    Hi
    I have a few qs about the battery. 13" 2010 model
    please dont tell me to read that battery article - I read it 10 times already.

    1- I am getting shown 3:40 left with Brightness 100%, Keylights 100%, 1 USB modem plugged in sucking 5W. Only safari open. is this acceptable? battery usage between 14 and 20W.. isnt that high for only safari and 1 usb device?

    2- My battery life was 96% from the day I got it, until a month ago. A week ago I noticed it went down to 89%. Yesterday I calibrated, and now its 91%.
    I know this is not extremely accurate, but is there anyway to set it to the real level?

    a- I recalibrated yesterday
    b- MBP was bought on Jan 28 2010 Brand New - NOT refurbished from apple. for some reason Coconut battery says that the computer is 7 months old. is this a problem?

    It was probably manufactured before the day you bought it ;)

    How many cycles do you have?

    I have a 2010 mbp and get significantly more life out of my battery than that.

    Apple Notebook Battery FAQ

    I recommend you re-read it, because you're not understanding the information it is giving you.

    Having all your lights at max level with a USB device drawing power is going to reduce your estimated time remaining, considerably, if you realize the estimates Apple gives for the battery is using considerably less than max for screen brightness and keyboard, with no USB devices attached.

    If you had read the FAQ, you would have found all of your answers.

    It's all normal. Coconut battery is often inaccurate.

    Completely acceptable for max brightness, backlight, and external device.
