I have an iPad mini 2, and when I plug it in, it immediately shows the Apple Logo, and then turns off after a couple seconds. I would assume I need a new battery because it turns off right after it’s unplugged, but is there any way to know for sure? Thanks!

Sounds like a bad battery, Just replace your battery and check. If that doesn’t fix it bring it in to a reputed micro-soldering company for them to take a look at it. Cheers!
