My 1 month old DS Lite's battery has been playing tricks on me... It says on the manual that the battery life of the unit is approx 5-8 hours (on maximum brightness), but when I use my DS on its full charge levels, I can only attain let's say, about 4 hours... I'm using an old EDGE (white version) Korean DS Lite, the games I played in 4 straight hours are plants vs. zombies and final fantasy tactics A2.... (yeah, i use the touch screen most of the time) can someone tell me if my battery is failing even thought its brand new?? P.S: I Didn't charge it when 1 bought it the first time, the manual that came with the package is written in korea, so I was poorly informed that it should be charged before using it for the first time.. I've searched the net, forums, everywhere and they say that failing to charge the DS Lite for the first time will not affect it's ability to hold a charge... any response is very well appreciated! Thanks!
