How to see the characteristics of the Xiaomi phone: all ways from A to Z

Have you bought a Xiaomi, Redmi or POCO smartphone but aren’t sure what the real-world specs are? Or do you want to check if the hardware matches the stated parameters before buying a used device? In this article, we’ll look at all the possible ways to view technical data, from standard MIUI menus to hidden engineering commands and third-party utilities.

Manufacturers sometimes understate or overstate marketing materials, and aftermarket sellers may deliberately hide defects (e.g., a replaced battery or a non-original processor). Our methods will help to identify inconsistencies in 2 minutes - without root rights and complex manipulations. MIUI, Which is not available on other Android smartphones.

1. Standard method: About Phone menu in MIUI

The most obvious, but not always informative, method is that it will show basic data, but it hides half the technical details.

Open Settings → About the phone. Here you will see:

• 📱 Device model (e.g. Redmi Note 12 Pro)+ 5G or POCO F5)
• 🔢 Version. MIUI Android (relevant to checking for updates)
• 🔋 Battery capacity (but only nominal, without data on wear)
• 📊 Total memory (without breakdown into system and user)

⚠️ Note: In this menu, Xiaomi often rounds up values. For example, instead of a real 6.67 inch screen, you can say “6.7” and instead of 8 GB of RAM, you can just say “6.7” instead of “8 GB of RAM «8GB». For accurate data, use the methods below.

💡

Click 5 times in a row on the line "Version" MIUI» — This will activate the hidden developer mode (required for some of the methods in this article).

2. Secret engineering codes for Xiaomi

The manufacturer hides detailed information behind special USSD-These codes work on all Xiaomi, Redmi and other smartphones. POCO regardless MIUI. Enter them in the standard application "Phone»:

The most useful code is ##4636##. After you enter it, select the Battery Information tab.

• 🔋 Real charge level (in millivolts, not percentages)
• 🌡️ Battery temperature (normal: 25-40)°C)
• 🔄 Charging state (e.g., “charged (USB)»)

3.Security app – Hidden MIUI data

The company's Security app hides a section with detailed information about the device, and many users are unaware of its existence, although it is on all Xiaomi smartphones:

Instructions:

1. Open the Security app (if not, download from Google Play).
2. Go to Optimization. → ⚙️ (gear-up) → Device information.
3. Scroll down to the "Hardware Information" block.

Here you will find:

• 🖥️ Exact CPU name (e.g. Qualcomm Snapdragon 7)+ Gen 2, not just an 8-core»)
• 📏 Screen resolution in pixels (for example, 2400 × 1080)
• 🎮 Type of graphics processor (Adreno 725, Mali-G78 etc.)
• 📡 Network support (e.g, 5G NR: n1/n3/n5/n8...)

4. Third-party applications for in-depth analysis

If standard methods are not enough, install specialized utilities that will show the data that Xiaomi hides from the user (for example, the real capacity of the battery after wear or type of memory). UFS/eMMC).

Top.-3 tested applications:

• 🔍 CPU-Z — shows detailed characteristics of the processor, including the process (for example, 4 nm) and core frequencies.
• 📊 AIDA64 — It displays the full specification, including sensors, codecs, and even the temperature of individual components.
• 🔋 AccuBattery - analyzes the state of the battery: real capacity, number of charging cycles and wear.

⚠️ Attention: Apps like CPU-Z They may show incorrect CPU data on some Xiaomi models (e.g. Redmi Note 11) if the cores are running in energy-saving mode.

Item “System fee" → motherboard|Item "Battery" → Real capacity (compare with the stated capacity)|Item “Sensors" → operability of the gyroscope/accelometer|Item “Network" → supported Wi-Fi ranges (2.4/5/6 GHz)-->

5. Check through Fastboot mode (for advanced)

If the phone doesn’t turn on or you suspect a replacement of components (such as a motherboard replacement), use Fastboot mode.This method requires a computer and a USB cable, but gives 100% accurate information about the hardware.

Instructions:

1. Turn off the phone.

4. Enter the command: fastboot getvar all

In the answer, look for the lines:

• product: - exact device model (e.g. sweet for Redmi Note 10 Pro)
• Battery-type: Type of battery (original or fake)
• secure: - bootloader lock status (yes or no)

💡

If you see secure: no in the fastboot getvar all response, it means that the bootloader is unlocked, and these devices are often sold after repair or customization, which can void the warranty.

6. How to check the originality of the components

One of the main problems when buying used Xiaomi smartphones is replacing parts (battery, screen, camera).

Battery:

• 🔋 In AccuBattery, compare the actual capacity to the declared capacity, for example, if the box says 5,000 mAh and the app shows 4200 mAh, the battery is worn out or fake.
• 🔍 Look at the date of production (battery printed) If the phone is released in 2023 and the battery is in 2019, it's been changed.

Screen:

• 📱 Enter the code ##6484## and select Screen Test. If broken pixels or bands appear, the matrix is unoriginal or damaged.
• 🔦 Light a flashlight at an angle: on the original screens Xiaomi no air bubbles between the glass and the matrix.

Camera:

• 📸 Take a picture of a piece of paper with fine text, and on non-original modules, the text will be blurred at the edges.
• 🔍 In the annex CPU-Z Check the camera model (Camera section) if it doesn't match the official specification, the module is replaced.

7. Online IMEI Check: Myths and Reality

Many people recommend checking the specs through services like imei.info, but this method doesn’t work for Xiaomi.

✅ What will he tell? IMEI:

• 📋 Basic model information (e.g. Redmi Note 12)
• 📅 Date of production (but not date of sale!)
• 🔄 Lock status (if the phone is blacklisted by operators)

❌ What won't show IMEI:

• 🔋 Battery capacity or processor type
• 📱 The state of the screen, camera or other modules
• 🔄 Firmware version or update history

⚠️ Warning: Fraudsters often fake stickers with IMEI Always check the number by dialing *#06# with what is on the package and under the battery (if removable).
