OS X 10.8.1 Shows Small Battery Life Improvements, Sometimes
Now that OS X 10.8.1 is here, has battery life really improved, as rumored? The Mac Observer did some tests, and the answer is… sometimes?
They found that a 2011 MacBook Pro got about 52 minutes more battery life under OS X 10.8.1 than it did under OS X 10.8, but that’s still 78 minutes (!) less than they got under OS X 10.7.4. Retina MacBook Pro battery life has actually degraded in OS X 10.8.1, though, dropping 13 minutes.
That might just be a fluke, but I have to admit, I haven’t noticed any battery improvements in OS X 10.8.1 on my 2012 MacBook Air. How about you?
