High pitched buzzing from charger - Samsung Galaxy S7

[Capricorn90]

Hi,

I'm hearing a high pitched buzzing sound from the Samsung Galaxy S7 charger, it seems to be after it has been on charge a while and often wakes me up around 4am - the noise definitely stops when I switch the charger off at the wall, my partner doesn't seem to hear the sound though. The phone and charger are about 2 months old. Has anyone else had this problem? I don't know if it's something to worry about or not, or if it's just bad luck and another charger may be quieter?

Thanks.

Is it the wired or wireless charger?

It's the wired charger - sorry I should have said!

I don't hear a high pitched sound with my wired charger, though I use it at work and it's not as quiet.

I'd a 3rd Party charger that did this with an older phone. I generally don't trust noises, especially when it's something that's supposed to be charging my phone so I binned it.

I wouldn't expect the standard charger to do this though.
