How to Fix iPhone 7 Plus Bluetooth Keeps Disconnecting Issue

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:

  1. Connect your iPhone to a computer with iTunes open.
  2. Press and hold the Power and Volume Down buttons for 8 seconds.
  3. Release the Power button but keep holding Volume Down until iTunes detects a device in Recovery Mode.
  4. 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.
