In the last two days I've had the green lightning bolt at the top of the screen light up when I have well over 50% battery available (this morning it was 93%) and the green lights on the back of the watch were lit and it wouldn't stop until I force rebooted the thing. I was nowhere near a charging cable at the time. In fact, when this occured I was out in the world, working out or taking a walk or at work. This doesn't seem normal. Anyone else have this issue? I'm on WatchOS 2.01.
