If your MacBook battery life is draining quickly, check to make sure you didn't leave an iTunes Store page open, warns Kirk McElhearn.

Lest you think that a lot of the CPU that iTunes is using is to play that Allman Brothers song, here’s what happens if I switch out of the iTunes Store. Together, iTunes and coreaudiod, which processes audio played by iTunes or other apps, use about 7% of CPU.

Troll days are over! Apple would have to be completely braindead to give up like that, but what are the odds after the effort they are still putting effort into compared to past versions? iOS 9 has done some serious work even by ram standards.
