So I've heard on the internet that I don't have to (or even shouldn't) turn off my Mac. Instead it is suggested to put it to sleep (something about Unix running maintenance processes during night). Also a friend of mine was telling me his MBA eats about 1-2% battery during night.

I've tried putting my rMBP to sleep for a few days now (basically closing lid). Power Nap is turned off, I quit all Apps before I put it to sleep. Despite all this I get about 12-14% battery drainage during 12 hours.

What might be the cause? Is it normal?

In order for any computer to sleep, it needs to keep it's ram contents and ram uses power, even if a tiny bit.. I am not sure when mac's start to hibernate but I'm assuming this is where the battery drain comes from.

Roughly 1% per hour is the norm.
