Yes it will be cut , just wait ... I was also curious. I stayed inside the car and closed it via the remote control . Then, after maybe 2 minutes the led turns off and I can't find the wifi of the adapter anymore with my phone and obviously android auto connection is not available.
Btw: after my test I opened the door manually and the alarm 🚨 turned on... This works also very well
Thanks for confirming pal. I was really anxious if it would kill my battery. I will try as suggested without the alarm part(already did that)
