[Bug 1513886] Re: Decreased battery life after upgrade.
The battery does seem to still have more battery life than stated by the
indicator and acpi command. Used for aroung five hours now and 23% left.
Turbo turned off and powersave governor. Maybe the bug is in the
reading?
But why is the turbo mode enabled and the cpu running on full speed as
default?
Also I'm no longer able to play HD video. Connected?

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.
