so I recently bought a macbook pro 15" quad core, and it said that it has about 7-8 hours of usage, however I'm only getting about 5hours of usage, what should I do to increase the battery usage?
And I also have to charge my macbook basically everyday, sometimes twice a day.
MacBook Pro, OS X Mountain Lion (10.8.2)
The projected battery charge life is not a guarantee, your individual use pattern will impact that projection. If you have all radio transmitters on, WiFi and Bluetooth, shutdown what you don't need. Reduce the frequency of the Mail push and any other searches you have going in the background. Reduce display brightness. Completel terminate all applications when you finish. And the rest of the usage from your applications you have to live with as part of computing.
If you can run on line power part of the time, do so.
Then start keeping track of beginning charge level, ending and time so you get an accurate picture of your usage.
@Ralph I don't have radio trasnmitters or bluetooth on, but my wifi is. Aside from that, I've only been using web browsing and it still drains the battery life.
You said, "And I also have to charge my macbook basically everyday, sometimes twice a day.". If the conditions permit, keep your MBP connected to a wall outlet. There is no need to just use the battery all the time. It will just accelerate the battery deterioration.

Ciao.
I thought keeping the macbook plugged in with the power source will cause the battery life to deteriorate more... or is that just a misconception?

Once battery is charged, and charger connected to the power, it will run from the power source
Just a misconception. Leaving the MBP plugged in will not deteriorate the battery, however it is good for the battery to take it off-line periodically/monthly and give the battery some exercise. Discharging deeply regularly is far worse for the battery than leaving it plugged in.
When apple came up with the 7-8 hours they also had the screen dimmed to 50%, so if you are running it even at 70% with that many pixels you might be able to notice a drop in battery life, and at 100% a really noticeable drop.
