How to find out the full characteristics of the Xiaomi Redmi phone

Owning a modern smartphone involves not only using its basic features, but also understanding the potential hidden inside the case. Often users buy Xiaomi brand devices or its sub-brand Redmi, focusing on attractive price and high-profile marketing statements, but not going into technical details. However, knowing the exact hardware configuration is necessary to optimize work, select compatible accessories or when you have problems with performance.

There are many ways to access this information, ranging from simple visual checks on menus to sophisticated diagnostic utilities for engineers. Standard methods can hide some nuances, such as the actual CPU frequency or the type of screen array used. In this article, we will take a detailed look at all the options available so you can get comprehensive technical data about your device without having to open it.

Whether you’re a regular user or an advanced enthusiast, being able to read the specifications of a gadget will help you better understand its behavior.We’ll look at the regular tools of the Android operating system with the shell of MIUI or HyperOS, as well as third-party tools that give access to hidden parts of the system.

Checking the main data through the settings menu

The most obvious and affordable way to learn basic information about your smartphone is to use an embedded interface. Electronics manufacturers bring key parameters to the fore so that the user can quickly navigate, and you just unlock the screen and find the system settings icon, which usually looks like a gear.

The list that opens up should scroll down to "About the phone" or "About the device" and that's where the primary summary is: the processor model, the amount of RAM and internal memory, and the operating system version, but it's worth considering that it only displays the basic characteristics, without detailing by component manufacturers.

For a deeper dive into the settings, you can use the extended menu. If the standard partition isn't enough, try looking for "All Specifications" or similar, which is often hidden in the submenu, where you'll see screen resolution, battery capacity in milliamp hours, and even sensor information.

💡

Note that the amount of available memory is always less than the stated amount, as part of the space is reserved for system files and recovery partitions.

It is important to distinguish between marketing names and real-world technical options, for example, the menu may simply say “8 GB of memory”, but it is not specified whether this memory is LPDDR4X or faster LPDDR5. For normal use, this difference may not be noticeable, but when working with heavy applications it becomes critical.

Use of engineering menus and hidden codes

The Android operating system, which runs Redmi smartphones, has built-in diagnostic tools that are hidden from the eyes of the average user. USSD-commands entered in the Phone app, which allows you to access logs, hardware tests and detailed information about the hardware.

To get into the testing menu, open the dialer and dial the combination ##6484##. This command activates the CIT (Customer Information Test) mode developed by Xiaomi plant engineers. Here is a complete list of all hardware modules, from the vibrator and flashlight to the communication modules and touchscreen.

In this section, you can not only see the status of components, but also start them actively validating. For example, if you select Version, you will see a detailed summary of all installed modules, including driver versions and firmware assembly dates, which is especially useful when buying a used device to make sure the originality of the parts.

⚠️ Warning: Be careful when changing the settings in the engineering menu.Accessal reset of sensor calibration or changing the parameters of the radio module can lead to malfunctioning of the phone.

Another useful code is ##4636##. It opens the test menu, where you can see detailed battery information, usage statistics and Wi-Fi data. The Battery Information section often displays the actual capacity, current charge and battery health status, which is not always available on the regular menu.

Third-party applications for detailed diagnostics

The regular tools are good, but they often provide information in an anonymized form. If you need to know the exact model of the screen matrix, the manufacturer of the camera sensor, or the actual frequency of the CPU cores at the moment, you better use specialized software, such applications read data directly from the system files and output it in a convenient format.

One of the most popular and reliable tools is the CPU-Z application. It is free, requires no advertising and gives comprehensive information about the SoC (System on Chip). The System tab will show the exact name of the processor, its architecture and current clock speed. The Device tab will tell you about screen resolution, pixel density and real memory available.

Another powerful tool is AIDA64, which provides perhaps the most detailed picture of hardware, showing the temperature of each CPU core, the voltage in the various power chains, and the exact model of the battery and the number of cycles it recharges. It's an indispensable monitoring tool for enthusiasts.

Also worth mentioning is the Device Info HW app, which is unique in that it can identify a specific component manufacturer even if they have the same specifications, for example, it will show whether you have a Samsung or BOE screen and which camera module is installed – this is important for assessing the quality of a photo.

Receiving information through connection to a computer

If the phone doesn't turn on or the touch screen doesn't respond to touch, you can learn the characteristics through a connection to a PC. The computer sees the connected device as an external module and can read its identifiers even without loading the operating system in full mode. This will require a USB cable and, in some cases, installed drivers.

The easiest method is to use a Windows Device Manager, plug your smartphone in with a cable and see how it defines itself in the system. Often, the device name in the "Sound Processing Devices" or "USB Controllers" section shows a model of a processor or audio codec, but this method only gives fragmentary information.

More advanced option - using the program ADB (Android Debug Bridge. It's Google's official tool for developers.-tools on the computer and enable debugging USB On the phone, you can enter the command in the console:

adb shell getprop | grep ro.product

This command will display a list of product properties, including model, brand and build characteristics. To get complete information about the hardware through ADB, you can use the adb shell cat /proc/cpuinfo command, which will show a detailed description of the processor, or the adb shell dumpsys battery to obtain battery data.

⚠️ Attention: To work with ADB You need to turn on the developer mode. Only do this if you understand what these settings are for, because errors can disrupt the stability of the system.

Analysis of packaging and documentation of the device

The box from a Xiaomi or Redmi smartphone is not just a container, but a certified data source. The sticker on the end or bottom of the box always shows the exact model, article, memory and region of release.

Here you can find information about the supported cellular frequencies, which is critical when buying a device from abroad. For example, Chinese versions may not support some LTE bands used in Europe or Russia.

Inside the box is often a brief instruction or warranty card, which duplicates the main characteristics, and saving the box and documents is especially important if you plan to sell the device in the future - having a full package increases its liquidity and customer confidence.

Compare the data on the box to the data on the phone. If the processor model or memory size doesn't match, it could indicate a flashing device or replacement of internal components in the service center. The discrepancy between the data on the box and the system is the first sign that the phone may have been repaired or repaired.

Summary table of popular models Redmi

For quick orientation in the model range, we will give a comparative table of characteristics of some popular series, which will help to understand what parameters are standard for different price segments of the brand.

This table is an introductory one, as dozens of modifications with different characteristics can come out in a series, and always check a particular model by IMEI or through the settings menu to avoid making mistakes in expectations.

💡

Knowing the exact model of the processor and the type of screen matrix is more important than just the name of the smartphone series, since completely different components can stand inside the same line.
