iPhone Not Charging When Plugged In? My device is simply not charging while connected to my Windows 8 system. I've heard of my friends having this issue too. There is no connection issue, my computer recognizes it is plugged in, but I don't think it knows what it is and it clearly doesn't allow for charging.

What could be causing this?

not all ports on PCs have enough power for especially Ipads.   Try USB port at back of PC (ones directly connected to motherboard, instead of front ports or keyboard ports.   Front ones frequently have lower power delivery specs than back ones.
