Same here. Shame on you, Samsung. I received my watch in Dec 2016, and probably I got a couple of days of charge out of it...at first. That said, a couple of the features advertised weren't even available in Switzerland at the time, and I the battery life was just an extra annoyance from the start. After all, it was advertised as having "up to" 5 days of battery life! Within a year it was down to a day and I'd long since turned off the WiFi and NFC, and since around January 2020 (just over 3 years) it became nearly unusable. I began wearing it in power saving mode. Something like a couple of weeks ago even the power saving mode gave me only something like 2-3 hours of time. Of course I've tried a factory reset...no difference. Software updates, no difference. Yesterday I tried a solution somebody posted on another thread - let the watch die and sit dead for a day, then full recharge and try again. This gave about 6 hours in regular mode today; that's already better but we'll see how it goes tomorrow. What's clear from my own experience and that of countless users online is that the drain seems to kick in overnight. This makes it almost certainly a software issue. If I had to guess, I'd say it's some kind of programmed obsolescence. Maybe Samsung likes watching its customers twist themselves inside out on the forums trying to figure it out, but really they just want us to buy a new watch. Whatever it is - programmed failure or just buggy software - I've been disappointed in this watch so many times that I'm never going back to a Samsung watch. I've seen a few happy Garmin users...maybe that's next.
