How to Force Your Apple Watch to Sync with Your iPhone

As long as you have Bluetooth and Wi-Fi enabled, your Apple Watch should stay in sync with your iPhone. But there are times when Apple Watch just won’t sync health, activity, or other data. Here’s how you can force your Apple Watch to sync with your iPhone.

To force Apple Watch to sync with your iPhone, you have to reset sync data. But before you get there, see if all connections between the Apple Watch and iPhone are enabled.

Open the Control Center on your iPhone by swiping down from the top-right corner of the screen. If you have an older iPhone with a Home button, swipe up from the bottom of the screen.

Swipe down from top-right corner to access Control Center on iPhone

Here, in the “Toggles” menu, make sure the “Bluetooth” and “Wi-Fi” toggles are enabled.

Tap and hold on the toggles panel in Control Center

If your Apple Watch still isn’t syncing, you can use the force sync method.

Open the “Watch” app on your iPhone. Use Apple’s built-in Spotlight Search if you can’t find the app on your smartphone. Next, from the “My Watch” tab, select the “General” option.

Tap on General from the Watch section

From here, swipe down to the bottom of the page and tap on the “Reset” option.

Tap on the Reset option

In the new menu, tap on the “Reset Sync Data” button.

Your iPhone will now erase all contacts and calendar data on your Apple Watch, along with sync settings. Once the process is complete, it will start the sync process over, this time syncing all the data from the Apple Watch to your iPhone (and vice-versa). This should fix your health and activity data sync issues in addition to any problem you might be having with third-party apps.

If you’re still facing sync issues, the last resort is to unpair and repair the Apple Watch.

From the “Reset” menu itself, select the “Erase Apple Watch Content and Settings” option.

Tap on Erase Apple Watch Content and Settings

From the popup, tap on the “Erase All Content and Settings” button to confirm.

Confirm to erase Apple Watch content and settings

Once the process is complete, pair your Apple Watch to your iPhone using the Watch app.
