add pcie_aspm=force i915.i915_enable_rc6=1 to  GRUB_CMDLINE_LINUX_DEFAULT
in /etc/default/grub
then run
sudo updat-grub

restart
you will get your battery life back
but there is a catch, it will affect your graphic capabilities a little bit.
i didnt try latest kernel, so cant comment on that.

Have you tried updating to the latest kernel? There used to be some 
Linux kernel regression that caused higher power usage. If I remember 
right, it will be fully fixed in a future release only.
