May be a silly qusetion, batteries and MP4

To try to get some sleep because of a strange hum at night, I have bought an MP4 player to play white noise, it seems to work, but of cause the battery goes flat , this noise goes all night, in fact its going now. The question is is ok to have the battery on charge while in use.TIA
