Removing Bluetooth device on Xiaomi Redmi Note smartphones seems like a simple task – until you encounter bugs MIUI, When the gadget gets stuck in the list of mates, and reconnection is impossible, 80% of the time the problem is not in the device itself (earphones, speakers or fitness bracelet), but in the cache of the Bluetooth module or firmware failures. This article covers all current removal methods, from standard to hidden, including: ADB-Teams for experienced users.
We tested the instructions on the Redmi Note 8 Pro (MIUI 14), Redmi Note 10 (MIUI 13) and Redmi Note 12 Pro+ (HyperOS) — the interface differences are minimal, but they are. If your model is older than 2019, look at the section on resetting Bluetooth settings: older versions of MIUI 11-12 often require manual cache cleaning. Also, the article breaks down typical errors like “failed to delete the device” or “Device is not responding” — with specific solutions for each.
1. Standard removal via Bluetooth settings
The most obvious way is to use the built-in Bluetooth menu in the settings. It works on all versions of the Redmi Note, but can crash if the device was connected via Xiaomi’s MIUI Optimized Connection, in which case, after removal, the gadget may reappear in the list in a few minutes.
To avoid this, follow the algorithm:
- Open Settings → Connections and Sharing → Bluetooth.
- Find the desired device in the list of “Conjugated devices” and tap the gear (⚙️) near-name.
- Choose Delete (or Disable if the Delete option is inactive).
- Important: Do not turn on Bluetooth for 30 seconds after removal, as this will prevent automatic reconnection.
If the Remove button is inactive (in gray), it means the device is currently connected. First, turn it off, then try again. 11/12 HyperOS may require additional confirmation via biometrics (print or print). PIN-code).

2. Delete via "All Settings" (hidden MIUI section)
MIUI 12-14 and HyperOS have a hidden All Settings section where you can manage devices that don't appear in the main Bluetooth menu.This is true for the Redmi Note 9/10, where sometimes gadgets get stuck after an incorrect shutdown.
Instructions:
- Open Settings and in the search bar (magnifying glass at the top) enter All settings.
- Select Connected Devices → Bluetooth.
- In the list, find the problem device, tap it and select Forget (in English firmware - Forget).
This method often helps when standard removal fails due to a MIUI Optimized Connection bug. If the device still appears after a reboot, move on to the next method.

3. Quick removal through the notification panel
On the Redmi Note 8/9/10 with MIUI 11-13, you can remove the device directly from the notification panel — this saves time, but does not work with all gadgets.
How to do this:
- Swipe down the screen to open the notification bar.
- Find a notification about the connected device (for example, “Xiaomi Buds are connected”) and tap it.
- In the window that opens, select Disable, then Delete (or Forget the device).
If the notification does not appear, then the device is connected in the background. Try to turn Bluetooth on/off or play the sound through the speaker of the gadget (for example, run music on the speaker).

4. Reset Bluetooth settings (cache cleanup)
If the device persists in not removing or if errors like “failed to connect” occur after re-pairing, the problem lies in the cache of the Bluetooth module. On the Redmi Note with MIUI, this cache does not clear automatically, which leads to conflicts with new connections.
To reset the settings:
- Open Settings → Applications → Application Management.
- In the search bar, type Bluetooth and select “Bluetooth Settings” (not to be confused with the Bluetooth app itself!).
- Click Warehouse → Clear the cache and Clear the data.
- Reboot your smartphone.
After reset, all the connected devices will be removed and the Bluetooth settings will return to factory settings, a method recommended if you plan to connect new gadgets or encounter system errors (for example, error code 133 when connecting).
💡
If Bluetooth stopped turning on after reset, restart your smartphone in Safe Mode (hold the shutdown button → “Reboot Safe Mode”). This will help determine whether a third-party app is to blame for the problem.
5. Removal via ADB (for power users)
If standard methods don’t work, you can remove the device via Android Debug Bridge (ADB), which requires connecting the smartphone to a PC, but is guaranteed to clear all traces of the gadget from the system, including hidden MIUI files.
Instructions:
- Install ADB Tools on your PC and enable USB Debugging on your smartphone (Settings → About Phone → MIUI Version → 7 times tap the build number → Return to Additional Settings → For Developers → Debugging by USB).
- Connect Redmi Note to your PC and type in the command line:
adb devices(Your device should appear)
adb shell pm clear com.android.bluetooth(clears the cache and Bluetooth data)
adb shell settings delete global bluetooth_devices(Remove all stored devices)
If you need to remove a particular device, get it first. MAC-address:
adb shell settings get global bluetooth_devicesThen remove it by MAC:
adb shell settings delete global bluetooth_devices <MAC- address >This method is useful if the device is “ghostly” hanging in the system, but does not appear in the settings, for example, this is often the case with Mi Band or Xiaomi Smart Home gadgets after resetting their settings.
💡
ADB-commands are the only way to remove devices added through MIUI Optimized Connection or system applications like Mi Home, which standard methods don't see.
6. Solving typical errors in removal
Even after removing the device, Redmi Note users are facing problems, and here are the most common errors and solutions:
| Mistake. | Reason. | Decision |
|---|---|---|
| Failed to remove device | The device is connected in the background (for example, via Mi Fit or Spotify) | Close all applications using Bluetooth through Settings → Applications → Launched |
| The device is not responding. | Failure in the operation of the Bluetooth module or firmware | Reset your Bluetooth settings (Section 4) or update your MIUI |
| The device is returned after removal | MIUI Optimized Connection or Cache Not Cleared | Use ADB (Section 5) or disable optimization in Settings → Special Features → Simplified Mode |
| Error code 133 when connecting | Bluetooth profile conflict (e.g. A2DP and HFP) | Remove the device, reset Bluetooth settings and reconnect in pairing mode (hold the button on the gadget 5-10 seconds) |
If none of the methods worked, check if the antivirus connection (such as Avast or 360 Security) is blocked. On the Redmi Note with HyperOS, the Privacy → Permissions → Bluetooth function can also interfere - make sure that the applications have access to the module.
💡
Redmi Note 12 with HyperOS has a new Bluetooth Auto-Connect feature that automatically connects devices within range. To turn it off, go to Settings → Connections → Bluetooth → Additional → Auto Connection and deactivate the slider.

- 📱 Redmi Note 9/10 (MIUI 12-13): There is an option to Delete in the notification bar, but sometimes devices get stuck because of the MIUI Optimized Connection. solved by Bluetooth reset.
Redmi Note 7 and older (2019 and earlier) may not have the option to Clear the Bluetooth cache, in which case only a complete network reset (Settings → System → Reset → Network Settings Reset) will help, but this will remove all stored Wi-Fi and mobile settings.
💡
On the Redmi Note 10 Pro and newer with the Snapdragon 7xx/8xx, the Bluetooth module is integrated into the chipset, so crashes are often solved by a firmware update. Check the relevance of MIUI in Settings → About Phone → System Update.
8. Alternative methods (if nothing helps)
If the device is not removed, radical measures remain:
- 🔄 Reset to factory settings: Delete all data but guaranteed to clear the Bluetooth list. pre-reverse through Settings → The phone. → Backup.
