Does it mean plugged @100 results in trickle charging ?
We don't know, we haven't specifically tested it. It doesn't display the shield UI without the limit toggle enabled outside of the special case deployed for the Pixel Tablet stand earlier where it stops at 90% which is a bit odd now. It interacts a bit strangely with the charge limit toggle such as it not being able to recalibrate until it's charged normally without the stand so it will start going to the 90% limit with the stand until it's charged another way.
