Dropped iphone 5 in ocean. And turned it on by mistake?

Please help… Dropped iphone 5 in ocean and by mistake turned it on… Tried putting it in rice for 24 hours… Then plugged it to charge and now it displays a black battery without the charging sign…
My warranty is over and my contract isn't due for a while… Any tips? Is there any way to fix this on my own? Any input would be greatly appreciated!

Your warranty would have been of no use, as it does not cover accidents. There's no fixing salt water corrosion. Be more careful with the replacement.

Water is bad, salt water is terrible, while i hope your phone lives, I doubt it will, sorry.
