MacBook Pro Retina battery?

Question

Hey guys, I just got a MacBook Pro 13" with Retina Display and the battery life seems quite mediocre compared to what it's promised to have.
I get about 3:00 when editing lightly using Aperture which I know isn't the most simple application. I'm just worried cause Apple promises 7 hours, I know that is web surfing but (correct me if I'm wrong) I don't think that Aperture would be using double the power. My brightness is at 50%, backlit keyboard off aswell as bluetooth.
This is also my battery stats.

I keep my MBP plugged into mains about 90% of the time - and on battery about 10%. I seldom let it run down below a 30% charge and my battery is still at 98% battery health after 8 months.
Just be certain that you do run on battery occasionally, if you're plugged into mains the majority of the time. At least twice a month, let your battery drain down to 10-40% and then plug your computer back in. This will keep the ions moving and give you a healthy battery for years to come.
