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

We're somewhere between #5 and #6. The sooner we get to #15 the better. :D


Here's the typical cycle for problems reported on Apple products:
  1. A few members post reports of the problem, report it to Apple
  2. No response from Apple
  3. Increased number of people report the issue
  4. No response from Apple
  5. Apple apologists dismiss the reports as very rare, the result of trolling, or exaggeration by drama queens
  6. Even more reports of the problem
  7. No response from Apple
  8. News of the problem hits blogs
  9. Apple apologists dismiss the blogs as simply engaging in clickbait
  10. No response from Apple
  11. Those affected by the issue threaten a class-action lawsuit
  12. Apple apologists decry the "sue happy" nature of American consumers
  13. Apple acknowledges the legitimacy of the problem
  14. Apple apologists are silent
  15. Apple release an update to correct the problem
or
15a. They set up a "program" to address the problem.
16a. Apple gains some positive publicity
17a. Apple apologists applaud Apple for doing the "right thing". (for an issue that they said from day-1 was not actually an issue)
18a. First hand experience with the “program” reveals very strict guidelines and restrictions that greatly reduce the number of affected customers that can participate in the program.

This is called CPU whine, it usually occurs when processors have too little to do. it usually sounds like a faint beeping sound, the original core-duo intel chip had CPU whine. This of course is a little different as it is reportedly occurring when the processor is under load, instead of idle. It would be interesting to see the ambient radio environment the hissing is occurring in, the high load hissing may be a harmonic resonance issue with other local signals. I would ask all the hissers if their wifi that is 2.4ghz or 5ghz, it would be interesting to see if there was some correlation.

Wonder how that happens when these processors are so tiny (no fans inside obviously).
 
I definitely have a model affected by this. I thought it was feedback from the microphone in the back but nope. Oh well once apple has stock they will replace them no problem.
 
Breaking news! CPU's make noise, especially when held close to the ear.

The crazy part is when I use my phone at a normal distance and not pressed against my ear I don't hear anything.

Neither the 6/6plus nor 6S/6S plus make this coil whine noise so saying it is typical of electronics is nonsense. Especially if not all devices have this issue.

I have tested an iPhone 7, two iPhone 6S and an old iPhone 5S.

They all have the "noise". But you can only hear it a quiet room while pressing the back of the phone against your ear - how often do you do that!??

Damn. Mine has this hissing problem too. 7 Plus 128GB. I noticed yesterday when I was on a phonecall that there was a loud annoying hiss but I thought it was the connection. I just powered down, powered on the phone and it's definitely hissing in the back.
 
I can hear that same sound with my 6S if I press my ear against the back of the phone. I don't know how loud the 7 sounds though.
 
my iphone 7 is doing it even in idle! It has nothing to do with load!

I had the similar issue after overclockig my old core i5 from 2,8 to 4 ghz. after that something (MB or CPU) did a similar sound, especially during activity of the HDD (was an SD)

Yes. With my ear right up against the back of the phone.

Not an issue.

Yep, mine does it too. I first ran the benchmark test over the weekend when Engadget posted about it, and I heard nothing at all. Then I took the case off and pressed my ear against the back, and sure enough, a very definitive RAM/CPU whine. Not just when under load, but there's a squealing noise all the time. In fact, I'd say it's less noticeable under load since it's constant, whereas at idle it's on and off. Now that I know what to listen for, I can hear it a few inches away with the case on.
 
How does anyone think this is an issue? If you put the BACKSIDE of the phone up to your ear you can hear something very softly. So what? Can you please find something to complain about that actually matters? Maybe complain to apple how cupping your ears makes you hear the ocean. #oceangate


What a bunch of drama queens.

Apple just need to release a statement saying this is completely normal behaviour.

That'll shut everyone up.

Wont work considering that not all devices are affected. I predict they'll do a soft recall - they'll replace units for customers that complain, with the expectation that the majority of users wont know about the issue even if their phone is affected. At the same time Apple will identify the source of the issue and modify the production process so that newer production isn't affected.

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???

OMG. Do you think it might be a horcrux?
 
iPhone 7 Plus, 128gb Black, in Canada...no hissing on mine...but, interestingly, I checked out the Ice Storm Extreme benchmarking app mentioned that Engadget used.

Ice Storm Extreme, run on the 7 Plus, doesn't give a score...too light a test, it described. According to what I found, the same company has a newer test, Sling Shot (with various levels...Sling Shot, Sling Shot Extreme, etc...)

In the app, it highlights Sling Shot Extreme as the recommended level...however this crashes on opening on the 7 Plus, as well as 6s and an iPad Air 2. Sling Shot will run on all 3, with the iPad Air 2 giving the highest score (2394), and the 7 Plus (2280) only 7 points ahead of the 6s (2273)...frankly, I'm disappointed where the 7 Plus landed here, given it's got the "fastest chip" Apple has ever produced.

Thank you for fulfilling #5 on the roadmap. The sooner we get to #15 the sooner those affected will receive a solution.
