    Hi there,

    I just bought my new MacBook yesterday and I haven't shut it off since then. However, after it became fully charged at 100%, the battery life has dropped down to 96% and not increased as it says the battery is currently fully charged.

    Any help would be great. Should I bring it back to the distributor, or... ?
    Thanks in advance.

    The batteries won't charge when reading 96%. I don't remember the specifics - someone will help me out there - but it's built that way.

    download coconutbattery to see if your battery lost some holding power.

    Right on! Let it get down to 94% or so if you want to fully charge back to 100%.

    Which puts undue wear on the battery.

    Ya it puts so much wear on the battery. :p

    Just to let you know once the battery gets to 95% and above it you unplug it and plug it back in, it will not charge.

    EDIT: Forgot to mention mac laptops have been like this for a while, at least the last gen macbooks before this also were like this.
