Public bug reported:
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.
