My son's iphone took a dip in a swimming pool. I almost got it working. I had to take it apart and clean the boards with alcohol because there was some corrosion from the chlorinated water. Everything works fine now except the battery. It has a good charge on it, but the iphone sees it as being less than 10%. I have run the phone off a 3.7v power source and it is working. I just need to fine a replacement battery and the small circuit board that sits right on top of the battery.
