When Apple rolled out Mac OS X 10.8 Mountain Lion, the company claimed the operating system introduced over 200 new features to the Mac platform, but reduced battery life wasn't supposed to be one of them. Nevertheless, a large number of users have taken to Apple's support forum to complain about major dips in battery life after installing Mountain Lion.

"I upgraded to Mountain Lion and now my battery life is about half of what it was before upgrading," the opening post reads.

Others quickly chimed in with the same complaint. One Mac user said he used to "easily" get a full day of use on his 13-inch MacBook Pro before the battery would give up the ghost, but with Mountain Lion installed, he's down to 5 percent remaining halfway through the day and with "less than normal" usage.

There are several theories floating around in Apple's support forum as to why this is happening, but no clear cut answer. In the meantime, Apple is aware of the complaints and is in the process of contacting affected customers to gather data and, hopefully for them, root out the cause so the company can fix it.

Like I've said for a bit now winding down Apple dominance bit by bit.

yep too bad they have been experiencing this ...some Mac users seem to feel as frustrated as the the mountain lion image in the post .. maybe best for them to focus on the products rather than the patents [etc] and keep the Mountain Lion folks happy campers.Either way the folks with the ca$h may seek the advice from the Apple store pro's and fix it.

It's odd, because you would expect battery life to be great with Lion, since most batteries are Li-ion.  Maybe the missing 'i' in the OS name is causing compatibility issues.

What part of "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn" don't you understand?
