Hard to drain the battery completely

That last 20% of the battery lasts all day, huh? :eek::confused::rolleyes:

Modern batteries actually prefer to have some charge left in them, likewise, they don't like to be constantly at full charge. A happy medium is best =)

I don't think that explains why your iPod doesn't seem to drain fully, without owning an iPod I can't tell, it might be designed to function like that though?

Leave a movie running overnight. That may do it.
