Preheat cabine

[matejF]

Doest the preheating the cabin from the app drain the battery or will it use the charger if the car is plugin?

One will cancel the other out if the battery is on charge at the same time, in other words, you'll be putting as much in with the charging as you'll take out with the pre-heating. But pre-heating doesn't actually use up as much as you might think, probably less than 2% for 10 minutes.
