Why You Need to Re-Pair Your Apple Watch to a New iPhone
When you upgrade your iPhone, your Apple Watch doesn’t automatically connect to the new device. Because the Apple Watch is deeply linked to iOS features like iCloud, Health, and Messages, re-pairing is essential for:
- Restoring fitness data and activity history
- Maintaining watchOS settings and complications
- Ensuring proper notification delivery
- Reconnecting apps and Apple Pay settings
Backup First: What You Need Before Pairing
Before jumping into the steps, here’s what you should have ready:
Checklist Before You Begin
- Both your old iPhone and new iPhone
- Apple Watch charger nearby (battery at least 50%)
- Wi-Fi and Bluetooth enabled on both phones
- Your Apple ID and password
Apple Watch backs up automatically when it’s unpaired from the iPhone. So unpairing it from your old phone creates the latest backup.
How to Pair Apple Watch to New Phone [With Backup]
If you still have access to your old iPhone, this is the easiest and safest method.
Step 1: Back Up Your Old iPhone

- Go to Settings > [your name] > iCloud > iCloud Backup
- Tap Back Up Now
Or use iTunes/Finder on a Mac or PC if you prefer a local backup. This backup includes Apple Watch data.
Step 2: Set Up Your New iPhone

- Turn on the new iPhone and restore it from your iCloud or iTunes backup.
- Use the same Apple ID.
- Keep the Apple Watch nearby during this process.
Step 3: Re-Pair Apple Watch Automatically
After the new iPhone setup:
- Keep Apple Watch near your new iPhone.
- A message should appear: “Use your Apple Watch with this iPhone?”
- Tap Continue.
- Follow on-screen steps to complete the pairing.
- Select Restore from Backup when prompted.
Your Apple Watch will now sync your previous settings, apps, and health data.
How to Pair Apple Watch to New Phone Without Old Phone
