@valleyfloydroad: Are you using an official Samsung 15W plug adapter, along with the USB cable that came packaged with your device? When you mention that the phone charges fast using c-to-c leads, what are you connecting the lead to? I ask because 'fast charging' should only be possible using a plug adapter, while connecting via USB to a home computer, for instance, should only generate standard charge rates. I understand, however, that you might be comparing the charge rate to the 44 hour charge period you reported.
When you connect your phone to your car via USB, swipe from the top of the screen to the bottom to access your Notification panel, tap on the USB configuration notification, and look for a 'charging' option. Let me know if this helps.
@valleyfloydroad: In the USB configuration menu, you should see an option for Android Auto. If you have recently updated the phone, then this may be why the default USB settings have changed.
@valleyfloydroad: The Notification panel should be accessible by swiping down from the top left of the screen (if you are on Android 15). From here, while connected to your car via USB, you should see a USB Configuration notification which can be tapped on to access further options (as per the above).
Let me know how you get on.
