I was just thinking if you are on your computer anyway would it just use some of the excess electricity that your computer would have wasted or would it be worse than charging your phone from a charger while using your laptop separately.

I’d like to remind everyone of the “vampire effect” of wall-wart chargers - if you just leave them plugged into the wall waiting for you to connect a device, you’re constantly wasting a bit of electricity. That should also be involved in the efficiency decision of using the already plugged in computer or laptop.
Someone correct me, but unless your charger is warm to the touch, this is a very insignificant amount of power a year.
Your TV pretending to be off probably draws more every couple of days.
