iPhone Bluetooth not connecting? 8 fixes to try

2 min read · 8 steps · Updated 2 October 2026

Bluetooth problems are usually a stuck connection on one side. Resetting the pairing fixes most of them.

Step by step

1. Switch Bluetooth off and on

   Do it under Settings, Bluetooth. The button in Control Centre only disconnects devices until tomorrow.

   Done

2. Check the accessory

   Make sure it is charged, switched on and close to the phone. Many headphones need to be put in pairing mode again before a new connection.

   Done

3. Disconnect it from other devices

   Headphones and speakers often reconnect to the last laptop, tablet or phone they used. Switch Bluetooth off on that device for a moment.

   Done

4. Restart both devices

   Restart the iPhone and switch the accessory off and on.

   Done

5. Forget the device and pair again

   In Settings, Bluetooth, tap the i next to the accessory and tap Forget This Device. Then pair it as if it were new.

   Done

6. Check the app permission

   Fitness bands, smart home devices and car apps need Bluetooth permission. Open Settings, Privacy & Security, Bluetooth and switch the app on.

   Done

7. Update iOS and the accessory

   Install any iOS update. Many accessories update their own software through the maker's app.

   Done

8. Reset network settings

   Open Settings, General, Transfer or Reset iPhone, Reset, Reset Network Settings. This removes all Bluetooth pairings and saved Wi-Fi passwords.

   Done

Good to know

For a car: delete the phone from the car's own Bluetooth list as well, then pair again while parked.

If the Bluetooth switch is greyed out or spins forever, that suggests a hardware fault. Contact Apple.

In short: Bluetooth off and on, restart both, forget the device and pair again.
