How to find out the characteristics of the Xiaomi phone: from basic information to hidden parameters

You bought a Xiaomi smartphone and want to know what its "entrails" are? Or you plan to sell the device and you need to honestly specify all the parameters in the ad? Or maybe just curious, what processor is in your Redmi Note 12 or how many megapixels the main camera POCO X5 Pro? In this article, we will analyze all possible ways - from standard MIUI menus to engineering codes and third-party utilities.

The manufacturer often hides some technical data deep in the system, and some parameters (such as the actual battery capacity or screen version) and does not display in the user interface. We will show you how to get to this information without root rights and the risk of damaging the device, and you will learn what characteristics it is important to check when buying a used phone, so as not to run into a fake or “repaired” device.

Standard MIUI settings: basic information

The easiest way is to look at the Settings menu, and it shows you the basic parameters that most users need: model, firmware version, storage, etc. But the data here is incomplete — for example, you won't see the type of processor or the refresh rate of the screen.

To open the section with characteristics:

• 📱 Open the Settings app (cog icon on the desktop).
• 🔍 Scroll down and select About Phone (or About Device in New Versions) MIUI).
• 📋 Tap on the item Phone Characteristics or Specifications.

Here you'll see:

• 📅 Model of device (e.g, 2201116PI For the Redmi Note 11 Pro+ 5G).
• 🖥️ Version. MIUI and Android, for example, MIUI 14.0.5 based on Android 13).
• 💾 Total memory (including built-in and operational).
• 🔋 Battery capacity (but not always the actual value is displayed!).

⚠️ Note: Some firmware (especially global) may not have phone specifications.

💡

If you need to quickly copy the device model to search for drivers or firmware, hold your finger on the model name in the About Phone menu – the Copy option will appear.

2. Engineering menu: hidden parameters (codes ##)

For advanced users, Xiaomi has an engineering menu where you can find data that is not in the standard settings. USSD-Important: these commands do not delete data or break the phone, but changing the settings in the engineering menu without experience can lead to unstable operation of the device.

Basic codes for viewing characteristics:

• 🔢 ##4636## - information about the battery, network, usage statistics.
• 📡 ##464## - Camera test (shows real sensor resolution).
• 🔋 ##2664## - battery test (capacity, voltage, temperature).
• 🖥️ ##225## - Data on screen calibration (color temperature, brightness).

How to use:

1. Open the Phone app.
2. Enter the code (as if dialing) and press the call button.
3. Wait for the menu to open (it can take 5-10 seconds).

⚠️ Note: On some models (e.g, POCO F5 Xiaomi 13T) The engineering menu can be blocked by the manufacturer, in which case the codes will not work.

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

If standard methods are not enough, third-party utilities will come to the rescue, and they show the most complete information, from the processor model to the supported Wi-Fi frequencies.-3 Appendices and highlight their pros and cons.

The best programs for Xiaomi:

• 📊 CPU-Z — It's a classic of the genre, GPU, Memory, sensors and even battery information (including the number of charging cycles) download to Google Play.
• 🔧 AIDA64 — It displays the temperature of the components, the Linux kernel version, the codec it supports, and even the data on the system. SIM-Download it to Google Play.
• 🔍 DevCheck is a user-friendly interface with data visualization, showing the actual refresh rate of the screen (rather than the declared), the type of memory (UFS 2.1/3.1) and Bluetooth version. Download to Google Play.

Example of data from CPU-Z for Xiaomi 12T Pro:

Processor: Qualcomm Snapdragon 8+ Gen 1 (4 nm)




Cores: 1x3.2 GHz (Cortex-X2) + 3x2.75 GHz (Cortex-A710) + 4x1.8 GHz (Cortex-A510)




GPU: Adreno 730




RAM: 12 GB (LPDDR5)




Memory: 256 GB (UFS 3.1)

Processor model (whether there is a substitution for a weaker one)

Real battery capacity (compared to the declared)

Number of charging cycles (more than 500 – a reason to bargain)

Type of memory (UFS 3.1 faster than UFS 2.2)-->

4.The official site of Xiaomi: comparison of models

If you don’t just want to know the specifications of your phone, but compare it to other models, the best source is the official Xiaomi website. Here the data is 100% accurate (as opposed to third-party resources where there may be errors), but there is a caveat: the site specifies factory specifications, which may differ from the real ones after updates or modifications.

How to find your own model:

1. Go to the official Xiaomi website.
2. In the menu, select Products. → Smartphones.
3. Find your series (like the Redmi Note 12) and click on the model.
4. Scroll down to the Specifications block.

What you can find out is useful:

• 📏 Exact size and weight (important for covers and holders).
• 📷 Full camera specifications (aperture, pixel size, support) 4K).
• 🔌 Types of charging (e.g, 120W HyperCharge Xiaomi 11T Pro).
• 🛡️ Protection (IP53, IP68 etc.).

⚠️ Note: On the Chinese version of the site (mi.com/cn) It can be specifications other than global models. K50 China supports 5G two-way SIM-maps, and the global version POCO F4 GT — only one.

5. ADB-Teams: for advanced users

If you're ready to dive into the technical wilds, ADB (Android Debug Bridge) will open up all the hidden parameters of the system, which requires a computer connection and basic command line knowledge, but provides the most accurate information, including hardware data, that even specialized applications do not show.

What you can learn through ADB:

• 🔧 Real-life motherboard model (useful for authentication checks).
• 📡 Supported ranges 4G/5G (travel-related).
• 🔋 Battery condition (charge cycles, wear and tear).
• 🖥️ The screen resolution and its manufacturer (Samsung, BOE etc.).

Example of teams:

adb shell getprop ro.product.model #Model


adb shell cat /proc/cpuinfo # Processor information




adb shell dumpsys battery # Battery data




adb shell wm size # Screen resolution

Instructions for connection:

1. Download ADB Tools and unpack it on your computer.
2. Turn on USB Debugging on your phone: Settings → About Phone → MIUI version (tap 7 times to become a developer), then Settings → Additional → Developers → Debugging over USB.
3. Connect your phone to your PC and run the command line in the folder with ADB.
4. Enter the commands from the example above.

💡

ADB is the only way to know the screen manufacturer (e.g. Samsung AMOLED vs BOE) and the actual battery capacity after wear, and this data is critical when buying a used phone.

6.How to check the characteristics before buying used Xiaomi

When you buy a phone from hand, checking the performance is not a whim, but a protection against deception. Fraudsters often give Redmi as POCO, replace batteries or processors, and we have compiled a checklist to help avoid problems.

What to check:

• 🔍 Device model (should match the box and settings). Use code ##44336## to check.
• 🔋 Battery status (capacity and charging cycles) AccuBattery app will show real wear and tear.
• 📱 Serial number (must match on the box, in settings and under the battery) can be checked on the official website of Xiaomi.
• 🔧 Performance. Run the test in AnTuTu and compare it to the model reference values.

Red flags (indications of deception):

• 🚩 The model in the settings does not match the inscription on the box.
• 🚩 Battery capacity in #2664## is much lower than claimed (for example, 3,500 mAh instead of 5000 mAh).
• 🚩 V CPU-Z processor of another model (for example, Snapdragon) 778G Instead of Snapdragon 870).
• 🚩 The phone "can't see" one of the SIM-card 5G (Possibly a lockdown by the operator).

💡

Before you buy, ask the seller to remove the screen protection and inspect the device for autopsy marks. If there are scratches around the screws on the back cover, the phone was taken apart (possibly changed the battery or motherboard).
