    My RMBP battery life only seems to be 3hrs. I have every energy saving thing checked. I'm not sure if I'm doing something wrong or not. Could you guys please give me advice. I just got the mac yesterday, today is the first day I have used it off the charger and it's battery life has been horrible.

    ps this is not my first mac.

    I am a bit disappointed by my 3:30 battery life. Certainly better than my old Dell laptop, but nowhere near 7 hr estimate.

    I do realize 7 hrs is an optimal number, but 50% less (real world) seems like a wide gap. My last charge cycle I tried a few things:

    1. Brightness 50%
    2. No VM tasks
    3. No video
    4. Very light duty browsing, emails and such

    Battery Logger app reports:

    Start: 100%
    End: 2%
    Duration: 3:35:55
    Sleep: 63:41:30
    Off: 00:01:33

    Maybe my Mac was not really SLEEPING for the 64 hours I was away from home... ?
