    Specs:
    MacBook 2.0GHz, Intel Core 2 Duo, 2GB DDR2 Memory, 120 GB hard drive
    Battery life...case...heat...plastic vs. aluminum?
    I've had my Macbook since 3/11 and it seems like the battery life fluctuates. Is this normal? Does my Macbook case trap the heat and my keyboard cover, which therefore decreases my battery life? Are the plastic Macbooks not as good as the new uni-body ones when it comes to heat flow and battery life?

    Describe in details what you mean by "fluctuate" please.

    My MacBook fluctuates in battery life also depending on what I'm doing.

    Watching something online versus being on a website. I always see my battery time going up and down. Aren't Macbooks supposed to have a battery life of 4-5 from a full charge? It seems like it starts in the 3 range...

    Specs:
    15" MBP '06 2.33 C2D 4GB 10.7; 13" MBA '14 1.8 i7 8GB 10.11; 21" iMac '13 2.9 i5 8GB 10.11; 6S
    The fluctuation of reported battery time remaining is normal.

    This is an estimated time and is derived from what you are currently doing and the processes which are running.

    The more processor and graphics intensive the application(s) you are using, the faster the battery charge will be consumed.

    You can't expect the same battery life while watching video or playing a game as you might achieve while working with a text document.

    Having airport and/or bluetooth running will use the battery faster than having them turned off.

    Etc.
    I cannot be held responsible for the things that come out of my mouth.

    Specs:
    Late 2013 rMBP, i7, 750m gpu, OSX versions 10.9.3, 10.10
    What bobtomay said + most of those battery life tests/reports are done with the most miserly settings to stretch the runtime. ie: reduced brightness, doing non-processor intensive operations, wifi and/or bluetooth off.

    Here's a good faq you might want to check out:

    What is the MacBook battery life in "real-world" tests? How does the battery life of different MacBook models compare to one another? @ EveryMac.com

    in the first real paragraph of the article, it mentions that using wifi drops the average battery life considerably.

    You're watching something online is using battery fast on two levels - processor work to display a video (data streamed in has to be assembled and displayed as a video) and your network connection (assumed to be wifi).
    My Macs: Late 2013 rMBP w/ 750m, 16Gig ram; 2013 Mac Pro 6 core w/ D700, 16Gig Ram; Mac mini G4, 1.25 GHz, 512m ram (server); Late 2011 11" MBA, 1.8GHz i7, 4Gig Ram, 256Gig SSD, HD3000; Powerbook 12" G4 1.33GHz running Linux; Apple TV (1080p version)

    I'm sure this has been written
    Do any of you hate the battery life from a full charge? What has Apple done in the past up until now with this situation? Do you know if there are going to be positive changes with this in the near future?

    If you're unhappy with the battery life of your MacBook, buy the latest 17" MacBook Pro unibody with the new non removable battery which Apple says lasts 8 hours..... Link

    Yea...because Apple notebooks have crap battery life compared to the majority of other brands. I suggest you sort out your charge and discharge cycle and stop posting hate threads which are completely pointless.

    I'm not sure what you're talking about. The two Apple notebooks I've owned have both had comparable or longer battery lives than the notebooks of pretty much everyone else with whom I work. Maybe you should try turning off features you know you won't use, like Bluetooth or even Airport if you don't need the Internet.

    Donno, the battery life on my 08 mbp is pretty much identical to the battery life on my 08 T61p (WITH the extended life battery).

    My early '08 MacBook Pro does about 4 hours on a full charge. That's pretty decent in my experience for a notebook of this class.
    Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

    People who feel Mac Notebooks have bad battery life compared to all the PC Notebooks out there should read Anandtechs test on Notebook battery life. Makes the PC Notebooks look pretty bad.

    My MB has fantastic battery life. I cab get between 4 and 5 hours depending on what I am doing.

    Are you experiencing problems?
