Strange high pitch sound every hour

[washburn]

I noticed I’m getting a high pitch sound like a beep every hour 19 minute mark to be precise, the sound is not any sound file but like a system speaker sort of sound, lasts for a second

Dunno if I should exchange the phone, never had anything like that before with any iPhones

What could it be?

Hard to guess without hearing it. Try doing a recording just before it happens. Post it.
