Redmi Note 9 Pro: complete phone specifications

The increasing need for smartphones with good technology has announced Redmi Note 9 Pro (one of the Redmi Note series) as a good option. Recently, the popularity of Xiaomi can be linked to Redmi smartphones especially the Redmi Note series. This category of smartphone has really gained the trust of smartphone lovers because of their peculiarities.

Xiaomi is one smartphone brand that actually gives quality for an affordable price. The company has sold over 10 million units of Redmi Note 4, and last year, Redmi Note 7 Pro bagged the highest-selling phone award. However, that doesn’t keep them away from strong competitors in the smartphone world. Realme is its toughest competitor so far, their smartphone almost matches Xiaomi’s spec most times. Hence, the need for continuous improvements.

If you want to get a portable smartphone, then Redmi should be your choice. We will briefly review that phone and unveil its full specs, so you will have an idea of what you want to buy.

This is mostly the deal-breaker for some smartphones. And this is likely the first thing that will draw attention to the phone. The Redmi Note 9 Pro comes with a glossy pane of Gorilla Glass at the back of the phone. The Aurora Blue colour can do the work of a mirror at the right angle. It has a case, which is convenient if you don’t want to clean up smudges regularly.

However, there are repetitions on similar design patterns. Just like its sister Redmi Note 8 Pro, you can see the camera at the center of the phone (at the back). No vertical arrangement. There is an enclosure of all four sensors in a rectangular action with the flash below it.

You will also find the fingerprint sensor at the side of the phone, which makes unblocking the phone quite easy. It has an integration with the power button. You can easily reach the button even with one hand. Also, the volume rocker is not segmented. Because of its position, it I quite difficult to locate without making use of your two hands.

There is also a USB-C port at the bottom edge as a headphone jack. At the left, you will find the joint slot for dual nano-SIM cards and a microSD card for storage expansion. But it still retains an IR blaser at the top.
It comes with a 6.67-inch display, 20:9 taller aspect ratio and a Full HD+. Panel is 120Hz plus a camera cutout for the front camera.

In all, Redmi Note 9 Pro is a conservative, but its aesthetics is something to hold on to. However, the weight of Redmi Note 9 Pro is quite ridiculous, weighing 209g. This may not be an issue to you, but it holding it for long durations can become an issue. It is not waterproof but it retains a P2i coating with offers an amount of splash resistance.


While the Redmi Note 8 Pro uses a Mediatek Helio G90T, the Redmi Note 9 Pro comes as a Snapdragon 720G. This chipset is a combination of two Kryo 465 Gold cores, as well as six Kryo 465 Silver cores. Daily performance is satisfactory as MIUI supports the hardware and gives off a sleek experience. There is not stutter or iota of lag.

However, RAM may not be an issue depending on your choice. The chipset (Snapdragon 720G can pull through any game or app you throw at it). But we advise gamers to keep off the base section of the phone with just 4GB of RAM. It is also not a great choice for longevity purposes. PUBG works without stutters.


The battery is also one of the first things every smartphone user gets to consider before buying a phone. The Redmi Note 9 Pro changed the normal trend of 4,000mAh for Xiaomi phones. It comes with a cell of 5,020mAh that can last your for a long day of heavy consumption. Charging speeds are limited to 18W and it takes about 140 minutes to top up from scratch.


One reason Xiaomi still keeps hardware prices low is that it includes software services and ads in the operating system. MIUI functions properly. It can tweak features, add themes, set lock-screen wallpaper, and also serves as a file manager.
However, the tossing in of third-party apps remains out-of-place. You can go to the settings and disable these apps.

Redmi Note 9 Pro also comes with standard features like style performance, and stability enhancements. Earlier this year, Xiaomi gave out a new MIUI update with the May Android security patch and no extra features.
Luckily for Xiaomi, the company is set to roll out security patches.


There is still a specific camera set-up amongst the Redmi Note 8 Pro and the new Redmi Note 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, however, is a 48MP Samsung GM2 sensor. This is contradicting to 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.

Also, the cameras on the Redmi Note 9 Pro are quite manageable if you compare it to other middle-range smartphones. The good thing is that Xiaomi has opts for very natural-looking color science here. More often than not, the color temperature and white balance are spot-on which is very easy to see. The dynamic range isn’t too awful either with some. But not the shadow doesn’t retain all details. However, there is a certain softness to images when you capture them with the Redmi Note 9 Pro. But surface-level detail is missing in a lot of images.

On that note, despite pixel-reducing images down to 12MP, there is a lot of grain and noticeable noise when pixel-peeping, irrespective of the lighting conditions. In some cases, it isn’t really an issue, but it becomes readily obvious when cropping into the frame.

If you like shooting ultra-wide images, or in portrait mode, the Redmi Note 9 Pro does a good job in that aspect. Dynamic range is a bit limited when shooting with the wide-angle sensor and white balance can be slightly off.

However, the mode works well to capture a wide frame without much effort. Meanwhile, Xiaomi has done a particularly good job in the optimization of the portrait mode. Also, Redmi Note 9 Pro performs a great job at edge-detection, and creating a natural-looking blur.

It also comes with a 5-megapixel macro camera tossed into the mix, and it does a perfect job. If you are not a big fan of a dedicated macro lens and would rather have a telephoto shooter instead, then you can go for a better choice. Still, if you want to get up close and personal with your subjects, you have the option.

Night Mode
Night mode is, however, when the Redmi Note 9 Pro really acts clumsily. With the primary camera, images turn out to be horribly grainy with digital artifacts and irregular-shaped stains. This creates a nearly unusable shot. Things improve by a small degree when you use the night mode option. Still, the image is far from beautiful. This gives its competitor Realme, with Realme’s hardware, you are at advantage because it outweighs the Redmi Note 9 Pro in this regard. Asides that, the camera does a reasonable job of capturing selfies from the 16MP front-facing camera..

The video is not excluded in Xiaomi improvement over the years. It has made changes to the video mode as well. The camera captures crisp footage all the way up to 4K, 30FPS. Though the exposure levels are consistently just a bit too high. The software additions now appeals to content creators, and includes a cinematic 21:9 crop mode as well as built-in filters. In a cool-to-have feature, the video camera allows you to shoot straight-from-the-sensor log video footage, which makes it much easy to color grade in software like Premiere Pro or Resolve.


As is the case with mid-range hardware, a headphone jack is part of the package. Audio output from the Redmi Note 9 Pro sounds good enough without any noticeable issue. If you plug in a pair of 1More Triple Driver earphones, the audio output goes loud enough and offers a reasonable amount of dynamic range. Not the best resolving output, but it will suffice in a pinch if you just want to listen to some tunes on the go. Speaker output is loud but lacking in bass. Dual stereo speakers would have definitely improved the experience.

If you intend to use Bluetooth headphones with the Redmi Note 9 Pro, the phone can output over AptX, AptxHD, and LDAC. So there is a guarantee that you will get high-quality audio as long as your headphones support the necessary codec.
