You can change a sleep record in Samsung Health by opening the app, finding the sleep entry, and either editing the time or deleting it entirely
Samsung Health tracks your sleep automatically if you wear a compatible Samsung device, but the app sometimes records the wrong times or picks up naps you didn't intend to log. You can fix these records by hand. The process takes less than a minute and works the same way whether you want to adjust when you fell asleep, when you woke up, or remove the entry completely.
Your sleep data stays on your phone unless you delete it. If you sync Samsung Health to a Samsung account, changes you make in the app will update across your devices. If you do not use a Samsung account, edits only affect the phone where you made them.
Key Takeaways
- Open Samsung Health, tap the Sleep tile, and select the date of the record you want to change.
- Tap the three-dot menu on the sleep entry to edit the times or delete the record.
- When you edit sleep times, you can change when you fell asleep, when you woke up, or both.
- Deleted records cannot be recovered, so check the times before you confirm the deletion.
- Changes sync to your Samsung account if you have one set up, but only affect this phone if you do not.
How to edit a sleep record step by step
Start by opening Samsung Health on your phone. Tap the Sleep tile on the home screen — it usually shows a moon icon and your sleep from the previous night. If you do not see the Sleep tile, swipe down to find it or tap the menu button to add it.
Find the date of the sleep record you want to change. If it is recent, it will appear at the top of the list. Tap the entry to open it. You will see the time you fell asleep, the time you woke up, and how long you slept total.
Tap the three-dot menu icon in the top right corner of the sleep entry. A menu will appear with two options: Edit and Delete. Tap Edit. The app will open a screen where you can change the sleep and wake times.
Tap the time you want to change. A clock picker will appear. Adjust the hour and minute by tapping the up and down arrows or by typing the time directly. When the time is correct, tap OK or Done. Repeat for the wake time if you need to change that too. Once both times are set, tap Save at the bottom of the screen.
How to delete a sleep record
Open Samsung Health and tap the Sleep tile. Find the sleep entry you want to remove and tap it to open the details. Tap the three-dot menu icon in the top right corner and select Delete.
The app will ask you to confirm the deletion. Tap Delete again. The record will be removed when ready and will not appear in your sleep history or statistics. Samsung Health will no longer count that night toward your average sleep time.
If you delete a record by mistake, you cannot undo it through the app. You would need to manually add the sleep entry again by tapping the plus button on the Sleep tile and entering the date and times.
Why Samsung Health might record the wrong sleep times
Samsung Health uses motion sensors in your phone or watch to detect when you are asleep. If you leave your device on your bed while you are awake — reading, scrolling, or lying still — the app may think you are sleeping. Similarly, if you take a nap and forget to turn off sleep tracking, it will log that nap as a separate sleep session.
The app also sometimes records sleep that started before midnight as part of the previous day. If you fell asleep at 11 p.m. on Monday and woke at 7 a.m. on Tuesday, Samsung Health might split that into two entries or assign it to the wrong date. Editing the times or deleting the incorrect entry keeps your sleep log accurate.
If you notice Samsung Health is consistently recording the wrong times, check that your device is synced to the correct time zone. Go to your phone's Settings, tap General Management, then Date and Time, and make sure Automatic Date and Time is turned on.
How sleep data syncs across your devices
If you have a Samsung account and you signed into Samsung Health with it, any changes you make to a sleep record will sync to your other Samsung devices within a few minutes. This means if you edit a sleep entry on your phone, the same edit will appear on your Galaxy Watch or tablet.
If you do not have a Samsung account or you did not sign in, your sleep data only exists on the phone where you recorded it. Edits and deletions will not affect any other device. To set up a Samsung account in Samsung Health, open the app, tap your profile icon in the top left, and follow the sign-in steps.
What happens to your sleep statistics when you change a record
Samsung Health calculates your average sleep time, sleep trends, and sleep quality based on all your recorded sleep entries. When you edit a sleep record, the app recalculates these statistics using the new times. If you change a night from 6 hours to 7 hours, your weekly average will increase slightly.
When you delete a sleep record, that night is removed from all calculations. If you had 7 nights of sleep data and you delete one entry, Samsung Health will average the remaining 6 nights. This can change your weekly or monthly sleep average, especially if the deleted night was unusually long or short.
Frequently Asked Questions
Can I edit a sleep record from months ago?
Yes. Open Samsung Health, tap Sleep, and scroll back through your history to find the date you want to change. Tap the entry and use the three-dot menu to edit or delete it. There is no time limit on how far back you can go, as long as the record exists in your app.
What if I do not see the Sleep tile on my Samsung Health home screen?
Swipe down on the home screen to see more tiles, or tap the menu button (three horizontal lines) and look for Sleep in the list. You can also tap the plus icon to add the Sleep tile back to your home screen if you accidentally removed it.
Does editing a sleep record on my phone change it on my Galaxy Watch?
Only if you signed into both devices with the same Samsung account. If you did, changes sync automatically within a few minutes. If you use different accounts or did not sign in, edits only affect the device where you made them.
Can I add a sleep record manually if Samsung Health did not record it?
Yes. Open Samsung Health, tap the Sleep tile, and look for a plus icon or add button. Tap it, enter the date and the times you fell asleep and woke up, and tap Save. The entry will appear in your sleep history and count toward your averages.
What if I delete a sleep record by accident?
Deleted records cannot be recovered through the app. You will need to add the sleep entry again manually by tapping the plus button on the Sleep tile and entering the date and times from memory. Keep this in mind before you confirm a deletion.
