    My Biology class was 1.5 hours and I had less than 20% on my new MBP to type notes in a class where the teacher tests on what she says and talks very quickly. The MBP said 20% = 2 hours w/o wi-fi. I couldn't believe it, and I can lift it with 2 fingers, it's the perfect college laptop (besides a netbook, which isn't all that powerful)! Do you guys think that the battery is definitely a big selling point of the MBP? That was one of the biggest reasons I bought it and it's serving its purpose!

    I have the same thoughts on the mbp's (new ones). For college battery life is critical while you are "in class."

    They are also very powerful machines and they look beautiful. I have a early 09 one (same as the june 09 unibody mbp's except without the 7 hour battery, only a 5 hour one).

    I frequently get that 5 hour rating as well which is awesome and definately worth it since a typical day at university for me is almost 6 hours long, and counting the times I put this to sleep and dim the display, I easily make that without ever having to plug this thing in.

    Glad you like it :D I love mine :)

    Yup. Definitely. This battery's epicly awesome:D. Couldn't ask for better;). Watched 5 hrs of DVDs on the plane a couple weeks ago.:rolleyes:

    Epic.

    Just imagine. In 20 years, we'll have even longer life batteries:eek:, like, 24 hrs or something:D

    The batteries themselves are nice, but it's also due to the high energy efficiency of the MBPs. LED backlighting, ddr3 ram, and the 9400 chipset... etc. sip on power compared to cheap hardware used in acers and HPs, that's why they only get 2 hours tops out of 6 cells.

    Even on my small 50Wh late 2008, i can get 5.5 hours if I'm careful. Not that I need to be because most of my classes have power outlets in the seats/desks. :p

    I'd say power will be wireless in 5 years, and by twenty years if not ten engineers will be able to create perpetual laptops with the battery powering some sort of alternator/generator on the fly.

    Laws of the universe

    Wouldn't that break the 2nd law of thermodynamics?

    Don't you remember the Simpsons!!!!! Even Homer respects the 2nd law of thermodynamics

    Touch
    Gen. 1 MBP
    3 MB's
    PB 15" 1.67
    newest gen. Nano
    1st, 2nd, 3rd Gen. Ipod
    Wallstreet PB
    borderline - 2 MBA's
    Sure there's a couple more but it's late here....:eek:

    Yes. You can't get more energy out than you put in.

    do the batteries last longer? I know they have longer runtimes b/c it's simply a bigger battery, but can they be recharged 1000 times? are your capacities dwindling at 1/3 the rate of a normal battery?

    I LOVE my MBP's battery. I'm only in High school, but i find myself constantly at the library or out of the house, and i almost never have to carry around the charger. Then at home i can just sit back anywhere and not worry about the battery.

    Probably one of my top 3 favorite things about this.

    I think its better than any other battery in a laptop comparable to this one, but i cant say im amazed... i have never gotten 7 hours out of it, and most of the time its more like 5... so i cant complain because 5 is still great, but i wish it got the 7 they advertise... and i have tried several different tricks and types of usage to get to 7 hours.. unsuccessfully.

    Even last year's MBP batterys and the ones before that were pretty decent. You could eerk out 4 hours of notetaking with some minimalistic techniuqes.
