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
mike

Have you calibrated the battery?

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!
