Also if you are in the lock screen press the home button twice in quick succession, it will brig up a music player.
Thats what could be happening, it could be getting pressed accidently in pocket. I'm not aware its playing as its on silent, I only see it when I check the time or for texts. Maybe its not actually playing as I see the music player at the top and assume it is and the battery life thing could be as Bob Fleming suggested.
