I'm kind of confused... how does reduced power consumption cost you battery life?
Is it because a given workload will take longer to complete, and therefore take more total power by the time its done?
If that's the case, then it's actually workload dependent. Specifically, I'm thinking of playing retro games that insist on taking 100% of the CPU. They needlessly waste power to achieve much greater that 60 fps, even with the CPU clocked to the lowest scaling frequency. Would PowerClamp not increase battery life in this scenario?
