    Well it is not normal, the MBA should last a lot longer. MBA 11" is about 5 hours of web surfing and 13" about 7 hours however this is with energy saver settings maxed out. its also only good for 1000 battery cycles, after this the battery life will deteriorate quickly

    Did you read the link I posted before?

    Optimize your battery settings in Energy Saver preferences

    From the Apple () menu, choose System Preferences.
    From the View menu, choose Energy Saver.
    Options in the Energy Saver preference pane will vary depending on your Mac notebook and operating system version. Some examples of items that can be enabled to save power include:

    Putting the hard disk to sleep when possible.
    Slightly dim the display when using this power source. (Choose "Battery" or "Power Adapter".)
    Automatically reduce brightness before display goes to sleep.
    Setting the computer and display sleep sliders to induce sleep of the display or computer more quickly.
    Choosing the Better Battery Life option if available.
    Choosing Automatic Graphic Switching if available.
    Some of these settings will put the hard disk to sleep whenever possible and reduce the computer's microprocessor or graphics performance to maximize its battery life. If you are using processor-intensive applications or graphic-intensive applications, you may wish to change these settings so that performance is maximized at the expense of battery life.

    Graphics performance
    Starting with the MacBook Pro (15-inch, Late 2008), MacBook Pro systems included two separate graphic processing units or GPUs that you could switch between to achieve better battery life or better performance. For more information on this feature, see MacBook Pro (15-inch, Late 2008), (17-inch, Early 2009), (15-inch and 17-inch, Mid 2009): How to set graphics performance. Additionally, the MacBook Pro (15-inch, mid 2010) and MacBook Pro (17-inch, Mid 2010) models enabled automatic switching between the two GPUs in the system for optimal performance based on the task. For more information on models that support automatic graphic switching, see MacBook Pro (15-inch, Mid 2010 and later), MacBook Pro (17-inch, Mid 2010 and later), and MacBook Pro (Retina, Mid 2012): How to set graphics performance.

    Tip: Running graphics-intensive applications such as 3D games, Aperture, iMovie, iPhoto, and others consumes more power. Quitting these applications will allow your computer to switch to the energy efficient graphics processor, which can give you better battery life.

    Turn off unused features and technologies
    Just as you would turn off the lights in an unoccupied room, turning off unused features and technologies can help maximize your battery life, too. Here are a few suggestions:

    Eject CDs and DVDs you're no longer using. Sometimes the optical drive spins to read CDs or DVDs that are in the drive. This consumes a small amount of power.
    Disconnect peripherals when you're not using them. Connected peripherals—such as printers and digital cameras—can draw power from your battery even when you're not using them.
    Shut down any runaway applications.
    Quit any applications that are running but not in use.
    If you're not in a location where you need to use AirPort or Bluetooth, you can turn them off to save power.

    To turn off AirPort from the menu bar:

    From the menu bar, click the AirPort icon .
    From the drop-down menu, choose Turn AirPort Off.
    To turn off Bluetooth from the menu bar:

    From the menu bar, click the Bluetooth icon .
    From the drop-down menu, choose Turn Bluetooth Off.
    You can also turn off Bluetooth or Airport from System Preferences:

    From the Apple () menu, choose System Preferences.
    From the View menu, choose Bluetooth or Network to open the appropriate System Preference pane.
