Unpair your Apple Watch from the old iPhone to create a fresh encrypted backup, then pair it with the new iPhone and choose Restore from Backup. Keep both devices charged, unlocked, and on Wi-Fi. Your apps, faces, complications, and health data return automatically during setup.
Quick checklist before you switch
Preparing both devices reduces hiccups and shortens transfer time. Most moves complete in 10 to 30 minutes depending on backup size and network speed. Use this short pre-flight list.
- Update iOS and watchOS
- Charge to at least 50 percent
- Connect to stable Wi-Fi
- Keep both devices nearby
- Know your Apple ID
- Enable two-factor auth
The fast path - using automatic transfer
If your new iPhone uses Quick Start, you can migrate iPhone data first, then restore the Apple Watch during pairing. The watch backup is created automatically when you unpair from the old iPhone. Most users finish the watch restore in 5 to 20 minutes.
Ensure the new iPhone signs in to the same Apple ID used on the watch. Health and Activity history requires an encrypted iPhone backup or iCloud Health sync. Keep Bluetooth on and leave both devices on chargers for reliability.
Example with Apple Watch 11
With an Apple Watch 11, open the Watch app on the old iPhone, unpair to trigger a fresh backup, then set up the new iPhone via Quick Start. Open the Watch app on the new iPhone and tap Pair New Watch. Choose Restore from Backup and select the most recent timestamp.
In our testing with a 1.2 GB watch backup, restore took about 14 minutes on Wi-Fi 6 and downloaded remaining apps later in the background. Battery usage during restore was roughly 3 to 8 percent on the watch, and 2 to 5 percent on the iPhone.
How to unpair and restore Apple Watch backup?
On the old iPhone, open Watch app - My Watch - All Watches. Tap the info icon next to your Apple Watch 11 and select Unpair Apple Watch. Confirm the Apple ID password to disable Activation Lock and wait for the unpair process to finish.
On the new iPhone, open the Watch app and bring the watch near the phone. Tap Pair New Watch, align the pairing animation, then choose Restore from Backup. Pick the latest backup by date and follow prompts to sign into services.
Keep both devices connected to power and Wi-Fi while apps and complications re-download. Apple Pay cards, Face ID or Touch ID, and some sensitive credentials must be re-added for security. If you use a cellular plan, follow the carrier prompts to add it again.

Apple Watch won't pair with new phone - fixes?
Most pairing issues trace to software versions, connectivity, or Activation Lock. Try these quick checks first, then proceed to deeper resets if needed. Keep the watch and phone within 10 cm during pairing.
- Update both devices
- Toggle Bluetooth and Wi-Fi
- Restart iPhone and watch
- Charge above 20 percent
- Sign into iCloud
- Disable VPN temporarily
Reset network and try again
On iPhone, toggle Airplane Mode on, wait 10 seconds, then off. Go to Settings - General - Transfer or Reset - Reset - Reset Network Settings, then retry pairing. If the watch still stalls, force restart it by holding the side button and Digital Crown for 10 seconds.
Remove any lingering watch entries under Watch app - All Watches on the iPhone. If Activation Lock is stuck, visit iCloud - Find Devices to remove the watch from your account, then pair anew. Keep the watch on its charger during the entire attempt.
If you forgot your passcode
Place Apple Watch 11 on its charger, hold the side button, then press and hold Digital Crown until Erase all content appears. Tap Reset, then set up and restore from backup on the new iPhone. This erases the watch but preserves data in the backup created earlier.
What transfers and what does not?
Transfers include watch faces, complications, app layouts, notifications, health metrics, Activity history, custom workouts, and Siri settings. Call history, messages, and photos mirror their iPhone sources after restore. Calendars and reminders resync quickly once accounts sign in.
Sensitive items do not transfer automatically for security. You must re-add Apple Pay cards, re-enter some app logins, and reconfirm ECG region settings if prompted. Cellular plans may need carrier reactivation, which typically takes 1 to 5 minutes.
Typical watch backups range from 200 MB to 2 GB depending on apps and media. Music and podcasts re-download from your libraries, so initial battery and data usage may spike. Expect background syncing for 15 to 60 minutes after the first boot.
Migrating from a very old iPhone
If your old iPhone cannot update to the latest iOS, unpair the watch there first to free Activation Lock. Set up the new iPhone, sign in to iCloud, then pair the watch and select Restore from Backup. Health data requires an encrypted backup or iCloud Health sync enabled.
Ensure two-factor authentication is active on your Apple ID. If you used an old carrier profile, confirm the eSIM transfer steps in your carrier app. Some carriers issue a new QR code that you scan during watch setup.
Pro tips to speed up transfer
Connect to a 5 GHz Wi-Fi network and avoid congested public hotspots. Keep chargers connected, screens unlocked, and the Watch app open during restore. Pause large iCloud Photo or Files sync on the new iPhone until the watch finishes.
Delete unused watch apps before unpairing to shrink the backup by hundreds of megabytes. If your backup is very large, a computer-based encrypted iPhone backup often restores faster. For a style refresh after setup, consider new Apple Watch straps that match your daily wear.
Protect your new setup
Enable a 6-digit passcode and Wrist Detection for theft protection. Turn on Find My and activation alerts for your Apple Watch 11. Review privacy settings for Health, Location, and Siri to keep sensitive data secure.
Revisit emergency features like Medical ID and Fall Detection. Test notifications and Focus modes to prevent missed alerts. Finish with charging and protection essentials - check Apple Watch accessories for stands, cases, and cables.
FAQ
Do I need to erase my watch first?
No. Unpairing from the old iPhone safely erases the watch and creates a backup automatically. Then you restore that backup to the new iPhone during pairing.
Will I lose my Activity awards?
No, awards and trends restore with Health data when using an encrypted backup or iCloud Health sync. Give Fitness a few minutes to rebuild graphs.
What about Apple Pay and transit cards?
For security, cards never migrate in backups. Re-add each card after pairing, which typically takes under 2 minutes per card.
Does Family Setup transfer the same way?
Yes, but manage it from the organizer iPhone. Unpair to back up, pair on the new organizer, then restore and reassign the managed line.
How long should I wait before retrying?
If pairing fails, restart both devices and wait 2 minutes. Try again with chargers connected and Bluetooth toggled.
Conclusion
To transfer your Apple Watch to a new iPhone, unpair the watch from the old iPhone to create an encrypted backup, then pair it with the new iPhone and choose Restore from Backup. Keep both devices updated, charged, and connected, and within 10 to 30 minutes your Apple Watch 11 will feel instantly familiar.
