Hi, The impurities in the water creates corrosion and provides circuit paths for the electricity that were not in the operating design of the phone. The corrosion starts immediately and is ongoing until it has been all cleaned away. Also the fall itself may have damaged something when the phone landed in the water First do not try to charge or to turn on the phone and next disconnect the battery as soon as possible so as to minimize any further problems. Then you need to disassemble 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 water and corrosion. Do not use “rubbing alcohol” as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it, check the label to verify the amount of IPA. The higher the concentration (%) of IPA the better Here is a link that describes the process. Electronics Water Damage As always with electronics, especially surface mounted pcb, be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Any shields that may be covering components may need to be removed as the water may have got in under them and there is corrosion occurring there as well. Also the ends of any cables and the connectors need to be cleaned as well. Hopefully after you have done all this the phone might possibly work correctly again. Here is a teardown video for the phone, that may help. If this process seems too daunting, take your phone to a reputable, professional mobile phone repair service, experienced in liquid damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later. It isn’t going to fix itself.
