The quickest way to restart your Samsung watch

A restart clears temporary glitches and refreshes your watch's system without erasing your data or settings. The method depends on which Samsung watch model you own, but most use either a button combination or the settings menu.

For most Samsung watches with a physical rotating bezel or side buttons, hold the power button (usually on the right side) for about 10 seconds until you see the power menu appear. Then select "Restart" or "Reboot" from the menu. If your watch has a touchscreen and no physical buttons, swipe down from the top of the screen to open the quick settings, then tap the power icon and choose restart.

The restart process takes 30 seconds to two minutes. Your watch will turn off, then power back on automatically. You'll see the Samsung logo during startup, and the watch will return to your home screen once it's finished.

Key Takeaways

  • Hold the power button for 10 seconds to open the power menu on most Samsung watches with physical buttons.
  • On touchscreen-only models, swipe down from the top and tap the power icon to find the restart option.
  • A restart takes one to two minutes and does not erase your apps, contacts, or personal settings.
  • If your watch is frozen or unresponsive, a restart is the first troubleshooting step before considering a factory reset.

Restarting a Samsung watch with physical buttons

If your watch has a rotating bezel or side buttons, the power button is your main tool. On Galaxy Watch models (including the Classic, Active, and Pro series), the power button sits on the right side of the case. Press and hold it without releasing—don't tap it once or twice, as that will just turn the watch off instead of opening the menu.

After about 10 seconds, the power menu will appear on your screen. You'll see options including "Power Off," "Restart," and sometimes "Emergency SOS." Tap "Restart" with your finger or use the bezel to highlight it and press the center button to confirm. The watch will shut down and restart automatically.

If the menu doesn't appear after 10 seconds, your watch may be completely frozen. In that case, keep holding the button for another 5 to 10 seconds—some models require a longer hold to force a restart when the system is unresponsive.

Restarting a Samsung watch with a touchscreen only

Watches like the Galaxy Watch5 Pro and some Galaxy Watch4 models rely entirely on touch input. To restart, swipe down from the very top of the watch face to open the quick settings panel. This reveals a row of icons including Wi-Fi, Bluetooth, battery percentage, and a power button (usually a circle with a line through it).

Tap the power icon. A menu will appear with options to power off or restart. Select "Restart" and confirm. The watch will power down and come back on within a minute or two. If swiping from the top doesn't work, try swiping up from the bottom of the screen instead—some models use that gesture to access settings.

What happens during a restart and what it doesn't erase

A restart is a soft reset that powers your watch off and back on. It clears temporary data stored in your watch's active memory—things like stuck notifications, frozen apps, or connection glitches—but it does not touch your saved data. Your apps, contacts, calendar events, watch faces, and personal settings remain exactly as they were.

Think of it like restarting your phone: everything you installed and configured stays in place. The restart straightforward gives the system a fresh start, which often fixes problems caused by apps running in the background or minor software hiccups. If you're concerned about losing something, a restart is safe to try.

When to restart versus when to do a factory reset

Start with a restart if your watch is slow, an app keeps crashing, notifications aren't working, or the screen is unresponsive. A restart solves most of these problems and takes only a couple of minutes. If your watch is completely frozen and won't respond to button presses or touches, hold the power button for 15 to 20 seconds to force a restart.

A factory reset is different and much more drastic—it erases everything and returns your watch to its original state. Only do a factory reset if a restart doesn't fix the problem, or if you're selling or giving away the watch. To factory reset, go to Settings > About > Reset, then confirm. This process takes several minutes and you'll need to set up your watch again afterward.

Troubleshooting if your watch won't restart

If the power menu doesn't appear when you hold the button, your watch's battery may be completely drained. Connect it to its charger for at least 15 minutes, then try again. Some watches won't respond to any input when the battery is critically low.

If the watch is charged but still won't respond, try holding the power button for a full 20 seconds without releasing. Some models require a longer hold to force a restart when they're stuck. If that doesn't work, leave the watch on its charger overnight, then attempt the restart again in the morning.

If your watch still won't restart after these steps, the device may have a hardware problem or a serious software issue that requires professional service. Contact Samsung support or visit an authorized service center with your watch and proof of purchase.

Restarting after a software update

After your watch installs a software update, it usually restarts automatically. However, if the update completes but your watch seems stuck on a loading screen or the update screen, you can manually restart it using the same method as above. This helps the system finish explore the update properly.

If your watch is stuck on the Samsung logo or a boot screen for more than five minutes after an update, hold the power button for 15 seconds to force a restart. The update process will resume when the watch powers back on.

Frequently Asked Questions

Will restarting my Samsung watch erase my data?

No. A restart only powers the watch off and back on. All your apps, contacts, messages, settings, and watch faces stay exactly as they are. A restart is safe and won't cause any data loss.

How long does a restart take?

The restart process usually takes one to two minutes from the moment you select "Restart" until the watch is fully powered back on and ready to use. You'll see the Samsung logo during startup.

What's the difference between restarting and turning the watch off?

Turning off powers down the watch and leaves it off until you press the power button again. A restart powers the watch off and then automatically powers it back on. A restart clears temporary memory and fixes glitches; turning off just stops the watch.

Can I restart my watch if it's frozen?

Yes. If your watch is frozen and won't respond to taps or button presses, hold the power button for 15 to 20 seconds to force a restart. The watch will power down and restart even if it appears completely stuck.

Should I restart my watch regularly?

You don't need to restart regularly as part of routine maintenance. Restart only when you notice problems like slowness, app crashes, or unresponsiveness. Most people restart their watch a few times a year when needed.
