The history of one of the best manufacturers

Redmi is a sub-brand that was once part of one of the giants of the Celestial Empire Xiaomi, but since the beginning of 2019 has set off on an independent voyage. It is positioned by the release of low-cost smartphones that belong to the lower and middle price segment. The first brainchild is considered to be the 2013 device called Xiaomi RED Rice. In recent years, many concerns have decided to release separate lines of devices of their own production. At Oppo, it became a sub-brand of Realmi, Huawei introduced the world to Honor.

Xiaomi Redmi 9 Prime

Overview of the appearance of the device

The 6.53-inch capacitive display has a resolution of 2340x1080 pixels. The 400 nits backlight is enough for comfortable reading of your favorite literature, active games on the network or surfing the Internet.The glass is protected, but the class is not enough to not think about buying a cover. It is recommended to give preference to transparent structures, since the color of the plastic elements of the smartphone looks amazing. The factory film is of high quality, however, experts advise sticking a protective screen on the display.

The color scheme settings are standard, however manual intervention is allowed in the form of setting the dark theme and color depth. The maximum backlight is sufficient to read information from the display.

The pixel density is 395 ppi. The main material is protected glass and plastic. The colors are rich and unusual. Many people liked the choice of colors. There are four body colors: space blue, mint green, matte black and a flash of the rising sun. The translation is literal, but the colors really turned out to be unusual and beautiful. The build is not bad. No creaks or backlashes were found. The speed of the sensor (blocking) response leaves much to be desired, but you can't count on otherwise, because the phone belongs to the category of inexpensive.

During use, many small scratches appear, so you should think about the cover in advance. The drawing shimmers in the sun, so you should expect a huge amount of compliments and interest. The front camera is made in the form of a droplet, which cannot be called something unusual. At the back are four cameras, a fingerprint sensor and a flash. The SIM card slot is located on the left side panel. To open, you need a special key that is included in the kit. The power button and volume control are located on the right side panel.

Screen and additional features

The declared characteristics of the Xiaomi Redmi 9 Prime display do not differ much from its predecessor - Xiaomi Redmi 9. The diagonal has become a little larger, 6.53 inches, a standard matrix with Full HD + resolution, there is support for HDR and an aspect ratio of 19.5: 9. The brightness reserve deserves special attention, which will allow reading information from the display even in bright sun. For viewing content, the diagonal is convenient, based on numerous reviews on the network. Fingerprints remain, but can be easily removed with a cloth. After the purchase, it will not be superfluous to remove the function of automatic calibration of colors, which are too saturated here.

Among the functionality, it should be noted the presence of the ability to enable double-click wake-up, activation of a hidden cut-out and a dark theme. You can also turn on the display of basic information on the off lock screen.

DC Dimming is responsible for reducing the flicker factor, which has been carried over from the previous generation model. This option is extremely useful especially for those who like to sit in chats for a long time and read from the phone. The display turned out to be of high quality and very convenient for games. However, it should be noted that the currently popular model has slightly curved edges of the display, so when exposed to direct sunlight, using the gadget in the sun becomes less comfortable. Special anti-glare films or glasses can come to the rescue.

It will be difficult to avoid false clicks, since the branded cover hardly hides the side edges. It should also be noted that in the process of creating test photos or recording video, accidental pressing will cause the sensor to move or pop up the menu. If the person is impatient and too irritable, then this point should be considered before buying. Examples can be seen in the photo below. The device turned out to be reliable and nimble enough for a teenager to use it. Models predict popularity not only in the Middle Kingdom, but also in Europe.


Before choosing such a device, you should pay attention to such a selection criterion as performance. The Mediatek Helio G80 processor (12 nm) is equipped with eight cores: Octa-core (2 × 2.0 GHz Cortex-A75 & 6 × 1.8 GHz Cortex-A55. A clock frequency of 2 GHz will allow the device to be used for active games.) Mali-G52 MC2.This allows you to fully enjoy the Full-HD graphics expansion with refresh rates up to 60 Hz.

It should be noted that it is more profitable to buy a device on AliExpress, where you can also see the covers for the new product.

MIUI 11, which runs on Android 10, is also responsible for the usability of the phone. Two models will enter the market: with 4 GB of RAM and 64 GB of its own memory and the more popular model with 128 GB and 4 GB of RAM. Based on the requests of the average user, it is better to buy the second option, which will have more memory. The processor is powerful enough to work with Bluetooth-5.0 and Wi-Fi 802.11-ac wireless technologies. This indicator is also sufficient for the comfortable use of navigation applications such as GPS, GLONASS, Beidou, Galileo.

It is understood that with the Mediatek Helio G80, the manufacturer can install cameras with a resolution of up to 48 million pixels. The processor also allows you to successfully work with dual cameras of 16 million pixels. In the development process, 12 nanometer standards are applied, as well as FinFen technology. The result is a high-quality device, which in the near future may lead the ratings of high-quality budget novelties for 2020. For the price, the unit is also pleasant, which sets it apart from its competitors.


How does Xiaomi Redmi 9 Prime take pictures? Just like many other budget phones. Selfies will be good. The rear cameras perform excellently for their stated performance, so the shots come out rich. How does the phone take pictures at night? Sample photo:

We can come to the conclusion that the four installed cameras cope with the designated tasks tolerably. The user can easily capture the important moments of his life, take a high-quality photo of the documents needed at work. You shouldn't expect anything else from the middle price segment. In addition, newfangled filters and applications can always come to the rescue, which will help not only to retouch the photo, but also to make the picture brighter, juicy and realistic. Selfie example:

It should be noted that the manufacturer has installed a quad camera with sensors: 13 + 8 + 5 + 2 MP. This made it possible to include a variety of auxiliary modes and functions in the device. The 8 MP front camera is located on the front panel in a teardrop notch.

The device copes with the assigned tasks perfectly. There are several shooting modes, as in the popular older generation models. The video quality is average, so if you plan to shoot videos for a long time, then it is better to give preference to another device. Stabilization is present, however, very mediocre.


The device is powered by a non-removable Li-Po 5020 mAh battery. Based on the statistics, this volume should be enough for 2 days of work or 6 hours of active games on the network. Comes with a 10W charging adapter. There is a fast charging function. If you are planning to buy a branded 18 W charger, then it is better to give preference to a branded device. The average price for such a purchase is $ 50. However, based on the declared characteristics, gamblers are unlikely to be interested in such a device. A lot of photos, calls from work and a few hours of social networks - this is the limit for such a device.


Xiaomi Redmi 9 Prime received a capacious battery, the processor is comparable to the middle price segment, a good quad camera and an infrared port, which almost no one uses anymore. The main features of this line have been observed. The headphone jack is familiar, which will allow you to listen to music on your favorite headphones, and not through an ordinary speaker, which does not belong to the category of music.
