How to Fix Bluetooth Not Working on iPhone (iOS)

Resolve pairing failures, connection drops, and missing Bluetooth toggle.

Last verified: February 21, 2026

iPhone Bluetooth issues are almost always resolved by the forget-and-repair cycle, since iOS stores more connection profile data per device than most platforms and old profiles can conflict with firmware updates on the accessory side. Going to Settings > Bluetooth, tapping the blue i icon next to the problematic device, and selecting Forget This Device forces a completely clean pairing session. If issues persist across multiple accessories, Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings also clears Bluetooth configuration alongside Wi-Fi, which is worth doing if Bluetooth became unreliable after an iOS update.

Quick Steps

Follow in order for the fastest result.

  1. 1Turn Bluetooth off and on from Quick Settings and wait 10 seconds.
  2. 2Put the accessory into fresh pairing mode — typically hold the pairing button until the LED flashes rapidly.
  3. 3Go to Settings > Bluetooth, tap the i next to the device, tap Forget This Device, then pair again.

Frequently Asked Questions

Why won't my iPhone (iOS) find my Bluetooth device?
Ensure the accessory is in active pairing mode — not just powered on. Most accessories only broadcast for 30–60 seconds, then stop advertising. Hold the pairing button until the LED flashes rapidly to re-enter pairing mode. Stay within 1 metre of the device during pairing.
Why does Bluetooth keep disconnecting on iPhone (iOS)?
Common causes: distance (Bluetooth range is typically 10 metres but walls and interference reduce it), low battery on the accessory, or outdated drivers. Keep the accessory charged above 20% and stay within clear line-of-sight range. On Windows, update Bluetooth drivers via Device Manager.
Why is my Bluetooth audio cutting out on iPhone (iOS)?
Bluetooth audio interference is most often caused by 2.4 GHz Wi-Fi congestion, microwave ovens, or metal objects between the devices. Move away from the router, or switch your Wi-Fi to 5 GHz. Also check that no other Bluetooth device is simultaneously connected and competing for bandwidth.
Where is the Bluetooth toggle on iPhone (iOS)?
Swipe down to open Control Center and tap the Bluetooth icon. The full settings are at Settings > Bluetooth.
