I have given up trying to solve this on my own and have put a support call in to Asus.
i think we all need to put some pressure on Asus to get this fixed - having our tablets cooking on idle is a serious problem.
Nice catch; it seems Google Play Services are indeed involved. At a guess, a service is keeping some device open, preventing nvavp from stopping and blocking the tablet from suspending. That goes some way to answering why nvavp is busy.I have the same issue.

I found a topic with some progress (i can not post a link to it so just posting a quotes)

I got a reply from Asus support. In summary: Do a full factory reset, If this does not work then return the tablet to Asus for service.
1. I did a full factory reset, accepted all defaults and allowed all the apps to automatically update. This did NOT fix the problem.
2. I did another factory reset but disabled network locating and did not allow any apps to update. I can say with 100% certainty that my tablet is no longer draining the battery in idle.
I have reported this back to Asus and asked if my tablet should still be returned for service.
Can any one else confirm these results?

I got the same.
I'm planing to spend some time with updating G'apps one by one to check if all of those causing battery drain or it's only one.
