    hi all i am noticing on my MBA that the battery is not lasting like it did, every time i seem to pick it up its flat,i don't believe it draining any quicker when in use but it seems to be when its not.

    does the new air have a special standby mode? is it possible mine is no going into it ? could something prevent it entering the standby ?

    There is only 5.5% of battery charge left.
    How often do you use it on battery?

    every day, mostly for a few hours surfing the net, again put it down with the battery about 50% yesterday and tonight it was completely flat.

    I noticed the same thing with my MBA the other day. I started using it with a 100% battery and used it until the battery was at about 80%, closed the lid and didn't pick it up for a couple days. Next time I opened it the battery was at around 4%.

    I just assumed it must not have gone into deep sleep, but I haven't figured out the culprit yet. I've got a suspicion that it might be the MS Office 2011 calendar notification app. I'm running OSX 10.6.7.

    Have you checked out the links in my previous post? They may help you identify it.

    I did briefly check it out. I do have bluetooth paired with a Magic Mouse. I've turned bluetooth off and we'll see what happens.
