Late to the conversation but I'm not seeing this answer anywhere here..... There are three ways to connect your phone to your truck; USB, Bluetooth and WiFi. If you're seeing Waze in Car Play and your phone is not plugged in, you're connecting through WiFi. This combined with Location Services (GPS) used by Waze WILL pull your battery down faster. I suspect that Car Play is starting the Waze app even if you had it shut down before starting the truck. To stop doing this, Go to your phone's WiFi networks and delete / forget the trucks WiFi network. Doing so, you will loose wireless Car Play services like Waze but you can still play music and take phone calls. And Bluetooth has a much lower demand on the phone battery. If you really want Waze or other car play services, you can always plug the phone into the truck's USB. One more thought about your truck's USB. It only provides the 2.5 watts of power specified by the USB 2.0 specification. That means your phone will only have the slow charge option available and the combination of GPS and WiFi will consume a significant portion of that. Unfortunately, it appears that the USB C outlet has the same limitation. Hope this was helpful to someone.

New to me 2021 Silverado 2500 LT I use an Android phone and was able to install an AAWireless dongle giving me Android Auto without having to take my phone out of my pocket. https://www.aawireless.io/ Cost me about $90 on Amazon.com. I do recommend getting a USB 90 adapter so the plug in for the AAWireless dongle does not stick out. https://a.co/d/bz6NMkM A bit of double stick tape keeps the dongle tucked up under the dash, out of sight. Now when I get in the truck automatically links to my phone and displays Waze navigation.
