Do I have to plug off a power cord after 100% charge for a battery lifespan ?
One day I heard that for a battery lifespan, I didn't have to use a charger after a laptop was fully charged.

10 people you ask give you 10 different answers.

If say, if u continue to use it, keep it plugged in, but if u are done for the day or u gone for a few hours, go ahead unplug it.

Best to unplug it when battery is charged, until battery needs charging up again. That way you can't really go wrong.
