    Amperage (mA): -2047

    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.
