Mine went back today, which is a real shame because functionality (beyond battery life) and aesthetics was exactly what I wanted. What is the best way to keep track of updates? I'd consider buying again if the battery issue is resolved.
Had my watch a week and was initially disappointed with the battery having come from Fitbit Versa which had great battery life.
However, I've found turning off Wi-Fi and location when not needed has made a huge difference. Makes no difference to watch functionality and reckon I'll now get over 2 days on a charge.
Other than this the watch is everything I had hoped!
I had the exact same problem... battery life went down by ~1/2 after the watch software updated.
- Backup your watch settings first, via the Galaxy Wear app on your phone
- On the watch, go to settings and complete a Reset
- Restore your watch settings using the Galaxy Wear app
Worked like a charm for me.
