Redmi 9 Review

The presence of Redmi 9 in mid-July cannot be underestimated. This smartphone made by Xiaomi has great potential to dominate the entry level market. Having an attractive appearance with adequate specification support further adds to the peak position that is easily achieved. Moreover, Redmi’s branding so far is already quite good in the market. This time my team had the opportunity to try out the global version of Redmi 9. Understandably, this unit was sent before the official version launch date in Indonesia. And indeed there is no difference between the global market version and for the homeland. So the process of reviewing products is also easy to do. Then is it true that our hypothesis that Redmi 9 will rule the market in its class? No need to elaborate anymore, please refer to our following review.

Redmi 9 Specifications and Review

Redmi 9 is made with a choice of textured designs on the back cover. Like crop circles, the texture of the line is circular around the smartphone camera. So that it brings out an elegant and balanced feel to the design. An impression that was indeed tried to be manifested by Redmi 9. The circle of camera lenses is neatly aligned vertically. Uniquely among the rows there is one of the lowest circles which is a fingerprint sensor. Its location in the array of camera lenses, had made us think that this smartphone uses a side-unlock fingerprint. Redmi calls this design an “anti-fingerprint texture back”.

Unfortunately, the location of the finger scanner feels uncomfortable to us, because the model that sticks out follows the height of the lens. One more thing that is unfortunate is the existence of a line of bokeh and flash camera lenses on the side of the main series, a bit of a disperse impression of balance there. For the color choices in Redmi 9, there is no longer a violet color gradation like some other products. The colors used tend to be solid with three choices namely carbon gray, ocean green, and sunset purple. Similar to its predecessor Redmi 8 which did use a similar solid color choice.

At the front, Redmi 9 still utilizes the concept of water drop or notch, for the camera lens. A somewhat outdated model, yes. Given that many manufacturers are now starting to switch to punch hole models, without pulling the line from the side of the smartphone to place the camera. The rest of the placement of the function key and port feels still normal. The same is found on many smartphones in the same price range. The difference may be at the point where the infrared, which has been the hallmark of Xiaomi / Redmi phones long ago, at the top of the cellphone. Adjacent to the noise cancellation hole.

Looking at the smartphone design with dimensions of 163.32 × 77.01 × 9.1 millimeter and weighing 198 grams, it feels more than enough for an entry-level smartphone. Four rear cameras are placed in such a way, with an attractive cover concept approach, so that users do not feel bored with the generic design sequence. We just thought, why do you make a cover with a circular texture like this, if you later use additional silicon. Right?

Redmi 9 Review


Redmi 9 has a screen area of ​​6.53 inches. Made using Full HD+ technology, the dot drop display as the location of the camera lens. At a 19.5: 9 ratio level, Redmi 9’s visuals can present resolutions up to 2340 x 1080. And have a brightness level of up to 400 nits, and a 1500: 1 contrast ratio. With such a high level of brightness, users might wonder whether it can affect the function of vision. Especially when using a cellphone for a long time. Yes and no, because this is influenced by many factors.

But right, smartphones are now able to optimize the level of contrast with lighting conditions in the room. Plus, Redmi 9 has already won certification for low blue light from TÜV Rheinland. Competent in the field of inspection various electronic and automotive technology products. One more thing, despite the design of the dot drop, water drop, notch, or whatever it’s called, on this smartphone. But thanks to the large size of the screen finally makes the activity of exploring the menu, watching movies, to playing games can still be enjoyed as it should. Yes, at least that’s how we feel.


The temptation of four cameras in the back and one camera in front of the Redmi 9 is definitely very soul-moving. It only makes many people feel tempted. Moreover, each camera lens has different functions ranging from ultra-wide, depth sensors, and macros that are currently infatuated in many products lately. Redmi 9 places four rear cameras in the center of the cover. With each capability, namely the main camera with 13MP wide-angle camera specifications – f / 2.2, AF, 1 / 3.06 ’’ sensor, 1.12μm pixel size – 5P lens, f / 2.2, 75.2 ° FOV. This camera is clearly the foremost choice when it comes to producing the best photos. Plus HDR features, AI, and filters that are used together when trying to take pictures. So there is no need to enter the editor menu again. Live photos can be enjoyed.

Problem setting the camera menu, we can find more in the settings. Like the existence of the tilt-shift feature for better focus, straighten so that the object’s position is right in a straight line. And setting the timer, google lens, frame size, and gridlines on the camera screen visualization. Making use of the Redmi 9 camera feels very user friendly, and fun. There are still three other camera lenses. First, the 8 MP ultra-wide camera 118 ° FOV, 1/4 ‘sensor, 1.12μm pixel size – 5P lens, f / 2.2. This wide angle of the lens makes focus on the object pursed to the center of the lens. While the line of objects on the edge looks drawn away. Because that’s the concept of an ultra-wide lens. At this level of resolution, outdoor photos can be maximized compared to the opposite concept.

As for the two other lenses, namely 5MP macro camera – 1/5 ” sensor, 1.12μm pixel size – 3P lens, FF (4cm), f / 2.4, and 2MP depth sensor – 1/5 ” sensor, 1.75μm pixel size – 3P lens, f / 2.4. Macro mode has become a new feature to fill the need for close-up photography. For those who use their smartphone to photograph merchandise, this kind of camera can be an awesome weapon to represent the product. Showing a deeper and perfect detailed line draw. And the good macro camera in Redmi 9 is able to produce it well. The last lens for bokeh needs feels like a lot of reviews and that’s it. The 2 MP resolution quality is indeed able to present adequate bokeh quality. Even in low light situations. And by adding other elements to manual editing, the style and quality of photography can be significantly improved.

Then what about the front camera concept of Redmi 9? 8MP quality selfie camera – 1/4 ” sensor, 1.12μm pixel size – 4P lens, f / 2.0 with a variety of interesting features presented here. Features such as palm shutter, cinematic portrait, screen flash, and portrait mode are additions that should not be missed. Redmi also puts frames in landscape mode for more dramatic photos. Including the existence of filters that are directly visible on the screen as a preview. The ability of the three main lenses behind the smartphone also applies to video functions. With a choice of resolution options in numbers 1080 full HD or 720 HD. Where users can choose one of the wide, ultra-wide lenses and macros before recording. When recording, users can zoom in / out for more dramatic images.

An interesting feature of the Redmi 9 video function is the presence of a kaleidoscope, and speed. The speed feature, as we already know, provides the opportunity to record at high or low speed (slow motion). Of course with the help of adequate light so that the maximum recording results. Meanwhile the kaleidoscope feature produces more complicated videos by breaking the focus of the lens. Both are only in short video mode. And it’s more intended for users who like to share videos on other platforms such as tiktok and Instastory.

We can say that all the functions and features of the Redmi 9 camera are so tempting to visualize all imagination and creations. Each feature feels so right and not excessive to use. It’s just that there is no default application for processing photo and video creations on Redmi 9. Making the whole process of photos and videography not reach its climax.

Other Features

Redmi 9 uses the MIUI 11 interface based on Android 10. We think its performance is more than enough. Switching between menus that flow smoothly. Available turbo / booster game for maximum playing experience. Dark mode, which is starting to be liked a lot. Until the availability of Mi Account, for ease of storage and integration with other products from Xiaomi. Such interesting features are still a mainstay of the user interface on each Xiaomi smartphone.

The security sector Redmi 9 supports the ability to read faces very well. Although this kind of face reader feature is rarely used. But it still becomes necessary especially when users have important data to be protected in such a way. Complete the existence of a fingerprint scanner, and other lock options. And there is a feature called “pocket mode”, which can be activated. Works when the smartphone is stored in the user’s pocket / trousers. With this feature active, the Redmi 9 screen is not sensitive to unnecessary touch movements, which can sometimes activate a smartphone without us knowing it.

Redmi 9 performance review

Redmi 9 utilizes Mediatek Helio G80, 12nm process technology, octa-core CPU, up to 2.0GHz, as a working brain for smartphones. Redmi revealed that the selection of the processor is to be able to optimize battery usage longer, better gaming performance, and good facial recognition in smartphone security features. And that’s what we got when we tested Redmi 9. This cellphone able to play a game such as Player Unknown mobility, Battleground, or beautiful visual hunters in Asphalt 9, a moment is gone. Yes, Redmi 9 is able to handle these popular games well. Both in the smooth gameplay and visual design that is presented.

But, there is a cover, of course there is a decrease in the quality of graphics there. The ability of Mali-G52 MC2 950 Mhz still cannot accommodate the resolution requirements of these heavy games. There are left lines or details that are missing. If that is not your main concern, then it can be ignored. Because the game itself can still be enjoyed properly. Apart from the processor capabilities on the Redmi 9. Actually, this smartphone also offers other advantages through large memory capacity in its class. There are two different choices of internal RAM and storage, namely 3GB + 32GB and 4GB + 64GB. Add additional options through the microSD memory slot up to 512 GB.

On the Redmi 9 power requirements obtained from batteries with a capacity of 5020 mAh. The battery supports the Quick Charge 3.0 feature, OTG charging, and is able to accept charging up to 18 watts. So called, because in the purchase package, Redmi 9 is only given a 10 watt charger head only. Not bad, just not fast enough. Overall, we cannot ask for better than what Redmi 9. has to offer. What is obtained from Redmi 9 already feels very encouraging.


One of the main competitors for Redmi 9 comes from the C11 Realme. With a lower price, the C11 Realme is like providing other options for those who lack funds. But if you look deeper, Redmi 9 clearly has advantages far from the price margins of the two mobile phones. So the detailed specifications and features on the Redmi 9 clearly become undeniable advantages. Design and processor can be ignored, if you see a camera sector that is qualified and in fact often also be a concern when you want to buy a smartphone. So we highly recommend Redmi 9 to enter the purchase list in the entry-level class, or you who really do not want to work just for a smart communication tool.
