Find What App(s) Are Using & Draining Battery on MacBook
Batteries on the MacBook Pro, MacBook, and MacBook Air are made to offer many hours of work on a single charge. Unfortunately, sometimes apps get in the way of our wonderful Mac battery life, often without a user even noticing until suddenly their battery life has been drained dramatically. The good news is it doesn’t have to be that way, because OS X provides a very easy way to see exactly what’s using battery (well, energy), which you can then take whatever action is necessary to resolve.
