iPhone 17 Pro Max – Static / hissing noise from speaker while charging

Hello everyone,

Also my brand new 17 pro max 512 make a grey noise when plugged in and I open the camera app.

I contacted a senior support engineer in apple using the official channel into the apple support app.

They called me and completed a full hardware diagnostics.

They tell me that Apple is aware of the issue and they are working to release a software update (by diagnostics there isn’t hardware fault).

Apple ask you to choose, wait for a software update or replace the phone (I rejected this solution, because of software issue. Also the replaced phone may have same noise problems).

My case is still open, and if the future software update doesn’t work they recall me for other options.

I swear these information are useful for the community :)

so… waiting the next buggyiOS26 release ;)

Same problem. But to test it people have to use their phone, open apps like TikTok for example, but with sound lvl 0 (no sound, off). If your phone is plugged, and even more if you’re charged at max level (with a limit or not doesn’t matter), you will hear the buzzing noise from the left speaker even louder. It’s like if the speaker was on, able to produce sound, but since your sound level is at 0, there’s just a hissing noise. If you scroll TikToks with no sound you will hear it even more. Phone off, or just on but without using anything or any apps, it will still be there but in a faint way, barely noticeable. Try again please. Of course in a quite room it’s better.

Okay Update #1 my Anker MagSafe battery was the issue only happens after music or video stops playing but if nothing is playing and I pluck the battery it hisses but after playing video or music it sounds like Morse but very rapid my brain thinks it could be the coil sensing feature that pulses to detect the phone same as the blocks that you’d connect your type c

same here, iphone 17 pro max deep blue 1tb. Its coil whine from charging circuitry being picked up by audio circuitry. Its due to poor isolation of the audio circuitry. Manufacturing defect. Only way they could fix it is to mute speaker when no audio is being played like a noise gate, however problem will persist while quiet audio is being played. I cant see a fix for it , And they wont do a recall as it would cost them too much. For a $3000 phone its unacceptable.

I got in touch with customer support, and I was told that this issue is 'expected behaviour'. Sounds like Apple is not planning to fix or even address it further.

Replacing a device does not reset the buyer's remorse window. I didn't want to take the risk, so I have initiated a refund right away.

i just had the same problem but it turns out it was Snapchat that was playing even though it was closed as soon as I opened it up I saw a video I recorded last night still playing, so maybe check apps that were used even tho they were closed.

I had a similar issue a couple of generation’s iPhones ago and it quit when I plugged into a different outlet. Found out the outlet box was defective.

I’ve experienced the same static / hissing noise issue with my iPhone 17 Pro Max while it’s charging. After I bought the device, I contacted Apple Support and they arranged a call with a senior engineer.

A couple of days later, the same engineer followed up and said the recommended solution was to replace the device. She made an appointment for me at my nearest Apple Store, but when I went there, the Genius Bar team said they couldn’t issue a replacement because they couldn’t replicate the problem in-store.

I contacted Apple again afterward, and they scheduled another call with a different engineer. This time, the engineer also concluded that the best solution was to replace the phone. He processed a replacement order, which required a $1,199 + tax hold on my credit card, but it’s been three days now and there’s still no update on the replacement shipment.

I’ve heard that some other new iPhone 17 units are showing the same issue, so I’m honestly not sure what the best course of action is at this point.

I’ve read on various social media sites that people that have talked to senior support personnel are being told Apple is aware of the situation and is investigating. In addition, they are told that the engineers have not yet decided if it’s a firmware or software fix and they are testing both. Expect a solution in a future update.

I’ve had two devices both the blue and silver 512gb did it on both latest one just been returned as they identified it as being faulty, happens when you scroll and open keyboard etc and 26.1 didn’t fix it, awaiting for a replacement device

I'm sorry, this is the first time that I've seen this. I tried to duplicate your issue with my iPhone 17 Pro Max and was unable to hear the noise you describe. I couldn't hear anything, sorry. You are welcome to contact Apple Support or make a Genius Bar appointment at the nearest Apple Store to have them listen if you can duplicate the issue. If you purchased from an Apple Store, you have 14 days to return the device, no questions asked.

@Apple, can you please officially provide the explanation and solution?

Apple don’t read these posts, they just pay the rent and moderate. Report it as a bug at https://apple.com/feedback and if enough reports are received they will investigate.

I’ve just submitted a report on the Apple page only took 30 seconds. If enough of us do this hopefully they can issue a fix or some clarity on optimising settings to avoid this truly irritating issue.
