Power Nap on Battery?

[Scuba629]

I guess u have to turn this on? Has anyone checked out their battery life using it?

My mid-2011 Air seems to be losing about 15% charge per day since Power Nap got installed. It was < 3% per day on Lion.

I've turned it on on my mBA but haven't really kept an eye on the battery to be honest...It backs up, collects email and also has alerted me and downloaded an app update...Of course the install needed my password, so it just sat there ready...It's a nice touch, but not a feature I use a lot as yet.

Also curious about this. Anyone with experience?
