Other readers wanted to know if there would be a significant difference in battery life if the tests were run on a solid state system drive (SSD) versus a traditional hard disk system drive (HDD). In response to our reports, we received many questions and suggestions for further testing, with some readers telling us that they experienced a similar loss in battery life after the upgrade from 10.6 Snow Leopard to 10.7 Lion. We were able to demonstrate that the upgrade to OS X 10.8 Mountain Lion caused a significant reduction in battery life and that Mountain Lion’s first update, 10.8.1, only partially restored the lost running time. Last month we performed a series of battery life tests on three Mac laptops: a 2011 15-inch MacBook Pro, 2012 15-inch MacBook Pro with Retina Display, and a 2011 13-inch MacBook Air. We have put those builds through the same test and the results can be found here.
Update: The final builds of 10.8.2 and 10.7.5 were released by Apple on September 19.
