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

Replacement stock is separate from retail stock. I understood what it was that you reported and did the best I could to duplicate your issue. The only thing I can say that I didn't do was use TikTok and never would have that on my device. I used Music and made several attempts with different music. Anything is possible, but I could not duplicate it on my device. If you do not want to see about a replacement that is up to you. You can wait to see if a software update would fix it. The Genius Bar cannot do anything with retail stock. You could ask the manager if they have a device like yours in stock and you could go in and make the return and purchase stock at the store, but I'm not sure if they would do that. Only the store management could answer that question. Good luck.

I just had this happening with my iPhone 17 Pro Max 512GB. I’ve had it for a week and this is the first time it is happening. If I remove from charger (brand new Apple 30w charger with the cable that came

with the phone) the noise stops

If you returned your first phone, did you specify that you wanted to be informed about the cause of the problem? They probably took it for testing and disassembly.

For those who have already replaced their phones: ask them to provide the cause of the issue. Regardless of whether the replacement device shows the same problem, this should help them analyze the situation if they've collected several affected phones by now. We still don’t officially know whether it’s a hardware or software issue. Keep asking.

I returned my replacement device because it had the same hissing/static noise issue. After that, an Apple senior engineer called me last Friday to gather more information. He said they’re still trying to determine whether the issue is software or hardware related.

He specifically asked me about:

• The charging adapter I’m using
• The cable
• The phone case
• The type of power outlet I plug into

He mentioned he’ll call me again today with an update, so I’ll share any new info here once I hear back.

Also, once they receive my returned replacement device, they said they’ll reassign the limited warranty back to my original iPhone.

I mentioned both issues , the hissing noise while charging from the left speaker and the noise from the top of the phone after launching the camera (especially during video playback). I even shared this exact Apple Discussion link with the senior engineer I spoke to. At that time, he said, “Yes, I can see that people are talking about the issue in the discussion forum,” but unfortunately, there hasn’t been much progress since then.

Today I contacted Apple again because they removed the limited 1-year warranty from my original phone and assigned it to the replacement device instead. I’ve already returned the replacement device, but my original phone still shows “coverage expired”, nothing has been restored yet.

Honestly, I don’t think they’re going to do anything meaningful about these issues. That’s just how I’m starting to feel at this point.

Same issue here.

I have an iPhone 17 Pro Max and when I plug it in to charge, I hear a very subtle static / hissing noise coming from the charging port.

It sounds like a radio static or a light steam-like noise.

The noise is not constant — it comes and goes in short intervals.

You can only hear it if you put your ear very close to the charging port, in a completely quiet room.

I am using the original Apple cable and charger.

Is this considered normal behavior or should I go to Apple Support for a check?

So I returned my phone and asked for another one. It arrived yesterday. I turned it on, updated it to 26.1 and guess what? Same issue. I had 50% battery and no problem. With >80 the static/hissing was loud. I’m on the 14 days again so I will return the phone until I get one without it (if there is one).

I have talked to Apple support to for a while and the next step is now to replace my device. The replacement device will reach me the next days. But I expect that it will have the same issue. Will be interesting what they will say to me when this happens with the replacement device too.

All of the new 17 pro and pro max have this problem. There are a lot of people that didn’t notice and a lot of apple fan boys that don’t care. We were called “people with OCD” because this problem is barely noticeable and that doesn’t make the phone unusable….no comments. I replaced 1 time, same, I’m waiting for the second third phone now but will arrive with the same problem. The thing is I have to return my old phone so I can’t replace it forever

Same issue here. It is the most noticeable when opening an app, especially high performance game.

Also, when recording video it makes that noise but only on the 1x lens. If you change to any of the other lenses, it quietens down. Just so insanely irritating. I hope they can issue a fix 🙏

@VictorSerban can you check to see if you're getting any noise from camera plateau when you open the Camera app?

Me too. Just noticed it now, phones on charge (but at the 80% charge limit) watching a YouTube video. Was hearing a faint wheeze/whistling/hizz noise. Upon locking the phone it seems to stop (after it getting a little louder for a moment), and when unlocking it sometimes restarts or need to play sound for a few seconds and pause to hear it continue.

I have this too. Noticed it a couple of nights ago and thought it was my bedside table light about to pack up. So annoying. If they can’t issue a fix I’ll go back to my 13PM and get the money back as it’s even audible on video recordings in quiet scenarios

That's good! I had a second scheduled call today, and they escalated my issue further, collected extended data from the iPhone, and forwarded my recordings of the noises. This is likely a software issue. It will take about four days to get a response from the developers.

The only thing is, I don't know what will happen with the noise coming from the back of the plateau (Camera), because the Apple employee prioritized the sound from the speaker next to the charging port. I'll definitely keep an eye on this.
