Mine has had the same quick battery drain after the update. However, if I restart the watch after I take it off charge, I will two or three days out of it. If I don't restart after charging, I get about 10 hours.
I have the Zenwatch 2 for more than 2 years now, and ever since I have updated to Android Wear 2.0, battery life has shorten to less than 12 hours. I am now thinking of replacing the battery. Has anyone done that and can give an opinion? its not that...
Well, it's been able to update to Wear OS, though it is the same Android version 7.1.1 with security patch of June 2017. I think every Android Wear with Android Wear 2.0 OS can install this Wear OS. Nothing new, just a rebrand.
