How to watch the Bluetooth version on your Xiaomi phone

Modern Xiaomi smartphones are equipped with advanced wireless communication modules, but standard interface settings MIUI or HyperOS often hide from the user the exact technical specification. Many owners wonder how to see which Bluetooth is installed on their device, especially when buying new headphones or game controllers, where codec support and connection stability are important.

Knowing the version of the communication protocol is not only necessary out of pure curiosity, but also to diagnose problems with the connection of peripherals. Android system, which is the basis of the shells Xiaomi, provides several levels of access to this information, from simple system reports to hidden engineering menus. In this article, we will discuss all available methods that will help you get accurate data about your communication module.

You should understand that the Bluetooth version is not just a number, but a whole set of supported profiles and codecs, such as aptX, LDAC or AAC. These are the parameters that determine the sound quality in wireless headphones and data transfer speed. So before looking for ways to "pump" sound, make sure that your hardware supports the necessary technology.

Checking through settings and phone information

The most obvious, but often the least informative way is by using the standard settings menu. Depending on the version of the MIUI or HyperOS firmware, the path to information may vary. Usually, the user needs to go to Settings → About Phone → All settings. This displays basic information, but the specific version of the Bluetooth protocol (such as 5.2 or 5.3) is rarely listed here.

However, in some assemblies you can find detail in the menu "Status". SIM-If you click on the appropriate item, you can see a list of supported technologies. If it says Bluetooth 5.0 and higher, then your smartphone supports multiple devices simultaneously and has improved range.

⚠️ Note: Don’t blindly rely on online marketing descriptions. The Bluetooth version listed in the product specifications may be different from the actual fee set in your revision, especially if you are buying a refurbished or global device.

For a deeper analysis, you can use a search by settings. Type "Bluetooth" in the search bar and select "Bluetooth Version" (if available in your location), which is a quick way to check if the module has switched to compatibility mode with older devices, which sometimes happens after resetting.

Using the CIT Engineering Menu for Diagnostics

The most reliable method available without installing third-party software is to log into the CIT (Customer Integration Test) engineering menu, which is built into every Xiaomi smartphone and is designed to check the health of all components before selling. To get there, open the Phone app and type in the combination ##6484##.

Once you enter the code, you'll see a list of dozens of tests, and you'll find a Bluetooth item (often called the Bluetooth Test or BT), and you'll run this test, and you'll not only see the protocol version, but you'll also be able to check the antenna, scan devices, and transfer data packets, and it's a diagnostic tool that gives you access to the hardware directly.

Inside the test, a technical bar like Chip Version: QCA6174 or similar is often displayed. Knowing the chip model, you can accurately determine the maximum supported version of Bluetooth through the specifications of the manufacturer Qualcomm or MediaTek. For example, Snapdragon 8 Gen chips usually support current communication standards.

Third-party applications for detailed information

If the built-in tools seem too complex or not informative enough, Google Play will come to the rescue, applications like CPU-Z, AIDA64 or Device Info HW collect comprehensive data about the configuration of the smartphone, they read information directly from the system files of the Android kernel.

Once you install an application like CPU-Z, you need to go to the "Device" or "Network" tab, and it will clearly spell out the "Bluetooth Version" line, and the advantage of this method is that you see exactly the version that the driver is communicating to the operating system, which eliminates confusion with marketing names.

It's important to note that some applications may show a version of the Bluetooth API rather than a hardware version. For example, Android may support a Bluetooth 5.0 API even if the physical module is OLDER. However, 99% of the time on modern Xiaomi, these values are the same. Use the unique chip model identifier found in the application to search for exact specifications on the Internet.

Analysis through log files and ADB (for advanced)

For users who are not afraid of the command line, there is a method of obtaining information through debugging. USB. Connecting the phone to the computer and activating the mode USB-If you debug the developer menu, you can request a system log. Enter the adb logcat command. | grep bluetooth in the console, and you will see a stream of data about the operation of the module.

In the first lines of the log, when you turn on Bluetooth, you often see information about the initialization of the controller, and it will specify the exact version of the firmware module and the standards supported, which is difficult for the beginner, but gives the most "honest" picture of what is happening in the system without embellishing the interface.

adb shell dumpsys bluetooth_manager

This command will give you a detailed report of the status of the Bluetooth manager. Look for lines that contain Local Name or Version. This is a professional diagnostic method that engineers often use when debugging drivers. hci_command_status, This may indicate a software failure of the module.

⚠️ Note: Be careful when working with ADB. Incorrect commands can lead to unstable system operation or cyclical restart if you choose to modify system files based on the information received.

Table of conformity of versions and capabilities

Understanding the numbers in the Bluetooth version name helps you assess the potential of your Xiaomi smartphone. Below is a table that will help you decipher what exactly is behind these numbers and what benefits they give the user.

As you can see from the table, the transition from version 4.x to 5.0 gave a multiple increase in performance. Owners of Xiaomi flagships Mi and Xiaomi 13/14 series can count on support for the latest standards, which is critical for the use of high-resolution wireless codecs.

💡

If you use old Bluetooth 4.0 headphones on a new smartphone, they will work, but you won’t be able to appreciate the benefits of the new module’s improved signal and data rate.

Frequent problems and their solution

Sometimes users are faced with a situation where the Bluetooth version in the system is not determined or the module is unstable. A common cause is a driver conflict after a firmware update. In such cases, resetting the network settings helps. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile network and Bluetooth.

Another problem could be the physical damage to the antenna module after falling or getting moisture. If the Bluetooth test shows an error in the engineering menu or finds no devices around them, even though they are on, hardware repair may be required.

Also worth mentioning is the effect of protective glasses and covers. Metal cases can shield the signal, which will make the phone "think" that the module is working poorly, and reduce the transmission power. To check, remove the case and repeat the test.

💡

The stability of Bluetooth on Xiaomi depends not only on the version of the protocol, but also on the quality of the firmware and the absence of physical interference near the antenna.

The impact of Bluetooth version on autonomy

Newer versions of the protocol, such as 5.2 and 5.3, have been designed with energy savings in mind. Low Energy (LE) technology allows devices to share small data packets while remaining dormant most of the time. On Xiaomi smartphones with capacious batteries, this gives a tangible increase in running time when using fitness trackers or watches.

However, if you use older devices with a classic Bluetooth profile, the power consumption will be higher. The system automatically selects the optimal mode of operation, but the user can manually turn off Bluetooth in the Quick Settings Panel if you don't use it right now. This simple action extends the battery life.

⚠️ Warning: Constantly searching for devices in visibility (Visible to All) significantly consumes battery power and increases the risk of unauthorized connection.
