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

I’ve noticed a strange issue on my iPhone 17 Pro Max and I’d like to know if anyone else can reproduce it.

When the phone is plugged in and charging, if you play some audio (for example a song, an Instagram Reel, or TikTok), turn the volume all the way down to mute, and then put your ear close to the bottom speaker, you can hear a faint static, buzzing, or hissing noise, similar to the sound of an old radio.

I’ve tested this with both an official Apple cable and charger, and the issue is still present. This sound can also be heard even when no audio is playing, although it’s a bit quieter in that case.

I’m curious if this is a widespread issue or specific to my device.

iPhone 17 Pro Max, iOS 26

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.

I installed version 26.1 RC, and the noise continues. Honestly, I don't understand why Apple is taking so long to acknowledge this problem.

if it’s happening on brand new replacement devices too, is it worth it to replace? I don’t honestly want to set up a new device if it’s not going to fix the problem

Just noticed this today after installing 26.1. Hadn’t heard it before that (could be a total coincidence, though my brother said the same after 26.1). Hope it’s a software thing.

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

@MakeReal Does your replacement device have the same problem?

I have the same problem with my iPhone 17 Pro Max 512 GB. At this price, it is unacceptable for something like this to happen. Is there an update from Apple?
