So I plug in my Galaxy S20 into my car charger, and the phone cannot recognize it. I try my backup USB cable, same thing. I get home and plug it into my home charger - same thing. I dink with another wire, it connects - and tells me it will take 4 hours to charge the phone. It was down to about 30% battery - it should take maybe 30-40 minutes to charge, not 4 hours. I looked in the phone itself, nothing, no apps, were sucking battery. I don't surf the internet with it or do e-mail, and a virus scan yielded nothing... I powered the phone off and on, and that fixed it. Just an FYI.
