How? I think ICT is useful to reduce power consumption and increase time working with battery. > If the idle state uses less power than the running state, then it is probably > better to run the instructions as quickly as possible, and then spend as much > time as possible in the idle state.

I look at /proc/pmu/battery_0, but unfortunately there are only values when running without power connection (discharge battery).
