Unable to charge my iPhone XR

Is the blank screen because the iPhone's battery is dead?

If it's frozen, then do a force restart

If it's dead because it would not charge..

Are you charging with a cable or a wireless charger?

If charging with a cable, try a wireless charger. If charging with a wireless charger, try a cable.

Have you tried a different charging cable and a different charger? Flip the lightning connector 180 and try again?

Try a different wireless charger?

If still unable to charge the iPhone, grab a flashlight and look up into the charging port. See any obstructions that would prevent the connector from seating properly?

If so, grab something non metallic, like a wooden toothpick (might have to shave it down a hair), and carefully remove any debris up inside the port.
