iPhone 7 Plus Makes Hissing Sound Under Load, Some Users Complain (businessinsider.com)
Several commendable users are complaining that their iPhone 7 Plus handsets are making a "hissing" noise especially when they do some heavy weight work. Some users note that this issue extends to the iPhone 7 as well. BusinessInsider reports:Stephen Hackett, cofounder of podcast network Relay FM, tweeted that his iPhone 7 Plus "makes terrible noises when under load," and shared an audio clip of the noise. TechCrunch writer (and former Apple employee) Darrell Etherington responded that his "brand new, just-unboxed [device is] doing the same thing right now." It sounds like the problem isn't affecting all devices, and it's not immediately clear what's behind it. Hackett said on Twitter that Apple will be replacing his device with a new one, which suggests it's a defect rather than just an unexpected quirk of the new smartphone's design. There's some speculation out there as to what's causing it - but nothing concrete yet. Engadget's Jon Fingas suggests it could be "coil whine," a process where electronics make an unintended noise while working, for example.
"You're listening to it wrong."
Only LUDDITE phones don't have appy app apps that sound like apps apping other apps! Modern app appers like appy Apple ONLY app apps, NOT LUDDITE software like LUDDITE Windows!
Apps!
I always wait a couple of months before purchasing a new device, especially in the smartphones department.
Slashdot, fix the reply notifications... You won't get away with it...
I would guess they chose an inductor too small and it is vibrating.
This is finally a proof that Apple made a pack with the devil itself!!
#hissgate
I have noticed this in most equiptment over the past 30+ years of computing. I remember hearing the processing noise from my old Amstrad PC-1512C 8086. Which didn't have any cooling fans so when I did heavy processing it would make a whining sound.
I also hear a whining sound from my wireless router, I can often hear noise on LCD Displays, especially on a full screen refresh. I expect the the iPhone 7 it is doing so much stuff (whether it being useful or not is open for a another internet flame post) and the new CPU allows it to do more enough to cause a noise.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
Take two antiHISStamine and call Apple in the morning.
Agent K: A *person* is smart. People are dumb, stupid, panicky animals, and you know it.
...They're haunting Apple. "Bring us baaaaaack.....*hiss*......Bring us baaaaaaack....."
It's the sound of your soul being sucked into the device. That's why it's noticeable on a "brand new, just-unboxed device". Should go away after a few days, once you are completely soul-less.
I eat only the real part of complex carbohydrates.
That's not a defect, that's a feature. The A10 fusion chip in the iPhone 7 plus is so powerful it emits a tiny but audibly perceptible exhaust note. Kinda like performance tuned autos.
Obviously just the hard disk spinning up and down. Apple should have considered these effects and used a small page file with more ram. Nothing to see here.
Back to VisiCalc.
Someone at Apple has been coding in Python instead of Swift.
Apple iPhone, proud sponsor of house Slitherin.
"That's the way to do it" - Punch
That's gotta be a part of their "courage"!
Given that Apple is apparently quite obscessed with making their device the same thickness as a sheet of onion skin paper, the issue is likely a combination of things.
Namely, thermal noise needs to be overcome with higher voltages, which then get switched at pretty high speeds. That switching of higher than normal voltages (because it is under load, and having to overcome passive cooling only) coupled with a most likely saturating floating ground, means RF signal leakage. Given that one of the proposed reasons for Apple's removal of the headphone jack was that they were having problems with RF noise being produced and picked up on the headphones (and nothing to do with "Courage") I find this likely, and suspect the issue to be more systemic than apple wants to admit, especially in light of the Samsung battery disaster.
(EG, the reality that you can't reasonably push a design that thin without having very real problems with the electronics does not fly well with the ivory tower designers with sticks up their asses at Apple, but their marketing droids pay better attention, and realize this is a potential problem they need to be mum about. I would expect higher rates of failure from out of expected tolerance voltages on devices driven hard, and apple blaming the users, rather than the hardware like they should be.)
"a process where electronics make an unintended noise while working" Thank you, educational side of Slashdot.
What is likely happening is that a DC-DC converter is getting yanked into >50% duty cycle and causing subharmonic oscillation. It's piss poor design on Apple's part, as usual.
Fix it fix it fix it fix it!
systemd is Roko's Basilisk.
It's channeling Steve Jobs from the great beyond!
kids these days. Coil whine actually involves coils, for starters.
Chinese child slave labor made it hiss
- Leaking; check tire pressure
- You've angered it
- UI is written in python
- You've received an xkcd phone by mistake.
- You have it set to SSB
- NSA is hiding messages in the hiss for mind control purposes.
We get that crappy design is causing the hiss. Thank you. Now please focus your efforts on more "hiss" puns.
So I guess the headphone jack had to go anyway if the electronic noise inside the case is bad enough to be audible.
I take it this is a first-world definition of "terrible"?
I had to turn up my speakers to even hear the video.
It's that sucking sound of money being siphoned away from suckers!
Must be that new Hi-Fi speaker in place of the headphone jack. It's not a noise, it's the soothing sounds of Steve Jobs talking from the dead to have "courage" with the new audio connection.
You live and learn. Here I was, thinking it involved grapes. You know, for the whine.
mother-effing snakes in this mother-effing iPhone!
I think that it just means the people who hear it are Parselmouthed and can hear the inner basilisk spell that runs the A10.
Some drink at the fountain of knowledge. Others just gargle.
I thought it was a way to run coils on linux instead of windows without using a vm or a coil container
I think you're on to something. Android is the GNU/Linux kernel, isn't it?
Not saying that what you experience isnt real, but having a brand new video card a few years ago with coil whine, i learned a lot about it. It is VERY noticiable. To everyone. I used to game at night and my wife said the noise was keeping her awake. With headphones on, it wasnt bothering me and the card itself was fine. It was a high pitched whine which everyone could hear easily. It started about a month after i purchased this video card. I had to RMA it, but the successive cards i recieved back all had different problems. After about the 4th RMA, it got to the point that I was paying more in shipping than it would cost to just get a new damn video card. So thats what I did. Never buy PNY anything is the moral of the story!
Coil whine, and being sensitive to electronics noises are two very different things. The latter being very detectable by everyone. I listened to the noise in the "article" and it sounds more like a feedback from a hot mic coming out the speaker or something like that, than what i experienced as coil whine. But who knows, smaller coils, different sound maybe.

And like cats, if you don't back off, it'll scratch you up, bad.
Apple have been pushing to get multiple suppliers for each part of the iPhone, I assume to get more certainty in supply and competitive prices.
Perhaps this is the reason why some people have issues and some don't.
Maybe they had a few bad batches of inductors or ceramic capacitors from a supplier that are noisy?
Maybe that's why some people have problems when upgrading their OS and some don't.
Foxconn isn't the only manufacturer they use. Not all iPhones of the same model have the same components inside.
They used to, and they used to be known for quality, stable devices. Since the supply chain diversification they're coming out as less stable, like everyone else.
Ceramic capacitors can make noise too. They can act as a microphone too, injecting noise in to a circuit if they're vibrated.
It's just your phone, judging you.
Reminds me Dell XPS laptops. Dell says that's normal and not a problem. Apple will say the same. Their official forum has like 60-pages thread about this.
... the phone is used underwater, w/ the headphone jack connected to the lightning connector at the same time that Bluetooth is connected to the earbuds? No wonder it would hiss!!!
Bought mine new in the box for $99.00 and considered it a steal since it was the best made, last quality made iphone there will be. Enjoy your i6 and i7 junk suckas.
I was just recently researching Dell XPS laptops which are notorious for this, and some of my thoughts were "That's why you pay more for Apple hardware I suppose, they'd never let anything with coil whine out of the door"
Oh the times they are a changin'. That's why I don't buy their stuff any more, you're no longer paying more for better quality (which IMO I genuinely think used to be true, for a little while). You're paying more for the same old crap as everything else. Back to paying normal prices for the same old crap instead, thanks!
Well ok, not under load, but when scrolling the display in any capacity. Noise comes from a chip just near the volume rocker. I've got pretty good hearing for 38 and it drives me batty if I use the thing in bed on a quiet night. I was almost tempted to return the thing to be honest, my iPad air 2, no such issue.
(It's more of a hiss / hum in one)
I played the video in the guys post. Was I supposed to hear something? I didn't.
iPhone already emits enough thermal noise to be picked up from an AM receiver. You can even use it as a music transmitter.

The iPhone 7 works even better than the previous models.

Heat pipe
Your wallet deflating from purchasing an iphone.
It doesn't blow up because it's venting pressure before an earth shattering kaboom. If yours isn't hissing, beware...
You're not listening to it right....
Sounds like a power supply that's on the edge of stability. Everything looks hunky dory until you get a batch of parts in on one end of the tolerance. Or tolerance stackup pushes it into an unstable region.
Could also potential be piezoelectric, where excited capacitors actually deflect and act as transducers.
I bet someone is going to analyse the noise and derive data being computed by the device from it.
They turn into Gremlins
The phone was designed by the Reptilian Jonathan Ive. No wonder it hisses. Can anyone confirm the rumor that he has horns and a vestigial tail ?
Apple has decided that the hissing adds to the user experience.
Because, well, courage!
It should be required by some law to include hissing level in device's specification.
I expect device without moving parts to be silent! How can I buy anything these days at all? Every electronic shit you buy comes with more or less hissing sound, wtf? I'am supposed to pump glue in every shit device I own? Can't it be done on the manufacturer side? Is it considered a defect?
In my opinion it is not normal for laptop, phone, charger or any device low power device, except if you are running some kind of powerplant at home.
I feel like we neeed some hissing device database, otherwise there is no way to know before buying.
The phone wants to remind you that it could explode under the current circumstances, but chooses not to.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
Soon enough, you'll hear a vague whine *all* the time. :/
Turbo Mode .. (hissing from nano turbines)
