    I am new (sort of) to owning a Mac, I bought my macbook pro a couple days ago, so far I havent used it much for other than surfing the net. My question is regarding the Battery time remaining indicator, first of all it changes alot, so i never truly know how much time I have left. Is this normal? It can say anywhere from 3-6 hours left when I am at 90% battery. Usually at 90% battery it says I have about 4.5 - 5 hour left. I thought I was supposed to get up to ten hours of battery? The percent indicator seems to go down fairly fast like 1% every few minutes. Is this Normal? Should I take my macbook over to the apple store to be checked out?

    What are you doing on the machine when you see the difference in battery life?

    As I said, it can and will fluctuate, even when just browsing the net. Why? Because Flash is a CPU hog thus visiting Flash sites increase your CPU usage and that increases the power draw resulting shorter battery life.

    ...and when you stop browsing flash intensive sites your Mac recalculates the amount of time based on what you are doing at that particular time.
