I dropped my cracked i phone7 in water just for a second. Had a hole at the top! I dried it off and it worked for a few minutes then died. Will not come on and has been on the charger. Do I just need to replace the screen? Or could the water have ruined the whole phone?!
Hi, The waterproof integrity of the phone has been negated by having a hole in the case. As you know water and electronics and electricity are not a good mix. The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone’s operating design and could damage the components. First do not turn on your phone and then you need remove the battery as soon as possible from the phone to minimize any further damage. Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores)to remove all traces of corrosion and water. Do not use “rubbing alcohol” as in some cases this is only 70% IPA or less, can contain scents and is not as effective. If you do check the label to verify the amount of IPA. The higher the % the better Here is a link that describes the process. Electronics Water Damage As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Hopefully after you have done all this the phone might possibly work correctly again.
