    I have recently purchased the Refurb Alum Macbook 2.0GHz and I was wondering if my battery was abnormal...

    I left it in "Sleep" mode for like 1 hour and when I came back to check on it, the battery % was dropped from 78% to 72%.

    Is that normal ?? I should let you know that I had Wifi connection on, and had firefox browser open when I made it to go to sleep.

    Thanks for your time to answer ;)

    6% battery drain in one hour while sleeping doesn't seem right.
    Hell my iBook needed less than that for a whole day's sleep.

    There seems to be an issue with the new Unibody batteries, as there are a lot of cases where new MBPs use up to 3% per hour sleep.
    There is also a lengthy thread over at Apple Discussions in the MBP battery section.

    Yeah, that doesn't sound right... 6% in 1 hour?

    It should be 1% every 1-2 hours, or at least, that's what I've been getting.

    So... should I call apple ?? I am not sure if my Refurb Macbook is normal... or not... this is my first mac so I am quite hesitated about making the right call...


    edit: I think I am going to test my battery drain while in sleep again tonight... If I get the same result of 6~7% per hour then I will make a call to Apple tomorrow.

    Yeah, my macbook is my first mac too, but I have done quite a bit of research and all so I kinda know my way around "problems." I haven't had any with my macbook until a couple weeks ago, where my magsafe light won't turn on/charge. It's working ok now, but randomly it will decide to not work.

    But yeah, good idea on testing it again...do you have anything connected to the macbook? Bluetooth devices, ipods, anything? Those suck battery life as well no matter what.

    I just tested for 1 hour sleep of battery drain and it went down from 67% to 57% when I opened the lid to check it....
    This really worries me now... Anybody knows what do to here??:mad:

    Nothing what so ever... I even closed all the apps for this test and it resulted worse... What should I do? Is there a way to reset the battery? I have done the Battery calibration couple of times already the day I got it. I wasn't meaning to calibrate two times but the battery just ran out quickly and I didn't plug in while I was using...

    Edit: This Refurb Alum Macbook 2.0GHz arrived on Last Friday morning Jan 30th... And I purchased it online on the 27th... This is very frustrating..

    I guess the only thing that I can really say is make a Genius Bar appointment and see if you can get it replaced.

    This is Really disappointing.... I researched it quite a bit and trusted the Refurb products as I found some good feedbacks and reviews...

    So do I have to call the Apple Customer Service or... sorry its my first mac...:confused:

    Lol, as much as I really want to help, my macbook is my first mac too.

    Do you have an Apple Store near you? You can just go to the Apple site and schedule an appointment there.

    Where in Canada do you live? My closest Apple Store is the same distance as you. And it's not just because it is a Refurb, I've read about people with brand new machines and this same thing happened to them too, so you can't really blame it on that. Batteries themselves are never 100% consistent, so pretty much everyone's battery will be different in a sense.

    And I'm just glad I am able to help, I mean, I hate when people on these forums just keep saying "use the search" or "there are a ton of threads already about this". While those are true and might save you time, it's just...well, even more of a waste of time.

    I use the sleep function all the time and I use it when I go to bed, after about 8 hours of sleep, it'll have gone down about 5-8%

    Oh, and when you do go to the Apple Store, keep us (mainly me :) ) posted, I would really like to know the outcome.

    Just thought I would chime in to make you feel better about your refurb... I have a new unibody macbook and have the same sleep battery issue. This is my first mac so I thought it was normal until I saw this thread. I'll check with some of my macbook using friends and see how their batteries hold up. Keep us posted with what customer service says about it:)

    Yeah you were unlucky and got a lemon. That much battery drain during sleep is not normal. You should expect about 1% per hour of battery drain on a normal machine. Make sure you get yours fixed with Applecare.

    The rule of thumb that I use is that sleep power usage should be < 1%/hr. Anything more than that and I know that the machine's either got a bum battery or isn't sleeping properly. I've never actually measured power drain (and the software percentage reading is just estimation anyways), but the rough 1%/hr rule's a pretty conservative one that has served me well in the past.
