Samsung Galaxy Watch Health Data Not Syncing to Samsung Health — What It Means & How to Fix It

What Does This Error Mean?

Your Samsung Galaxy Watch workout, heart rate, and health data is not appearing in the Samsung Health app on your phone. This is usually a Bluetooth disconnect, a Samsung Health app permissions issue, or the watch being out of Bluetooth range. Data syncs automatically when the watch reconnects, so most missed data is recovered.

Affected Models

Samsung Galaxy Watch 6
Samsung Galaxy Watch 6 Classic
Samsung Galaxy Watch 5
Samsung Galaxy Watch 5 Pro
Samsung Galaxy Watch 4

Common Causes

Watch was out of Bluetooth range during or after workout
Samsung Health app needs an update
Location permission for Samsung Health app revoked (required for GPS workout data)
Phone battery optimisation killing Samsung Health in the background
Samsung account sync is paused or signed out

How to Fix It

Bring your Galaxy Watch within Bluetooth range of your phone and wait 2–3 minutes.

The watch stores data locally and syncs it to Samsung Health when reconnected. Most 'missing' data appears automatically once the devices reconnect.
Open Samsung Health on your phone and pull down to manually trigger a sync.

Some versions of Samsung Health require a manual refresh to pull new data from the watch. Drag down on the main screen to initiate a sync.
Check battery optimisation: go to phone Settings > Apps > Samsung Health > Battery > Unrestricted.

Android battery optimisation suspends background apps including Samsung Health, which prevents it from receiving data from the watch.
Update Samsung Health and Galaxy Wearable from the Google Play Store.

Outdated apps are the most common cause of sync failures after a watch software update. Keep both apps current.
Sign out and back in to your Samsung account in the Samsung Health app.

A session timeout on the Samsung account can halt cloud sync without showing an obvious error message.

When to Call a Professional

Health sync failures are always software or settings related. If data has been permanently lost (not just delayed), contact Samsung Support — they may be able to recover data from the Samsung Health cloud backup.

Frequently Asked Questions

How far back does Samsung Health store data if not synced?

Samsung Galaxy Watch stores several days of health data locally on the watch before syncing. Once the watch reconnects to your phone, all stored data uploads to Samsung Health automatically. For longer gaps, some older data may be overwritten if the watch storage fills up.

Can Samsung Health sync to Google Fit?

Yes — Samsung Health can share data with Google Fit and other health platforms. In the Samsung Health app, go to Settings > Connected Services and connect your Google account. This allows workout data to appear in Google Fit alongside your Galaxy Watch data.
