I think this is false. Lithium-Ion batteries (in contrast to e.g. NiMH) do not have the memory effect [1]. It's actually charge/discharge cycles that reduce battery life for such batteries [2]. Older MacBooks were only rated for 300 charge cycles, nowadays up to 1000. This also reflects my experience. In recent years, my MacBooks with the highest remaining capacity have been those that I had pretty much always connected to a charger, only using it on battery during meetings.
