    Hi! First of the "batt," here's the info:

    I've had my MBP since October and I am pretty shocked at the decrease in battery life. I never leave it plugged in except to charge. I need to have it have at least 3 hours of battery life for my classes. *Sigh*

    I'm going to take it to the Apple specialists at my Uni. Do you think they'll replace it?

    Should I leave it plugged in more often? I try to calibrate it once a month, should I do it more often?

    Thanks!

    yes, you definitely need to leave it plugged in as much as possible, just bring your charger with you with your laptop bag, and where you work, look for a plug first
    As for the replacement, they may or they may not
    Just make sure to cycle the battery completely at least once a month

    If it is under a year old they will replace it.

    i totally disagree. i discharge and charge my battery at least once a day, sometimes twice a day. i did this on my old laptop for 5 years, and the battery capacity was still about 85-90% at the end of that time. my previous macbook, which i had for almost exactly 1 year, i followed the same procedure and the battery capacity went UP a few percent. make sure then when u charge and discharge you do a full cycle whenever possible. i am pretty anal about it and it has served me well.

    by the way, they should replace it. been under a year and 300 cycles. i bet it was just defective based on your explanation of use.

    he is over 200 cycles and I doubt apple will do anything. Hell, I am having a hard time trying to get them to replace a 6 month old battery that was a replacement for a defective battery which has 38 cycles and 5% health (about 8 minutes of useage on battery power).

    The wording on apples battery page says you should be able to get UP TO 300 cycles and 80% health not that if you don't its defective. You can try, but I have a feeling its going to be an uphill battle.

    I hear both things -- always have it plugged in, or try to not leave it plugged in. Ugh.

    Thankfully, they took it in and will replace it. Good old campus computer services. :)

    I believe the book that came with my MBP or a Genius told me to drain it down to like 60% if you wont be using it for an extended period of time. You shouldn't leave the battery in there all the time though, doing that killed my first battery, but I was under warranty so Apple gave me another. My battery went from 3 1/2 hours to 20 minutes in less than a year leaving it in.

    Do you mean draining it to 60% and removing it from the computer?

    Yeah that's what I mean.. though it could have been 30%... I don't know why I can't remember and my books aren't at school for me to look at. I'm sure Apple's site has better information on it.
