How to charge a Galaxy Watch with or without a charger

How to charge a Galaxy Smartwatch

To take full advantage of your Galaxy watch, make sure to charge it properly. Charge the battery before using it for the first time or when it has been unused for lengthy periods. The actual battery life depends on the Wi-Fi connection, apps used and the frequency of calls and messages. 

Please note: use only Samsung-approved chargers, batteries, cables and dock, as third-party equipment might damage the Galaxy Watch Active. If you need a new charger or charging accessory these can be bought online from the Samsung shop.

If after trying the steps below you are experiencing problems charging your Galaxy watch, you can troubleshoot the problem and book a repair at the Samsung repairs page.

When the battery power is low, the battery icon appears empty. 

1 Plug the charger into a socket and the other end into the charger port
2 Place the Galaxy Watch on the dock, making sure the back is aligned to the centre of the wireless charging dock

Please note: if there are obstructions between the Galaxy Watch and the wireless charging dock (liquid or dust), it may not charge properly

3 When the watch starts charging, the dock’s LED indicator will display a red light

If the watch is turned off, a lightning icon will appear on the screen. Press any of the Galaxy Watch Active’s keys to turn on the watch while it is on the wireless charger and check the charging status by tapping on the screen.

Both the Galaxy Watch and the Galaxy Watch Active can be charged via the innovative Wireless PowerShare function. For example, you can use a Samsung Galaxy S10 as a charging station for the smartwatch.

1 Reveal the notification panel of your smartphone by dragging down from any two points of the top of the screen
2 Tap the Wireless PowerShare icon to turn it on
