New update : now it's throwing up a notification that it's "fast charging" and when I press the home button, it puts up the notification that it might default to slow charge if the correct charger isn't used (it is on the correct charger)
I have fast charge disabled as well, so this is even...
Yes, the charge port is clean, and I have cleared the cache in recovery, no luck, it still says "charging" in the lower quadrant of the screen, flickering off, and then showing the battery icon typically in the top right, down in the bottom middle.
