How to Fix Bluetooth Not Working or Pairing Issues on Xiaomi

Xiaomi Bluetooth issues typically fall into a few categories: not discovering devices, pairing failure, or frequent disconnects. Here are the solutions.

Fix 1 – Toggle Bluetooth Off and On

1. Swipe down → tap Bluetooth to turn off.
2. Wait 10 seconds → tap again to enable.
3. Try pairing again.

Fix 2 – Forget and Re-Pair the Device

1. Settings → Bluetooth → [device name] → Unpair / Forget.
2. On the Bluetooth device, reset or clear pairings.
3. Put device back in pairing mode → re-pair from your Xiaomi.

Fix 3 – Clear Bluetooth Cache

1. Settings → Apps → Manage apps → All apps → search "Bluetooth".
2. Tap Bluetooth system app → Clear data → Clear cache.
3. Restart the phone.

Fix 4 – Toggle Airplane Mode

Airplane mode resets all radios simultaneously:
1. Enable Airplane Mode for 30 seconds.
2. Disable → then manually turn Bluetooth back on.

Fix 5 – Remove Bluetooth Devices Limit

On some MIUI/HyperOS builds, too many paired devices cause issues:
1. Go to Settings → Bluetooth → Paired devices.
2. Remove old/unused paired devices until fewer than 10 remain.

Fix 6 – Check for HyperOS / MIUI Update

1. Settings → About Phone → MIUI/HyperOS version → Check for updates.
2. Bluetooth bugs are often fixed in point releases — update if available.

Fix 7 – Disable Battery Optimization for Bluetooth App

1. Settings → Battery & Performance → Battery → App battery saver.
2. Find Bluetooth → set to No restrictions.

Fix 8 – Reset Network Settings

1. Settings → Additional Settings → Backup & Reset → Reset Wi-Fi, Mobile & Bluetooth Settings.
2. This clears all Bluetooth pairings and resets the Bluetooth stack.

Disconnect vs. Pairing Failure

Pro Tips

• Keep Bluetooth devices within 10 meters and away from microwaves / Wi-Fi routers operating on 2.4GHz.
• On HyperOS, the Sound quality setting (HD audio / SBC / AAC / LDAC) can be found by long-pressing a paired audio device in Bluetooth settings.
