Modern smartphones like the Xiaomi Redmi 9 are using wireless protocols to transmit data, and Bluetooth plays a key role here: Every day we connect headphones, fitness bracelets, car stereo systems or smart watches to the phone, but over time, the phone accumulates a list of previously used gadgets that are no longer needed or have been replaced with new models.
The accumulation of unnecessary profiles can cause communication module malfunctions or simply make it difficult to find relevant devices. Users often wonder how to correctly and completely remove a bluetooth device on Android to clear connection history. In this article, we will discuss in detail the process of removing conjugated gadgets on the MIUI shell installed on Redmi 9.
The pair list cleaning procedure is a regular feature of the Android operating system, but Xiaomi’s firmware has its own menu layout nuances. We’ll look at the standard method through settings, and also touch on possible problems when the system keeps the device from forgetting. Understanding these processes will help you maintain order in your smartphone’s communication settings.
Why You Should Remove Old Devices from Bluetooth List
Many Redmi 9 owners ignore the list of conjugated devices until they encounter connection problems. Caching data about old gadgets can take up system resources, albeit in a minimal amount. Moreover, having dozens of entries in the Bluetooth database can slow the process of scanning available devices in range.
There's also a security aspect: If you sold your old wireless headphones or gave a fitness tracker to another person, the residual recording in your phone could theoretically contain encryption keys. Deleting the device ensures that communication between gadgets is completely and irrevocably severed, especially when handing the phone over to third parties or before selling the smartphone itself.
Often, deletion is required when the device is behaving incorrectly, for example, headphones may not automatically connect or make strange sounds when trying to connect, in which cases, completely "forgetting" the device and re-pairing often solves the problem of software conflicts.
- 🎧 Clearing up conflicts: Removing an old profile helps eliminate errors when reconnecting the same gadget.
- 🔒 Privacy: Removing data access for devices you no longer own or use.
- 🚀 Optimization: Accelerating the wireless module by reducing the database of known devices.
Standard Removal Procedure Through Settings
The main and most secure way to remove the extra device is to use the built-in system menu. First, unlock your Xiaomi Redmi 9 screen and go to the home screen. Find the Settings icon, which usually looks like a gear, and click on it. MIUI interface may vary depending on the version, but the logic remains the same.
In the settings menu that opens, you need to find the wireless connection section, which is called Bluetooth in most firmware versions. Sometimes this item may be inside the Connect and Sharing tab. Once you log in, make sure that the Bluetooth activation slider is switched to the On position, otherwise the list of devices may not be available for editing.
Below the switch, you'll see a list under the heading "Coupled devices" or "My devices." This shows all the gadgets your phone has ever connected to. Find the name of the device you want to remove. This could be Car Kit, Headphones or a brand name like JBL or Galaxy Watch.
To remove the device, you need to click on the device name or arrow next to it. An additional menu of properties of a particular gadget will open. At the bottom of the screen or in the upper right corner (depending on the version of MIUI), there will be a button with the garbage bin icon or the inscription Delete.
☑️ Pre-deletion check
Solving problems: if the delete button is inactive
Sometimes users are faced with a situation where the device appears in the list, but you can not click on it or the delete button is missing. This often happens if the background process tries to communicate with the gadget. For example, if the smartwatch is in range and trying to synchronize data, the system can block the connection break.
In this case, the first step should be to completely shut down Bluetooth. Transfer the slider to the Off position, wait 5-10 seconds and turn it on again. After that, try logging in to the device menu again. If that didn't work, try rebooting the Xiaomi Redmi 9 itself. Reboot clears temporary files and stops the suspended services.
Another reason may be the work of a third-party app. Some fitness trackers require the installation of a separate companion app (e.g. Mi Fit or Zepp). If such an application is active, it can block the device from being removed from system settings. Try to force the application to stop or remove it temporarily to break the connection.
⚠️ Note: If the device is not removed, make sure it is not used by other profiles on the phone (if there are more than one) or is not a system input device necessary for the phone to work.
It's also worth checking if the flight mode is on, and although it usually shuts down all the modules, sometimes activating it and then turning it off helps reset the network stack, and if the problem persists, a deeper cleanup may be needed, which we'll talk about later.
What to do if the device is "ghost"?
Resetting network settings as a radical method
If standard methods don’t work and dead devices continue to hang on the list, you can use the network reset feature, a more serious move that will affect not only Bluetooth, but also Wi-Fi and mobile data settings. On Redmi 9, this feature is deep on the menu.
To reset, go to Settings, then select About Phone or search by settings by typing the phrase "Reset." You need Wi-Fi, mobile networks and Bluetooth Reset. The system will warn you that all saved passwords from Wi-Fi and Bluetooth pairs will be deleted.
Once confirmed, the phone will restart the network modules, which will ensure that all devices are removed from the list, including those that caused errors, and is effective in software failures when the connection database is damaged.
| Parameter | Before dumping. | After discharge |
|---|---|---|
| Bluetooth Listing | Contains errors | Empty. |
| Wi-Fi passwords | Save. | Removed. |
| APN settings | Modified. | Standard. |
| Mobile Internet | It's working. | It's working. |
💡
Before resetting your network settings, be sure to write down passwords from important Wi-Fi networks, as it will be impossible to restore them from the phone’s memory after this procedure.
Using the Engineering Menu for Diagnostics
For advanced Xiaomi users, there is an option to access the engineering menu where you can test the Bluetooth module. This is not a direct way to delete, but it helps to determine whether the module itself is working. To get into the menu, open the Phone app and type in the code ##6484##.
In the CIT menu that opens, look for Bluetooth. Once you run the test, you can see if the device module sees and responds to commands. If the device is not removed or the test is flawed, the problem may be hardware.
It's safe to use this menu, unless you change the settings that are not related to testing, but if you're not sure what you're doing, you'd better limit yourself to standard settings. The engineering menu is a diagnostic tool, not a daily interface management tool.
- 🛠 Access: Entering code in the call app opens the hidden diagnostic menu.
- 📡 Testing: Allows you to check the operation of the antenna and communication module separately from the operating system.
- 📉 Logistics: In some versions, you can see logs of connection errors, which is useful for service centers.
⚠️ Warning: Do not change the values in the engineering menu unless you know exactly what they are responsible for. This may cause your Redmi 9 radio module to malfunction.

💡
Cleaning the Bluetooth list regularly is a good habit to keep wireless connections stable on your Xiaomi Redmi 9.
To sum up, managing the Bluetooth list on Xiaomi Redmi 9 is a simple and straightforward process. The key is knowing where to look for the right settings in the MIUI shell. Deleting unnecessary profiles in a timely manner helps avoid conflicts and ensures that the gadgets you need are connected quickly. If standard methods do not help, there is always the option of resetting the network settings that returns the system to factory parameters in this area.
Remember that digital hygiene is important not only for files and photos, but also for system settings. A clean list of devices is less of a burden on the search process and more predictable behavior of your smartphone at critical moments when you need to quickly connect headphones or headset in the car.
