Android Auto's background scanning for Bluetooth and Wi-Fi signals can lead to significant battery drain, especially for users who do not frequently use the app. This issue affects users with older vehicles or those who commute without a compatible car infotainment system.
Managing Permissions
Android Auto utilizes the Nearby devices permission to constantly search for compatible connections. This scanning continues even when Bluetooth appears off, potentially draining your battery throughout the day. To mitigate this, users can revoke the Nearby devices permission by navigating to Settings > Apps > Android Auto > Permissions > Nearby devices and selecting 'Don't allow'. This action keeps the app installed and usable for manual connections while conserving battery life.
Disabling the App
For those certain they will not use Android Auto, disabling the app entirely is an option. On Android 10 and later, this can be done by going to Settings > Apps > Android Auto > Disable. For Android 9 and earlier, the option may be to Uninstall, which only removes updates. Disabling the app prevents it from launching automatically and stops its background battery usage.
Revoking permissions or disabling Android Auto does not affect core phone functionalities such as standard Bluetooth connectivity, Google Maps, music apps, or hands-free calling. These features will continue to work independently of Android Auto, though they won't automatically display on a car's infotainment screen.
