In the world of budget smartphones, few devices that could leave the same bright mark as the Xiaomi Redmi Note 9 Pro. This model became a real phenomenon, setting the bar for performance and equipment for the mid-range, which competitors have been striving for a long time.
Now, a few years after its premiere, the question of whether to buy this gadget sounds different: the market is saturated with new models, technology has stepped forward, and the prices of used devices and inventory balances make it more affordable than ever.
In this article, we will conduct a deep analysis of the technical characteristics, analyze the real-world experience and find out who this smartphone will be perfect and who is better to pass by.
Body design and ergonomics
The look of the smartphone makes it clear that you're not seeing an entry-level device, the back is made of matte plastic, which is nice to touch and, more importantly, almost does not collect fingerprints. The camera block, which is placed in the upper left corner, occupies a significant area and has a characteristic circular shape, resembling a window of a spacecraft.
The size of the device is not compact. The screen size of 6.67 inches dictates its conditions: one-handed control is only possible for people with a large palm. Weight of 209 grams is tangible, especially with prolonged use. However, the assembly is done well, the backlashes and creaks in the case are not observed even in second-hand copies.
Special attention should be paid to the availability of full-fledged IP53 water protection. This does not mean that the phone can be immersed in water, but it will easily survive accidental splashes or use in the rain. For the budget segment, this is a rarity, which often becomes a decisive factor in choosing.
⚠️ Note: Despite the presence of markings IP53, Do not try to test waterproof under a stream of water or by dipping the device into a liquid.
The arrangement of the controls is classic for the brand's products, the fingerprint scanner is built into the on button on the right side, it works quickly and accurately, unlocking the device in a split second. SIM-The card and memory card are located at the bottom, next to the connector USB Type-C and 3.5mm headphone jack.
Display: characteristics and image quality
The screen is one of the main reasons why the model is so popular. IPS-resolution-matrix 2400 × 1080 The pixel density is high, so you don't see the graininess even if you look closely, and the color reproduction is fine-tuned, although there's a slight cool-tone retreat by default that you can adjust in the settings.
The brightness of 450 nits is enough for comfortable use indoors and in cloudy weather. However, in direct sunlight, reading text can be a bit difficult — the brightness margin is not the highest. Viewing angles are excellent, the image does not invert or fade when viewed from the side.
An important feature is the presence of protective glass Gorilla Glass 5. This provides good protection against scratches when carried in a pocket with keys. However, glue protective film or glass is still recommended, as impact strength when falling on asphalt is not guaranteed.
The screen refresh rate is the standard 60Hz. In 2026, it no longer looks impressive against competitors with 90 or 120Hz. Scrolling the feed on social networks will not be perfectly smooth, but after a conventional 60Hz monitor, the difference is not noticeable.
Productivity and gaming opportunities
At the heart of the smartphone is the Qualcomm Snapdragon 720G processor. At the time of its release, it was the king of the mid-segment, and even today it is capable of much. The eight-core architecture and 8nm process technology provide excellent energy efficiency and sufficient power for most tasks.
In everyday tasks — instant messengers, a browser with a dozen tabs, navigation, YouTube — the device works confidently. the interface MIUI (or HyperOS depending on the firmware version) can slow down when you open heavy applications, but in general the system responds quickly, the input delay is minimal, which makes using the phone enjoyable.
As for games, the situation is ambiguous: lightweight projects like Clash Royale or Among Us fly at maximum settings. However, today's heavy games require compromises. PUBG Mobile or Call of Duty will have to reduce the graphics to a minimum or average level to get playable 30-40 frames per second.
⚠️ Attention: During long-term heavy play 3D-Shooter smartphone body significantly heats up. This can lead to a decrease in the brightness of the screen and trottling (reduced processor frequency).
RAM volume varies depending on the version: 4 or 6 GB. For 2026, 4 GB is the absolute minimum at which applications can often be unloaded from memory. The 6 GB version is preferable, it allows you to keep more running programs in the background.
Results in AnTuTu
Cameras: photo opportunities and video shooting
The main camera module has a Samsung GW1 sensor with a resolution of 64 MP. It is a legendary sensor that is still used in many models. During the day it takes great pictures with high detail and good dynamic range. Photo processing algorithms from Xiaomi do well with color reproduction, making the shots bright and juicy.
Night photography is possible, but it's not a miracle. There's no special night mode in the classical sense, although algorithms try to pull the frame through long exposure. There's a lot of noise in low light, the detail drops. An 8MP ultra-wide angle camera is more for variety — quality acceptable only in good light.
Video is being shot at up to 4K at 30 frames per second. Electronic stabilization, it works well, but the jerks are still noticeable. The sound is recorded monophonic, which is the standard for this price segment, but in 2026 you want to see at least basic stereo recording.
| Camera module | Permission | Aperture | Features |
|---|---|---|---|
| Basic | 64 MP | f/1.89 | Phase autofocus, 4K video |
| Ultrashire | 8 MP | f/2.2 | Viewing angle 118° |
| Macro | 5 MP | f/2.4 | Focal distance 2-10 cm |
| Depth sensor | 2 MP | f/2.4 | For portrait mode |
The 16MP front camera is inscribed in the screen notch. It takes good selfies for social media, but makes a lot of noise in bad light. The background blur feature is software-intensive and sometimes miscontour hair.
Autonomy and charging speed
One of the big trump cards is the 5020 mAh battery, which is a huge amount of energy that allows you to confidently achieve two days of operation with moderate use, even active users can reach a full day with a margin of 20-30% by the evening.
Complete charging supports 30 watts. It's not a record 120 watts like flagships, but not a slow 10 watts. Full charge from zero to 100% takes about 1 hour 15 minutes. For a capacity of 5000 mAh is a great result, allowing you to quickly replenish energy in the morning before going out.
☑️ How to extend the life of the battery
It's important to note that there's no battery charge back. You can't charge your headphones or your phone's watch. You also have to consider that over time, the battery capacity naturally degrades, and the actual capacity of the used ones may be lower than the declared capacity.
💡
The combination of powerful battery and fast charging of 30 watts makes the Redmi Note 9 Pro one of the leaders in battery life in its class even today.
Software and relevance
The smartphone originally launched on Android 10. It has received updates to Android 11 and Android 12. At the moment, official support for major Android updates has been discontinued, the device receives only rare security patches. However, this does not mean that the phone has become useless.
The MIUI 12.5 shell or MIUI 13 shell (depending on the region) is stable, and the functionality is huge: customization, gesture control, app cloning, second space, all of these things work smoothly even on this hardware.
For enthusiasts, the Redmi Note 9 Pro (codename curtana) remains one of the most popular models for custom firmware installation. The developer community is actively supporting the device by offering current versions of Android 13 and 14 through LineageOS or Pixel Experience.
⚠️ Warning: Install custom firmware (root rights, unlock the bootloader) will cancel the warranty and may lead to the inoperability of banking applications (Google Pay / Mir Pay will cease to work without additional manipulations).
