When I was in High School I took a  Electric class.
There was a 6Volt Battery , some assorted length wires with battery clips on
each end and some homemade Resistors with wire wrapped around a strip of
Bakelite.
The Teacher gave us Schematics showing Series,circuit to calculate the Voltage
and Current we should get when we assembled the circuit and then used a VOM to
see the readings on the circuit.
 We were told to ALWAYS wire the circuit up first , connect the VOM and then put
the battery clips on the battery.
 When I charge my ell phone I put the USB C plug in the jack on the phone and
then plug the other end in the A.C. socket.
 When it is charged up I unplug the A.C.  plug from the socket and remove the
USB C plug from the phone
 I know it is only 5 Volts but I do it that way.
 Most folks I see unplug the wire from their phone first , then unplug the A.C.
end.
 Probably doesn't matter, but I'm set in my ways

Most people I know don't bother to unplug the A.C. end.  They
leave the cable plugged in so that they can just plug the
other end into the phone.
And of course I have noticed over at the State Fair they have
charging stations where people can charge their phones if they
get low.  That is just the phone end of the cable dangling out
of the wall box.  The cable is frequently very beat up.
I saw one man walk up, plug in his phone, stand there for a minute
and unplug.  I'm not sure how much of a charge he got.
