Water damaged phone keeps turning itself on

Last night, I set my phone down in the cupholder of my car...forgetting there was already a cup with water in it. I took about three minutes for me to realize what I had done. I shook out the water and took off the case and (unfortunately) turned the phone off and then back on. When I got back home, I turned it off completely and put it in a bad of rice. Now, 12ish hours later, my phone keeps turning itself back on. When I touch the home button, it immediately goes to the "slide to power down" screen. Do you think this is a motherboard thing? I have a feeling it might be fried.

Hi,

As you know water and electronics and electricity are not a good mix.

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.

Rice is good to eat but it does nothing to fix the problems caused by corrosion.

Don't Put Your Device in Rice. Here's Why...

First do not turn on your phone and then you need to remove the battery as soon as possible from the phone to minimize further damage.''

Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 90%+ to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% and is not as effective. If you do check the label to verify the amount

Here is a link that in general, describes the process.

Electronics Water Damage

You will probably have to replace the battery as it is very hard to recover a battery from 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.

If this process seems too daunting, take your phone to a reputable, professional phone repair service and ask for a quote for a repair. If you decide to do this, do it sooner than later.
