Bedtime Mode on Samsung Galaxy Watch: How to Use It

Bedtime Mode on a Samsung Galaxy Watch is a built-in feature that silences notifications, turns off the display, and disables the raise-to-wake gesture so you can sleep without interruptions. You can turn it on manually from the quick settings panel, schedule it to match your sleep hours, or let it activate automatically when you start a sleep tracking session. This article explains what the mode actually does, how to set it up on both the watch and the connected phone, and how to fix common issues like the watch not waking you up with an alarm.

What Bedtime Mode Actually Does

When you enable Bedtime Mode on a Galaxy Watch (running Wear OS, which includes Galaxy Watch 4 and newer models), the watch enters a low-interference state designed for sleep. Specifically, it:

• Mutes all notifications and calls – the watch will not vibrate, chime, or light up for incoming alerts.
• Turns off the always-on display and the raise-to-wake gesture, so the screen stays dark until you touch it or press a button.
• Prevents the watch from waking you with sounds or vibrations, except for alarms that you have explicitly set.
• Keeps the watch face dimmed and simplified if you do tap the screen, showing a minimal clock by default.

It does not turn off the watch, stop heart rate or SpO2 tracking, or disable the alarm clock. Sleep tracking continues normally while Bedtime Mode is on, as long as you are wearing the watch.

How Bedtime Mode Differs from Do Not Disturb and Theater Mode

Galaxy Watch has three similar but distinct modes, and it is easy to confuse them:

• Do Not Disturb (DND) – silences notifications and calls but leaves the screen fully functional. Raise-to-wake and the always-on display still work, so you can glance at the time without touching the watch.
• Theater Mode – turns off the screen and mutes all sounds, but it also blocks the touchscreen and buttons to prevent accidental activation during a movie or performance. It does not affect notifications (they are just not shown because the screen is off).
• Bedtime Mode – combines DND’s notification silencing with the screen-off behavior of Theater Mode, but keeps the touchscreen responsive so you can check the time if you really need to. It also integrates with sleep tracking and scheduled routines.

In practice, you should use Bedtime Mode for sleeping, DND for meetings or focused work, and Theater Mode for a movie theater or a dark room where you do not want the screen to light up at all.

How to Turn On Bedtime Mode Manually

The quickest way to enable Bedtime Mode on your Galaxy Watch is from the quick settings panel:

1. On the watch face, swipe down from the top of the screen to open the notification shade.
2. Swipe down again (or scroll) to see the full quick settings grid.
3. Tap the Bedtime icon (a crescent moon). If you do not see it, tap the edit (pencil) icon, drag the Bedtime toggle into the grid, and then tap it.
4. The watch will confirm that Bedtime Mode is on. The screen will stay dark until you tap it.

To turn it off, swipe down and tap the same icon again. You can also say “Hey Google, turn on Bedtime Mode” if you have Google Assistant enabled on the watch, or press the Home button twice to open the app drawer and use the Settings app.

How to Schedule Bedtime Mode

Scheduling is the most useful feature because it automates the mode for your typical sleep hours. You can set it up on the watch itself or on the Samsung Health app on your phone.

On the watch:

1. Open Settings (gear icon) on the watch.
2. Scroll to Advanced features (or “Modes” on newer versions) and tap Bedtime.
3. Tap Schedule and set a start and end time (e.g., 11:00 PM to 7:00 AM).
4. Optionally, enable Repeat for specific days (e.g., weekdays only).

On the Samsung Health app (Android/iOS):

1. Open Samsung Health on your phone.
2. Go to the Sleep tile (or the “Sleep” section in the bottom menu).
3. Tap the three-dot menu (⋮) and select Sleep settings (or “Bedtime mode” on some versions).
4. Enable Bedtime mode and set the schedule. The schedule syncs to the watch via the Galaxy Wearable app.

If you also use a Samsung phone, you can link Bedtime Mode to your phone’s own Bedtime Mode or Digital Wellbeing schedule, so both devices go quiet at the same time. On the watch, this is under Settings → Advanced features → Bedtime → Sync with phone (if available).

How to Use Bedtime Mode with Sleep Tracking

Bedtime Mode is closely tied to sleep tracking in Samsung Health. When you start a sleep tracking session manually (by tapping the moon icon in the Samsung Health app on the watch), the watch will automatically turn on Bedtime Mode. Conversely, if you have scheduled sleep times, the watch will suggest turning on Bedtime Mode when the schedule starts.

To get the most accurate sleep data (REM, deep, light stages), keep Bedtime Mode on all night. The watch continues to measure your heart rate, blood oxygen, and movement. In the morning, you will see a sleep score and a breakdown of stages in Samsung Health. If you forget to turn off Bedtime Mode, it will automatically turn off at the scheduled end time, or when you stop the sleep tracking session.

Common Issues and Fixes

Here are the most frequent problems users encounter and how to solve them:

• Alarm does not sound or vibrate during Bedtime Mode. Check that the alarm is set on the watch (not just on the phone) and that the watch is not in Theater Mode. Also, ensure the watch is not on silent or muted. Bedtime Mode does not block alarms, but if the watch is in Theater Mode, alarms are silenced.
• Bedtime Mode turns off by itself. If you have a scheduled end time, it will turn off at that time. If you have “Auto off with alarm” enabled (in Settings → Advanced features → Bedtime), the mode will end when your alarm goes off. If you do not want that, disable that option.
• Notifications still appear. Bedtime Mode should mute all notifications. If you see notifications, you may have turned on “Show notifications” in the Bedtime settings (some versions allow exceptions). Go to Settings → Advanced features → Bedtime and check the exception list.
• Watch screen lights up when you move. Bedtime Mode disables raise-to-wake, but if you have “Touch screen to wake” enabled, tapping the screen will wake it. That is normal. To prevent any wake, use Theater Mode instead.
• Bedtime Mode is not available on my watch. Bedtime Mode is available on Galaxy Watch 4 and later (Wear OS). Older Tizen-based watches (Galaxy Watch 3 and earlier) have a similar “Do Not Disturb” but not the dedicated Bedtime Mode. If you have a newer watch and cannot find it, update the watch software via the Galaxy Wearable app.

Frequently Asked Questions

Does Bedtime Mode stop sleep tracking?

No. Bedtime Mode is designed to work with sleep tracking. It silences notifications and turns off the screen, but the sensors continue to record your heart rate, movement, and blood oxygen. You can start a sleep tracking session manually, and the watch will automatically enable Bedtime Mode.

Will my alarm still go off in Bedtime Mode?

Yes, alarms you set on the watch will sound and vibrate normally, even in Bedtime Mode. The mode only blocks notifications and calls, not alarms. If your alarm is on your phone, it will also go off, but the watch will not relay it if Bedtime Mode is on.

Can I set Bedtime Mode to turn on automatically when I go to sleep?

Yes. You can schedule Bedtime Mode for specific times, or you can start a sleep tracking session manually, which automatically enables Bedtime Mode. Some watches also suggest Bedtime Mode when they detect you are falling asleep, but that is not a guaranteed automatic feature.

Does Bedtime Mode save battery?

Yes, indirectly. Because the screen stays off and notifications are silenced, the watch uses less power during the night. However, sleep tracking still uses sensors, so the battery savings are modest. You should still charge your watch before bed if it is below 30%.

How do I turn off Bedtime Mode in the morning?

Swipe down from the top of the watch face, then tap the Bedtime icon (crescent moon) to turn it off. If you have a schedule, it will turn off automatically at the end time. If you used sleep tracking, stopping the tracking session will also turn off Bedtime Mode.

Can I use Bedtime Mode on a Galaxy Watch 3?

No, Bedtime Mode is a Wear OS feature introduced with the Galaxy Watch 4. On older Tizen-based watches, you can use Do Not Disturb and Theater Mode, but they do not have the combined Bedtime Mode. You can still schedule DND on those watches, but it will not have the same sleep-tracking integration.
