My lenovo legion laptop lets me limit charging to 60% for maximum battery longevity

You’re thinking of cars, industry and others that have high value batteries.

Power tools, smartphones etc charge to the maximum 4.2V/cell, sometimes even 4.3V (some chemistries safely allow it) because the average person just wants the maximum runtime and will replace the equipment before the battery degrades significantly.
