Steps to Unpair Your Apple Watch from the Old iPhone

Unpairing your Apple Watch from the old iPhone is a crucial step to ensure the device is properly disconnected and ready to be paired with a new phone. This process also creates a backup of your Apple Watch data on the old iPhone, allowing a smooth transition later.

To unpair your Apple Watch, follow these steps:

  • Keep your Apple Watch and old iPhone close together during the process.
  • Open the Watch app on your old iPhone.
  • Navigate to the My Watch tab and select your watch at the top of the screen.
  • Tap the i icon next to the watch you want to unpair.
  • Choose Unpair Apple Watch.
  • Confirm the unpairing by tapping again and, if applicable, enter your Apple ID password to disable Activation Lock.

The unpairing process can take several minutes as the watch creates a final backup and erases its content and settings. Once complete, your Apple Watch will be reset to factory settings, ready for pairing with a new iPhone.

Manually Erasing Your Apple Watch

If you no longer have access to the old iPhone, you can erase your Apple Watch directly from the device to disconnect it. This method will remove all content and settings but does not remove the Activation Lock, which requires your Apple ID credentials.

To manually erase your Apple Watch:

  • On the Apple Watch, open the **Settings** app.
  • Tap **General** > Reset.
  • Select Erase All Content and Settings.
  • If prompted, enter your passcode.
  • Confirm the action and wait for the device to reset.

After the reset, Activation Lock remains active, so ensure you know your Apple ID and password before erasing the watch to avoid being locked out.

Disabling Activation Lock on Your Apple Watch

Activation Lock is a security feature that ties your Apple Watch to your Apple ID, preventing unauthorized use if lost or stolen. When disconnecting from an old phone, disabling Activation Lock is essential to allow pairing with a new device.

Activation Lock automatically disables when you unpair the watch using the Watch app on your old iPhone. However, if you erased the watch manually or no longer have the old iPhone, you must remove the device from your Apple ID account to disable Activation Lock.

To remove your Apple Watch from your Apple ID:

  • Go to [appleid.apple.com](https://appleid.apple.com) and sign in.
  • Under Devices, select your Apple Watch.
  • Click Remove from account.
  • Confirm your choice.

This step ensures the watch is no longer linked to your Apple ID and can be set up with another iPhone.

Below is a table summarizing the key features of each method for disconnecting your Apple Watch from an old phone:

Method Requires Old iPhone Preserves Backup Disables Activation Lock Recommended For
Unpair via Watch App Yes Yes Yes Smooth transition to new iPhone

Additional Tips for a Smooth Transition

  • Before unpairing, ensure your old iPhone is updated to the latest iOS version to avoid compatibility issues.
  • Backup your iPhone to iCloud or a computer to secure your Apple Watch data.
  • After unpairing, verify that your Apple Watch is no longer listed under your Apple ID devices.
  • When setting up your Apple Watch with a new iPhone, restore from the latest backup if available to retain your settings and data.

Additional Considerations for Cellular Plans

If your Apple Watch is equipped with cellular connectivity, managing your cellular plan during the unpairing process is crucial to avoid unexpected charges or service interruptions.

  • Removing Cellular Plan: If you will no longer use the watch with cellular, removing the plan during unpairing cancels the subscription with your carrier.
  • Transferring Cellular Plan: If you plan to pair the watch with a new iPhone, choose to keep the cellular plan so it can be transferred seamlessly.
  • Contact Carrier: In cases where the cellular plan does not transfer automatically, contact your carrier for assistance in deactivating or moving the plan.
