Use a single core at a time to save battery?
Is it possible to only use a single processor core at a time to save battery?

echo 0 >> /sys/devices/system/cpu/cpu0/online
echo 0 >> /sys/devices/system/cpu/cpu1/online
Only use one of them at a time...
Not sure if it would save power though.

Allegedly offline core drains more power than the idle one.

I found conservative governor best in terms of powersaving.
