How long does a Mp3 player last without charging?

[q and a]

I am trying to find out how long my Mp3 player will last before I have to charge it. How many hours? What about a Walkman, how long do these last? I would love it if someone could see how long it will be before it goes from full battery to needing charged.

Thank you in advance.
