    Dual-core is more battery efficient

    For those interested in the multi-core argument on phones/tablets the below is worth a read:
    -----
    It should make sense by now why having multiple cores sharing the same workload would be a more efficient means of processing tasks on your phone. Not only does this make multitasking much less of a nightmare, it adds to your total battery life. A 1GHz dual-core chip (where both cores are 1GHz each) that splits up the assigned tasks would only need to run at half its maximum clocking speed; the reduced speed of each core will result in the same -- if not slightly better -- performance and lower power requirements. Lower frequencies result in less mandated voltage, and the consequential reduction of power is reduced by the square of the voltage decrease.
