I have an extended battery for my amazing Note 3 and didn't think that was going well. But later I discovered that Google+ is always using battery most, heating it up and causing slow, so I uninstalled it. Now the battery life has been great with that battery. Using this mpj throughout one day and its still at almost 65%(only 30% before) while going bed.
No idea how Google+ sucking up all my battery!
Unless there's a lot of sync'ing going on for the device over the service I'd assume they currently have a problem between Google+ and the specific device. Either way it's always nice to be rid of software you don't really need. :)
So the syncing was the culprit in battery drain? I had even thought it is a defective phone.
