I've been debating on whether or not I should take my computer into the Apple store. I feel like the battery drains too quickly. At the moment I only have Chrome, 1Password, iMessage, iPhoto and iTunes running. In Chrome I have 3 tabs open, Facebook, MacRumors and YouTube. I have the screen brightness to all but 5 of the little squares and the backlit keyboard to only 5 squares. I also usually have Airmail running with push notifications. I unplugged it from full charge about 30 minutes ago and the battery indicator changes from 3:30hrs left to 4:15hrs left to 3:05hrs left etc. It's at 88% now. Does this seem like normal behavior from a pretty new battery? I bought it in December of last year.
