Hey all! Yes, Don't flame me! I figure this topic has been done (in one form or another) before, but I would really like to get a clear answer once and for all, and get some closure on the subject. All things being equal (DS Lite age, screen brightness, volume setting, memory card size & speed, type of flash card etc.) does the DS Lite battery last less while the EZ 3in1 is just sitting inside slot-2, even though the DS is JUST running DS games? If so, in minutes/hours, how much less? Opinions, personal experience, thread links, anything on the subject would be appreciated. Thank you!!!
