is it ok to leave the phone connected to usb port once it has reached 100%? Was told that it was not ok and was bad for the phones battery, overheating etc... Bluetooth in the car hasnt been working so the only way to listen to audio is with the phone plugged in to the cars usb port
I believe Samsung's newest phones (S8 and up) have a feature that turns off the flow of power once it reaches 100%. This is to keep the battery from charging too much. Your phone should be fine.
