I know the dsi does not have the greatest battery life and so I want to buy a flash cart that does not drain to much of the dsi's battery. I did see the forum about the battery tests but I want to know from you guys what your dsi's battery life is using the Supercard DStwo. I am not interested in knowing the battery life stats based on the highest or lowest setting. I want to know the stats in terms of using the dsi at an average brightness (lets say at brightness setting 3 or 4 because doesn't the dsi have 5 brightness settings?) and volume using the Supercard DSTwo because those are the settings that I will be playing at when I get a dsi. Also, did you guys find that the Supercard DStwo made the dsi's battery life worse, better or the same. Again, not necessarily interested in battery life tests, just want to hear in general what you guys think.
