Battery drain faster after snow leopard update?

[Baudolino]

Hi there!

I'm a happy owner of a MBP 2010, 15" i5, 2.4GHz.

Before some days I noticed that Snow Leopard installed its update 10.6.4.

Well no big problem but I have a sense that the time remaining without using AC adapter has slightly fell. Before, using only firefox for example I could see about 6 hours remaining (some minutes after powering on my mac). Now it hardly shows about 4+.

Has any other noticed that?
