Owning a modern smartphone from Xiaomi involves not only active use of applications, but also periodic check of the technical condition of the device. Often users need to find out the exact model of the processor, the firmware version, the number of battery charging cycles or simply verify the authenticity of the gadget through IMEI. The standard settings menu gives only superficial information, hiding many important technical parameters.
Understanding how to view Xiaomi phone information is critical when buying a used device, diagnosing malfunctions, or before reselling, and MIUI and the new HyperOS have multiple levels of data access, from basic to deep engineering, and we'll look at all the ways we can get that information.
In this article, you will find not only standard menu paths, but also special codes that open access to hidden parts of the system, which allow you to see the real state of the hardware, which is not always displayed in the standard sections of the "About the phone".
Basic information in the settings menu
The most obvious and safe way to learn the basic features is through the standard system menu, which displays the data you need for everyday use: the Android version, the MIUI build number, the amount of RAM and internal memory, and you just have to open the Settings app and scroll to the bottom.
The About Phone section provides a summary of the information. By clicking on the MIUI or Xiaomi logo several times in a row, you can see the animation or get into additional settings (depending on the shell version), and it often shows the exact code name of the model, which may differ from the marketing name.
If you're interested in space, go to Warehouse, and it shows how many gigabytes of apps, photos, and system files are occupied, which is an important parameter, because overflowing internal memory is a common cause of slowing down a smartphone.
⚠️ Note: The free memory data in the menu may be slightly different from the real value due to the features of the file system and the blocks reserved by the system%.
For more detailed information about the processor and sensors, this menu often includes All specs or Full specs, where you will find screen resolution, pixel density, and supported communication standards, which are useful when comparing your device to other models on the market.
💡
The standard menu provides only general data, hiding the battery’s technical statistics and deep iron parameters.
Using secret codes for diagnosis
The engineering menu is a powerful tool that is hidden from the eyes of the average user, and accessed through a set of special tools. USSD-This method allows you to access hardware tests and detailed statistics that are not displayed in the standard interface.
The main code for logging into the engineering menu is ##6484##. Once the last digit (*) is dialed, the menu will open automatically, without having to press the call button. Here are the tests for all components: screen, speakers, microphone, vibrator and sensors.
Another useful code is ##4636##. It opens the test menu, where you can see detailed battery information, usage statistics and Wi-Fi connection data. In the Battery Information section, you can often see the temperature, voltage and charge status in real time.
What do I do if the codes don't work?
There is also a code *#06# that displays the IMEI-all SIM card codes and MAC-This is critical information for checking the device against databases for theft or locking. Write down this data or take a screenshot to be stored in a safe place.
Analysis of battery status and charge cycles
One of the most important parts of the phone's information is its state of autonomy. Over time, the capacity of the lithium-ion battery declines, and knowing the exact number of recharge cycles is essential to understanding the residual life, which is often hidden in the standard MIUI menu.
To see the battery statistics, you can use the engineering code ##6485##. In the window you are interested in the parameter MB_06 (Health status, which shows the battery status, and MF_02 or MF_05, If the Health value is "Good," then the battery is fine.
An alternative is to use third-party utilities such as AccuBattery or CPU-Z. These applications collect data in the background and after a few days of use provide a more accurate estimate of the actual battery capacity compared to the passport.
| Parameter | Where to find (Code) | Normal value. | Description |
|---|---|---|---|
| Condition (Health) | ##6485## | Good | General state of battery chemistry |
| Charge cycles | ##6485## | < 500 | Number of complete cycles 0-100% |
| Temperature. | ##4636## | 25-35°C | Current battery heating at rest |
| Tension. | ##4636## | 3700-4200 mln | Current voltage of the element |
💡
Don’t leave your phone charging 100% overnight on a regular basis, which accelerates battery chemistry degradation and increases the number of micro-charge cycles.
It is important to understand the difference between passport capacity and real capacity. 2-3 During the period of active operation, the actual capacity may be 70-80% from the claimed charge, which leads to a faster discharge, if the charge cycles are more 800, You should consider replacing the battery.
Obtaining detailed data through applications
When built-in tools are scarce, specialized Google Play apps come to the rescue, and they can read data directly from the Android kernel system files, providing information that Xiaomi hides in standard menus.
One of the best tools is the CPU-Z app. It shows the exact SoC model, the current core frequency, the loading of each thread in real time, as well as detailed information about the sensors. The Device tab will show the screen resolution, pixel density and available RAM.
AIDA64 provides even deeper analysis, which can show the temperature of each component separately (CPU, GPU, Battery), camera resolution, and even network data, and is a professional tool for fully diagnosing a smartphone.
- 📱 CPU-Z: Ideal for checking processor, frequencies and base sensors.
- 🔋 AccuBattery: The Best Choice to Analyze Battery Health and Charging Speed.
- 📡 Network Cell Info: For in-depth analysis of signal quality and operation of communication modules.
The seller can claim that there is a Snapdragon processor inside, and the app will instantly show that a cheaper MediaTek or Helio is installed if the device has been glued or modified.
Authentication and Service Information
The market is full of fakes, so the question of "how to see information about Xiaomi phone" is often associated with checking the originality. IMEI-Find the box from the device, it should have a sticker with IMEI. Compare these numbers with those displayed by the code *#06# and the About Phone menu.
If the numbers on the box and in the system are different, the phone is likely to be assembled from different parts or refurbished without proper marking. IMEI You can check on the official Xiaomi website in the authentication section.
⚠️ Note: If you enter the code IMEI on the official website you see the message "Not found" or the data on the model do not match, this is a sure sign of a counterfeit device or a "gray" build.
You also need to check the activation date and warranty balance, and for that, Xiaomi has Check Warranty Status on its official website, and if you type in an IMEI, you'll know when the device was first activated, and if the phone is "new" but the warranty expired six months ago, that's a question.
Collecting logs and error reports
For advanced users and developers who encounter software errors, you may need to create a full report on the state of the system. MIUI has a built-in bug report creation function, you can find it in the Advanced Settings menu → For developers (if menus are included) or through a special service & feedback application.
In the Services & feedback app, select "Send a report" and the system will collect logs of recent events, list of installed applications, hardware configuration and crash history, which can be analyzed independently or sent to technical support.
adb shell dumpsys batteryFor users familiar with USB (ADB) debugging, the command above will allow you to get a text report on the battery status directly on your computer, which gives even more detailed data than is displayed on the phone screen, including the exact values of consumption current and charging status.
