A:Answer I just had the same experience and found my way here. Someone mentioned moisture detection on the charging port. While it has been a couple of days, and I didn't see moisture on the port, I decided to use my hair dryer and sure enough, a tiny droplet of water pushed out from the side. May have been underneath that tiny clear cover. I used a Q-Tip with alcohol, which supposedly helps draw moisture out and blow-dried it again. Still beeping so I did it one more time. All dry, no beeping! It worked! Charging peacefully now. You can see a teeny droplet of water in the first photo and gone in the 2nd.
