Is the precondition on the way to an EV charger a thing now?

I seem to recall reading somewhere that if you set a charger as a destination it will precondition when you get closer?

Is that anything that needs to be turned on or just something that the car does now?

Edit - Read patch notes. Seems to be a thing that just works now when a DC charger is set as a destination, was just checking as we have a big trip to Scotland coming up.

If it works as it should, the car will automatically start warming the battery pack as you navigate to the DC charger. Even with this it's not a magic bullet that will suddenly heat the battery to optimum temperature, but it helps.

The other way to really give the battery a good warming is in the last couple of miles floor the car as if you were an F1 driver, and then immediately come off the loud pedal for max regen. Repeat this until you reach the charger. You and any passengers will feel as sick as dogs abd I don't suppose it's very good for the rest of the car but it's an option o_O

Needed to charge using DC over the weekend for the first time, 40 mins out got the alert, and then was surprised how much extra battery was used in those 40 mins - my arrival SOC dropped by around 7% on both occassions, despite the driving conditions and speed hardly varying.

Top speed I got was still only 143kW on a 350kW Gridserve charger at a starting SOC of 23%.

Charged 3 times and very similar results, although on a 180kW Applegreen it only started at 90kW, but when the other car sharing the charger moved away it went up to 135kW.

I got to try the preconditioning yesterday. I got the warning around 30 minutes before arriving at the charger (in this case a Tesla V4) but no indication of it happening after that (a simple icon in the dashboard would help). I arrived with 11% and got to 60 something in 22 minutes. With 200kWh peak and mostly around 150kWh. In total 53kWh in 22 minutes.

It's true that the consumption for preconditioning got my battery lower than expected (around 5-6%), but I also notice an almost 10% discrepancy between the estimated and real before getting home, not related to the preconditioning but weird anyhow because until now it's always been on the range of 1-2% difference.
