Sure; all sorts of data leaves your iPhone in the form of encrypted channels to Apple servers, whether you have telemetry/analytics enabled or not. When you fully power-down your iPhone with Find My disabled, your Baseband modem is still sending and receiving information from nearby cell towers. Apple has created conduits specifically for harvesting and retaining this data, they wouldn't collect it all if this wasn't the case.
Oh, and if you still don't believe me, you should look into some of the more recent PRISM revelations (eg. how iMessage and Find My can be used by law enforcement), or the ways that the CCP uses the data Apple collects for them. There is nothing besides marketing that suggests Apple has a commitment to privacy or security.

That is not what I hear from people who work there.

I'd be interested in references/citations if you have them.
