i had the same problem with my iphone 4s!
it wouldn't charge when i plugged it into the wall OR into my computer, but i tried it with a new chord and it worked fine!
if you've have your chord (the one that plugs into your iphone + an USB slot) for a long time or if you yank on it a lot or are just generally rough with it, it might be damaged
try getting a new chord and it should work fine (since it doesn't seem like a problem with your actual phone)
