I fixed two water-damaged iPhone 6S in past two days. My dear customers told me that they have used rice to dry their iPhone immediately after the phone got wet. But unfortunately rice didn’t work as they expected.
Phone one
Customer told me that his phone worked fine after drying with rice for a few days. However, it only worked fine for several days, then he found that the screen didn’t respond to touch. As we know iPhone 6S screen touch function chip is integrated with the screen itself, I guessed the screen had been damaged or the motherboard had some issue caused by water damage.
I disassembled the phone and found some corrosion on screen and the water damage indicator was red.
I took the motherboard out to check water damage. Some corrosion happened near the cameras power IC chip. The cameras of this phone would be malfunctional soon if these corrosion had not been cleaned. After cleaning all suspected spot on the motherboard, I tested it with the old screen and a new screen, unfortunately only new screen can repsond to touch. I hope my customer could have brought it to me immediately after wet I might be able to save the screen for him.
Phone two
This phone experienced almost the same with the former one, got wet and dried by rice. The sisutation of this phone was worse, there’s no sign of life from its screen. I disassembled it and found there still had water insider right on the battery and the back of screen.
The motherboard started to corrode as well.
Finally, this phone is back to life with a new screen and a few parts replaced.
Conclusion
Rice can not dry out all the water or moistuuinside the phone. Sometimes it might work but the residual moisture will damage the screen or motherboard later. A good way to deal with liquid damaged phone is disassemble it first then use 99% alcohol to dry out the motherboard. If you cannot disassemble the phone please bring it to repair technician ASAP. Finally there’s a VERY important reminding for customer, please don’t try to charge your phone to test it work or not after your phone got wet. I had a customer came to me with a water damaged iPhone 6, she just bought it one week ago before it got wet by a glass of water. She brought it to me several days later but I found it’s already too late to fix it. The corrosion happened almost everywhere on the mother board. She plugged her phone to charge to see whether the phone could be alive again.
