    Let it drain to about 94% and then charge it again - it will fully charge to 100% after.

    This is just Apple's way of minimizing the cycling of the battery. Call it an allowance, if you will.

    It always reads fully charged when at 95%.

    and the other issue is that now that it drains a little, it seems to drain pretty fast. It 10 minutes of internet surfing it has gone from 100% to 90%. Is this normal? Screen is on lowest brightness and no video is playing. Just surfing these forums, no other apps open. I am on wifi.

    Are you guys talking about the battery health or charge? Mine since i got it never got over 96% in battery health but i get 100 % charge .

    At the beginning i was worried with this battery health thing but then i called apple care and read in this forum that it s normal. Eventhough i would prefer it to be at 100%

    I've had my refurb MBA 11.6 now for about two weeks. I've calibrated my battery twice in that time (run on battery until the MBA shuts down, let it sit for 6+ hours and then charge it completely) and my battery had never gotten above 98% when fully charged.

    I realize it is just being nit-picky, but I would like it to reach 100% as well when fully charged. I will try juro's recommendation above and see if that works for me.

    It's working as designed. Note the section on CHARGING in the following link.

    This should answer most, if not all, of your battery questions: Apple Notebook Battery FAQ
