Android Auto - high battery drain and GPS issues

[Jdrudd2]

Over the last few days, after installing the beta software, I have noticed my battery draining very quickly. I used to get 13-15 hours easily in a full charge.

Lately, after pulling the phone off the charger at 7am, I'm down to 50% by 11am.

What I discovered is that Android Auto is sucking down my battery. I've also noticed that the icons in the upper right of my phone (S21 5G) toggle rapidly. It appears to be the GPS icon flashing off and on constantly while using Android Auto.

I am not sure how best to document this for you, or give you examples. But the bottom line is: the issue began after installing the beta software. I've done the cache wipe in recovery mode and that didn't fix anything.

As an experiment, I did not use my Android Auto yesterday and my battery lasted closer to 14 hours. 

Hopefully this can be looked at in more detail by the devs. Thank you!

With Spotify is the same problem. In 3 hours of use of 100% pass to 34%

I am betting it is related to the documented Bluetooth issue.

Was having serious issues with battery until I cleared my cache

Mine drains really terribly when I use Bluetooth streaming, but really my battery has been draining really really badly since downloading the beta

Now into third beta, and unfortunately it seems that Android Auto continues to drain battery even after the phone disconnects from the car. I'm using Android Auto wirelessly, and I've noticed a consistent high background battery use by Google Play Services after using my car. Google Play Services usage is high, I believe, because Google Maps (navigation) stays active (navigation notification continues to appear), and this seems to be active because Android Auto has not stopped running in the background. I've managed to decrease the Google Play Services battery drain by force stopping Android Auto and Google Maps after I exit the car. I'm not 100% sure, but both apps seem to start up again by themselves unless I restart the phone. I suppose I could restart the phone every time I get out of the car...but there has to be a better way. I'm using the S21 on TMo, third beta, I factory reset my phone after installing the first beta. I leave my Bluetooth radio on all day because I have my phone connected to my Chromebook when I'm at home, and I use Android Auto when I'm in the car.
