mpdecision is the proprietary service that changes the cpu clock and
enable/disable the other cpus, so that is just a side effect of others
taking more cpu processing.

Title:
  Extensive battery drain on RTM

Bug description:
  Mako, RTM 1

  Since upgrading to RTM the battery life is really poor. What used to
  be a battery drain of 5-10% per hour (which is still high) is now
  10-15% per hour. Sometimes the phone runs really hot, so there seem to
  be something going on in the background that is consuming power. I
  mostly have bluetooth, GPS (which isn't always working), wifi and
  cellular on, but that's no difference from when I was running 'devel-
  proposed' with MultiROM with much less battery consumption.

  As an example, I started with a full charge at 7am. After some web
  surfing (<15 mins) and watching a couple of youtube videos (on wifi)
  battery was down to 66% at 9:15. That's 34% in just over two hours! I
  recharged again before lunch and had the phone idle until coming back
  1 hour and 45 mins later to find only 75% of battery left, this time
  without the phone running particularly hot.
