it says it was fully charged but once i pull the adapter it only says i have 2hrs of juice left.

Don't have much in the way of things going. a couple safari windows, and word. brightness is 3 down from fully bright

I did just calibrate the battery based off of apples instructions.

If you look at your consumption, 2047mA you will see that about 2 hours is correct for the current battery capacity.
What may not be correct is that your MacBook consume so much for your tasks.

Check with activity monitor your CPU usage. How much does it report? Are you using anything that is powered by USB?
 
Yeah, I have a 17" MBP and I only see 1800ma battery drain; yours is definitely high for a 13" screen. As misterredman suggested, you must have the processor(s) ramped up and/or something else draining a lot of power.
