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?

    with more than 10 years of experience as a software engineer, there’s no ‘somtimes’ word in the bug-fixing dictionary. ‘Sometimes’ means the root of the cause is still ambiguous so the mentioned test done by The Mac Observer is useless.

    The battery life on my iMac has stayed about the same ;)
