When still charging, does it matter if it's unplugged from the wall or from the USB connection?
 
Does not matter to the electrons....

However, I use the wall. Do not like to leave a potentially "hot" wire (any voltage of any sort) dangling from a wall outlet.

Most cables are pretty flimsy nowadays and leaving them dangling is all the more likely to result in physical damage as well - getting snagged, pulled, stepped on, vacuumed up....

 
Hi
Generally better for equipment if you unplug it from the wall first.
If you pull the usb plug during charging you interrupt the current and may cause a spike,if you unplug it from the wall however the voltage will decay slowly as the capacitors discharge and you will not get a spike.
