I left my 2016 Macbook Pro plugged in most of the time.  Thirteen months in, it refused to charge the battery  (no Apple Care).  I took it to my local Apple store where they diagnosed a bad charging circuit and noted that the battery only had something like 10 charge cycles on it.  They somewhat apologetically charged me $700 for a full motherboard replacement and advised me to charge it more often before the replacement warranty ran out.
