I got my iPod replaced but now I have another problem?!

My previous iPod 5th generation home button got stuck and I got it replaced. Thank you.

But now this other ipod that's obviously been used before isn't good either. I was able to do a lot before with my iPod touch before he battery drained. With this one, after only an hour and I just watched 2 videos, and browsed the web a bit, it's at 60%!

That makes zero sense. At least 5 other people had this one before me because it kept asking me to input password for all these other emails...

So did Apple just give me an iPod touch that was already used?! Aren't they suppose to give you a brand new one?!

Is there anyway I can fix this battery issue or do I have to get it replaced AGAIN?

I prefer my other ipod even if the home button was stuck. At least the battery actually lasted...
