Apple to replace batteries on 2016 and 2017 MacBook Pros unable to charge past 1%
Apple has identified an issue that renders 2016 and 2017 MacBook Pro models unable to charge above 1%, saying it will replace compromised batteries for free.

Outlined in a support document on Tuesday, the problem also triggers a battery health status warning that indicates "Service Recommended." Apple says a "small number" of 2016 and 2017 MacBook Pro computers are impacted by the issue.
According to the support document, the following 13- and 15-inch MacBook Pro units are affected:
Apple earlier on Tuesday issued a macOS update, macOS 11.2.1, to address the problem and prevent it from manifesting in machines that are operating normally. The company instructs owners of the above Mac models to update to macOS Big Sur 11.2.1 or later or install the macOS Catalina 10.15.7 supplemental update.

Will my current laptop have the same sort of issue in the future? TBD.
Couldn’t time the laptop replacement right for Apple Silicon, unfortunately: oh well!
I'm curious as to where the battery problem lies.
We do know that Apple has a diverse supply chain and they keep a detailed record of every part that comes off the assembly line. That is, they've implemented W. Edward Deming in spades.
So, some batteries had a flaw, so they modified MacOS to adjust for that flaw. Or it's some circuitry which has the flaw, and they've made the adjustment in MacOS to compensate.
It's way beyond my pay grade, but this reminds me how engineers can adjust for problems Mars Rovers are having from the comforts of home.
