It started a few weeks ago where it started to drain the battery really quickly. So I took off Bluetooth, but that didn't change anything. I switched over to battery saver mode and the battery was back to normal. After a few days, I tried to switch over again to Normal but the same happened. I have tried to reset the watch and shut it down and turning it on again nothing have help.
Hey @Buch! Firstly, check for any software updates for your smartwatch: open the Galaxy Wearable app > About Watch > Update Watch Software > Update Now. Are there any updates available? Also, has the smartwatch been in either a very hot or very cold location? Have you recently installed new apps? When you aren't using it, do you use Sleep Mode?
