Using AndroidAuto phone gradually loses charge

[chisnz]

On every other phone, using them connected to the car via USB gradually charges the phones.

With my Mi10T Pro just running AndroidAuto on the same car causes the phone to lose charge. I'm using stock 12.0.7 international.

Anyone else having excess battery drain while using AndroidAuto connected to a car?

Now working ok - phone gradually accumulates charge while using AA connected. Took a few reboots and that seems to have solved whatever was eating battery.
