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

On the 12th, I made a purchase for the iPhone 17 Pro, which I received on the 22nd. Upon initial usage, I observed a notably low sound output from the speaker, which is significantly inferior to the sound quality of previous iPhone models.

Apple has offered a replacement device, however, after reviewing this discussion, I am uncertain whether to proceed with the replacement. The possibility of the issue persisting even after replacement remains a concern.

Is this noise coming from the back of the phone, specifically the center plateau? It happens with every lens I use from 0.5x to 8x, but it stops when I exit the Camera app OR, as I've just noticed, when I turn on the Selfie camera. If you can, please report this to Apple Support.

On my 13Pro Max was an issue: when I started record a video, for first 2 second sound is not recording and I heard some buzzing noise on the video.

Apple said that with phone everything is ok and this is software issue.

Ok. During 4 years issue was not fixed

Yes exactly! People on Reddit contacted Apple support and opened a case. Apple developpers will get back to them this Friday, hope there is a software solution.
