I agree, I think it will settle down after a few days, mine was 60% on day 1 and dropped each day, now about 22%. I to am using about 4% per hour, so that gets you 25 hours on a charge, which is more than enough. Also my estimated time is increasing every day. And remember it's not that it used 33% of your battery, it used 33% of the Apps use, which depending on usage could be 80% or 30% so if it were 30%, that would only be 10% of the total battery use.
I also noticed on my S6 Edge, that the total app usage never reached 100%, which of course it had too. So I wonder if part of the issue is that the battery is now showing us more info? Just wondering.
