    I have a Mid-2012 13" MBA 128GB//8GB, and the current cycle count is 166.

    For the past few week I've been using a lot of my MBA and for the past few days when I hit the battery icon on the top right section of my screen, the drop down says "Service Battery". Besides going to the Apple store to get this rectified, is there anything else I could do ? Also my battery runs only a max of 3 hours++ since the 'service battery' sign appeared.

    And I usually charge my MBA when the power is <20% and leave it on to 100% and don't discharge it until I switch my MBA off. Is this the correct way ? Or should I switch the power adapter off immediately when it hits 100%, use up the battery life until it hits less than 20% and charge it again.

    Thank you for taking the time to read this. Helpful answers would greatly be appreciated :)

    Okay I see.Your battery is under the 80% off the original capacity and there are two options:
    1.You can use your battery if there is no problem for you with 3 hours.
    2.Replace the battery with a new one on Amazon,Ebay,Ifixit or bring it to a Apple store and they will replace it!

    Bad idea. Not only could the capacity be very low however, it could be damaged/bulging.

    OP, keep using it for the next few days as the battery level can sometimes momentarily read incorrectly. If it stays that way for about a week, it's time to get it replaced.
