Charge in cold weather

These (apart from the cabin heater) are powered by the 12v battery and not the HV battery and won't materially impact range calcs.

For this reason Porsche recommend the use of seat heating and steering wheel heating before increasing cabin temperature using AC / cabin heater.

Impractical i know but given the car's reduced range in winter every little helps.

The 12v battery is recharged from the HVB during a long drive though, so it still comes from there, impacting range.

But yes, those consume less power than the cabin heating does. Which makes sense since they don't keep you nearly as warm either. Personally, I can't do without cabin heating unless it's just a little cool outside. If it's cold, my feet and face get too cold without cabin heat, even though my back, butt, and fingers stay toasty.

I had a BMW iX, as a loaner. Hated it. Except that it heated both armrests, so door and central console. This was very very nice. Rest of it was truly worst car I've ever driven. But heated armrests should be a thing in EV's.

12v has to be charged by the HV - that's obvious - but the impact on range when using the 12v systems is not materially impactful to the overall range. The heater is the killer - 800v HV heater. Add to this impaired battery performance in colder ambient and poor weather then you have the perfect storm.

The only saving grace is the increased usable HV battery capacity to "hide" the range sapping HV dependent systems.

Not *as* impactful because it doesn't provide nearly as much heating, yes. Feet, legs, face, etc still stay cold. A cold cabin will save some power, and thus save some range.

On a recent road trip, I had a 211 mile leg in 25F temps that didn't look like was gonna make it (cutting it really close). I turned off cabin heat for a while. The arrival % on the Porsche nav immediately jumped 4%.

I dropped from uk miles 320 to 249

Comparing summer months to now?

Yep - pretty drastic and short journeys (as per ICE) will see your consumption rise notably.
