I dropped my iPhone in tapwater.

Hi

Ok so the best thing we can do at the moment is work fast as the quicker we do this the higher the chance of the device surviving is

1)attempt to turn off the iPhone and use this guide to open the device and disconnect the battery

Substituição da bateria do iPhone 6s

2) once the battery has been disconnected,removing the logicboard is the best thing to do next

Here’s a guide for that

iPhone 6s Logic Board Replacement

3)next ether take the parts to a reputable phone repair shop (that specialises in water damage )or take the stickers(and shields off it you have a hot air rework station along side the skills)then dowse the board is isopropyl alcohol and clean away any corrosion(white,blue or green stuff)

Also keep a eye out for any burnt components,it could also be worth putting it for a ultrasonic bath

After doing the above leave it to dry and DON’T put it in rice,rice doesn’t do anything and can sometimes make it worse by adding debris from the rice into the mix

If the phone doesn’t work after that a repair shop it probably your best bet

Hopefully this helps

Any questions please ask

Thanks:-)
