I am not sure what happened, but I went from 5 day battery life to just under 2 days in the past week. I tried a reset, but still 2 days. I am not sure what has happened. I am dissapointed, I now feel like I am wearing a faulty watch and not sure I would want to invest again in this type of technology when there are so many issues and very few fixes.
I use an iPhone with my Galaxy Watch 46mm and since 2 charges ago, my watch came back to 5 days charge. I did not do any reset or anything. It just came back to perfect condition out of nowhere. The only thing that I did was connecting the Bluetooth first to the connection without the LE and the to the LE connection. After that, I am back to the 5 days battery. This solution seems weird but that is how I remember that I went back to normal. Please share if it does work for you.
Not the BlueTooth trick fixes my drain issue. In order to preserve battery power I put my watch in Flight mode during the night, and to my surprise it switched back to the former low power usage. My watch now lasts almost 6 days on a single charge!!
I have a 46mm watch, and I wonder what might have happened here? Is there some internal software switch which flipped it from 42mm mode to 46mm mode?
Curious about what Samsung thinks of this. Also curious whether this solves your power drain issue too!
I am now experiencing the exact same issue.
Galaxy Watch 46mm battery life going from 4-5 days to under 2 days!
This is very poor, since my watch will run out of battery if i forget to charge it at night...also I use it to monitor my sleep...or at least, i did :-(
SAMSUNG PLEASE FIX THIS SOON!
