Hello everyone,
I have noticed that when I wake up in the middle of the night or when I wake up to get my from the charger, that there is a slight but noticeable high pitched electrical sound coming from my phone.
It seems to be the most noticeable when it's on the charger but not actively charging like when it's sitting at 80% (I have optimised battery charging turned on) or when it's sitting at 100%.
I have tried multiple original Apple USB-C cables and adapters but I still hear the high pitched electric sound.
It doesn't really bother me, but I was wondering if anyone else is experiencing the same sound and if it's harmful to my phone?
