Someone tried to skimp on solder or insulation between the big A10 chip and the case as heat causes movement?
Got a tip for us?

iPhone 7 and 7 Plus Exhibiting 'Hissing' Noises Under Load for Some Users

Seems an unrealistic number given how many users have now officially stated they have contacted apple on MR alone.
Coil whine is normal in any coil operating at high frequency.
That's still perfectly safe, however it's not acceptable in a consumer product, they should be boxed and glued to not be heard by the user, many brands don't respect the consumer on this, but Apple shouldn't be one.
For example I have an Asus WiFi AP that makes coil noise and a Samsung phone charger that cost me some nights of sleep until I traced it out (in my ignorance I thought that Samsung was a good brand and they wouldn't let that happen), those devices are farther away than my hears than my phone and are more audible, but neither Auss or Samsung take responsibility.
Apple obviously missed the "sssSSSS" at the end of the iPhone 7 name.
These companies just need to relax, chill out, and launch when their products are ready. Save a lot of hassle down the line for everyone involved, customers, company, shareholders, media...
I totally have a #hissgate phone.
iPhone 7+, 128, black. But I have to put my ear to the back to hear it. Even half an inch away and I can't, much less with the case on. Makes it more funny than anything else.
If it were louder it wouldn't be funny at all.
Edit: CRAP! When I record a video, the hissing is pretty loud in the video. I didn't think about that.
Not funny any more.

Look in the mirror. You're on a Apple fan site replying to a stranger lol
I did 10 app updates last night and held my phone up to my ear. If I put my ear just in the right spot, while it's warm (doing the app updates), I can hear faint noises within. I wonder if that's the same issue. Heck, I wonder if my other phones did it and I just didn't hear it.
Actually, processor packages can make a whine too. It's not just coils that can cause coil noise. The noise comes from the rapid contraction and expansion of parts from the force of the oscillating current moving through conductors. Coils tend to be the loudest and most obvious, but even chip packages and other components can start vibrating.
It will likely make the same sound, as did previous iPhones and other electronic devices when large current demands are made, due to large processor loads/demands. Not unusual in such situations. And if you listen very carefully. It's very faint.
Well, yes..... yes we do.
(I totally get your point here. It's got to be quite a challenge for manufacturers / designers to build a device with this many parts packed so tightly, INCLUDING both a cellular and a wi-fi radio inside, and *not* have some kind of RF noise or hum present.)
But consumers expect a new version of an existing product to have the same basic characteristics as the one that came before it. So yeah, they're going to demand an iPhone 7 or 7 Plus is just as "quiet" as the 6s, 6, 5, or 4 series.
I don't really fault Apple for this happening on at least some of the new phones. But they definitely should address it as a valid warranty claim and exchange it ASAP for those affected. (Looks like they're doing just that.)

Likely a quasi-stability in one of the SMPS modules, causing a resonance in one of the ceramic capacitors.
Am a electronic design engineer.
My 7P doesn't make the noise. Ran a bunch of benchmarks yesterday after I got it to warm it up and still nothing.
On another note, even after running numerous sequential benchmarks the scores remained high. So not only did I not notice hiss, but this phone isn't throttling. Unlike the S7, which starts to slow down after a few minutes.

Coil whine... the bane of my existence since Intel released the Core i processors. All 6 laptops I've had with i5s and i7s have done it. Some days at work it is bad enough to give me a headache. Either have to pile on the ibuprofen or listen to music. Can't wait until my phones start doing it!
Thank you. Very interesting. Are we possibly pushing the limits of these devices or would this be a fault in the actual design of the software, or the hardware?
