How to find out the full characteristics of your Xiaomi phone: from model to hidden parameters

Have you just bought a used Xiaomi Redmi Note 12 and want to make sure the vendor hasn't cheated on the configuration? Or are you planning to upgrade your firmware but aren't sure about the exact model of the device? Or maybe you're just curious what processor you have in your device. POCO X5 Pro and how many cores does it have? You can find out the characteristics of a Xiaomi smartphone in a dozen ways, from standard menus to engineering codes. In this article, we will analyze all the current methods, including those that work on new versions. MIUI 14 and HyperOS.

It's important to understand that the manufacturer doesn't always honestly specify the full specifications. For example, in some regions Xiaomi sells devices with reduced CPU frequencies or smaller cache volume. And in the secondary market, there are cases when under the guise of Xiaomi 13 Pro, Xiaomi 13 sells with a smaller screen size. So performance check is not just curiosity, but a way to avoid deception and optimize the use of the device.

1. Standard settings MIUI/HyperOS: fast-tracking

The easiest method is to use the system's built-in menus, and it's suitable for all models, including the Redmi, POCO, Black Shark and Xiaomi’s flagship series 12/13/14. The main advantage: you do not need to download anything or enter complex commands.

Open the Settings app (cog icon) and follow the path:

Settings → About the phone → General information

Here you will see the basic information:

• 📱 Model of device (e.g, 22101320C — Xiaomi 12T Pro)
• 🔄 Version. MIUI/HyperOS (relevant to check for updates)
• 📅 Production Date (will help determine the age of the device)
• 🔋 Battery status (new versions show the percentage of wear)

⚠️ Note: Some firmware may not have the battery status item, in which case use alternative methods in Section 4.

For more information, tap several times in a row on the item Version MIUI (or the HyperOS version. 5-7 Clicking will open a hidden menu Equipment Test where you can check:

• 🔍 Performance of sensors (gyroscope, accelerometer, compass)
• 🎤 Quality of microphones and speakers
• 📶 Wi-Fi and mobile network signal

2. Engineering codes: hidden data for advanced users

If standard settings are not enough, you can use service USSD-They work on all Xiaomi smartphones regardless of the firmware version and do not require root rights).

The most useful code is ##4636##. Once you enter it, you will be taken to the Testing menu, where you can:

• 📊 View the actual screen time (Screen-on-time)
• 🔋 Find out the current charging current (in mA) and battery voltage
• 📡 Check the signal of the mobile network in dBm (normal: -70...-100 dB)

⚠️ Note: Some firmware (e.g. global versions for Europe) may have the engineering code disabled. In this case, use the applications in Section 5.

💡

If the code doesn't work, try typing it without the last star (e.g. #4636## instead of #4636##*).

3. Through MIUI Dialer: an alternative way for older models

Xiaomi smartphones before the 2019 release (such as the Redmi Note 5 or Mi 8) were available special diagnostic mode through the Phone app, which still works on some devices, even if the engineering codes are blocked.

Instructions:

1. Open the Phone app.
2. Enter the combination: ##64663## (no stars!).
3. Press the call button (green tube).
4. Select Hardware Testing.

You'll find this menu:

• 🔧 Full Test – Comprehensive testing of all components
• 📱 Item Test – testing of individual modules (camera, speaker, vibration)
• 📊 Version – detailed information about the hardware (including a revision of the motherboard)

Version is especially useful – it indicates:

• Accurate revision of the processor (e.g., Snapdragon 8 Gen 1) SM8450-AC)
• RAM (including reserved memory)
• Screen type (AMOLED or IPS, refresh rate)

4. Diagnostic applications: CPU-Z, AIDA64 DevCheck.

If the built-in methods don't give you the full picture, third-party utilities come to the rescue, and they not only show you the specs, but they also run benchmarks, stability tests, and compare your device to other models.-3 Apps optimized for Xiaomi.

1. CPU-Z (free of charge, no advertising)

• 🔹 Shows the actual processor frequency (not the specification)
• 🔹 Displays the temperature of the chipset in real time
• 🔹 It supports all Xiaomi models, including Black Shark and POCO

2. AIDA64 (paid version - 299₽)

• 🔹 Detailed sensor information (including barometer and light sensor)
• 🔹 Disk performance test (UFS 2.1 vs UFS 3.1)
• 🔹 Export of the report to HTML/CSV compare with other devices

3. DevCheck (free, minimalist interface)

• 🔹 Shows the actual amount of memory (taking into account the redundant system)
• 🔹 Camera driver information (useful to check for GCam support)
• 🔹 Displays bootloader version (relevant for unlocking)

Example of the report from DevCheck for Xiaomi 13 Ultra:

Model: 23117PN5BC (Xiaomi 13 Ultra)
