Just started to use internet sharing to use on one P.C. Should I turn the sharing to off (phone settings) when work is done on the P.C. or does it matter?

Yes it would be best to turn internet sharing off after you are done. Otherwise you could rack up some data usage accidentally. Unless you just disconnect your PC from your phone. Then that wouldn't be an issue. I still would turn it off when you are done using it just to be safe that you aren't wasting data and or preventing someone from try to access your internet sharing as well. Might save battery as well but can't confirm that.

Turn it off, not that hard to do, it probably does drain the battery somewhat. Plus as before mentioned prevent others from trying to gain access to your phone.
