IPhone 4 felll into toilet. Now placed in rice

So my phone accidentally fell into the toilet and it was in there for like a second maybe less. After that i shook it off and cleaned it with paper towels and then put it under the hand dryer to wash it off. I went home and put it into rice for about 11 hours and then plugged it in and now it works when its plugged in but as soon as i plug it out it turns off. It says plug into iTunes when i put it on the charger but when i plug it into iTunes it doesn't do anythiing. It turns on the white apple sign comes up and then turns off and keeps doing that. I put it back in rice to see what happens… What can i do? Is it the battery? Please help
Thanks
(I don't have enough money to upgrade or buy another one)

Turn it off completely if you can and leave it in rice for at least 2-3 more days. If it still doesn't work after that, it's a goner.

It's dead. Say goodbye to your iPhone.

Your best bet is to keep it in rice longer. Avoid turning it on for a while. Try rice for 3 days… If its still the same problem, there's nothing much you can do. It sucks cuz its not like you can open an iphone components… Good luck!
