Is it true that Bluetooth drains a smartphone battery significantly?

Partly. One source advises disabling Bluetooth to reduce smartphone power consumption, and a forum answer says keeping the phone on for Bluetooth use burns battery quickly, while another user reports a Bluetooth connection did not noticeably hit phone battery life. None of the items quantifies the drain, so the evidence only partially addresses the claim.
