Have you bought a used Xiaomi Redmi Note 13 Pro+ and doubt the honesty of the seller? Or want to compare the real parameters of your POCO X6 with the stated on the site? To learn the exact characteristics of the Xiaomi smartphone in 2 minutes without disassembling the case and special tools. In this article, we will analyze 7 working methods, including hidden engineering menus, official services and third-party utilities that will show even those parameters that the manufacturer does not advertise.
It's important to understand that certain characteristics (e.g. battery capacity or screen type) change over time due to wear and tear, so the data from the box or technical passport may not be as good as the actual performance, and we'll teach you to check the actual state of the iron, not just the factory specifications.
1. Android Standard Settings: A Quick Overview of the Basic Parameters
The easiest way is to look at the system menu, which won’t show you all the details, but will give you basic information about the model, software version and hardware platform, which is suitable for all Xiaomi smartphones, including Redmi, POCO and Black Shark.
Instructions:
- 📱 Open the Settings app (cog icon)
- 🔍 Scroll down and select About Phone (or About Device)
- 📋 Here you will see the model of the device (for example, 23113PN5BI For the Redmi Note 13 Pro 5G) Version MIUI and Android RAM and internal memory Assembly number (MIUI Global 14.0.5.0, etc.)
⚠️ Note: This menu does not show the actual battery capacity, processor type or camera resolution.
💡
If the "About Phone" section doesn't have "All Specification" -- your firmware has been modified, which could mean custom MIUI or unofficial software.
2. Secret engineering codes: data directly from the system
Manufacturers hide service menus from users, but they can be accessed through special USSD-These commands work for all Xiaomi, regardless of the model and firmware version, and the key is to type them accurately, without spaces.
Basic codes for performance verification:
| Code. | What shows | Example of data |
|---|---|---|
| ##4636## | Information about battery, network, use | Charge level: 87%, temperature: 34°C, network type: LTE |
| ##232338## | MAC-Wi-Fi address and Bluetooth | Wi-Fi: 00:11:22:33:44:55 |
| ##2664## | Screen test (colors, sensor) | White/Black/Color Screen, Multi-Touch Check |
| ##06## | IMEI devices | 861234567890123 (15 digits) |
🔹 How to enter codes: Open the Phone app, go to the dial keyboard and type the combination. The menu will open automatically - no buttons need to be pressed.
What to do if the code doesn't work?
Application "Equipment Test" (Hardware Test)
MIUI has a hidden hardware diagnostic app that shows real-world (rather than claimed) performance, from CPU clock speed to battery wear, and even the Hall sensor (for foldable models) or infrared port.
How to open it:
- Open the Settings. → The phone.
- Slip 5 times on the item Version of the kernel (or Assembly Number)
- Enter password: 123456 (by default)
- In the menu, select Hardware Test.
What the app checks:
- 🔋 Battery: real capacity (for example, 4850 mAh instead of the declared 5000 mAh), number of charging cycles, temperature
- 🖥️ Screen: resolution, refresh rate, support HDR
- 📡 Network: supported ranges 4G/5G, signal strength
- 🎮 Sensors: gyroscope, accelerometer, compass, barometer
Third-party applications: CPU-Z and AIDA64
If standard methods are not enough, use professional utilities that will show hidden characteristics that are not displayed in the system menu: processor architecture, type of RAM, proprietary chips (for example, Xiaomi’s Surge for charging).
Top.-3 apps:
- 📊 CPU-Z: Shows a real-world model of the processor (e.g., Snapdragon) 7s Gen 2 instead of the generalized "8-core" Displays the clock frequency of each core Tests performance in benchmarks
- 🔍 AIDA64: Detailed sensor information (even light sensor) Real-time temperature of all components Support for infrared port and other rare modules
- 🔋 AccuBattery: Analyzes battery health according to controller data Shows real capacity (adjusted for wear) Tracks charging cycles
⚠️ Note: Some apps (such as AnTuTu Benchmark) may show incorrect data on performance-locked smartphones (such as on smartphones with a performance lock). POCO Before the test, turn off all optimizations in Settings → Battery.
☑️ Preparation for testing
5. IMEI check: data from the factory
Each Xiaomi smartphone has a unique IMEI, which can be used to identify the original specifications specified by the manufacturer, which is useful if you suspect that the device has been re-flashed or modified.
How to check:
- Find out about IMEI: via code *#06# Or in Settings → About Phone → General information
- Go to one of the services: IMEI.info (paid report) SNDeepInfo (free for Xiaomi) Official site Xiaomi (requires authorization)
- Dates of production
- Original model (e.g. M2304W12C for Xiaomi 13 Lite)
- Regional firmware (Global, China, India)
🔹 What to find: If the report indicates the model Redmi Note 12 Pro Speed, and the case says Redmi Note 12 Pro+ — This is a relabeled device, and these phones are often sold as "exclusive versions," even though they're identical to the basic models inside.
Disassembly and visual inspection: for experienced users
If software methods don't give you the answers -- like knowing the exact battery model or the type of screen you want to use -- you'll have to look inside the device, which is a risky way to do it, only for those who are willing to lose the warranty.
What you can learn when disassembling:
- 🔋 Battery: Real-life manufacturer (e.g., battery, ATL or Sunwoda) Production date (printed on battery) Charging controller type
- 🖥️ Screen: Matrix model (e.g. Samsung) E4 or BOE) Presence OLP-Polarizer (protection against peeping)
- 📱 Fee: Type of memory (UFS 2.2 or UFS 3.1) Passive cooling (graphite plates)
⚠️ Note: On Xiaomi models with liquid metal cooling (for example, Black Shark 5 Pro), self-disassembly can lead to a leak of the coolant and the device fails.
💡
If you're not sure about your skills, don't take your phone apart on your own. Most of the features can be programmed and left to the specialists for visual inspection.
Comparison with official data: how to detect fraud
Even if all tests show the same numbers, it does not guarantee the honesty of the seller. For example, fake Xiaomis often mimic the characteristics in the software, but in fact use weak hardware. To avoid fraud, compare the data with official specifications.
Where to get the reference characteristics:
- 🌍 Xiaomi official website: Go to mi.com Find your model in the Phones section Contrast processor, cameras and battery
- 📄 GSMArena: Database with detailed tests: gsmarena.com There are data on benchmarks and autonomy
- 🛠️ XDA Developers: Forums with real-world features: forum.xda-developers.com Users share test results on custom firmware
🔹 Signs of forgery:
- In Settings → The phone is a model that is not on the official website.
- In the tests of AnTuTu or Geekbench results are 30-40% below the benchmark
- When you enter an IMEI on mi-account.xiaomi.com, the site gives an error
If you find discrepancies, ask the seller for checks or a warranty card. Fake Xiaomi often sells with fake documents that indicate a non-existent model (for example, the Redmi Note 12 Turbo S).
