Tried playing a game on it a while ago, and when the charger is plugged in it works perfectly fine. When it isn't, it discharges very quickly (not immediately, but definitely in less than a minute). I haven't opened it up yet, because I don't really know what to look for and how to know for sure if the battery is the problem.
What could the issue be + what do I look for to see if that's the case with my DSi in particular?
