    recently I have noticed my Lumia 920s wired charger has been making a really high pitched sound.
    (not sure if its only me that can hear it as I can hear those sirens they have outside shops/cafes to keep animals away...yes I'm super human)
    just wondered if this would be something to worry about or if others have had the same thing.
    it got really bad last night to the point where I couldn't sleep (as its so high pitched) and I ended up unplugging it altogether.
    the noise follows the charger too doesn't matter where its plugged in.
    any solution to me getting my 4hours a night sleep back is totally appreciated
    thank you
