    Does any of your macbook airs take super long to recharge? Mine was at 33% and it took almost 6hrs. I already tried to re-calibrate the battery and did the PMU reset thingy

    Mine charges relatively quickly to about 75% then slows way way down

    That is the normal behavior. It fast charges to around 80% and then trickles to 100%.

    To the OP: Slow charging is a known issue with the MBA, read around this forum. After a few charges it should start charging in a normal amount of time.

    Takes me about 2.5 hours from 10% to 80%.
    From 80% to fully recharged is another 2.5 hours.

    First charge for me was 7 hours, however after doing 2 complete charges/discharges it now charges to 80% in 2 hours, then trickle charges the rest over 1.5 hours.

    Spoke to Apple over the weekend, i was told the long first charges are expected behaviour until the battery is correctly calibrated.

    I just got the air today, and the first charge (after I drained it) is taking 8 hrs around. Should I just wait it out and the solution will find itself or do I need to do something? THanks.

    give 2-3 full charges and it should get shorter. mine now takes 2.5-3 hrs to recharge. But my first few where 8-9 hrs. I actually returned my macbook air for this reason before i found out that it would get better in time. So after finding this out I went back to the store to get my macbook air back. Happy I did I love this thing.:D

    Thanks! It says 3 hrs left and it's at like 60%...

    So you're saying the problem will just go away on its own after I discharge/charge a few times? 3 hrs is fine.

    And what about the clicking sound...is that normal? I frequently hear quiet clicks...is it normal for this kind of HD? Not terribly annoying, but it's more noticeable than in my old MBP.

    thanks for the advice!

    My first full charge took a little over 8 hours. I ran the battery all the way down to the point where they system shut itself down.

    Since it sounds like this is "normal" behavior I won't worry about it at this point. So far, I am loving this thing.

    Knock on wood, but my MBA sits flat, doesn't click and the backlit keyboard seems to be working properly. Maybe I lucked out :)

    I had the same problem. After 15 charge cycles, it was still taking 7 to 8 hours to charge. I tried to COPS routine at least 3 times. Finally, I took it to the Genius Bar and they replaced the unit. My new MacBook Air charges in 3.5 to 4 hours right out of the box. I'm happy I switched it out!

    I'm so frustrated with apple stuff already. everything I buy from them has SOME sort of defect. It seems like mine is busted, according to istat pro ive actually been thru 6 charge cycles and now its at 33% with 6.5 hrs to completion.

    Damn, i'm frustrated. Now i have to format the computer, pack it up, go back to the store, and hope to win the apple lottery this time....
