my ds is only getting about 4-5 hours of gameplay per battery charge. im playing phantom hourglass right now so this is definately not sufficient! how long are you guys getting per battery charge and is there any advice as to how to extend the life of the ds battery?
About 2-3 hours on wifi playing Mario Kart (when I can withstand playing that long against cheaters) Anything from 4-8 hours with any offline game depending on volume and brightness and what game i'm playing. I also have a spare battery and an external charger so when one battery is empty I can just switch batteries. If you have a DS Lite you can increase battery life by reducing the screen brightness, just going down one level will not make a huge difference to the screen, but will improve battery life. (I usually have my brightness set to 2 or 3)
about 2 hours with just offline gameing!!!! which really sucks! I thought that when you buy a ds, before you turn it on at ALL you should charge it to the max so the battery doesnt get well... damaged i guess, but i dont know if its true, i didnt do it but mabey it does have an effect. Correct me if im wrong tho
Yes you should fully charge it before it's first use or it can effect battery life (not hugely though) I didn't with mine as I traded in my old DS for the Lite and i wanted to transfer my Wifi settings over from the original DS so I could keep my Wifi scores and friendcode (and I had to do that at the shop before charging the DS at home).
