iPhone6s plus does Nothing after falling in water

Hello,

This morning I fell in saltwater with my iPhone in my pants. After 30 seconds I managed to get out of the water.

I tried powering it off, but it went off by itself.

1 hour later I opened the iPhone to remove water inside. It was quite wet. I used a hairdryer on low heat with a lot of distance to dry it. So I couldn’t over beat anything.

After that I let it sit outside in the sun for 1,5 hour.

Not seeing any water, I decided to put the phone back together and try turning it on. But it won’t turn on.

I tried replacing the battery but still it wouldn’t turn on.

Please tell me why the iPhone won’t turn on, or what else I can try to fix it.

Update (08/19/2019)

H jayeff,

You really know your stuff, thanks. I disassembled my iPhone, and found that the bottom of the logic board was affected a lot.

I already bought 90% isopropyl to put the logic board in.

I was wondering if I should put the rest of the phone also in the isopropyl, since it is also showing residues of salt and corrosion. Took out the battery already ofcourse.

Also so how long does it need to be in the isopropyl?

Please let me know and I will post the result soon.

Couldn’t get the phone to work. There was visible damage on the logic board. Decided to buy a new phone.

cleaning didn’t help it, but it was fun taking the phone apart and putting it back together again. Much easier than I would have thought

Hi,

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

The impurities in the water (especially sea water) causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion doesn’t stop until it has been cleaned away

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%+ (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 use it, check the label to verify the amountof IPA

Here are a couple of links that describes the process.

Electronics Water Damage

iPhoneの水濡れ・水没ダメージからの復旧方法

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.

Here is a link to the ifixit guide(s) for repairing your phone.

iPhone 6s Repair

If this process seems too daunting, take your phone to a reputable, professional 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.

Hi,

If you want to make certain that all "may" be OK you also have to remove the "shields" which are protecting the CPU etc., as there may be water under them as well.

You won't really know what is wrong with the phone until you are satisfied that you've removed all the corrosion etc and re-assembled it and tried it, as components may have been electrically damaged by the initial contact with water and that the power was still available in the phone. The power button is not a power isolating switch so even if the phone is off there is still power available at certain points on the logic board.

Once you have thoroughly (and carefully) cleaned off any corrosion that is there (or anywhere in the phone) using the IPA and a soft brush and at least visually checked that the components seem alright, allow it to completely dry (shouldn't take too long as it is alcohol which evaporates), check again for any obvious signs of corrosion, then if none, carefully re-assemble the phone and check what happens.

Good luck.
