Oh My God, i over charged my DS last night.. i charged it from 12mn till 3 in the afternoon.. I just hope that the battery will not spoil so fast just because i overcharged it for one night.. =( Right now i am charging my itouch but i am sure i will not overcharge this because i am charging it using my lappy and the latest time that i will swtich off my lappy will be at 2. so there wont be a possibility for me to overcharged it.. =)
