My problem is that my battery case has stopped charging along with my phone. Phone only charges with high wattage chargers, and phone case only charges with low wattage ones. Still get like 3 days charge on the case, but now takes like 16 hours to fully charge. Also, taking the phone case off so much eventually opened the back of my S20fe. Fixed that with S7000.
Cleaning can still help if it only slow charges (if you mean it used to be able to use high wattage ones).
Gunk prevents a strong connection, which can mess with the handshake. Charger will say, “yeah, I can fast charge, check out these amps!” but not all of it gets through and the case will decide the charger is a liar and just go with slow charging. Don’t assume that something getting through at all means the connection is fine because USB has fallback options when conditions are sub-optimal.
