The iPhone 7 Plus brought a lot of upgrades — but Bluetooth issues are something a lot of users still run into. If your iPhone 7 Plus keeps disconnecting from Bluetooth accessories like headsets, car systems, or speakers, you’re not alone. Here’s everything you can try to get a stable Bluetooth connection again.
Why Bluetooth Problems Happen on iPhone 7 Plus
Most Bluetooth issues come down to either:
- Software glitches (on the iPhone or the accessory)
- Proximity issues (too far away or interference)
- Incorrect settings or incomplete pairing
- Hardware damage (especially if your phone was dropped or exposed to liquid)
If Bluetooth was working fine before and started acting up suddenly, a software bug or setting glitch is likely. If you’ve dropped your phone or Bluetooth AND Wi-Fi are both acting up, you might be looking at a hardware antenna problem.
How to Fix iPhone 7 Plus Bluetooth Connection Problems
Try these methods one by one — after each step, reconnect your Bluetooth device to check if the issue is resolved.
Reboot Your iPhone and Bluetooth Device
A simple restart can fix minor Bluetooth glitches.
- Turn off both your iPhone and Bluetooth accessory.
- Wait about 30 seconds, then turn them back on.
Toggle Bluetooth Off and On Again
Turning Bluetooth off and on can reset the wireless connection.
- Go to Settings → Bluetooth and toggle it OFF, then ON again.
- Or swipe up for Control Center and tap the Bluetooth icon off and back on.
- You can even ask Siri: “Turn off Bluetooth”, then “Turn on Bluetooth.”
Turn Pairing Mode Off and Back On
Many Bluetooth devices have a physical button to toggle pairing mode.
- Turn pairing mode off, wait a few seconds, then turn it back on.
- Reconnect the Bluetooth device to your iPhone.
Forget the Bluetooth Device and Re-Pair
Sometimes you need to start from scratch with the connection.
To forget and re-pair a Bluetooth device:
- Go to Settings → Bluetooth.
- Tap the blue (i) next to the device name.
- Tap Forget This Device, then confirm.
- Reboot your iPhone and Bluetooth accessory, then re-pair them.
Reset Network Settings
If the problem seems deeper, reset all network settings — this clears Bluetooth pairings, Wi-Fi passwords, and VPNs.
To reset network settings:
- Go to Settings → General → Reset → Reset Network Settings.
- Enter your passcode if prompted.
Once done, reconnect your Bluetooth device and test again.
Perform a DFU Restore
If Bluetooth is still unstable, a DFU restore (Device Firmware Update) is the deepest type of reset you can do. It wipes everything and reloads the firmware fresh.
How to enter DFU mode:
- Connect your iPhone to a computer with iTunes open.
- Press and hold the Power and Volume Down buttons for 8 seconds.
- Release the Power button but keep holding Volume Down until iTunes detects a device in Recovery Mode.
- Follow the prompts in iTunes to Restore your iPhone.
⚠️ Backup your data first — a DFU restore erases everything!
Other Things You Can Try
- Update to the latest iOS version — software updates often fix Bluetooth bugs.
- Use AirDrop instead if you’re trying to transfer files between Apple devices.
- Contact Apple Support if Bluetooth issues started after a major update — they may have a fix or offer service options.
- Check accessory compatibility — some older Bluetooth devices might not fully support iOS 11+.
If you’re sure the issue is with the Bluetooth accessory, reach out to the device’s manufacturer for firmware updates or troubleshooting tips.
