Okay, so my iPod (when it's fully charged even) lasts only a few minutes on it's own battery. I've had it for years, but rarely ever use it. I've got a 5th Gen (one of these) and I don't know if it's the battery or what.
What are we supposed to say? That's weird, maybe it doesn't last long because it's on max brightness and audio and you're watching videos or something. Are you being conservative of it's power?
Yeah, I really don't do a whole lot on it...it lasts no more than 10 minutes on average. And the battery is internal, so I'm not entirely sure how I would replace it myself.
