The default is performance for boot speed, this gets switched to
Conservative after login and remains that way we do not leave you in
Performance mode unless there is another bug.

This is likely to increase not decrease your wakeups, as you have made
timers more granular and scheduling ticks more common. It is not clear
how this improves anything, in our testing it cost you 10% of additional
CPU to perform tasks which should equate to more heat.

Fair enough.
