How to remove Bluetooth device on Xiaomi Redmi smartphones: all ways and solutions of errors

Faced with a problem when Xiaomi Redmi stubbornly does not want to “forget” a Bluetooth-connected headset, speaker or fitness bracelet? or the device connects automatically, interfering with other gadgets? In this article, you will find 3 proven ways to remove Bluetooth devices — from the standard settings menu to hidden MIUI functions. We will also examine why a smartphone may not see the “Delete” button, how to reset Bluetooth settings to factory ones and what to do if the device appears on the list again after a reboot.

The feature of MIUI firmware (even in the latest versions based on Android 13/14) is aggressive caching of connected gadgets. This means that simply pressing “Disable” does not always solve the problem – the smartphone can automatically restore connection the next time Bluetooth is turned on. Our instructions are relevant for all Redmi models (from Redmi Note 4 to Redmi Note 13 Pro+), as well as for the POCO and Mi lines based on MIUI.

Before you start deleting, make sure that the problem is not related to the device that is connected to it. TWS-Headphones (such as Redmi Buds 4 or Xiaomi AirDots) can automatically reconnect due to the Fast Pair feature in Android. In this case, additional configuration will be required - read about this in the section on hidden settings.

Method 1: Standard removal via Bluetooth menu

The most obvious method is to use the built-in MIUI settings, which is suitable for most devices, but may not work if:

• 🔄 The device was connected through MIUI Quick Share (formerly Mi Share).
• 🔒 Bluetooth Gadget Protected PIN-code or require confirmation on the device itself (e.g., Xiaomi Smart Band 8).
• 📱 The smartphone runs on custom firmware (for example, Pixel Experience or LineageOS).

To remove the device in a standard way:

1. Open the settings (cog icon on the desktop).
2. Go to Connections and Sharing → Bluetooth.
3. Click on the name of the device you want to remove (e.g. Redmi Buds 3 Lite).
4. In the window that opens, tap the basket icon (or the “Delete” / “Forget the device” button).

Table: Common mistakes and their solutions

What if the device is not removed even after resetting?

In 1% of cases (usually on smartphones with custom firmware or after a failed update), a Bluetooth device can get stuck at the kernel level.

1. Fastboot Flashing (complete cleaning of all partitions, including persist)
2. Manual editing of the file /data/misc/bluedroid/bt_config.conf (requires root rights).
3. Contact the service center (if the problem is hardware – for example, a Bluetooth module is damaged).

For flashing through Fastboot:

1. Download the official firmware for your model from the Xiaomi Firmware website.
2. Unpack the archive and launch the script flash_all.bat (Windows or flash_all.sh (Linux/Mac).

2. Select Phone Information → Bluetooth.
3. Click Enable and wait for the module to initialize.
