What's your definition of "pretty minimal"? FaceTime has noticeable battery usage in my experience, but it's not excessive. I'm not sure how it compares to unencrypted video chat, but I doubt it's much higher. Crypto is typically accelerated in mobile devices these days. I would guess that the screen and network (Modem/wifi active all the time) are the battery-draining bits, and while encoding and encryption don't help, they're hardware-accelerated. That's only a guess, though, and I'd appreciate it if anyone had data on this.
