Did I short circuit my iPhone through water damage?

I tripped and fell into the pool with my iPhone 4s in my back pocket. I immediately picked up the phone and handed it off to my cousin outside of the pool, and we put it in rice overnight. As I was handing it off to her, I noticed that the phone was surprisingly still on the unlock screen instead of being black, but just as I tried to unlock it, it shut off. We kept it in rice overnight, and I just now got home from her house with it. It was completely unresponsive, so I plugged it into the charger. The apple logo appears, my phone loads to the unlock screen, and I unlock it. The corner says that the battery is only at 1%, so I know that it must have been stone dead. Everything seems to be fine except the screen is slightly blurry in the corners, and then it suddenly shuts off. The next few times I tried to turn it on via the charger, it has been unresponsive. Did my phone short circuit? Or is there still a chance that it will work after being in the rice that I put it in for a little longer?

Its toast, the rice trick doesn't work on iphones.

While rice may have helped, turning the phone on and charging it, in less than 72 hours, has pretty much doomed the phone.

Also the chemicals in pool water are very corrosive to the metal electronics in the phone. Bleach/Chlorine and Salt are the worst things other just just plain H2o that you can have come in contact with the inside of the phone. Even once it is dry, the chlorine will continue to corrode the metal in the phone. Had it been saltwater, the salt crystals would start ground within 8 hours and pretty much would destroy the phone. Which would need to be flushed out of the phone first, before drying.

So if this were a regular pool or a salt water pool, it would be best to take the phone to a cell phone repair shop to get it properly flushed and dried. (That is what I would have done if I didn't have a desiccant at home other than rice, to dry the phone)
