I water damaged my phone about a year ago and it would not turn on. I then went and got it fixed at a shop (they used that cleaner stuff) and the phone seemed to work. After a few months my phone wouldn’t turn on again. So I got the battery replaced and it worked again. It then, after just a month this time, wouldn’t turn on again. The repair shop said the motherboard (I believe they mean the logic board) is probably damaged from the previous water damage and causing the battery’s to break. Does anyone agree with this? and how would the best way of repairing my iphone? I am keen to fix it myself for recreational purposes.

I actually have a phone with a very similar problem now. The iPhone I have has a new battery but it drains so quickly. After doing some research it may have something to do with the U2 IC. Unfortunately it isn’t an easy repair so you will probably have to have a professional do it.

water damage repair is a hard fix, most techs will only repair phone and hope it stays on long enough to get data off. If phone happens to continue working after if has been ultrasonic cleaned and components replaced that were damaged then the device is good to go. If the contaminants in the water are not addressed properly they will creep up and damage other components, constant heat from the phone being turned on and whatever was left behind will continue to grow and damage phone. make sure to remove shield to clean all components on motherboard.
