Is Your iPhone 7 Hissing?

Some users are reporting hearing strange noises coming from the headset
September 19, 2016

A few iPhone 7 customers have reported hearing a strange hissing sound emitting from their new handset. The sound is coming from the back side of the device, according to multiple reports.

The first reported hissing sound occurrence came from Stephen Hackett from 512 Pixels, who posted a video featuring the “terrible noises,” as you can hear below:


According to Hackett, Apple has decided to replace his handset:

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.

So what’s causing this hissing sound? The Verge notes:

The consensus around the web right now is that this is some form of “coil noise” or “coil whine” — the sort of sound a high powered processor or virtually any electronic part can make, especially when it’s not properly dampened. It can crop up when the chip is under heavy load, and you might be able to hear it on any recent phone if you put it under load and listen very closely.

What you can do

If you’re experiencing problems with your iPhone 7, contact AppleCare immediately. Every iPhone comes with one year of hardware repair coverage through its limited warranty and up to 90 days of complimentary support.
