iphone 5c weird noise

[rendy0212]

I have a white 32gb iphone 5c (AT&T) and its making odd noises at night when the phone is asleep. I have not noticed it happening during the day but there is also more ambient noise so I may just not notice. Also I have only had the phone 3 days.

The noise its making can be heard in the zip file attached. It is the clicking you hear in the background (its faint). There is also a buzz sound when it starts but I was not able to capture that on the recording.

Any idea what is causing this sound and is it normal?

It goes through this several times at night and is loud enough that it wakes my wife up.

Without downloading the zip file (cuz I don't download them), is it possible one of your app alerts is set to trigger the buzzer instead of the sound alert?

No it is not an alert sound for sure. The sound is mechanical in nature but muted and does not come from the speaker. It starts off as a muted vibration and then buzzes almost like a dot matrix printer sound (best I can come up with).

Just a question - do you have anything with a speaker near it? Like a clock radio or anything? It could be radio interference from the iPhone cellular radio (data etc). I've found this sound to be most prevalent on BlackBerry devices, but it's happened with my iPhone a time or two.

I was going to say the same thing. I get the radio interference on my speaker system once in a while.

Never thought of that but yes it is sitting right next to a radio alarm clock.

Thanks for the heads up.

Any thoughts on why this didn't happen with iphone 4 or 4s? Only iphone 5c is experiencing interference issues.
