Coil whine/ticking in iphone 12

Hi.

My iphone 12 makes a noise on the back when I hold it to my ear. It is a type of coil whine.

It is normal?

iPhone 12, iOS 14

Noises coming from earpiece speaker My iPhone 11 Pro max is making weird static, ticking, crackling noises coming from the earpiece speaker. This happens when I’m using my phone, typing, on a call, or even just scrolling on my Amazon app. Is there anything I can do from home to remedy this? If it makes any difference I got a notification recently saying that my headphone usage had been up too high but I only connect it to my car usually.

Extremely loud screeching noise on my iphoneX and ipad I experienced a loud, screeching noise coming from my iphoneX and ipad in the middle of the night when neither one was in use. The sound was similar to a smoke alarm. This sound first came from my iphone, i powered down the phone, then waited a few minutes and powered it up. Ten minutes later the same screeching noise was coming from my ipad. I powered down both devises until the morning when I could search the internet for a solution to this problem. I found many people with similar experiences, dating back to the iphone 6, but no answers. FYI - I recently updated the software on both devised to iOS 14.6. This noise could seriously damage the users hearing if they were using earbuds. Does anyone have an idea on how to fix this problem, or if it is being addressed.

Hi, geo177

Coil whine is normal and isn't harmful in any way, but can be annoying. To explain in more detail - Is this happening when you are charging your device or is this happening all the time?

All the time? Hmm... The noise increasing while you are loading or playing games makes sense, as this would be normal for a computer. However, your iPhone being smaller shouldn’t be making this kind of noise. I would recommend submitting a request to Apple.

Thank you. It happens as long as it is in use, and increases when you are loading or playing
