Unibody Macbook Pro battery life 2.66 versus 2.93 ghz

Is there any battery life difference between the two speed of processors for 17 inch MBP unibody? I would be interested in the higher speed but not at the expense of battery life.

no there isnt. you talking about a 270mhz difference which is maybe a .01 watt difference if that..
 
Yeah, there is probably a tiny difference that doesn't really make a dent in the battery life. The only disadvantage of the faster processor would be the added heat, and even that is not noticeable.
 
Some people even would even argue that it would be longer due to the fact that it can do its processes faster, therefore it wouldn't be used as much.

umm i dont know about that.

Theoretically there's logic in that, if you were to do a fixed amount of work on both machines, if the 2.93GHz is running at the same voltage etc, then if it's able to complete the workload faster then it is going to be sitting idle more, and when it's idle it goes into a low power state to conserve energy.

Whether that translates to anything in real world usage is anyones guess though...

haha yea i hear ya. but like you said i think dont think there is a noticeable difference in the real world

It may be theoretically logical, and even if its true, it would only be effective if one was to shut off the machine as soon as the task is completed, which we know doesn't really happen in real life. Theories don't always translate to real world. Kinda like saying if you can bench 300 Lbs 6 times, then you should be able to bench 600 Lbs 3 times which isn't the case.
