Then this electromagnetic wave is converted into sound energy due to which users are able to listen audio, music, movies etc on their mobile phones.

The electrochemical energy that stored in a cell is removed as electrical energy in the process of discharging. There are so many other thermal and electrochemical processes taking place at the same time.
