Chosen Solution

I have a I phone 6s plus that went for a short swim in my pocket. I have opened the phone and dried out all the components and cleaned the connections. I didn’t see any corrosion on the connectors. The phone still doesn’t fire up at all, and is not recognized when plugged into the computer. I’m guessing its possible the logic board is fried or maybe just the battery? Should I try replacing the battery next? Any advise would be great thanks. :)

Hello Scott, I would recommend bringing it to a Apple Store and see what they say. I would say trying to replace the battery is not a bad Idea. I would purchase a battery and try it. Even if it does not work you will have the extra battery just in case you need to repair another phone in the future. I wish you the best of luck with your predicament. Have a great one, Keegan Bourque
