Apple's iPhone 7 Hissing Sound Finally Solved

Is your iPhone hissing? Some are reporting that their iPhone 7 is doing just that when it's pushed to the furthest reaches of its processing power. As indicated by 512 Pixels, this hissing sound has been occurring on different iPhone 7s and 7 pluses all across the country. If you can hear it, it's not something that you should not neglect. That unquestionably is a hissing sound on your iPhone 7. It's very alarming considering that most phones that start hissing often end up exploding. So what is going on here? Is it a natural thing or is it some sort of a fluke?

Stephen Hackett at 512 Pixels was the first to notice and point out to the strange sound emanating from his iPhone and others immediately confirmed they are experiencing the same issue, including TechCrunch's Darrell Etherington.

The hissing sound explained

For the moment, there are a few speculations regarding why this is going on but no real answers. Engadget's Jon Fingas says that "some suspect coil whine or similar electromagnetic effects." He additionally points out that it's not a universal issue because he has "tested an iPhone 7 using 3DMark 'Ice Storm Extreme,' a performance benchmark that puts the processor under serious strain, and heard no hissing at all."

What you need to do

Author and iOS engineer Marco Arment has a more poetic take. "It's the phone equivalent of hearing the fans spin up loudly whenever your Mac's CPU gets used to its actual potential," he says. Apple Insider guesses that it "could involve the RF transmitter or some other form of interference with the speaker system." Either way, the best option that you can do to solve this matter is to just simply return this device to its retailer and request a refund or a replacement.

Still no response from Apple

We've reached Apple for confirmation and asked whether they know the cause of this error yet have not yet got an answer. For Hackett's case, Apple is replacing the phone so that might be an option if you are also affected by this hissing phenomenon. Sadly, that will likewise mean you need to wait for 5-7 days for a replacement.
