The logic isn’t flawed, your priors are. You’re assuming that people are constantly on a cycle of charging their battery to the limit, running it down low, and then charging it again. If you mostly play docked or with a charger plugged in then capping the battery at around 80% prolongs the battery runtime for when you do turn the limit off and want to use the full battery.

If you mostly play fully charged and stationary, then lowering the charge limit means you have more future opportunities to experience the fully battery runtime when you disable the setting.

I enjoy these every time they make it to my feed, thanks for making them.
