    I have a 2011 11 inch macbook air that i bought brand new off of someone from kijiji.

    I recently noticed battery life was low so i ran a couple of tests

    When i use my macbook air at 3/4 brightness i can charge it within 1 hour and 30 mins

    but the full charge only lasts for about 3hours and 10 mins

    this is doing web browsing / flash videos

    These are the power saving settings i use when i'm on battery

    Computer sleep: 1.5 mins

    Display sleep: 1 min

    so is there anything wrong with my air?

    No, that seems about right. The battery on this thing is pretty bad.

    Seems about right. But 3/4 brightness is "bright".

    i typically use it mobile with 2nd lowest bars. turn the keyb oard backlight off, and turn off Bluetooth.

    Easily pull out 4-5 hours. sat down last night at 6:30 with 60% charge, and watched the entirety of the leaf hockey game till 10pm and still had 30% charge when done.

    its about how you use it. if you're on a flash heavy site that is constantly streaming data, you'll chew through battery in no time.

    That sounds is rated for 5 hours at 50% brightness. 3/4 is very bright! I usually have it at about 2 bars on battery and cranked on power. I've not had it die on me, but I'm typically only in 1 hour meetings at a time.
