noticeable stutters.

Big battery, slow charging

Xiaomi pioneered the trend of slapping large 4,000mAh batteries in phones, & the lưu ý 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 chú ý 9 Pro takes time.

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

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

At its best, MIUI integrates a world of functionality và tweaks right out of the box. From being able khổng lồ tweak gestures, add themes, set rotating lock-screen wallpapers, lớn including a competent tệp tin manager and software khổng lồ quickly giới thiệu 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 tiện ích inclusions seems to be increasing with every successive release và not all of these can be removed. địa chỉ cửa hàng to that notification bar spam và 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 and March. The updates also bring in standard features like system performance, stability enhancements.

In May 2020, xiaomi issued out a new MIUI update with the May android security patch & 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 app android 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 to lớn the Redmi cảnh báo 9 Pro, & 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 vi xử lý core camera set-up remains consistent between the Redmi cảnh báo 8 Pro and the all-new Redmi cảnh báo 9 Pro. The quad-camera cài đặt 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 note 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 web8_news is that xiaomi has opted for very natural-looking màu sắc science here. More often than not, the color temperature and white balance are spot-on which is very good to 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 lớn images captured with the note 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 to lớn 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 lượt thích shooting ultra-wide images, or in portrait mode, the Redmi note 9 Pro does a good enough job. Dynamic range is a bit limited when shooting with the wide-angle sensor & white balance can be ever-so-slightly off. However, the mode works well to capture a wide frame without much effort. Meanwhile, mi has done a particularly good job at optimizing the portrait mode & 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 hâm mộ of a dedicated macro lens và would rather have a telephoto shooter instead. Still, if you want to get up close & personal with your subjects, you have the option.

Night mode is, however, where the Redmi lưu 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 và competitor Realme’s hardware blows away the chú ý 9 Pro in this regard. Elsewhere, the camera does a reasonable job of capturing selfies from the 16MP front-facing camera. Hit the links to see some high-resolution Redmi note 9 Pro camera samples.

Xiaomi has made improvements lớn the đoạn phim 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 lớn appeal to content creators, & 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 đầu ra from the Redmi chú ý 9 Pro sounds good enough without any noticeable hiss. I plugged in a pair of 1More Triple Driver earphones and 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 lớn some tunes on the go. Speaker output 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, and LDAC so you are guaranteed to get high-quality audio as long as your headphones support the necessary codec.
