What do I do with my iphone if it has this?

No matter how many times I turn it on and off it won't go away even if I put in the charger. The circle on the picture is just the Itunes music thing, under it it says iTunes and then there's the charge at the bottom. WHAT So I DO?! It's an iphone 5s by the way.What do I do with my iphone if it has this

The battery needs to be replaced.
Apple fixes it for $100-$200.

The phone is in DFU mode. Hold down the power and the home buttons at the same time, when the screen goes off release the home button and then release the power button and it will reboot as normal.
