Pairing an Apple Watch to a new iPhone is straightforward if you follow the right order

The process works best when you unpair the watch from your old phone first, then pair it to the new one. If you skip the unpair step, the watch may stay linked to the old phone and cause connection problems. The whole process takes about 10 to 15 minutes and requires both devices to be nearby, charged, and connected to the same Wi-Fi network.

You do not need to erase the watch or lose your data. When you unpair, the watch backs up your settings, apps, and activity history to iCloud automatically. When you pair to the new phone, that backup restores to the watch, so your workouts, notifications, and customizations come back exactly as they were.

Key Takeaways

  • Always unpair the watch from your old iPhone before pairing it to a new one, even if you no longer have the old phone nearby.
  • Unpairing backs up your watch data to iCloud, so you will not lose workouts, apps, or settings when you switch phones.
  • Both devices need to be on the same Wi-Fi network and have Bluetooth turned on during pairing.
  • The pairing process takes 10 to 15 minutes and completes when the watch shows a checkmark and the iPhone displays "Pairing Complete".

Unpair the watch from your old iPhone

Open the Watch app on your old iPhone. Tap the My Watch tab at the bottom, then tap the watch name at the top of the screen. Scroll down and tap Unpair Apple Watch. You will see a warning that says unpairing will erase the watch — ignore this. It means the watch will erase its connection to that phone, not that your data disappears. Tap Unpair again to confirm.

The watch will restart and show the Apple logo, then a spinning gear. This takes a few minutes. Once it finishes, the watch screen will show a large red circle with a white line through it — this means it is unpaired and ready for a new phone.

If you no longer have access to your old iPhone, you can still pair the watch to a new phone. Skip this step and go straight to pairing. The watch will ask if you want to unpair from the old phone during setup on the new one.

Prepare your new iPhone and Apple Watch

Make sure both devices are charged to at least 50 percent battery. Turn on Bluetooth in your iPhone settings — swipe down from the top right corner, tap the Bluetooth icon to turn it on. Connect your iPhone to the Wi-Fi network you use at home. The watch will connect to the same network automatically during pairing.

Hold the watch and iPhone close together, about a foot apart. The pairing process uses Bluetooth first, then switches to Wi-Fi once the connection is established. If they are too far apart, the pairing will fail and you will need to start over.

Start pairing on your new iPhone

Open the Watch app on your new iPhone and tap Start Pairing. Point your iPhone camera at the watch face — you will see a circular frame on the screen. Hold the watch still until the camera focuses and the frame turns green. This usually takes 5 to 10 seconds. Once it turns green, the iPhone will say "Pairing in progress".

If the camera cannot focus on the watch face, you can tap "Pair Apple Watch Manually" instead. You will then enter a six-digit code that appears on the watch into your iPhone. This takes longer but works just as well.

Wait for the backup to restore

After the initial pairing completes, the iPhone will ask whether you want to restore from a backup or set up as new. Tap Restore from Backup. The watch will then read your backed-up data — your apps, activity rings, notification settings, and any custom watch faces you created. This step takes 5 to 10 minutes depending on how much data you have.

Do not disconnect the devices or turn off Wi-Fi during this step. If the restore gets interrupted, you can start the pairing process over. The watch will not be damaged, and you can try again.

Complete setup and verify the connection

Once the restore finishes, the iPhone will show "Pairing Complete" and the watch will display a checkmark. At this point, the watch is fully paired to your new phone. You can close the Watch app and use both devices normally.

Check that notifications are working by sending yourself a text message or email. You should see it appear on your watch within a few seconds. If notifications do not arrive, restart both devices by turning them off and back on, then check again. This usually fixes any lingering connection issues.

Troubleshooting common pairing problems

If the pairing fails partway through, the most common cause is that the devices lost Bluetooth connection. Make sure both are close together and try again. If you keep getting an error message, restart both devices completely — hold the side button on the watch until Power Off appears, swipe to turn it off, then turn it back on. Do the same with your iPhone.

If the watch is stuck on the unpaired screen (the red circle), it may not have fully unpaired from the old phone. Go back to the old iPhone if you have access to it and complete the unpair process. If you do not have the old phone, force restart the watch by holding both the side button and the digital crown for 10 seconds until the Apple logo appears, then try pairing again.

If the watch pairs but your data does not restore, check that you signed into the new iPhone with the same Apple ID you used on the old one. The backup is stored in that Apple ID's iCloud account. If you used a different Apple ID, your old data will not be available to restore.

Frequently Asked Questions

Do I lose my activity history and workouts when I pair to a new phone?

No. When you unpair the watch from your old phone, it automatically backs up all your activity data, workouts, and health information to iCloud. When you restore from backup on the new phone, all that data comes back to the watch. Your activity rings and workout history will be exactly as they were.

Can I pair the watch to a new phone if I still have the old phone?

Yes, but you should unpair from the old phone first. If you pair to the new phone without unpairing from the old one, the watch may stay connected to both phones and cause notification and syncing problems. Unpair from the old phone, then pair to the new one.

What if my old iPhone is lost or broken?

You can still pair the watch to a new phone. During the pairing process on the new iPhone, the watch will ask if you want to unpair from the previous phone. Tap Yes, and the watch will unpair remotely using your Apple ID. Then complete the pairing normally.

How long does the whole pairing process take?

The initial pairing takes 5 to 10 minutes. Restoring your backup data takes another 5 to 10 minutes depending on how many apps and how much activity history you have. Plan for 15 to 20 minutes total from start to finish.

Why does my watch keep disconnecting from the new phone?

This usually means the watch did not fully unpair from the old phone. If you still have access to the old iPhone, open the Watch app and complete the unpair process. If the old phone is gone, restart both the watch and the new iPhone completely, then check that you are signed into the new iPhone with the correct Apple ID.
