Resetting Bluetooth settings on Xiaomi smartphones can be required in a variety of situations, from trivial problems with the connection of headphones to serious failures in the module. For example, if your Redmi Note 12 or POCO X5 stopped seeing previously coupled devices, constantly breaks the connection to the speaker or gives an error βfailed to connectβ β the first thing to clean up all the stored Bluetooth data. Unlike a complete reset of the phone, this procedure will take no more than a minute, but will save 90% of typical problems.
In this article, we will discuss three ways to remove Bluetooth settings: through the standard MIUI menu, using hidden developer settings, and even a complete module reset (if software methods did not work), separately discuss the nuances for different versions of the firmware, from MIUI 12 to MIUI 14, and also explain how to avoid typical errors when pairing devices again. If after reading you have questions, check the FAQ section at the end of the article, where we have collected answers to the most common problems.
Why you should delete Bluetooth settings on Xiaomi
The Bluetooth module in Xiaomi smartphones accumulates digital garbage over time: cache of associated devices, temporary profile files (for example, A2DP for sound or HFP for hands-free), as well as data on previous connections.
- π The device does not connect - the smartphone "sees" headphones or a column, but when you try to connect it gives an error.
- π A ragged sound or stuttering is especially relevant for TWS-Headphones (e.g. Redmi Buds 4 or Xiaomi AirDots).
- π Automatic connection to the wrong device β the phone clings to the old speaker instead of new headphones.
- β οΈ Failures after update MIUI β frequent problem when switching to a new firmware version (for example, with MIUI 13 on MIUI 14).
Before you rush to reset your settings, check the basics:
β οΈ Note: If the problem only manifests itself with one device (e.g., Xiaomi Buds headphones) 3T They don't plug in, they plug in. JBL It works fine, and you can try resetting this particular gadget first, and it's often the device that's the problem, not the smartphone.
Also make sure that:
- πΆ Headphones / column are charged and are in pairing mode.
- π± Bluetooth enabled on your smartphone (check notification panel or Settings) β Bluetooth).
- π You rebooted your phone after the last update. MIUI.
Method 1: Remove individual devices via Bluetooth menu
The easiest and safest method is to remove unnecessary devices manually.This won't reset all the module settings, but will clear the data of specific gadgets that are causing problems.The instruction is relevant for all Xiaomi, Redmi and POCO smartphones on MIUI 12/13/14.
Steps:
- Open the settings (cog icon on the desktop).
- Go to Connections and Sharing β Bluetooth.
- Push the gear. βοΈ Next to the name of the problem device (e.g. Mi Smart Band 7 or Redmi Buds 4).
- In the menu that opens, select Delete (or Forget the device in some firmware versions).
- Confirm the action by pressing OK.
If the device does not appear in the list, but previously was connected:
- π Try turning it on and switching it to pairing mode (usually by pressing the power button for 5-10 seconds).
- π Reboot your smartphone β sometimes it helps to βupdateβ the list of devices.
βοΈ Preparing for Bluetooth reset
Important: Once the device is removed, it will have to be paired again. Some gadgets (such as the Xiaomi Mi Band) may need to be reconfigured in the Mi Fit or Zepp Life app.
Method 2: Completely reset Bluetooth settings via the All Settings menu
If deleting individual devices didnβt work, or if you want to clear all Bluetooth data (including cache and system files) completely, use the hidden reset feature, which is more radical, but effective in case of serious crashes.
Instructions:
- Open the Settings. β The phone.
- Find All Features (or MIUI Version) and click on it 5-7 times in a row until the notification βYou are a developer!β appears.

If the reset point of the network settings is not:
- π§ Check if the developer mode is on (see step 2).
- π± In some models (for example, POCO F5) This item may be called Resetting Network Settings.
- π Try to update the firmware - in the old versions MIUI (below 12.5) this paragraph may not be available.
On smartphones with MIUI 14 and later, the Bluetooth reset can be made to a separate menu. Check Settings β Connections and Sharing β Additional β Reset Bluetooth settings.
Method 3: Reset via engineering menu (for power users)
If standard methods have failed and Bluetooth problems remain (e.g., the module doesnβt turn on at all or shuts down permanently), you can try a hard reset via the engineering menu, which requires caution, as improper actions can disrupt other functions of the phone.
Instructions:
- Open the phone app and enter the combination: ##4636##
- In the menu that opens, select Phone Information (or Phone Information).
