Yup, completely. It's a really nasty problem too because power usage isn't linear. Chips tend to have voltage steps[1] as they increase in frequency so if you can do something longer and at lower frequency it uses less power than the same workload at a higher frequency for shorter time. Compound that with the fact that you really want to bring the whole SoC to a low power state and just keep the display lit since 90% of the time users aren't actually moving something. Arm has tried to solve this with big.LITTLE[2] to mixed results. It turns out that it's hard to build a general purpose scheduler that's power aware much like it's hard to build a general purpose memory allocator that's fast in every case.
