    Are there any cases with 13 inch MacBook Pros losing battery life after the Lion upgrade? All I am hearing is from the 15 inch MacBook Pros.

    I have the 2011 MBP 13", and i've actually seen increased battery life since installing lion. While using Snow Leopard i was getting between 6 and 6.5 hours. However, yesterday, just through surfing the web, Xcode and iTunes, i was able to squeeze 8 hours 34 minutes from the battery. Sure to say i was impressed.

    Note. Brightness was about 60%

    Mid-2009 here and I think I've lost some battery life. At least the estimates seem to be lower than before.
