I have a sneaking suspicion that the Tesla Model 3 does not actually have a battery warmer, unlike the Models S and X. Tech support was silent when I asked. On the S & X, the Climate mode of the app shows a battery warming icon along with the heater and seat warmers, but I've never seen that on my Model 3 app.
So if there IS a battery warmer circuit in a Model 3 how do you turn it on, and if there ISN'T then does just warming the interior somehow transfer warmth over to the battery?
