My iPhone 7 Plus is Emitting Noise From Logic Board (Updated) 

As my iPhone 7 Plus was restoring from iCloud, I thought I noticed some sound. After picking the device up from my desk, it was clear the sounds are coming from back of the phone, possibly from the CPU. It seems to get worse if the iPhone is under load. It’s loud enough to be heard even if the iPhone is just sitting on the table. I don’t have to put it up to my ear to hear it. 

I’ve heard from several other people with similar experiences, and others who are saying past iOS devices have displayed this issue. I’ve handled more devices than most, and haven’t come across this.

I’m not saying this is some widespread problem; I just wanted to share my experience with others who may be having it too.

After a phone call with AppleCare, they have decided to replace the phone. They were quick to try to solve the problem, and while I’m stuck waiting for a new phone for who knows how long, I appreciate that they worked to make it right.
