iphone won't turn on after water damage
Yesterday I dropped my iPhone 6s into the Toilet. It was only in there for maybe a second, and worked fine when I took it out, so I assumed it was okay. The battery on my phone was dying so I plugged it into my charger, and it wouldn't charge, and kept getting stuck on the red battery screen. I left it on the charger overnight and now it's completely dead, and not even displaying the red battery screen anymore, it's just completely black. Help!
iPhone 6s, iOS 11.2.5
