Iphone won't charge what do i do?

Ok so my iphone is fairly new and it won't charge for some reason but when i plug it up to my laptop it charges. It won't charge in a wall outlet and i don't know why its really frustrating me and i just bought a new charging port for my phone and it won't work

I'm guessing you tried many different wall outlets to see if it worked. When you say "new charging port" do you mean a new Apple USB Power Adapter?

You may need a new one of these because this thing is what changes the wall power into USB power. That may be why it won't work in walls but it does in your laptop. The iPhone gets USB power from the laptop, but it can't get any USB power from the wall. If you did get a new one, then your wire might be broken and it won't take in and changed/converted power. It would be a good idea just to buy a whole new wire and power adapter altogether and try that.
