Conditioning for cold weather?

Is it possible to tell the battery and not just the cabin to warm up for driving? So for example I leave for work every day 7.20. I'd tell it to schedual a warm up for 7 15 for both battery and cabin whilst plugged in.

Is thst such a thing? I know the cabin is I just want to know if I can with the battery too?

Someone correct me if I’m wrong, but I didn’t think the Model 3 had a dedicated battery heater? AFAIK it only uses waste heat from the drivetrain to heat the battery. So preheating isn’t possible.
 
I would recommend a simple timer app named Smart Timer, written by a UK Tesla owner.

I use it for heating my car at the end of the work day in winter, of course you can set it to cool the car at a set time.

Plus it has a geolocation condition so in my case the heating only comes on if the car is parked at my office.

The best way to do this is to charge the battery. The inefficiency of battery charging (and discharging) will warm it up.

Increase the charge limit by 5-10% about 30-40min before you want to leave and set it charging. Then switch on the cabin heater 10min before.

Frost cleared, warm, toasty and ready to go when you get in.

Alternatively just live with the reduced regen limits for the first few miles. It’s not a major hardship....

Both of these were my understanding, too.

No sign of this being available for Android, so I cannot try it.

It could be. The first section of my 12 mile drive is a 1 mile downhill. I don't want to waste all that nice regen
 
BTW, according to the manual, using the seat heaters is a more efficient way of heating than heating the car with air. While this may be obvious, it's worth bearing in mind if you just want a quick heat boost and don't need the whole car warming up... and you don't need to do it 15 mins before you leave.

Can you use the seat heaters without the climate control on from the app?

dosnt work for my 2 year old. hes in a car seat he has a blanket even now with a cabin heater on as it takes 20 mins with that to get my current car to warm up enough. im alright I have heated seats and a heated steering wheel (ATM) but he dosnt. so I need a warm cabin as I cant put his coat on as hes in his car seat and he has a tendency to want to drop his blanket.

being bicky here I know but it is two fold. don't want to waist being at the top of a hill and have a duty of care to my child.
