Introduction
If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling your watch. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
You might need replacement adhesive to reattach the battery when reassembling the device.
What you need
Step 1
Turn off the watch
- Turn off the Galaxy Watch Active by pushing and holding the bottom button for approximately 3 seconds. You should feel a short vibration.
- When the “Power off” symbol appears tap the center of the screen to make it shut down. You should feel a longer vibration for confirmation.
