Mine arrived at the same time as yours and had issues with both the battery and the m.2 port, Valve did an rma for it a few months ago. If you’re in the EU, then you have 2 years of warranty instead of 1.
I would start off with trying to recalibrate the battery, but since it’s probably impossible in your case then just make sure none of the internal connectors came off, then try Steam Support again if that’s not the case.
