Yes, even when you do not see any sign of corrosion, it still can be water damaged. I had a guy bring in a iPhone 6 he dropped in water and wasn't even in it for 10 seconds. It still worked, but slowly. He also did everything it says to treat water damage with. Few days later the device finally did not charge and did not power on. The motherboard shorted (even where you can't see). You should take it into apple and let them run a free diagnosis and if the motherboard is indeed bad, it will pop up on their end!
