    Hello,

    I'm going on a flight from the UK to Mauritius for a few weeks. The journey is slated to be approximately 12 hours, to a maximum of 13 hours.

    I plan to have my MacBook Air (13" 2011) available with me for the duration of the flight. Hence, I require some advice on battery conservation.

    Obviously, I will not use the MacBook Air for the full flight duration, or I hope I won't - I'll somehow need to sleep for a few hours, as it is a night flight.

    Right, to the point - how can I conserve battery life for this flight?

    I'm a web developer and may want to do some web development on the MacBook Air. I've installed an IDE with the lowest RAM usage available, and will hopefully work through some scripts. I've also installed Zend Server CE, for testing my web development. It installed Apache, MySQL and a few other Apache modules.

    Thanks for any tips :)

    Err . . . turn it off when you have your dinner, keep the screen brightness down, and only use the apps you need. :cool:

    Unless there's wifi onboard, disable all of your wireless connections - bluetooth, wifi, etc.

    There really isn't much you can do that you probably haven't already thought of.

    How low can you keep the brightness and still be able to work?

    Make sure every app that isn't absolutely essential is quit even the ones in the menu.

    Common sense stuff you probably have thought of.

    What I do is carry an adaptor for the airplane, but this isn't an option on every flight.

    You could just buy one of those devices that enables you to charge it on the plane.

    Whether or not they work on your particular plane, I don't know, but I suppose it would.

    If you were already aware of this product though, just ignore this post.

    You Can buy it as an accesory when pur hasing the mba.

    Edit, i see someone beat mé to it, a shame these ipads are so slow to write from.

    The only things I can think of are to turn of WiFi, bluetooth, exit apps that you dont' need, keep the laptop as dim as possible, turn of Backlight keyboard, try to do "light" activities.

    To make your battery last longer, turn off Bluetooth and WiFi, lower your screen brightness, shut down any apps/processes/widgets that you're not using, etc. For more tips, read the BATTERY LIFE FROM A CHARGE section of the following link. This should answer most, if not all, of your battery questions:

    In addition to all the other good ideas I would like to add a few of my own. Turn off wifi, turn off bluetooth, lower screen brightness, and finally shut down any apps or unnecessary processes that might be running.

    That's what I just said, in addition to other things.

    Yeah, but has anyone mentioned turning off wifi and bluetooth yet? He should probably also quit anything he's not using and turn down the screen brightness.

    That's really good advice. I'll just add that turning the screen brightness down also helps.

    One other thing you might like to consider is buying an extra battery.

    And sine you're on a plane, you might as well turn off wifi and Bluetooth. You'll probably be fine with a low backlight level too.

    The battery in the MacBook Air is not user-removable.

    Some airplanes (especially those designated for longer flights) have started to be fitted with standard outlets under the seat (actual outlets, not the special airplane ones). My last JFK-LAX flight on Continental had this. Check with your airlines - you might be able to plug your computer in and not worry about preserving the battery. :D

    Then your suggestion of buying an extra battery is pointless, since they wouldn't be able to swap them out.

    Sure you could. It's just not practical. With the UK's anal security screening you probably wouldnt be able to get the screwdrivers on board anyway.

    I take 14 hrs flight every 5 months (chicago to korea)
    I barely use my laptop, I am too busy watching the free movies offered and eating so much and reading my books :p
    Trust me, I dont even sleep during flights and they are a breeze. dont worry just enjoy your flight and make sure you carry extra clothes and a passport :) (tooth brush is optional)

    I think he was suggesting an external battery. An expensive, but effective option. Probably overkill unless the OP makes a habit of travelling for long periods away from power.

    Since he said "extra battery" and not "external battery", it indicates another battery of the same type already in the MBA.

    If you had posted that you would be saying the opposite "an external battery is still an extra battery". You can admit you misinterpreted, it's ok. :)

    No, it really doesn't. If I'd said replacement battery, it would.

    I didn't misinterpret; it wasn't stated clearly. An "extra" battery gives the impression of Mac portables that come with a removable battery, so you can buy an extra one and swap them out when one is drained. An "external" battery is clearly a non-Apple battery that isn't swapped with the internal battery. Either way, now it has been clarified.
