Put your iPhone on silent, play a song or any sound, stop it then immediately put your iPhone speakers near your ear, you will hear a sort of noise which stops after a few seconds, even if you play a game with music/sound off, it send out that noise. It's definitely a bug since it's doesn't happen under iOS 6. It's a phantom battery killer! Does it happen to you?

Just tried it on my iPhone and you're right. It's like a static noise isn't it? Kinda weird but I doubt it affects your battery at all.

Yep exactly! I think it does affect the battery since if you are playing a game with music/sound off, it still has that static noise. It means the speakers are active when it shouldn't be.
 
Sound doesn't really add on much to battery usage even if you have it up.
 
great find! ... i just tested it out and my static sound stayed on for approx 20 seconds.
