The following labels are not available here: I'm experiencing a MASSIVE battery drain when the Galaxy Watch is connected via 4G. The battery can go down by 50% in just a couple of hours! The smartwatch also heats up and freezes. I think there's a serious issue with the last software update. When I'm connected via BT only with the 4G deactivated the battery can last up to 4 days, so no issues. However, 4G connectivity is simply a DISASTER. Something's definitely wrong.
