Why itโs important to know the processor model in your Redmi Note 7
Xiaomi Redmi Note 7 is one of the companyโs most popular budget phones, released in 2019, but not everyone knows that this model came with two different processors: the Qualcomm Snapdragon 660 and Snapdragon 636. The difference between them affects performance, game support and even the ability to install custom firmware.
Knowing the exact chipset model will help you:
- ๐ Choose the right firmware or modified software (some builds are optimized only for Snapdragon 660).
- ๐ฎ Evaluate compatibility with games (e.g. Genshin Impact or Call of Duty Mobile may work better on the game). SDM660).
- ๐ง Accurately diagnose problems with overheating or slowing (chipsets have different power consumption).
- ๐ฐ Reasonably estimate the cost of the phone when selling (models with Snapdragon) 660 usually 10-15%).
In this article, we will discuss 5 proven ways to identify a processor on a Redmi Note 7 โ from standard settings to technical utilities, and learn how to distinguish a fake and why some methods can give inaccurate results.
Method 1: Checking through phone settings (the fastest method)
The easiest way is to use the built-in MIUI tools, which require no additional applications and works even without an internet connection.
Instructions:
- Open the Settings menu (the gear icon on the main screen).
- Go to the About Phone section (usually at the bottom of the list).
- Tap a few times on the MIUI version until the caption โYouโre a developer!โ appears (this unlocks hidden settings).
- Return to the main Settings menu and select a new section โ For developers.
- Scroll down to the Equipment block - there will be a Processor string indicating the model.
Enable the developer mode (stamp on "Versions" MIUI" 7 times)|Update MIUI last-minute|Restart the phone and try again|Try an alternative method (see below)-->
Important! In some versions of MIUI (especially on older firmware), the CPU name may appear as code, such as msm8976 (this is Snapdragon 636) or sdm660 (respectively, Snapdragon 660).
โ ๏ธ Note: If the processor is listed as unknown or data is missing in the For Developers section, this may mean that the phone has an unofficial firmware installed or it has been overflashed with violations.
Method 2: Use USSD code (works without the internet)
Few people know, but Xiaomi has hidden engineering codes that allow you to get technical information about the hardware.
Follow the following steps:
- Open the Phone application (keyboard dialing).
- Enter the combination: ##4636##
- In the menu that appears, select Phone Information.
- Scroll down to the Hardware Information block โ there will be a Processor or Hardware string.
If the code doesnโt work, try an alternative:
##225##It will display a list of components where the model will be specified in the CPU bar.

If nothing happens after you enter the code, check if your carrier is blocking it. SIM-map or plane.
Do not enter random engineering codes, some of which can reset or damage the system. Use only the proven combinations given in this article.
Method 3: Diagnostic applications (CPU-Z, AIDA64, DevCheck)
If standard methods fail, specialized utilities will come to the rescue, not only showing the model of the processor, but also providing detailed information about each core, frequency, architecture and even temperature.
Top.-3 apps for Redmi Note 7:
- ๐ CPU-Z โ The most popular iron analysis app, which shows the chipset model, the number of cores, the process, and even the name of the motherboard.
- ๐ง AIDA64 โ Professional tool with advanced processor data, including instruction support (ARMv8, NEON) and cache.
- ๐ ๏ธ DevCheck is a handy data visualization app. CPU, but GPU, memory and storage.
How to use (in the example of CPU-Z):
- Download the app from Google Play (or from the official website if you donโt have Google services).
- Open it and go to the SoC (System on Chip) tab.
- The Model or Hardware bar will specify the exact processor model.
| Annex | Pluses | Cons | Reference |
|---|---|---|---|
| CPU-Z | Free, no advertising, the most accurate data | Interface in English, no history of checks | Download |
| AIDA64 | Details of each component, performance tests | Paid version for advanced functions | Download |
| DevCheck | Utility interface, shows the temperature of the CPU in real time | Advertising in the free version | Download |
โ ๏ธ Note: If the application shows the MediaTek Helio processor P60 Or another chipset that doesn't meet the official Redmi Note 7 specs, your phone could be a fake. Xiaomi's original models are powered only by Qualcomm Snapdragon processors.
Method 4: Serial number and IMEI check
Each Xiaomi smartphone has unique identifiers, such as IMEI and serial number, which can be used to determine the configuration of the hardware, which is useful if the phone is not turning on or you want to check the data before you buy it.
How to find IMEI:
- ๐ฑ Dial in the phone keyboard: *#06#
- ๐ Look at the sticker under the battery (if the phone is collapsible).
- ๐ฆ On a phone box (usually on a barcode sticker).
Next:
- Go to the official Xiaomi verification site: mi.com/global/verify.
- Enter the IMEI or serial number (S/N).
- The system will show the phone model and the basic configuration, including the processor.
If Xiaomi does not provide information about the processor, use third-party services:
- IMEI.info โ shows the specifications of IMEI.
- SND Deep Info โ deciphers the Xiaomi serial number.
What to do if IMEI is not determined?
Method 5: Disassembly of the phone (extreme method)
If all the software methods failed, the last option is a physical examination of the motherboard, which is only suitable for advanced users, as it requires accuracy and can lead to loss of warranty.
What you'll need:
- ๐ง Set of screwdrivers (star) T3-T5 flat).
- ๐งฒ Screen removal suction cup (optional).
- ๐ธ Camera to capture the location of the plumes.
Step-by-step:
- Turn off the phone and remove it. SIM-map + memory-card.
- Heat the back cover with a hairdryer (temperature 60-70 ยฐ C) - this will soften the glue.
- Carefully tuck the lid with a plastic spatula, starting at the bottom corner.
- Unscrew all the screws holding the metal plate over the battery.
- Disconnect the battery plume (usually black).
- On the motherboard, find the chip of the processor โ it is the largest, usually signed as Qualcomm + model (for example, SDM660).
Where to look: The processor is located under a metal radiator (if any) or near RAM. On the Redmi Note 7, it is usually at the top of the board.
โ ๏ธ Warning: Disassembling the phone will void Xiaomi's warranty. If you're unsure of your skills, contact the service center.Also remember that improper disconnection of the battery plume can lead to a short circuit!
