Octavia 2021 1.4 TSI iV electric A/C unit switch

Good afternoon Gent's.

I'm a owner of Skoda Octavia 1.4 TSI iV for the last year. Didn't had much time to around it, but I have noticed something strange should I call it.

There is any why to change the air-conditioning to use the traditional petrol engine instead of high voltage battery?

The battery level goes down dramatically when used for demisting front and back windscreen and heating seats.

If there is any way let me know please?

And also do you recommend using the app for remote control aircon unit? And another features?

Thank you in advance and stay safe
