In six months of ownership, this M1 MacBook Air has achieved 77 full charge cycles of its battery. It was purchased from the Apple Refurbished stock & when first started up had zero charge cycles.
Oddly, in that same timeframe I have replaced the USB-C charging cable twice: once under warranty after the first one failed within 25 days and once again, this time with the cable that shipped with the 2017 MacBook Pro.

There’s something amiss with Apple USB-C cables, methinks.
