I just got this 15 inch mbp, and on the apple website it says the battery lasts for about 8-9 hours, however when it is fully charged mine says about 4 1/2 hours of battery. Also I feel like while I'm on it it depletes pretty fast. Is this because of playing games and watching movies on it?

Yes.
Those estimates are on like 50% screen brightness, backlit keyboard off, and just browsing the web. The more you're doing, the faster you will kill your battery.

Also, wireless, bluetooth, etc will shorten the battery life.

Testing conducted by Apple in March 2010 using preproduction 2.66GHz Intel Core i7–based MacBook Pro units. Battery life depends on configuration and use. See Apple - Batteries for more information. The wireless productivity test measures battery life by wirelessly browsing various websites and editing text in a word processing document with display brightness set to 50%.

Actually I'm curious to know if this is a NEW 15" MBP ??
I just removed my Magsafe and it calculated into 6hrs 47Mins, Screen 2/3 brightness and keyboard on.

If your interested to see how healthy your battery is, in the image take particular notice of the yellow shaded area. If they are up where mine is and the Charge remaining (mAh): 5700 and the Full charge capacity (mAh): 5748 are within spitting distance of each other you dont have much to worry about.



You could also dl CoconutBattery and use this to monitor the battery health. This is a good App but dont always take it as gospel. Just use it as a reference

Cheers

Yes it is completely new. Just got it for Christmas. So far I surf the net, listent to music, I play Counter Strike Source and Left 4 Dead 2 via Steam, and now World of Warcraft as well. I also watch DVD's and Netflix on it, and I'm gonna start messing with garageband, mixing music, etc. I turned off bluetooth, I don't even think i need that, and my brightness is about 4 boxes from full

Exactly. Also, trying to jump your car off with your MBP's battery will decrease its life span.
