Is it better to remove the cord when the phone is fully charged?

pu1. It's better to take it off. It could be overcharged. Even if it's not, it's connected, so it's not a lot, but it keeps eating electricity

OK

pu2. It's meaningless now, but when it's fully charged, it doesn't charge anyway, so there's no big electricity.
It's not that I don't eat at all, so it's good to lose weight
