You can change a sleep record in Samsung Health by opening the app, finding the sleep entry you want to edit, and either updating the time or deleting it entirely

Samsung Health stores sleep data automatically if you wear a compatible Samsung device, or you can log sleep manually. Once a sleep record is saved, you can open it again to change when you went to bed or woke up, or remove it from your history. The steps differ slightly depending on whether you logged the sleep yourself or the device recorded it automatically.

The process takes less than a minute. You do not need to uninstall the app, restart your phone, or contact Samsung support. If you made a mistake about the time, recorded sleep on the wrong day, or want to delete a record entirely, you can do that from within the app itself.

Key Takeaways

  • Open Samsung Health, tap the Sleep tile, and find the date of the record you want to change.
  • Tap the sleep entry itself to open the details screen, where you can edit the bedtime and wake time or delete the record.
  • Changes save immediately; you do not need to confirm or submit anything after editing.
  • If you cannot find the sleep record, check that you are looking at the correct date and that the record was actually saved.

How to Edit the Time on an Existing Sleep Record

Start by opening the Samsung Health app on your phone. Look for the Sleep tile on your home screen — it usually shows a moon icon and displays your last night's sleep duration. Tap on the Sleep tile to open the sleep history view.

Find the date of the sleep record you want to change. The app displays sleep entries in a list or calendar format depending on your phone model and app version. Once you locate the correct date, tap directly on that sleep entry to open the full details screen.

On the details screen, you will see the bedtime and wake time displayed. Tap on the bedtime field to edit when you went to bed, or tap the wake time field to change when you woke up. A time picker will appear — adjust the hour and minute using the plus and minus buttons or by typing the time directly. Tap outside the time picker or press the back button when you are finished, and the change saves automatically.

How to Delete a Sleep Record Completely

Open Samsung Health and go to the Sleep tile. Find the sleep entry you want to remove and tap on it to open the details screen.

Look for a delete button, usually shown as a trash icon or the word "Delete" at the bottom of the screen. Tap it. Some versions of Samsung Health will ask you to confirm the deletion; others delete immediately. Once deleted, the record no longer appears in your sleep history.

If you delete a record by mistake, you cannot undo it from within the app. However, if you have a Samsung account and Samsung Health is synced to the cloud, you may be able to restore it by signing out and back in, though this is not may provide.

Why Your Sleep Record Might Not Be Editable

If you tap a sleep entry and do not see an edit option, the record may have been synced from a wearable device like a Galaxy Watch. Some Samsung devices lock records that came from a watch or fitness tracker, meaning you can view them but not change the times. In this case, you can only delete the record, not edit it.

Another reason you might not see edit options is if the app version on your phone is outdated. Check the Google Play Store or Samsung Galaxy Store to see if an update is available. After updating, try opening the sleep record again.

What Happens to Sleep Data After You Edit or Delete It

When you change the time on a sleep record, Samsung Health updates the duration and any statistics that depend on it — such as your weekly average sleep or sleep trends. The old time is replaced completely; the app does not keep a history of what you changed.

If your Samsung Health account is synced to a Samsung account or to Google Fit, the change may take a few minutes to sync across devices. If you use multiple phones or a smartwatch, check those devices after editing to confirm the change appeared.

Manually Logging Sleep Instead of Relying on Auto-Detection

If you find yourself editing sleep records often because auto-detection is inaccurate, you can turn off automatic sleep tracking and log sleep manually instead. Open Samsung Health, go to Settings, find Sleep, and toggle off automatic detection. Then, each night or the next morning, you can manually enter your bedtime and wake time by tapping the plus button on the Sleep tile and selecting "Add sleep."

Manual logging gives you full control over the times recorded and is often more accurate if you nap during the day or if your device does not detect sleep reliably. You can still edit or delete manually logged entries using the same steps described above.

Frequently Asked Questions

Can I edit a sleep record from a Samsung Galaxy Watch?

You can delete it, but most Galaxy Watches do not allow editing of sleep times directly from the phone app. If the watch recorded the sleep, the record is usually locked. Try opening Samsung Health on the watch itself to see if you can edit it there, or delete the record from your phone and log the sleep manually instead.

What if I logged sleep on the wrong date?

Delete the incorrect entry and create a new one with the correct date. Open Samsung Health, find the wrong entry, delete it, then tap the plus button to add a new sleep record. Select the correct date and enter the bedtime and wake time.

Does editing a sleep record affect my health data or statistics?

Yes. Samsung Health recalculates your sleep averages, trends, and any health insights based on the updated time. If you change a record from seven hours to five hours, your weekly average will shift accordingly.

Will my edited sleep data sync to my smartwatch?

If your watch and phone are synced through Samsung Health or Google Fit, changes usually sync within a few minutes. Check your watch's health app to confirm the update appeared. Some older devices may not sync edits, so you might need to delete and re-log the entry on the watch itself.
