Hello, I'm not sure this is the right section to post this thread, so please move if I'm wrong, my apologize in advance. Lately I'm beginning to notice my DSi start to flash its low battery light after like 5 hours of gaming, which is not anywhere near of advertised battery life by Nintendo. My guess is the flashcard must be draining more power compare to regular cartridge since it has a microcontroller inside handling various things... But having some basic knowledge about microcontrollers myself, generally they consume very little power and shouldn't make the DSi last 5 hours shorter than expected. My DSi is only like 3 months old and the battery shouldn't be degrade that much, IMHO. Mostly I'm playing at level 2 or level 3 of screen brightness and my games is in 3D (Zelda Phantom Hourglass, this should affect battery life, right?) How long does your DSi last with Acekard?
