    been using my mba for a few weeks now and i noticed that even when fully charged and still pulled into the charged the battery percentage still says 99% i have yet to see it reach and stay at 100% while being plugged in. is this normal? i am on my 5th cycle if that matters.

    thanks

    This happens to my MB as well. It is normal.

    You can unplug your charger and let the battery go to 95% without using a battery cycle. Then plug it back in and it will go to 100%.

    This is normal. I've seen mine fully charged and yet at only 97% don't worry. Also, the battery readings will stabilize as you get more charge cycles in there. Early on, I think it's important for the battery health that you calibrate it, and also avoid half charging it etc. Just for the first little while!
