I haven't seen much difference between Macs and other laptops. My current MBP 13" (non-Retina) lasts for about 5 hours when doing normal dev work (text editing, compiling, debugging), I would consider this "light use". This is similar to the Dells, Sonys and Lenovo's I had before or currently use. One difference I see is that battery life doesn't seem to degrade as quickly as on other laptops I owned a few years ago.

I don't have "cross-platform" experience with phones, but my iPhone4 running iOS7 is pretty much drained after a normal day's use (it was better with iOS6).

All "anectodical evidence" of course ;)

The MacBook Pro Retinas and MacBook airs take advantage of newer battery cells, and have greatly improved battery life in my experience. The 13" MBP battery never impressed me.

Also, not sure when you bought your particular iPhone, but the iPhone 4 is coming up on being 4 years old (announced round about the same time as the Galaxy S for comparisons sake) and it's still able to last a full day with the latest software, and all on single core processor. I find that really impressive, to say the least :)
