    Say I do the exact same amount of computations. Obviously the 2.9 GHz will get them done 7% or so faster but will it also use more battery in the process?

    I don't know for sure, but I think even if there is any difference, it will be marginal.

    2.9g consumes more power, but runs shorter before returning to idle....

    Same battery life 100%. The CPUs both run at extremely varying frequencies from 800mhz to 2.9ghz and up to their boost clock depending on the load. For battery-light tasks both CPUs are likely at very similar frequencies. Same applies for Pro 450/455/460. Identical battery life.
