Troubleshooting an iPhone Bluetooth Connection


All generations of the Apple iPhone include Bluetooth connectivity, allowing users to connect wirelessly and securely to headsets and other Bluetooth-enabled devices. Occasionally, an iPhone and a Bluetooth device may have trouble recognizing each other to initiate a connection or may have trouble maintaining a connection. Troubleshooting an iPhone Bluetooth connection starts with diagnosing what the trouble is and where it originates from, after which you can choose the best path to resolve your issue.

  • Verify that Bluetooth has been enabled on your iPhone. Check the top right-hand corner of your iPhone. If there is no Bluetooth symbol next to the battery indicator, the Bluetooth functionality on your iPhone has not been enabled. To enable Bluetooth, navigate to "Settings" on your iPhone, and then choose the "General" menu. Choose "Bluetooth" and tap to turn it "On." The Bluetooth indicator should now show up next to the battery. The iPhone should now be discoverable and previously paired devices should show up in the Bluetooth menu.

  • Verify that the Bluetooth device that you want to use with your iPhone is charged, turned on, and set to "Discoverable." The various indicators and processes for this will vary depending on the device. Consult your Bluetooth device's manual for more direction.

  • Pair the Bluetooth device with another compatible device other than your iPhone, if possible. If you have verified that your iPhone's Bluetooth is enabled and that your other device is charged and turned on but you are unable to see it in your iPhone's listing, try pairing it with another Bluetooth-enabled device. This will help you determine whether the pairing issue is with the device or your iPhone.

  • Verify that your iPhone is not already paired with another device. If your iPhone is not autopairing with a device in its memory, the problem could be that the iPhone is currently paired with another device. Look on the iPhone screen to see if the Bluetooth icon in the upper-right corner is on and shaded blue. If so, this indicates that your iPhone is already connected to another device. Turn off or manually unpair the current Bluetooth-connected device. Once the first device has been disconnected, the device that is set to autopair should automatically find and connect itself to your iPhone.

  • Check the area for possible radio interference. If you are able to successfully pair and connect your Bluetooth device but the connection seems to be intermittent, radio interference may be disrupting the connection. Improperly shielded electronic equipment of any type may produce interference. If you suspect that your Bluetooth connection is being affected by interference, move to an area that does not contain objects that may interfere with the signal. Common sources of interference include vehicles, older electronics and medical devices including pacemakers and hearing aids.
