7 hours is the MAX. The actual battery time will depend on many things. I've personally never seen a 7 hour run time, and doubt I ever will.

Actually, let's go straight to the source on this one:
apple.com/macbook-pro
Says here UP TO seven hours, and says it comes by that figure: "Wireless web testing conducted by Apple in May 2012 using preproduction 2.6GHz quad-core Intel Core i7–based 15-inch MacBook Pro units and preproduction 2.9GHz dual-core Intel Core i7–based 13-inch MacBook Pro units. The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 50%. Battery life varies by use and configuration. See Apple - Batteries for more information."
So there's your answer, Retake. You can get better than 4.5 hours, but it depends VERY heavily on what you're doing, what services you have turned on (for example: using Bluetooth? No? Turn it off.) and what screen brightness you have set (mine is NEVER above 50 percent and frequently below that). In the test, a MBP that was just wirelessly websurfing at 50 percent brightness got seven hours. If you have the time, why not try to replicate the test (you could probably use a script -- or an intern -- to mindlessly surf all day for you).

I too have a brand new 2 day old macbook pro 13" i7. fully charged, i unplugged it at 7:45pm, it's now 10:00pm and i'm at 15%! brightness is at or below 50% and i've been doing basic web browsing and itunes. starting to think i have a defective macbook here. 3 hours on battery?!

As I mentioned above, make sure you're not running things in the background that you're not aware of, turn off Bluetooth if you are not using it, and try just doing the surfing (no iTunes, and no Flash websites) from a FULLY charged state (hint: the moment the battery hits "100%" is not the same thing as fully-charged. Try an overnight charge.)
Report back and let us know how that went. If you got a lot closer to seven hours, then we have an answer. If you got closer to three hours, then I'd say yes, the battery is defective.
