    I got my i5 15 incher when they came out and like many people was disappointed by the battery life. It was decent though and I said hey, 6 hours is great! Recently though I've been getting 3 and my usage hasn't changed at all. I mostly use my computer for chrome (rarely flash), mail, and itunes.

    I called Apple and the guy I spoke with wasn't the most knowledgeable person but he suggested that I reset the System Management Controller. I did that and now it looks like I'm getting 5-6 hours again! Hooray lol.

    Anyway I had to register and tell you guys. I hope this helps people out.

    I'll have to give that a try.

    What is the difference between resetting the SMC and PRAM?

    how do u reset the smc ?

    i tried to recreate apple's perfect conditions to get the advertised 8-9 hours of battery life, but i can never reach 8 or even 7 hours.
    the most i can get is probably 5-6 hours. i already calibrated and all that. is this normal??

    I also don't understand how in some test they got 11 something hours on idle.
    The best it ever showed me was something around 9+ hours wenn everything is off. It is arround 4-5 h with higher brightness and 5-7 with low brightness when doing nothing aside from a little typing and browsing non Flash websites. Intel only mode off course.
    Anandtech got significantly better results.
    Today it was exceptionally bad but than I found that although I quite chrome the divx web player plug in process of Chrome was still running and constanly using about 2-3 % of CPU Power, enough to prevent deeper sleep states.
    The whole estimate is odd. I am at 60% now and it says 4:30h with about 50% brightness.
