It seems like every time Apple releases a new version of iOS the battery life on iPhones would drop significantly. Now with a the newest version of OS X 10.8 Mountain Lion, some users are reporting a significant decrease in battery life on their MacBooks after they upgraded from Lion to Mountain Lion.
Our buddy Chris Foresman at Ars Technica looked into the issue and found that his new Retina MacBook Pro has lost about 38% of its battery capacity, which is pretty huge. Have you seen anything similar in your own use of Mountain Lion? What about any other bugs that Apple needs to fix immediately? We want to hear about it in the Cult of Mac Forums.
