So I did the reset and woke up this morning with no battery completely dead. I went to bed at 9.30pm with 100% charge. Woke up at 5.30am nothing. So the factory reset didnt fo anything.
Still dont understand why it is only overnight, I managed to charge it a little yesterday morning before work, got 45% that only went down to 20% over the entire 9 hour day, I was out for.
My Gear Sport started doing this same thing 2 nights ago. I factory reset and it seems to he working for now, but I'm afraid to update anything because I've read elsewhere that this is a software issue caused by specific app updates like the weather app. I have no idea what to do, but really hope it gets fixed. The Spotify app is garbage too. It won't allow me to play my downloaded playlists when going for a run. Have to keep uninstalling and re-download my playlists to get it to work so I gave up and bought an armband for my phone. The watch has been a big disappointment.
I did a reboot yesterday and charged my watch before bed to 100%
Woke up at 00.30 and it was already at 60%! 2 hours 40% 🤷🏻♀️ Yesterday day it used less than that for 15 hours.
Switched it on when I woke up but it was totally dead. Once it had a bit of charge I switched it on so I could see what app etc had used what.......
Now I'm more confused than before. I was convinced it was the s.health app.
Someone else mentioned the weather app, which I did update a couple of days before this started happening.
Am going to take to Twitter today
Exact same problem here. Today it only drained 20%, laid down and within an hour it was another 20% down. Something is draining it fast, but only at certain times.
I have tweeted Samsung help UK. Not holding my breath. Informed them of this thread.
Have also backed up and rebooted but not restored.
See where we are again tomorrow
Happening to me since last 3 nights as well. Watch is totally useless now. My Samsung galaxy S9+ also drains around 30% battery at night all of a sudden. Not sure if this two are related.
