Note that this advice is wrong if you have a device with good software and settings. (aka maximum and minimum charge settings). Smaller more frequent charges are easier on a battery than less frequent larger charges of the same magnitude. Better to go from 70% to 80% five times than to go from 30% to 80% once. Especially on a laptop that doesn't have battery cooling.

Even worse, unplugging your laptop makes it use battery charge, adding additional wear to your battery.

Virtually all EV's have good software, so your electric car should be plugged into a charger as often as possible. It should be the same for laptops, unless you have one that is poorly configured; most are.
