i bought a refurbrished unit from the nintendo store couple months back and it recently was acting weird a month ago. i still have warrantly but i really dont want to spend the time sending it in if it's a battery issue.
1. i'm not sure how to reproduce it but it shuts off and then when i turn it back on, the battery indicator goes blinking red. charging it is fine but it's strangely quick.
2. again i dunno how to reproduce it but if i turn it on and shut it down then close the 3ds lid, the battery and power indicator lights up. it's like it's on but the screen isn't on.
3. it only happened a couple of times but i think it went away but when i was playing senran kagura or donkey kong (both are download games, i tried it with physical and it doesn't seem like it will do it), sometimes if i press start to skip something, it turns off or it goes to some weird screen with white and black horizontal lines.
