I've been having this issue periodically of my Pixel 6 pro running GOS (latest build).
I have several chargers and USB cables that were all charging normally. Then gradually i've run into the problem of plugging in my phone and it not charging.
The battery screen under settings show "Connected, Not Charging". Rather annoying because if I unplug and plug it in several times it will eventually accept the charger and charge.
Does anyone have any suggestions on how to overcome this? Already cleaned the port with zero luck.
