10.5.1 is killing my PB battery!

[giomla]

Since I installed 10.5.1 I have this weird problem... When I'm running my 12''PB on batteries and percentage falls to 20%, after a minute or two computers just suddenly falls asleep. Then when I plug in the power cord it seems like the battery was empty and starts recharging from zero. I know battery is not a problem cause just couple of days ago (with 10.5.0) it worked perfectly well (aprox 2.5hours).
In 10.4 though it lasted over 3 hours!
Anyone with similar problem?

I've noticed that I'm getting around 3 hours on my MacBook now. Luckily I qualify for the Battery Replacement Program, I was trying to figure out if it was Leopard or me just noticing how low my battery life is. If you are over 250 cycle/ battery over 12 months old, you will see a sharp decrease in battery life. Is this the case?
