I restarted my Moto G, changed Location to battery preserving mode and uninstalled the Instagram app which is a big fat battery hog. This fixed the battery drain for me.
Greetings from Sweden. :)
I've deleted data and cache in Settings:Apps:Chrome and restarted the phone.
Then I see the problem in red: encryption password which I have no clue what it can be because I can't recall ever setting such a password. I have no clue how to fix this. :(
I own a Moto G but this issue exists in fact in that phone as well why it's puzzling to see this thread posted as a Samsung-specific problem which it isn't. It's an Android problem.
Sync works except "Inbox" which I switched off and then I turned off Chrome's notifications in Settings:Apps:Chrome to get rid of the useless notification. This has solved it for now until Google have fixed the annoying bug.
