Can I Charge My Apple Watch 4 Overnight. Also since the fi. They do not like to sit at high charge levels for hours on end overnight.

If your Apple Watch isnt taking any charge dont throw it away. I leave it on the dock overnight and use nightstand mode. Once they hit 100 they stop charging.
Thats why you should keep this in mind while charging your iPhone overnight when you cant monitor its temperature.
SUBSCRIBE Turn On Notification Bell. Its really bouncing between 100 and really 100. Major problems with the Apple Watch. We all talk about fast charging the iPhone but what about the Apple Watch.
