iPhone 6 water damage, battery replaced won’t turn on

Hi guys,

Anyone got any ideas on what I can do.

My boyfriends iPhone 6 got dropped in a pool and was retrieved in about 10 seconds and then was switched off. He had no rice so just left it in the sun for over a week.

About 4 weeks later I got hold of it and opened it up. It’s obvious water got in as all the water sensors had been activated but there wasn’t much corrosion. My dad tested the battery and found it was dead so I bought a new one and put it in. The phone worked straight away and functioned normally. I went to turn it on the next day and it wouldn’t turn on and it looks like it’s not even charging as I’ve left it to charge about an hour.

Any ideas on what I could try? Could it be short circuited? Is there anything I can do?

Many thanks x

A simple visual inspection often won't reveal the true damage that liquid damage causes. Most often the corrosion/oxidation is under the chips and cant be seen without removing them. That process is not only expensive but only possible with professional equipment and expertise. The first step should be to use an ultrasonic cleaner with the proper chemical solution to clean the logic board. I use Branson EC fluid with distilled water heated to 140F. Also worth noting, is that the EMI sheilds should be removed before the treatment. This process uses the solution to "vibrate" the corroded terminals/connections and remove the oxidation under the chips. About 75% of the logic boards I treat become functional following the treatment. Also worth noting is the fact that the "rice" treatment really isn't effective in most cases. It would need to be in physical contact with the liquid to absorb it.

That’s interesting, I’ll look into trying that. Would the phone be one of the 25% that won’t work if it has short circuited? (Just thinking that’s most probably what’s happened as it was turning on and off easily yesterday but won’t do anything today)

Thanks x

No way to tell without doing the treatment. A component may have had a poor connection due to corrosion or oxidation and during use, it just "overloaded" that weak connection and caused the phone to become unresponsive. If you pursue the ultrasonic cleaning, be sure to use the appropriate chemical. As I mentioned earlier, I use Branson EC in my cleaner, then follow that up with a soak in 99.9% alcohol, and finally dry it in an oven @225F for 15 min to remove all traces of residual moisture. Iso alcohol is great for cleaning and is hygroscopic (water absorbing), but won't do anything to remove oxidation or corrosion. Proof of that would be if you were to pour iso over your cars corroded battery terminals, it would merely rinse away loose particles and sterilize it. It doesn't counteract corrosion.

Ahh, that makes sense. I’ll have to see what the UK equivalent is as I’ve heard Branson EC is illegal in the U.K.

Oh, that is true. I didn't notice your location. I think I remember seeing some threads when I searched Branson EC regarding equivalent chemicals available in the UK. Good luck!

I guess the only thing worse than putting a phone in rice is not having rice on hand and letting the whole mess fester...what I call "attempted rice" ;>)...sorry, that's a bit of an inside joke in these parts (right @mayer @oldturkey03 ?).

Normally, when a phone is contaminated with water, it is important to open up the device, disassemble it, clean it in IPA and then let it dry. It's not always sufficient but it's the proper first step. Professional decontamination is the preferred route.

At this point, your best bet is to have the phone looked at by a professional shop that does water damage and micro-soldering as you clearly have logic board issues. Not every water damaged phone can be fixed but if the data is important, the data may be recoverable.

@refectio , the phone basically has nothing on it and when I had it on yesterday I took off anything important. Just feels a bit of a waste to throw it in the bin.

Do you know how I could test if it is short circuited? Or in the end would it be the case of basically rebuilding the whole Phone do you think?

If you have any DIY ideas to test or fix that would be amazing. I’m thinking of just replacing all the boards (I like doing little electronics projects)

My dad was an RF engineer and I’m expected to fix all my tech and I’m trying to avoid the whole disappointment stuff there, haha

Thanks x

I recommended smashing in a sheetrock wall, digging out the gypsum and putting the phone in that. Then for a garnish sprinkle with rice , put it in a 550 degree oven for 3 hours After you get out of the concoction you will never have to worry about that iPhone again. Put in the microwave on medium setting for 20 minutes to help charge the battery.

@mayer that is an interesting way of recycling, haha
