Daniel Holm, if you boot into a 3.19.x kernel is this still
reproducible?

Title:
  Decreased battery life after upgrade.

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  In Ubuntu 15.04 I had around 7-8 hours of battery life but after
  upgrade I got half. Why? Maybe not the right package, but I don't know
  what else than the kernel. If wrong please change.

  I use lmt for increased battery life, and it is still installed (even
  reinstalled and I also tried ltp instead, but no change).

  Disabling intel p state turbo does no change. I dont really have any
  processes ruining it and it even says 4 hours after first boot.

  The battery ost 5% just while I submitted this bug report.
