I dropped my iphone 5s in water. What should I do?

I just got it last month. It was there in water for 4-5 seconds. I switched it off immediately n dried it with a cloth. I could not put in rice or silica gel or blow dry it for 3 hours. Now I hv put it in rice. I want to know if i should remove my battery.
what can apple store do about it if i tell them honestly what happened?
I purchased my phone from Kuwait but right nowwm in India.
Thanks in advance.

Added (1). Well i dn knw to open the battery myself n I dnt want to take a risk giving it to some random mobile shop here. Thats why I want to go to just Apple store. What shoul I tell them I dn knw.

Remove the battery and place it in a container filled with rice. Wait about 3 days and it should be fine.

You haven't told us if your phone works or not?

The apple people will know - when they open up your phone that it was dropped in water so you may as well be straight with them.

3 hours is nothing, let it sit 3 days with it off. If it doesn't work after that then take it to an apple store.
