In my experience (because of my work I have macbooks, linux machines and a windows machine), linux with i3 beats mac os x and windows on battery life by a (very) large margin; in some cases 3x (for instance on x220 2011 with 9 cell, I get 4 hrs under windows and 15 under linux/i3) with the same workload. Obviously I run the Linux battery tools, but so do the other OSs their own.
i3 here is the ‘magic’ part because with other, more mac/windows like window managers, the battery life is comparable, however, I cannot turn those off on mac/win so I cannot test if that is really the case. But if I use, say, unity, the battery life drops to at or below what it does with it’s native system.

And battery issues?

And issues of not being able to run software (often from Adobe) that are required for work.
And issues of not being allowed to run software for "security" reasons.
MacBook Pros definitely don't have a great battery life.
