My iPhone says it's charging but it isn't?

I plug my iPhone 5 into the cord and it has a lighting bolt next to the battery sign but I left it there for an hour and it's still on 13%. It's a new cable cord and it also says "this cable or accessory is not certified and may not work with this iPhone" but it's an iPhone charger. I'm pretty sure. What's wrong with it?

IPhone 5s won't work properly?

My iPhone has never had any problems until this morning when the screen wasn't lighting up after I clicked the unlock button on the top of the phone. It worked ok for a few hours, but now whenever I try to make the screen light up, there's a ten or 15 second delay. Once I get it open and unlocked, I can use the phone properly. Does anyone know the cause for this issue or a way to fix it?
