For anyone who is interested, here are the results of my test:
DSL (Full Charge @ 2nd Brightness) & G6L w/ Passcard3 -
~6h + 52m (RED LIGHT)
DSL (Full Charge @ 2nd Brightness) & G6L w/o Passcard3 (removed each time @ G6 menu) -
~8h + 4m (RED LIGHT)
Difference =
1h + 12m
The tests were not perfect, but I think they are fairly accurate. I simply glanced at the time every time I turned the DS on and off and made note of it. I also tried to play similar games for each test. For the test w/ the Passcard inserted, I
primarily played "New Super Mario Bros." & "Mario Kart." For the test w/o the Passcard inserted, I
primarily played "Mario vs. Donkey Kong 2" & "Super Mario 64 DS." Notice I said *primarily* for each test; I may have played a few other games for very short periods of time (i.e. "Tetris"). Obviously, it would be most accurate to use only one game for testing, but that's boring!
Based on my results, I would venture to say that the Passcard is definitely affecting battery life. Some argue that it doesn't because you can obviously remove it. However, it cannot be removed
during game play (only @ the menu), which leads me to believe it is being accessed.
