How to Quickly Fix iPhone Not Connecting to Bluetooth in iOS 11

If your iPhone can't connect to Bluetooth in iOS 11, the issue might be system-related. You can try resolving it yourself using this simple troubleshooting guide.

1. Disable and Enable Bluetooth

Go to “Settings” > “Bluetooth,” and then turn Bluetooth off. Wait a few seconds, and then turn Bluetooth back on. Or, swipe up from the bottom of your screen to access the Control Center, and toggle Bluetooth off and on again there.

2. Turn Wi-Fi on or off

Go to “Settings” > “Wi-Fi” and turn it off. Wait a few seconds, and then reconnect to your Wi-Fi network.

3. Turn on/off Flight mode

Go to Settings > Airplane Mode, and turn it on. Wait a few seconds, then turn it off.

4. Restart your iPhone

Press and hold the Sleep/Wake button, then slide "Slide to Power Off" to turn off your iPhone. Wait 30 seconds, then press and hold the Sleep/Wake button again until you see the Apple logo. This can fix many small iOS 11 issues, such as non-working notifications, alarms, or live wallpapers.

5. Perform a force restart on your iPhone

If a normal restart doesn't work, you can force your iPhone to restart by holding down the Sleep/Wake button and the Home button at the same time. Hold both buttons for at least 20 seconds, until you see the Apple logo. If you have an iPhone 8 or iPhone X, learn how to force restart your iPhone 8/iPhone X instead.

6. Reset Network Settings

Go to “Settings” > “General” > “Reset” > “Reset Network Settings.” This may take a few seconds to complete, but can resolve many network-related issues, such as GPS not working in iOS 11 or Wi-Fi not working.

Update to the latest version of iOS

If your iPhone can't connect to Bluetooth because of an iOS bug, you can fix this by updating your iPhone to the latest version of iOS, since fewer bugs that affect normal use will be present.

Go to “Settings” > “General” > “Software Update” and check if there's a new version available. If there is, tap “Download and Install” to begin installing the latest version of iOS 11 on your iPhone.

8. Reset all settings/Wipe all content and settings

Resetting all settings restores all settings to their default values, but does not delete any data from your device.

Go to Settings > General > Reset > Erase All Content and Settings.

Tip

If Reset All Settings doesn't help, you can refer to Erase All Content and Settings. This will restore your iPhone to its factory state and remove files, apps, and data from your iPhone. So, back up your iPhone with a free iPhone data transfer tool other than iTunes or iCloud before erasing it. And MobiMover is such a program that can help you transfer contacts, messages, notes, calendars, voicemail, books, Safari bookmarks and history, photos, videos, and audios from iPhone to a Windows computer with one click.

Step 1: Connect your iPhone to the computer and trust the computer. Launch MobiMover and choose Backup Manager > Backup.

Step 2: Since all supported file types are selected by default, you can simply click on "One-Click Backup" to start backing up your iPhone to the computer.

Step 3: Wait for the backup to complete. To restore a backup, go to Backup Manager > Restore, and follow the on-screen instructions.

Restore your iPhone with iTunes
