    This week I got a new car, that has Android Auto integration.

    I am sure I'll have a few future deeper questions I can't figure out from reading and research, but I have two basic ones now:
    1. Is Android Auto, running on a phone not connected to a cable, a bad battery drain?
    2. How do I configure Android Auto on my phone, to launch ONLY when connected to a cable?

    The background:

    Today I left my house with the battery at 98%, drove 20 minutes to a meeting, and when the meeting was over an hour later, I was down to 68% battery life - a 30% drain in 80 minutes. I've never seen anything like that before with this phone.

    Was Android Auto, autolaunching and running on my phone, no cable, the culprit? I do have Android Auto configured to turn off the screen in accordance with my phone's settings.

    Especially if running uncabled Android Auto drains the battery, I'd like to configure the phone to only launch Android Auto when connected by cable in my car. But I don't see a setting for this - how do I do this?

    I don't have battery drain with USB unconnected.

    I don't think you can in the app. Tasker is a complicated way, probably simpler apps to do similar on play store

    Does your car have wireless Android Auto or something? Otherwise, AA is only launched via USB connection. Unless you configured the AA app on your phone to auto launch then it sees your car's Bluetooth signal which you should not do if your car has AA.

    Also, you should be able to see which app used all that battery. Why do you think it is AA?

    Apologies, I'm still learning all this.

    I believe my phone app was seeing the Bluetooth and launching, so I've turned that off.

    AA doesn't show up in my battery usage. I just have no idea how I lost 30% of a battery charge in 90 minutes, unless somehow the phone display was turned on in my pocket all of that time.

    Low cell signal or a rogue app can do that.
