Just bought a NEW Galaxy watch 4 classic (730E), Bluetooth model (no LTE). Model SM-R890.
Battery usage is good during the day, but at night, while on the charger, it is charging, but if I leave it on the charger all night, it discharges. I've only had it 2 weeks. I've put it on the charger and checked on it every so often, and in under 2 hours it is at 100%. Leaving it on the charger all night, and it's very low or at 0% in the morning. If I turn the watch off, it will charge fine and in the morning it will be at 100%. However, I shouldn't have to turn it off to charge it
I am having the same problem. It wasn't until the latest update that it started doing this. I also have a Galaxy Watch 4 but that one does not have the same charging/draining issue. I wish there was a good answer...
Thank you for reaching out. I can certainly understand your frustration with the watch battery draining rapidly overnight. Are you using the original charger that came with the watch?
