What size MBP do you own? If it's a 15'' - 17'' that's the normal battery time, but if it's a 13'' it may be a sign of a malfunctioning battery.

I have the 2010 13" Macbook Pro - just bought it a few days ago.

RedJeans, have you completely drained the battery, like the guide says?
Yes, last night - and then didn't use it for 5 hours + (was about 9 hrs) and then plugged it in - just like it says in the guide.
So how much CPU is used then?
And have you recognized any jumping around in the remaining time that is given by the battery indicator?
