Chosen Solution
So, my daughter didn’t realize her iphone 6s was in her jeans pocket until about 10mins into the wash cycle…. great :-/ After that, the phone was dead and got very hot. It took me about an hour to find a screwdriver small enough to open the phone. I eventually got it open (without further damage) and used a paper towel to blot any visible moisture. The battery had cooled down too. I simply put it in a ziploc bag with rice. I ordered a replacement battery and the charging port/headphone jack assembly. When I got the tools, I started the replacement process. There was no longer any moisture in the phone. I followed the directions and replaced the battery and the charging port assembly. I tried to turn on the phone and nothing happened. No screen, no vibration, nothing. Except, I did notice that the on/off side button was starting to get a bit warm. So I unplugged the battery. Any ideas as to what else may be wrong?
Ouch, sorry for your trouble. You mentioned that the phone was only placed in rice and you dabbed it to remove some moisture, however you need to clean up the unit and hopefully get it running again. I tried to find the lovely details of this work by @oldturkey03 , however I couldn’t find it. Here is one from @refectio iPhone 6s water damage Good Luck Friend Repairing iPhone Liquid Damage
@eprosch two things are going against you. First the rice, always skip the rice. It will not prevent corrosion nor will it fix the phone, it is a misleading myth. It is the equivalent of not doing anything. Second the waiting for a few days. Bad idea since corrosion will start immediately. It would have been safer staying in the water. STOP continuing to try to charge, sync or otherwise use your phone. This potentially can make a bad situation worse. The very first step I would take is to disassemble your phone. Use this teardown to help you disassemble your phone. Take a careful and close look at all components and connectors. Truly assess the damage. Look for major corrosion, evaluate the pins in the connectors etc,. Take a look at all connectors as well as cable ends. You absolutely must remove all the EMI shields. If you do not remove the shields, you are not cleaning the board. Once you got the gross contamination cleaned, use 90%+ isopropyl alcohol and clean your parts some more. For a proper cleaning, use this guide. It was written for a Apple iPhone 3G but it is still pertinent to your phone as well. I can not stress the importance of a good cleaning enough, so do it over and over while replacing the alcohol after each cleaning. Do not use compressed air for the cleaning since that can drive liquid as well as corrosion particles into areas that will cause trouble later on. Do not use drinking water, if you need to use water, use sterile water. Also, you do not need to leave it to dry for a day. Isopropyl alcohol in the higher concentration will evaporate quickly and dissipate the water. The importance here is the cleaning. It would of course be best to get it professionally cleaned Do not forget to replace the battery. This is a must and not an option. It will fail if you do not take care of it now. After that reassemble your phone and re-evaluate. For as long as you have not cleaned your board and replaced the battery, everything is just a guess. Keep in mind that water damage is the hardest to troubleshoot and to repair.
