I hear buzzing sound coming from the back of my iPhone 6s, what seems to be the problem?
y new iPhone 6s 128GB has an odd buzzing / static sound coming from it. ... hear the battery or processor or something “working”
omarfromcyberjaya,
Try a restart: Restart your iPhone, iPad, or iPod touch
How loud is the sound? Can you hear it at a normal distance from your ear?
If yes, make a Genius Bar appointment to have it checked.

Good luck.
