Macbook Air - battery drains while sleeping (but not when shut down)
I have had the same problem occur to me after a completely new battery was installed in a MacBook Air from late 2011. From 100% I woke up the next day to find the battery at 28%.

So I dug up some research I had done and it comes to this command:

sudo pmset -a hibernatemode 25

From examining your setting I see yours is not 25 but 3, if you have not found a solution for your problem, this could be it.

Here is some additional read on this from the Apple Discussion Forums: https://discussions.apple.com/thread/4729695?start=0&amp;tstart=0

You can see some pros and cons of doing this. I quote the documented differences:

hibernatemode = 3 by default on supported portables. The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from disk image.

hibernatemode = 25 The system will store a copy of memory to persistent storage (the disk), and will remove power to memory. The system will restore from disk image. If you want "hibernation" - slower sleeps, slower wakes, and better battery life, you should use this setting.

If I notice better results I shall do well to post them here as backing evidence. Good luck!
