    Try opening the following link with a web browser that supports WebGL (e.g. Chrome):

    WebGL Water

    The power wattage can be viewed in "Basic" view of Power Manager.

    My X220 (i7 and 9-cell battery) lasts about 2 hours at 45 watts.

    Mine predicts me 2h55 on 67%, which extrapolates to 4h35. Battery capacity is 102.24Wh.

    Don't have Power Manager installed, but the extrapolated wattage is 23.5 watts. Firefox 15 on integrated GPU at 1718x1050 (not sure what viewport size).

    EDIT: My CPU freq is capped at 50% on battery. Seems to provide me the optimum battery life and responsiveness.

    EDIT2: For future reference, it's a W520/i7-2720QM/Q2KM/FHD/6300/WD5000BEKT.
