I use a DS Lite and I more or less leave the charger permanently in the DS. Anyways, lately, my DS has been dying on me. Even though the charger would be in, the battery would go to red and I would realize it wasn't charging. I'd shake the charger around for a bit, take it out and then plug it back in and change angles and etc. and sometimes it would charge again. Usually, it doesn't charge when the DS is closed but charges during games, but I don't think the battery is always full when the DS is closed. There was a period when it just plain out didn't charge. I tried to clean it up a bit since I thought there was debris in there cutting off the connection, and that kind of worked. It now charges at random like before. Anyways, my question is this: is there a problem with my DS, Charger, Battery, or is the connection just bad? If the connection is bad, is there a way I can clean it efficiently or fix it somehow? I want to know which one of these I would need to replace if something's broken.
