Noise when charging wirelessly

[neil74]

Have had my S8+ since day one and today I have noticed an issue when changing wirelessly.

When charging on a QI pad there is a noticeable hissing/fizzing type noise from the phone, it happens on all of my qi pads but does not when plugged in wired.

Obviously given the N7 issues slightly worrying. Anybody else experiencing this?

Coils buzzing. Nothing to concern yourself with unless the buzzing is loud and noticable at distance. I find the Samsung fast wireless charger to be quiet. My old Tylt wireless charger causes slight buzzing.

I guessed it as it only happens on wireless charging that it was the coils; however, whilst it is not super loud it does not strike me as right and it did not do it until yesterday so something has changed internally to start the noise.
