Hi Joseph,
Sorry for the late response, I did not receive the notification for some
reason.
I did test at the time, with all latest 4.5.x, 4.6.x and 4.7.x kernels,
no change.
It would make sense to test with 4.8, or even better, wait for 4.9 and
test it with that?

Title:
Power usage 50% worse than 14.04 on MacBook Air 6,2
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi,
I do not know which package/condition to attribute this behaviour to,
but MBA running Ubuntu 14.04 is using about 50% of power that needs to
be delivered for 16.04. (minumum 10W power draw vs minimum ~5W draw).
Otherwise 16.04 works well.
Any clue how to tackle this?
Best,
b.
