My iPhone 7 Plus Is Hissing! The Real Reason Why

Here we can see, “My iPhone 7 Plus Is Hissing! The Real Reason Why”

On your brand new iPhone 7 Plus, you’re watching a movie, playing a game, or using your favourite app when you hear a very faint hissing noise coming from the back of the smartphone. Even though the noise is hardly heard, you can’t help but wonder if your iPhone is malfunctioning. “Aw dude,” you lament, “my brand-new iPhone is already shattered.”

Fortunately, your iPhone is most likely in working order. In truth, a large number of iPhone 7 Plus owners around the world have reported this “problem.” In this article, I’ll explain why your iPhone hisses when it gets hot and how to fix the iPhone hissing speaker problem.

New iPhone Owners Say “Boo! Hiss!”

Many iPhone 7 Plus owners have reported hearing a faint hissing sound emanating from the back of their device. When the phone is performing other tasks that need the iPhone’s CPU (aka: the iPhone’s “brain”) to do a lot of work — in other words, when it becomes hot — this has been reported to happen.

When I record video or launch apps, I hear the noise. This noise has also been reported when charging the newly introduced iPhone.

Is Hisstory Repeating Itself?

After further examination, some customers have discovered that this issue isn’t exclusive to the iPhone 7 Plus. Several reports claim that the hissing noise is also present on previous iPhones but went undiscovered since the noise is so low on these devices. It’s also worth noting that, because everyone’s ears are different, some people may hear their iPhones hiss louder than others.

Is My Brand New iPhone Broken?

Because this is such a common problem, I believe it’s safe to assume your new iPhone is in perfect working order. When utilized to process data or do other activities, electronic components in computers, phones, and every other electronic device create a little noise.

Why Is My iPhone Hissing?

Thermal noise, often known as coil whine, is a hissing or high-pitched sound produced by electrical circuits when they heat up or consume more power. When performing hard operations, the processor within your iPhone grows hot and needs more power, which warms up the speaker amplifier and causes a hissing or high-pitched whine.

Is There Anything I Can Do About My Hissing iPhone?

The iPhone 7 Plus hissing issue has yet to be addressed by Apple because the issue was initially noticed the weekend after the phone was introduced. However, I expect Apple to publish a statement next week explaining why the iPhone 7 Plus is hissing and possibly offering a software repair in the future.

User Questions

1. What is the source of the hissing sound on my iPhone?

According to Hackett, the hissing sound is similar to what you could hear from a speaker that isn’t properly connected, and it gets louder when the iPhone 7 Plus is “under strain.” Some customers have described the sound as resembling the buzzing of a laptop fan, even though the iPhone 7 Plus lacks fans.

2. What can I do to make my iPhone stop making noises?

Drag the Ringer and Alerts slider back and forth in Settings > Sounds (or Settings > Sounds & Haptics). If you don’t hear anything or the speaker button on the Ringer and Alerts slider is darkened, your speaker may need to be repaired.

3. On the iPhone 7, what is phone noise cancellation?

Phone noise cancellation, which was initially introduced in iOS 7, detects ambient background noise and generates an inverted audio signal to cancel it out, so you don’t hear it during a phone conversation. The system works best when there is constant low-level background noise, and it usually does.
