Modern Xiaomi Redmi smartphones operate in a rich wireless environment, where constant scanning and pairing with various gadgets inevitably accumulates digital “garbage”. When the list of paired devices becomes too long, the operating system can start to work unstable, and the process of finding new devices can take an unreasonable amount of time. Users often face a situation where the phone simply refuses to see new headphones or speakers, ignoring connection requests due to a crowded memory buffer.
Cleaning up this list is not just deleting old records, but an important preventive measure to maintain the stability of the radio module. In the shell of MIUI or the new HyperOS, the connection management process has its own features that differ from stock Android. You need to understand the difference between simply breaking the connection and completely removing the device profile from the system database, since only the second option guarantees the reset of potential configuration errors.
In this article, we will take a look at all the ways to clean the list, from standard interface settings to deeper methods through the engineering menu. You will learn how to properly reset Bluetooth settings without losing personal data, and understand why it is sometimes necessary to radically interfere with the operation of the communication module.
Why You Should Remove Old Bluetooth Devices
The accumulation of dozens of profiles in the memory of the smartphone leads to an increase in response time when trying to connect. The operating system is forced to check the access lists and security protocols for each stored gadget, which creates an extra burden on the processor, especially on models with limited RAM, where background services may not work correctly.
Also, older records often contain erroneous encryption keys that can conflict with new connection attempts. If you've ever encountered a situation where headphones are connected but there's no sound, or the connection is cut off after a second, the reason often lies in a littered pairing list, and deleting such records forces the system to shake hands again and generate fresh security tokens.
⚠️ Attention: Removing the device from the list will permanently break the connection with it. Reuse of the gadget will require a pairing procedure again, which may require the accessory to be transferred to search mode.
And privacy is also a consideration, because Bluetooth often has traces of connections to public audio systems in transportation, to other people's speakers at parties, to car taxi tapes. MAC-Addresses and connection history, which in certain situations can be used to track your movements.

Standard Removal Method through MIUI Settings
The safest and most recommended cleaning method is to use a regular system interface, which requires no special knowledge and eliminates the risk of damage to system files. First, you need to go to the main settings menu of your Xiaomi Redmi and select the section responsible for wireless connections.
The sequence is simple, but it requires care, especially if there are many devices, and the list that opens will show all the gadgets that have ever been connected, and the important thing is to distinguish between Connected and Save status, and we're interested in the saved profiles that may be disabled.
To delete a record, you need to click on the gear icon or the arrow to the right of the device name. In the menu that opens, you should find the "Disable" or "Delete" button. Confirm the action, and the system immediately deletes all profile data. If there are many devices, this operation will have to be repeated manually for each of them, since the "Delete All" function is often not on the standard menu.
In some versions of MIUI firmware, the interface may be slightly different, but the logic remains the same. If you don't see the delete button right away, try a long press on the device name - this often causes a context menu with additional options.
Use the Forget Device function to reset errors
Forget Device is key to cleaning up, and unlike a simple disconnect, it removes all pairing keys, codec settings, and A2DP or HFP profiles associated with a particular gadget from the phone’s memory, especially when the device is behaving incorrectly.
This function should be used in the following cases:
- 📱 The device appears in the list but does not connect, giving a pairing error.
- 🎧 Headphones work only in mono mode or with low sound quality.
- 🚗 Car radios can't see the phone after a change PIN-machine code.
- ⌚ Smartwatches lose touch with companion app due to protocol conflict.
After performing the command "Forget" is recommended to restart the smartphone, which will allow the Bluetooth Stack services to completely update and start from scratch. Often users ignore the reboot, wondering why the problem was not solved, even though the profile was deleted.
Why can the “forget” button be inactive?
If the button is inactive (gray), it means that the device is currently being actively used by the system process. Try first to turn off Bluetooth completely, then turn it on again, and only then try to remove the device. This can also happen if the device is connected to another active application, such as a voice recorder or player.> Cleaning the cache and data of the Bluetooth service If manual deletion does not help or the list of devices behaves strangely (for example, devices appear by themselves or disappear), you need to clear the Bluetooth service system cache. This is a deeper procedure that resets the module’s temporary work files without affecting your personal photos or contacts. → Annexes → All applications. In the upper right corner, click on three dots and select "Show system processes». Find the "Bluetooth" (or "Bluetooth MIDI Service", "Bluetooth Share"). Go inside and select "Memory". On the screen that opens, you'll see two important buttons: "Clear Cache" and "Clear Everything" (or "Reset"). It's recommended to use cache cleanup first. If the problem persists, apply a full application data reset. After that, all the stored devices will be deleted automatically, and the module restarts. When you apply Delete only the profile of the gadget again, the service will have to reset the data from the data, you need to reset the data from the data, the service from the data, you will have to the data from the data to the data, the service to clean the data from the data, you will have to the data reset, you need to the data from the data, you will have to clean the data from the data from the data from the data, the data from the service to the data, you will have to understand the data from the data, the data from the data, the data from the data to This takes time, but is often the only way to solve the problem when the phone "does not see" new devices. Radical method: Network Settings Reset When none of the above methods work, network settings reset function comes to the rescue. This is a comprehensive measure that returns all wireless module parameters (Wi-Fi, mobile Internet, Bluetooth) to factory values. This is not a complete phone reset, your applications and files will remain in place. You can find this option in Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. The system will warn you that all saved files will be deleted by the Bluetooth configurations, these deep conflicts could effectively eliminate the action of the files. ⚠️ Note: Before resetting your network settings, make sure you remember passwords from important Wi-Fi networks, as it will be impossible to recover them from the system after reset. Once reset is done, the phone will automatically restart the radio modules. There will be no records left in the Bluetooth list. It's a blank slate from which to start over, and it's often a step that helps when the phone stops seeing devices with the new Bluetooth protocol. 5.0/5.2 After cleaning the list completely, users may find that some devices do not want to connect the first time, which is normal, since there is a process of re-authorization. However, if problems persist, it’s worth checking Bluetooth versions on mated devices. A frequent problem on Xiaomi is an aggressive power saving system that can block Bluetooth background processes. Go to the battery settings and make sure there is no background activity limit set for Bluetooth system services. It is also worth checking the permissions in the section "Application Manager" if the phone stopped seeing any devices at all after cleaning: 🔄 Perform a full smartphone reboot (turn off and on). 📡 Make sure there are no active Bluetooth exceptions left in flight mode. 🔋 Check the battery charge as it is low (< 10%) the system may limit the operation of radio modules. 💡Cleaning the Bluetooth list and resetting the service is a way to fix 90% of connection problems caused by software conflicts and the accumulation of bugs in the system. MIUI. To keep your Xiaomi Redmi healthy, it is recommended to do a preventive Bluetooth list cleaning every few months, especially if you are actively using public spaces or changing cars frequently. Don't store devices you haven't used in more than six months, pay attention to pairing requests, and never accept connection requests from unknown devices in public. Attackers can exploit Bluetooth vulnerabilities to gain access to data or send spam. By clearing the list, you also get rid of potentially compromised access keys. Regular system updates are another important aspect. MIUI HyperOS and Bluetooth Stack Vulnerabilities Frequently Fixed. Check the updates in About Phone to make sure your connection is secure.
