To be honest, in general it does improve battery life if you are faster. Battery life is a race to CPU sleep mode, and if you finish the job faster, the more energy you can save.

- kaba0 3y agoNot much runs persistently, more like periodically. And the amount of time it has to be running still matter — processors when turner on leak a bunch of energy no matter what.
- xhdueuchrv 3y agoI’m skeptical about this. Why would a faster processor in it of itself be more energy efficient at executing instructions?
- supertrope 3y agoA faster processor reduces execution time allowing the CPU to return to sleep status faster. Total energy used is power x time. While increasing operating frequency increases power quadratically due to P = CV^2, it is usually a net energy savings to let the frequency boost as high as a mass produced chip can go to minimize time spent in the highest power state. This assumes a finite bursty workload.
