It'll be interesting to find out how widespread this issue is and if Apple will ever come out and confirm what the actual cause it and what, if anything, they'll do about it.
Crap mine is doing it to. . Wait I think it's just my snake. . .wait I don't have a snake. . .or do I?
After the iPhone 7 and iPhone 7 Plus began arriving to the first round of pre-order customers on Friday, a few users noticed what's become known as a "hissing" sound emanating from the back of the device, where the Apple logo is located. The first reports began on Friday, but the occurrence gained ground when 512 Pixels' Stephen Hackett tweeted about it, posting a video with the "terrible noises" produced by his iPhone clearly audible, which he determined to be caused by heavy performance at the time.
When he brought the issue to AppleCare, Hackett was told to bring the iPhone into an Apple retail location to swap it out, but given the low stock of nearly all iPhone 7 models, that solution isn't particularly helpful at the moment. Friday night, a member of the MacRumors forums, liorgr, confirmed the somewhat "common" issue facing the iPhone 7, although it's still unknown as to whether the noise could come from all versions of the device, or if it's just "a faulty batch."
Since his tweet, more and more iPhone 7 users have come forward about the issue and corroborated Hackett's story. On the MacRumors forums, mentions of a "buzzing" and "static" sound coming from the back of the iPhone 7 and iPhone 7 Plus began on Friday afternoon. Specifically, forum member maxlind noted that the noise happened on his 128GB iPhone 7 Plus under load, without charging or restoring from an iCloud backup.
One Redditor who got his iPhone 7 Plus replaced at an Apple store noticed immediately that his new iPhone was making a similar sound, so the issue could potentially be affecting a large number of iPhone 7 and iPhone 7 Plus models due to the high-capacity performance abilities of the A10 chip. Since there are no actual moving components on the chip, it's still unclear what could be making the noise.
As pointed out by The Verge, the consensus of the noise's origin online is that it's caused by a phenomenon known as "coil noise."
Still, despite the problem slowly becoming infamous over the weekend, some sites tried to replicate the issue and failed. Using performance benchmark software 3D Mark "Ice Storm Extreme," Engadget ended up hearing "no hissing at all" on the 4.7-inch iPhone 7. As many users have theorized, the sound issue could "stem from a manufacturing issue instead of an inherent design quirk." Until Apple addresses the problem, that still leaves affected users to either deal with the noise, or attempt to get a replacement that could potentially face the same sound.

How about a 'class action'?
I'm a firmware engineer. I bug my electrical design counterpart about this all the time. Mostly to tease him about it. Sometimes I try to program parts to play different tones just to poke him more.Likely a quasi-stability in one of the SMPS modules, causing a resonance in one of the ceramic capacitors.
Am a electronic design engineer.
No one wants to be recording audio or video with hissing sounds. Cassettes and VHS are long gone. This needs to be resolved.
This is certainly interesting. Anyone here with technical experience with CPUs able to describe more in detail what would be making the processor sound like this?
I have a Verizon 7+ that is doing it. Only noticed after reading this thread and listening extremely closely. Not going to bother me at this point.
Or people could just stop trying to find problems with things and create iGates out of them. Do people seriously have nothing better to do with their time?
I get a definite high pitched tone in my recorded videos if something is going on in the background on the phone. For example, if I reload a web page and then switch to camera and record a video while the web page is loading. Sound stops when the page finishes loading and then you just get the normal background noise. I tested this with an iPhone 6s+ and my 7+ side by side. You can hear the whine on the 7+. Then I swapped the video files between the phones and played them back again to account for different speaker design. Definitely hear the whine.If it's the CPU and not the GPU/HW encoding section then there would be no hiss while shooting a video.
I have a theory, the iPhone 7 is the true Slytherin heir...
first "iPhone 7" is a very unusual name for a phone, what does the number 7 remind you of? Horcruxes of course! Voldemort split his soul to seven pieces!
Second, apparently people (or muggles) are hearing "hiss" sounds, guys this is the iPhone speaking in parseltongue, calling its master...
Third, the iPhone 7 and 7 Plus come in two new colors, what are the colors? Black and jet black! And voldemort always wears a black robe...
And lastly, The only new stock wallpaper in iOS 10 is a green waterfall, green is for slytherin.
Apple is slytherin, and the iPhone 7 is the slytherin heir.
Edit: OH AND ALSO, The apple, in the old testament was a tool the devil (THE SNAKE) used to lure eve into the sin! Apple! snake! Are you getting it???
The device. Right about the position of the Apple logo for me. The camera mic can pick it up pretty clearly.Is it coming from the device itself, or the speakers?
I load a web page. That's all it takes for me.what app are you guys using to put it on heavy load to test this? Geek bench?
If I had a time machine I'd go back and rename that building Wateroopsiewoopsie, and then get back the current day and enjoy going through the news archives... "antennaoopsiewoopsie", "bendoopsiewoopsie" etc...Please no more "gates"....
