Water-Damaged Phone: Save the Data Before the Phone
Most water-damaged phones are killed by the next charge attempt, not by the water. Corrosion and electrochemical migration accelerate the moment current flows.
Immediate actions
Power off, do not charge, do not press buttons repeatedly. Separate the battery if you can, and get the board cleaned professionally — fresh water, salt water and sugary drinks differ in how fast they attack.
Data first when possible
If the phone is still detectable by a computer, take a full logical backup before any repair. The screen, battery and housing are replaceable; the board and its keys are not.
What cannot be saved
If corrosion has eaten through the storage supply or the secure element, an encrypted phone's data is unrecoverable. This is decided by the board, not by effort.
FAQ
Rice or a hairdryer?
Neither. Rice adds dust, hot air moves components and drives moisture deeper.
Can data be extracted if the screen is dead?
Usually yes if the board works and the device can be unlocked with external input.
Is salt water worse?
Much. Chlorides accelerate corrosion and pitting; hours matter.
Boundary: corrosion damage is progressive and irreversible. Speed of cleaning decides more than any recovery technique.
