Heat pumps are more efficient but they still eat battery and the colder it gets the more they have to rely on resistance heat.
Around freezing they pretty much only use resistance heat to warm the compressor oil, but as the temperature goes down and heat demand goes up a resistance grid kicks on more and more to get usable heat.
For my leaf if I can install a diesel fired coolant heater I can stay nice and toasty and not eat up range.
