If I turn the pixel off and plug in a cable I get the percent charge surrounded by a starburst and it will charge to 100 percent. But when I turn the phone back on, it will no longer accept a charge.
I had a notification that the USB C port was wet or dirty. Used a hair dryer and was notified that the port was now usable. However it would not show the down arrow in the battery when I plugged in any working USB C charging cable.
