    I noticed yesterday, when I put my iPhone's back to my ear I can hear sizzling and crackling noises. It increases when I open up apps, load webpages etc. Not only increases but even the 'habitat' of the sound changes.

    Turn the phone off, and make an appointment with the Genius Bar at your local Apple store. They'll be able to assist you further.

    This thread is 2 years old. Can you explain the issues you're having? Which iPhone and OS? What noises do you hear? Does it come from the speakers, or somewhere else?

    Hello and welcome to iMore. I'm sorry that you're having issues with you 5s. As @Sherry_B suggested, you should turn your phone off, and make an appointment with the Genius Bar at your local Apple Store. If you don't have an Apple Store nearby, I suggest you contact Apple Support. Click here for a link.

    Hi! yes it's an old post, but it's the only one that explained exactly the same problem as me. When my iphone 7 is on, and I put my ear on the back of the phone, near the apple logo, I can hear some sizzling and crackling, kind of like the one that computers make sometimes when running software. I dont know if that's indicative of some malfunction, or is a common thing that I never paid atention to it before. But according to my brother (he has a iphone X) he did the same thing and he couldn't hear anything.

    Problem is that where I live (Chile), the local Apple Store is not an official one, just a "premium reseller". So when I wanted them to take a look at my phone, they told me that they don't make technical support to phones that aren't covered by a guarantee (my phone has like 2 years of use now).

    Have you tried restoring it as new, not from a back up? If it's a software issue, that might work. If that doesn’t work, then it's hardware.
