    My battery life is very bad. goes down 40% in half an hour just viewing the internet. Only one year old, still have warranty with Applecare. Will I be able to exchange it for a replacement, how does this work?

    Thank you all.

    It doesn't seem like there has been a huge capacity drop in your battery. That being said, I recommend repairing disk permissions via Disk Utility, resetting the PRAM and SMC, and calibrating your battery.

    Of course the information he will provide from his Mac will help, but it seems obvious that there is a problem with his battery. My sister has a 15" MBP from 2009 which I used from time to time before getting my own and it provided me with good 5-6 hours of web browsing and video streaming...

    They'll only replace it if there's something wrong with it; granted you haven't tripped any of their booby tra... I mean, sensors.

    Go ahead and pull up your Activity Monitor (in Utilities folder). Make sure there isn't anything consuming your CPU that you're unaware of.

    Have a look at Activity Monitor (Applications > Utilities) and select Show All Processes and sort by CPU to see what the culprit may be.

    Apple will replace it if it is under 300 cycles. However, since you're pretty close, they might not.

    Haven't they extended it to 1000 cycles in accordance to their promised 1000-cycles reliability with the new non-user-replaceable batteries?

    And OP:

    Have a look at Activity Monitor (Applications > Utilities) and select Show All Processes and sort by CPU to see what the culprit may be.

    And image as example is included in post #12.

    They might replace it - I'm not totally sure. The Genius didn't replace my battery when I went in (with under 300 cycles) because he didn't see any cause (even though battery life was horrible).


    Depends what MacBook Pro it is - which MacBook Pro is it?

    If it is less than a year old, it is one of the June 2009 editions, with the non-user-replaceable batteries.

    If they will replace it under 300 cycles, then they will replace his at 289.

    That's like saying "Yes Sir, you get a free 1 year warranty with this car... But it expires in 300 days."

    Have you actually tried running the battery down and physically timed how long it lasts? In my experience the % isn't always accurate, I've been at 0:00 remaining for over 30 minutes once.

    Post a screenshot of the processes window (How to: http://guides.macrumors.com/Taking_Screenshots_in_Mac_OS_X)

    No - it's really not...

    As the image shows, click on the PROCESSES drop-down menu and select ALL PROCESSES , then click the CPU column (the one I marked RED like the PROCESSES drop-down menu) to sort by CPU usage (descending). What does it say there?

    That is normal, unless there is a high profile process. We'll see, but it seems to be non-CPU related.

    Even though the screenshot is kind of wrong (you sorted ascending and scrolled down a bit, so no CPU intensive processes might be seen), it still shows, that there is no connection between CPU and battery power. Make a Genius Bar appointment or contact Apple otherwise to get them to do something.

    Btw, did you try an SMC reset and calibration of the battery like previously asked (but not answered) or used Coconut Battery to confirm the battery's health?
