My sister dropped her iPhone 5s in the water for about 2~5 seconds and immediately took it off. I don’t know if she turned the phone off (or if it was still working) and I can’t ask her right now because se is travelling. I opened it and tested the battery in the multimeter and it read out 3v so i assumed that the battery is ok. I also claned it the whole board with a kind of alcohol (the seller said it is made to clean PCB) and a tooth brush. I then let it dry for an hour and tried to turn it on but nothing happened. Before cleaning it had a little bit of some weird blueish thing next to the screen sockets. I also connected a lipo battery I have directly to the + and - poles and a spark came off (I thought it could be short circuit). Checked any heat trying to power on the board but absolutely no heat. Anyone has any ideia of what I can do or what it could be? Plugging in the USB doesn’t do anything in my computer
water damage requires the heat shields on the logic board to be removed and the device placed in an ultrasonic cleaner. After that a new battery regardless of reading should be used along with a new screen and charging port. A careful inspection for corrosion should be made prior to any power up. Check for shorts - also if this is to just repair the phone it may not be worth it, if this is for data recovery there are a couple of reputable places.
