About a week ago I started having issues with the battery charging very slowly. I was traveling at the time and chalked it up to car chargers and other issues with non-standard charging equipment. However I've been home for a few days and have been using my "super speedy" Samsung wireless charger, which prior to this worked great. Now I can leave it on the charger overnight and it will maybe get up to 50%. Putting the phone in safe mode offers no improvement in charging times. Right now the battery is at 30% and the projected " time to full charge, which will never happen, is 4 hours and 7 minutes. Thoughts?
