Has anyone else noticed a very quiet ticking/fizzing noise when charging there phone with Qi. I use a fatboy charger that is completely supported by Nokia (it came bundled with the phone and has Nokia all over the box) so I know its not a compatability issue but im concerned that it is damaging my battery every time I charge up my phone wirelessly. It was one of those things that took me a while to notice, but once I did I could never unhear the faint ticks of the phone charging. I just wanted to see if it was happening to others as well or if its just me and maybe I need to get a new charger. Any help is appreciated, thanks
