How to Reset Bluetooth Settings on Xiaomi Phone: The Complete Guide

Bluetooth on Xiaomi smartphones is one of the most capricious modules, which often starts to glittle after MIUI updates or prolonged use. The problems are different, from the inability to connect to headphones to the constant interruption of communication with smart watches. In 90% of cases, a simple reset of the module helps, but few people know how to do it correctly without losing important data.

In this article, we’ll break down three official Bluetooth reset methods (including the developer’s hidden settings), explain why the module might not work properly after upgrading to MIUI 14/15, and give a checklist for hardware problems. The instructions are relevant for all modern models, from the budget Redmi Note 12 to the flagship Xiaomi 14 Ultra. If you’ve already tried to reboot your phone and reconnect devices, this guide is for you.

When you need to reset Bluetooth on Xiaomi

Before you reset, make sure the problem is really in the Bluetooth module, not the connected device.

• 🔴 The phone does not find headphones/columns, although they are on and charged.
• 🔄 The connection is made, but the sound is interrupted every time. 5-10 seconds
• 📱 The list of available devices displays “ghost” gadgets that have not been used for a long time
• 🔊 The sound only goes through the phone's speaker, although the headphones are connected
• ⚡ After updating MIUI Bluetooth has stopped working at all (the icon of gray color)

If at least one of these points is familiar, resetting is likely to solve the problem, but there are exceptions: for example, Xiaomi models with a Snapdragon 8 Gen 2 chip (for example, Xiaomi 13T) may need to flash the module through Fastboot after reset, which we will discuss in the section on hardware malfunctions.

⚠️ Note: If Bluetooth is not turned on at all (the switchboard is inactive in the settings), the problem may be damage to the antenna or controller.

Method 1: Reset via standard MIUI settings

The simplest and safest method, which works on all versions of MIUI 12 to 15, is suitable for most users, as it does not require developer rights or special knowledge.

Instructions:

1. Open Settings → Connections and Sharing → Bluetooth
2. Slip on the three dots in the top right corner and select Bluetooth Settings.
3. Scroll down and click Reset Settings (or Clear Cache on older versions of MIUI)
4. Confirm the action, wait for the module to restart (usually takes 10-15 seconds)

Once you reset, all the paired devices will be removed and you'll have to reconnect them, which is normal, and it should be, and if you have problems after that, you can move on to the second method.

Method 2: Clearing cache and data through "Applications"

Sometimes a crash occurs due to a damaged cache of the system application com.android.bluetooth, which is deeper than a standard reset, and helps in cases where Bluetooth is turned on but is unstable.

Step-by-step:

1. Go to Settings → Applications → Application Management
2. Slip on three points in the corner and select Show all processes
3. Find Bluetooth (or Bluetooth Share on some models)
4. Open the application page and consistently click: 🧹 Clear the cache 🗑️ Clear the data (this will delete all paired devices!) 🔄 Stop (if the button is active)

Reboot the phone.

⚠️ Note: On some models (e.g, POCO F5) After cleaning the data, Bluetooth may not turn on until the first reboot.

Method 3: Reset via developer settings (for experienced)

If the first two methods didn't work, you'll have to use the hidden settings of the developer mode, which is more radical and can affect other wireless modules (Wi-Fi, NFC), so only use it as a last resort.

How to turn on the developer mode and reset Bluetooth:

1. Activate Developer Mode: Go to Settings → About Phone 7 times tap on MIUI before the message “You became a developer” appears
2. Return to the main settings and open Additional settings → Developer settings
3. Find the Network section and select: Reset your Wi-Fi, mobile network and Bluetooth settings (on MIUI 14+) or Reset your Bluetooth adapter (on older versions)

Confirm the reset and wait for the reset

After that, not only will the Bluetooth settings be reset, but all the stored Wi-Fi networks, as well as some of the mobile Internet settings, and write down or take photos of important passwords before the procedure.

Frequent errors in Bluetooth resetting and how to avoid them

Many users make critical mistakes that not only don’t solve the problem, but make it worse. Here’s what you can’t do when you reset Bluetooth to Xiaomi:

• 🚫 Remove the system application Bluetooth through root access – this will lead to complete inoperability of the module
• 🚫 Resetting your phone to factory settings just because of Bluetooth issues (this is an extreme measure)
• 🚫 Use Play Market “optimizers” – they often damage system files
• 🚫 Disable Bluetooth via Task Manager – This can cause conflicts with the MIUI

Also a common mistake is not to check device compatibility. For example, AirPods Pro 2 headphones may not work smoothly with Redmi 9A due to different versions of Bluetooth protocol (5.3 vs 5.0). Before reset, make sure that your device supports the protocol of the connected equipment.

💡

If Bluetooth still doesn’t work with a particular device after reset (like a smartwatch), try connecting it to another phone. If the problem recurs, the device itself is faulty, not the module in Xiaomi.

Hardware problems: when resetting will not help

If you've tried all the reset methods, but Bluetooth still doesn't work, the problem could be physical damage to the module.

• 🔌 Bluetooth does not turn on at all (tumbler in the settings is inactive)
• 📡 The phone does not find any device, although other phones can see them"
• 🔥 The module is very hot when you try to activate
• 🛠️ The problem arose after falling or getting moisture

On Xiaomi models with a separate Bluetooth chip (such as the Redmi Note 11 Pro+ 5G), the fault can be due to the antenna rolling off or damage to the tracks on the board, in which case only repairs at the service center will help.

⚠️ Attention: On water-protected phones (IP53/IP68) Bluetooth problems are often caused by corrosion of the antenna contacts. If the phone has been in water, don't try to dry it with a hair dryer, it will speed up oxidation.
