Do 13 inch MacBook Pros lose battery life from Lion?

[TSE]

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.

Mid-2010 MBP 13''. I can say that i'm getting better battery life with lion. It is not a real big change but yeah i see it better know. (With almost a year of use my battery health its 88%)
