Choosing a smartphone in the secondary market or in the segment of budget devices often leads a potential buyer to the model Redmi Note 5. This gadget has become a real hit of its time, but due to the many modifications and regional versions, it is extremely easy to get confused in them.
In this article, we will take a look at all the nuances so you can make an informed decision, we will touch on the issues of processor performance, camera quality, and compatibility with Russian communication frequencies, and understanding these differences will help you avoid buying a device that will not work fully in our latitudes.
It's worth noting that despite the model's age, it's still in demand as a reliable workhorse or child's phone, but the architecture of the device varies dramatically across regions, and it's this factor that becomes the deciding factor when choosing a particular instance.
Key differences between regional versions
The first thing a customer faces is a few modifications, the main difference being the processor and network support. The global version, known as the Redmi Note 5 Pro in India and simply the Redmi Note 5 in Europe, is based on the Qualcomm chipset. At the same time, the Chinese counterpart, often called the Redmi Note 5 AI, may have different characteristics.
It is important to understand that Chinese versions often lack critical LTE bands. If you buy a device designed exclusively for the domestic market of China, you risk being left without 4G Internet when traveling outside the city or even in some areas of megacities.
- 🌍 Global version (Global) – fully adapted to international communication standards and has Google services out of the box.
- 🇨🇳 Chinese version (CN) — Often requires flashing, Band 20 and Russification may not be available in the menu.
- 🇮🇳 The Indian version is a hybrid, often identical to the global one, but with features of marking and configuration.
⚠️ Warning: When buying a used device, be sure to check the model in the settings "MI" at the beginning of the code (e.g, MEE7S), It is almost always a Chinese version with all the consequences.
The differences are not only in hardware, but also in software shells. Global firmware is more stable with our services, while Chinese can aggressively kill background processes, which causes notifications from messengers to come with a delay. MIUI firmware for different regions has its own optimization features.
CPU battle: Snapdragon 636 vs. competitors
The heart of the successful global version was the Qualcomm Snapdragon 636, a chipset that was a breakthrough in the budget segment, offering performance close to the flagships of the previous generation, and it is the presence of this processor that makes the smartphone relevant even a few years after its release.
Some versions, especially the early Chinese ones, have the Snapdragon 625 or 630, which are good but less powerful chips. The difference in interface speed and heavy applications between the 636 and 625 is palpable to the naked eye, so when you choose which is better, the answer is clear: look for the version on the 636th dragon.
The 14nm process provides a great balance between power consumption and heating. The smartphone rarely suffers from trotting (reduced frequency due to overheating), which is typical of cheaper counterparts. the Adreno 509 graphics accelerator allows you to run popular games on medium settings with a comfortable FPS.
💡
To test the real CPU, use the CPU-Z or AIDA64 app. Marketplace vendors sometimes indicate incorrect characteristics in the product card, trying to pass the old model as a new one.
However, it is worth remembering that even a powerful processor will not save if RAM is scarce.The minimum comfortable option today is the configuration of 4/64 GB. Versions with 3 GB of RAM will experience difficulties with multitasking in modern conditions.
Cameras: Dual module and processing algorithms
One of the main arguments in favor of this model was the camera, which has the main Sony IMX362 sensor with an aperture of f/1.9 in the global version, the same sensor that was used in the flagship Google Pixel 2, which indicates its high potential.
The second camera acts as a telephoto lens with two-fold optical zoom, allowing you to take high-quality portraits with natural background blur. AI algorithms built into MIUI Camera are great at recognizing scenes. At night, the smartphone also performs above average for its class thanks to optical stabilization (OIS).
| Characteristics | Main camera. | Secondary camera | Front camera. |
|---|---|---|---|
| Matrix | Sony IMX362 | Samsung S5K3M3 | Sony IMX376 |
| Permission | 12 MPs | 5 MP | 13 MP |
| Aperture | f/1.9 | f/2.0 | f/2.0 |
| Features | OIS, PDAF | Portrait mode | Selfie flash |
The front camera has its own flash and infrared sensor to unlock the face in the dark, which is rare in the budget segment. Video quality is limited to FullHD at 30 frames per second, which is standard, but not more.
⚠️ Note: In Chinese versions with Snapdragon processor 625 Often, completely different, weaker cameras are installed (for example, the camera is installed, 12+5 Visually, the camera block may look similar, but the quality of the photo will be significantly worse.
Software-based processing of photos depends on the firmware version. Global versions often have a more “natural” color reproduction, while Chinese versions can over-saturate colors. For enthusiasts, the Google Camera (GCam) installation is available, which unlocks the potential of Sony’s sensor to the maximum.
Screen and multimedia capabilities
The display of the smartphone is made by IPS technology with a diagonal of 5.99 inches and a resolution of FullHD +. The pixel density is 403 ppi, which provides excellent picture clarity. Color reproduction is set up quite brightly, although the brightness reserves on a sunny day can be at the limit.
The 18:9 aspect ratio allows you to comfortably hold the device with one hand, despite the large screen.Gorilla Glass protective glass (according to the manufacturer) is present, but its thickness and real resistance raise questions among users.
Technical details of the screen matrix
The soundtrack is equipped with a separate DAC, which provides clean sound in the headphones. The speaker one, located on the lower end, it is quite loud, but lacks deep bass. For multimedia, having a separate 3.5 mm jack is a huge plus, allowing you to use high-quality wired acoustics without delay.
Autonomy and charging speed
A 4,000mAh battery coupled with the energy-efficient Snapdragon 636 processor delivers great autonomy. In mixed-use mode (social media, calls, a little video), the device lives easily for a day and a half to two, one of those rare cases where the declared capacity matches reality.
Support for Quick Charge 3.0 fast charging technology allows you to recharge the battery from 0 to 50% in about 30-40 minutes. However, the package often comes with a conventional 10W charger (in older shipments) or 18W (in new ones).
- 🔋 Talk time – up to 20 hours.
- 🔋 Video playback - before 12-14 watch-watch.
- 🔋 Standby mode – minimum charge consumption due to optimization MIUI.
The battery inevitably degrades over time, and when you buy a used device, the battery's condition is a key issue, and if the capacity has dropped below 80 percent, you have to budget for the replacement cost.
☑️ Checking battery status
Communication, NFC and Navigation
This is one of the most painful issues for this model: the global version of the Redmi Note 5 (model code M1803E6GG) does not have an NFC module. This is a confirmed fact that often comes as a surprise to customers expecting contactless payment. In some regions (for example, India) there were versions with NFC, but there are very few of them.
And in terms of navigation, it depends on the version. GPS, GLONASS and Galileo – Chinese versions may have trouble mapping themselves in some navigators, although the coordinates are correct. SIM-cards implemented through a hybrid slot: either two SIMs or SIM + memory-card.
⚠️ Please do not believe the sellers who say that NFC You can program it on a global version, the antennas and the chip are not physically on the board, and the only way is by making complex hardware modifications that nobody does en masse.
