    Not sure if this exists in OS X or in the Apple world... lol

    My MacBook Pro is coming in tomorrow hopefully from a super long wait over the weekend (sad).

    Now, just curious that I am not sure if the power theory is the same as PC.

    We all know that Windows has Power Save mode and Performance mode. It will throttle the CPU or GPU down for more battery saving while running on battery only.

    Since MacBook series has switchable graphic and such. There is no such things as power saving mode or performance mode.

    Plug in AC for full power.
    Less performance while running on Battery.

    My question is; MacBook just runs as if there's AC or not the same power level. Just like iPhone / iPod Touch?


    I'm asking because I'm lazy to keep finding power jack around in University in order to do intensive 3D animation or video editing. If the MacBook will just run as full power if needed while on battery. I'll be happy.

    In the past with macs, when on battery performance would be limited.
    I don't know if they continued it onto the newer models, haven't had a chance to test out mine yet.

    They don't do it anymore.

    I play Starcraft II on battery mode all the time. It's the same performance as when I'm plugged in at home.

    Thanks for the information guys. I'll be happy to work on battery performance then instead of wasting time chasing power jacks.

    Don't expect the battery life to be very long while doing these kinds of things...

    Even gaming doesn't suck back this much power.

    yeah, i don't know how much "intensive 3d animation" you do, but from my experience, i would not want to be doing that on the battery and risk my renderer bugging out when the the battery dies after 30 seconds and not even 1 frame is done...

    When I'm at work, I have my MBP set to "Higher Performance" which enables the use of the 9600M video card. I also use this when I'm going to be playing games like Portal. When I'm on the couch, I have it set to "Better battery life", which uses the 9400M and also dims the screen a bit.

    ya....like everyone said, be VERY careful of your battery dieing.

    naturally, shut off all your other programs, make sure the vents aren't blocked, dim the screen as much as possible, and KEEP AN EYE on the battery levels.

    it'll warn you when low....

    it'll 'hibernate' when too low to try to prevent anything fro being lost.

    there are 3rd party apps you can use to choose your graphics and not have it auto switch.
