IPhone 5 charger is messed up?

So I have the iPhone 5 that I got for Christmas last December & the charger is messed up. I would plug it in & it won't even charge unless it's in like a certain position & now it doesn't even charge like at all & it's really annoying because this is already my second charger. Anyways, I know that it has a one year warranty so if I take it to sprint & take the first charger that I had which is also messed up can they give me a new one?

That happened to me. It's a charger defect I think. I just bought a new one and I don't have problems with it.

Unfortunately one problem that Apple has to address is the quality/durability of their charger cables. I just yesterday bought a new Lightning cable for my iPhone 5 (2nd one) after the 1st one gave out & last year had to buy a charge cable for my MacBook Pro & even before that cables for my iPhone, iPhone 4 & iPod classic.

As far as what you could do, I'd just buy a new one & done, or you could look for a stronger aftermarket one. Amazon may have some of these. If you do end up going back with an Apple one try to be as careful with them as possible to extend the life of it.
