Some people say that charging whenever is bad, and I usually end up waiting until whatever I'm using (in this case, my 3DS) is dead before I charge it. However, I'm about to go out for a while and my 3DS is only half charged, and just in case, I'd rather have it fully charged. That being said, will charging it now lessen the battery life in the future? Or is it totally safe if I just plug it in now and let it charge. Thanks in advance.
