Why does my phone beep rhythmically both during use and while idle.

[AC Question]

My phone beeps in what amounts to timed intervals, but it doesn't do it all the time and it does it both while in use of any kind and while it's idle or charging. Driving me nuts.

Which phone?

Do you have NFC enabled? Is it near a credit card? Is it on a wireless charger?
