I dropped my iPhone 6 in the toilet, what do i do next?

It was in the water for a round 10 seconds and i put it in rice after like 7 hours… 2 days later i tried to turn it on and it didn't so i charged it… The battery sign came up for few seconds and then disappeared. I had to unplug it because it was overheating (i couldnt hold it in my hands for too long) its been 4 days now and it won't turn on OR charge. What do i do? WHAT WERE YOUR EXPERIENCES AND HOW LONG DID IT TAKE FOR YOUR IPHONE TO TURN BACK ON.
PS: my mistake was trying to turn it on after dropping it. It turned off by itself.

If water damage was done then rice doesn't magically reverse damage.
