My iPhone won't charge. What do I do?

I have 2 chargers that are in working order and pretty much brand new I didn't get them that long ago. I have an iPhone 5 and both chargers were working up until right now and my phone is about to die what do I do?

If both chargers don't work there might be something wrong with your phone.

Then go back to the shop and ask, they might give you new iPhone.
