Phone doesn't charge when connected to chargers.

It always shows the notification that charging connected device via USB, although there is no device connected. When I plug in a charger, it does not charge. But when I open the USB preferences and change the USB-connection to be managed by the pixel and plug in a charger at the same time, it works. I was using this option to charge my phone for a while, everytime I connect my charger i change the setting in USB preferences, now that has also stopped working.

My Google chargers seems to charge other devices so i don't think it's the cable or the charger

I have cleaned the USB C port on my phone and the software is upto date.

The phone charges wirelessly but it's too slow and is not convenient for me.

Kindly help please.
