If your Samsung Galaxy Watch will not turn on, first place it on the charger made for your watch model and check that it is aligned, clean, and dry. If it remains unresponsive, press and hold the Home/Power and Back buttons together for at least 7 seconds to force a restart. This reboot does not erase personal data.
How to turn on or restart an unresponsive Galaxy Watch
-
Place the watch on a compatible charger and check for a charging indicator. A fully depleted battery can make the screen appear dead. Samsung Gulf advises allowing at least one hour in its charging troubleshooting sequence; that is regional guidance, not a guaranteed charging time for every watch.

If the watch still does not respond, press and hold the Home/Power key and Back key together for at least 7 seconds, until the screen goes dark. Release the buttons and wait for the reboot message. Samsung says this forced restart does not erase personal data; it is not a factory reset. See Samsung’s instructions for a Galaxy Watch that appears not to turn on.

Make sure the charger matches your watch
Galaxy Watch charging accessories vary by generation. Samsung recommends using a compatible Samsung wall charger with a charging dock that matches the watch. Many newer watches use a flat magnetic charging pad; the original Galaxy Watch, Gear S3, and Gear Sport use an older dock. Galaxy Fit bands use their own charging cradles, not Galaxy Watch chargers. Check the exact watch model and your region’s support listing before using or buying a replacement.

If the watch or charger is unusually hot, stop charging and let it cool before trying again.
Samsung’s US troubleshooting guide also recommends the charger and adapter requirements listed for your watch model.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What to try if there is no charging indicator
Check the wall outlet, adapter, cable, charger compatibility, and watch alignment. Try a suitable wall adapter and remove any case or other obstruction that keeps the watch from contacting the charging surface correctly. If charging is slow or keeps stopping, confirm that the watch and pad are clean and dry and that the power source meets the model’s requirements.
Can you charge a Galaxy Watch from a phone?
Wireless Power Sharing is a backup option only for supported phone-and-watch combinations. Samsung’s US and Canadian guidance lists Watch4, Watch5, and Watch6 series and some earlier models as supported, while excluding Watch7 and newer generations in its current guidance. Phone compatibility, battery level, case, and alignment can also affect whether sharing works. Check Samsung’s US compatibility guidance or the relevant local support page before relying on this method; it is not a universal substitute for the dedicated charger.
When to contact Samsung support
Contact Samsung support or a service center if the watch still will not charge or turn on after you have tried a compatible charger and the checks above. Do the same if there is visible damage, a stuck button, or water exposure. Do not keep charging a device that becomes unusually hot; allow it to cool and seek support. Samsung Gulf’s guidance on why a Samsung smartwatch may not charge or turn on also recommends service when troubleshooting does not resolve the issue.
