It is also thought that the update will improve battery life. Owners of MacBooks, MacBook Pros and MacBook Airs began reporting battery life issues shortly after Mountain Lion launched on 25 July. According to user reports, battery consumption is considerably faster than before the upgrade to Mountain Lion, with a resulting shorter battery lifespan.
