Topic: My 3DS is playing tricks on me

This morning when I turned on my 3DS, it told me the battery was nearly dead and needed charging, even though it was fully charged the night before I went to bed. I connected the charger, waited a bit, and turned it on a bit later. The battery light that would by this point have turned green, was still red, and when I removed the charger it was still blinking and was still at the lowest point of battery life. I left it charging for a couple hours, but the same problem occured when I removed the charger again. I could turn it on and play it just fine, but it just didn't seem to be charging up anymore. So I decided to try a different charger, to see if that would fix the issue. After about five minutes of charging, the light went out, and when I turned it on, it was apparently fully charged.

I'm left a little confused here, because the problem clearly isn't the charger I replaced or the battery, but more an issue with the system itself. Has anyone had this issue or a similar one before? It has me a bit worried. (The system is a New 3DS XL Fire Emblem SE, and has only been used for about a month)

Thanks.

I dunno, I had a weird charger moment too...where it wouldn't charge my 3DS at all. Tried another one and it worked, so I assumed the other was dead, tried it again just to be sure and it was charging again. >.>
