Ars Technica reported earlier this month that OS X Mountain Lion is draining notebook batteries faster than it should, decreasing battery life by 38%. For what it’s worth, I have first hand experience with this problem.
Now Softpedia reports that one developer claims that OS X 10.8.1, a build that is currently in developer testing, addresses the issue. This individual claims that battery life is back up to where it was before installing Mountain Lion. Apple’s own discussion forums seem to back this statement up at the moment as well.
Just as I have been sitting writing this post, in a span of minutes, I have watched my battery life indicator in the Menu bar drop from 70% when I opened the lid, to 64% by the time I finished typing. Before Mountain Lion a single charge would safely last all day. Regardless, it seems that help in on the way with OS X 10.8.1.
Are you experiencing battery problems under Mountain Lion as well? How bad is the drop in charge? Leave a comment and let us know.
