@laughkay: I'm sorry to hear that you're experiencing battery issues with your Galaxy Watch 4. To get an idea of what might be causing the device to drain so quickly, please charge it to 100%, use it as you would normally until it reaches around 30%, then head to the galaxy Wearable app on your phone > Watch Settings > Battery. If you check the breakdown of your usage below the graph, are any apps or features listed that are using a higher than expected amount of battery (based on your usage)?
In the meantime, please take a look at the steps below in an effort to improve your overall battery life.
- Make sure the device is on the latest software via Settings > Software Update, or on the Galaxy Wearables app via Watch Settings > Watch Software Update
- Disable Watch Always On, if applicable, via Settings > Display > Watch Always On.
- Disable Wi-Fi and Bluetooth when not in use
- Disable unused health features, such as the Heart Rate Tracker, by heading to Samsung Health > Settings > Measurement > Manual Only
-During periods of downtime, head to Settings > Battery > Watch Only > Turn On.
