Is anyone else experiencing an issue where the shield icon and battery percentage are sometimes "stuck"?
For a couple of months, this will happen occasionally. I will take my phone off the wireless charger in the morning, and the shield icon and 80 percent battery level will persist for hours. A reboot will resolve the problem, though, removing the shield and showing the true battery charge level.
Strangely, the phone also seems to think that it's still connected to a charger during this time. When I go to Settings -> Battery, it says "Done charging" as if it's still connected to a power source, despite it no longer being on any charger. After the reboot, it will say "Not charging" instead, which I think is the expected text to see when not connected to a power source.
