thanks for reply!
without update 2.0 do you have multiple darkPME wakes in sytem log? I did this (https://discussions.apple.com/message/20755598#20755598) and the wakes were every 1 hour.
Could you tell the Apple support address to send my problem for statistic?

Yes, before i did 2.0 firmware, I had approx 1 of those activities per hour. After the update every 3 to 5 minutes
I actually called Apple Support and have been working with an analyst and Engineering.

I unpacked update 2.0 with recipe (http://tdev.me/2010/11/extract-acpi-tables-from-firmware-update-file/) and found 2 files with darkPME strings:
Maybe they are responsible for wakes (maybe not )
I have MBA 2011 which is not affected dark wakes and I will try to copy same files to my MBA 2012

UPDATE: I received a call from Apple Support; Engineering confirms that there is a problem with Firmware Update 2.0 (they have heard from other users as well)
So, I guess we will have the same issue until a new update is fixed.
On a curious note: two nights ago after I had done all the updates, I put my computer to sleep, and next day there had been no drainage at all. I checked the console log and there was no "DarkPME (Maintenance)" activity. Very strange. It only happened once.

As an FYI -- I'm having the same issue with my MID MBA 2012. I went to the genius bar 5 times, and tried he following:
Visit 1 - Resetting the SMC (Result: No Success)
Visit 2 - Resetting SMC, DNS Cache, and Sleep Image (This had success for a week, not sure if it was coincidence)
Visit 3 - Reformatted With New Updates Install (Result: No Success)
Visit 4 - Apparently the genius thought the reformat was done wrong at the store (the first time). But i allowed him to do the same thing, so reformatted with new updates (Result: No Success)
Visit 5: No Action, genius representative tried to tell me this was normal activity. I did not agree and requested to raise with an engineer. I'm like there is no way my relatively new computer should be draining 25% + overnight.
Genius Follow Up: Sent me a capture data program. I ran the program and sent the engineer the result. We will see.
Did you guys notice the sudden drain due to any specific reason? Firmware Update, Exposure to Heat, D/L a program etc.? For me, it was really just sitting in my apartment, so i don't see anything physically that changed.
Will keep you posted once the engineer comes back.

Summarizing all post I may notice that sudden battery drain is due dark wakes of macbook - for short period mac wakes to connect WiFi or Lan. If it will happens one time in hour it will be ok, but it repeats every 5 minutes, so battery drains faster. This behavior starts after firmware update 2.0 and Apple engineers know about this problem.
It will be interesting to read engineer's feedback

I found temporary solution of our problem: in terminal I write (no AC connected)
sudo pmset -a standbydelay 86400
Now after 14 hours with closed lid battery of my MBA decreased from 86 to 80%. Before this changes my mac usually lost about 25-30% of charge. In console there was no strings in system.log from 7 am to 8 pm

Same problem here on my MBA 2012.
Waking from hibernate every 5-7 minutes which depletes the battery.
I have fiddled with various pmset adjustments, including only using hibernatemode=25 (i.e. forced hibernation when going to sleep), but the machine still wakes up every 5 minute to do whatever it is doing.
I would really like to have the confidence of hibernate back, so I know for sure that there is just as much juice on the machine as when I left it. Of course we could just shut down, but I really like (the idea of) the auto standby->hibernate feature :-)
I really hope Apple is listening and will issue an update soon.
from the Apple engineer on when to expect an update?

Hi, guys. I found the problem is due to our MacBook can not hibernate properly. Simply disable auto standby->hibernate feature(or set a big value on standbydelay -on battery and autopoweroffdelay - AC connected ) will solve this problem.
Hope this help.
