Is it normal that my Macbook Air 11" drops 1-2% every hour while sleeping?

    I just thought it was a little too much.

    The battery on this thing is AWFUL, btw. Apart from that I love it though.

    I thought the MBAs were supposed to be able to sleep for 30 days? :confused:

    That's in hibernation mode, not sleep mode. It's also possible that the MBA didn't stay in sleep mode the whole time.

    Ok, so how do I make my MBA hibernate? My only options I see are Sleep, Restart, and Shutdown.

    If it shuts down, it won't drain the battery. If it's in standby mode, it's not shut down, so it does use battery power.
    There's your most likely answer.

    Then contact Apple, maybe you have a defective machine.

    Just to be safe, if's it making you unhappy, I'd just shut it down every time, considering it only takes 15 seconds to boot up. :p

    The new MBAs are advertised at the Apple website with a standby of 30 days. So either something is preventing it from going into standby, or there is something wrong with your system.

    Yea but it also says 5 hours wireless web. I really don't know how they got 5 hours with this thing.

    I understand what you're saying though, I will see what happens tonight and then I'll contact Apple. Just so annoying since there are no Apple stores in my country, I'd have to send it to them and everything, right?

    Or can I just go to a retailer?

    Nevermind, I forget I had disabled hibernation and sleep image a while back because I needed the space which I don't anymore.

    That explains why it never went into standby mode. Right?

    Yes, that explains it.

    <facepalm>

    Five hours wireless? Note that Apple tests with Flash disabled. Flash noticeably decreases battery life when web browsing. If you have Flash enabled, you won't get five hours.

    Also to confirm

    When I leave my external monitor plugged in I get bad battery drain

    With nothing plugged in it sleeps nicely. Perhaps a couple of percent which is probably just what it lost before entering deep sleep.

    Im sorry for resurrecting the thread but I really need to know how to enable the hibernation thing.

    My mpa will only sleep but not go into standby mode, I'm losing lots of battery like this.

    How did you do it?

    Google smartsleep.

    or

    Code:
    sudo pmset -a hibernatemode 0 = suspend to RAM only 
    sudo pmset -a hibernatemode 1 = suspend to disk only
    sudo pmset -a hibernatemode 3 = suspend to disk + RAM (default on laptops)
    To see your current mode: pmset -g | grep hibernatemode.

    Apple hibernation has three modes. By default, on laptops it suspends the system and make a copy of RAM to disk for a completely safe hibernate.

    You can change the Mac’s hibernate behavior using pmset; here’s the reference for it:
    http://developer.apple.com/documentation/Darwin/Reference/ManPages/man1/pmset.1.html
    “sudo pmset -a hibernatemode 0″ = suspend to RAM only (default on desktops)
    “sudo pmset -a hibernatemode 1″ = suspend to disk only
    “sudo pmset -a hibernatemode 3″ = suspend to disk + RAM (default on laptops)
    To see your current hibernatemode: “pmset -g | grep hibernatemode”.
