pixel watch 2 oddity

Okay considering what I've read so far this may not be as odd, but it's still strange and disheartening.

Short and sweet: for 2 days my Pixel 2 Watch on the included charger would not charge past 47%. I puttered around online and turned off the battery saver as suggested. I rebooted the watch and it went from 47% to 0% and has been apparently totally dead (no green heartbeat sensor flicker). done reset, factory reset, upside down spinner reset, and threw prayers to a few Eldritch Gods in for good measure. I have a new charging device coming today but is that just another $40 down the tubes on this mess? I've not even had this a month so this is so very not amusing and Google's online says I have to report it to T-Mobile since I got it from them. Joy.
