Liquid exposure constitutes a critical threat to an iPhone’s internal electronics. The actions taken within the first hour following submersion will directly determine the probability of a successful recovery. Failure to follow correct procedure can lead to irreversible logic board failure.
This guide provides the essential, time-sensitive steps required to mitigate immediate damage. It also outlines the limitations of at-home remedies and clarifies the necessity for professional intervention to address long-term, hidden damage caused by corrosion.
Critical Emergency Procedure: Actions Required Within 60 Seconds
Execute these steps without deviation. The objective is to immediately halt the electrochemical reactions that destroy micro-circuitry.
- Remove From Liquid Immediately The duration of submersion directly correlates to the extent of internal liquid ingress. Remove the device from the source of moisture instantly.
- Power Down the Device If the device is on, power it off via standard procedure. If the screen is unresponsive, perform a hard shutdown. Do not under any circumstances attempt to power it back on. An active electrical current passing through wet components will cause catastrophic short circuits on the logic board. If the device is already off, do not alter its state.
- Do Not Connect to Any Power Source Introducing a charging current to a wet iPhone is the most common cause of irreparable damage. Any attempt to charge the device will accelerate corrosion and short-circuiting.
- Eject the SIM Tray Removing the SIM tray provides a necessary ventilation point and depressurizes the internal chassis slightly, aiding in passive moisture evaporation.
Debunking a Common Myth: The Ineffectiveness of Rice
The colloquial advice to place a wet device in uncooked rice is technically flawed and counterproductive.
- Insufficient Desiccation: Rice lacks the hygroscopic properties required to absorb water vapor effectively from within a sealed device chassis. Its effect on internal humidity is negligible.
- Contaminant Introduction: Rice introduces starch, dust, and particulate matter into the device’s ports (Lightning, speaker grilles). When mixed with residual moisture, this creates an abrasive and conductive paste, exacerbating the problem.
This method provides a false sense of security while allowing internal corrosion to progress unchecked. Avoid it completely.
Correct At-Home Drying Protocol
This protocol is for external and atmospheric drying only. It does not address internal moisture trapped under components.
Step 1: External Moisture Removal Wipe the exterior of the iPhone with a dry, lint-free microfiber cloth. With the charging port facing downward, tap the device firmly against the palm of your hand to expel any water trapped within the port and speaker channels.
Step 2: Promote Evaporation Place the device on a flat, dry surface in an area with good airflow. Positioning the device in front of a fan (using cool air only) will accelerate the rate of surface evaporation. Do not apply heat. Heat will warp components and can cause moisture to vaporize and spread further inside the chassis.
Step 3: Use Commercial Desiccants For superior moisture absorption, place the device in an airtight container with several silica gel packets. These are engineered specifically for this purpose and are vastly more effective than rice.
Step 4: Allow for Extended Air Drying Do not attempt to power on the device for a minimum of 48-72 hours. This period allows for the slow, passive evaporation of moisture from shallow internal areas. Any attempt to activate the device sooner risks a full electrical failure.
Limitations of DIY and The Necessity of Professional Intervention
After 72 hours, the at-home remedy potential has been exhausted. If the device fails to power on or exhibits functional abnormalities (screen discoloration, faulty charging, muffled audio), it is confirmation of internal component damage.
The primary threat is not the water itself, but the mineral deposits and corrosive residue it leaves behind after evaporating. This corrosion actively degrades solder joints and conductive pathways on the logic board.
Professional water damage remediation is a technical cleaning process, not a drying process. It involves:
- Complete Disassembly: The logic board must be removed from the chassis for treatment.
- Ultrasonic Cleaning: The board is submerged in a specialized isopropyl alcohol solution and subjected to ultrasonic frequencies. This process safely removes all corrosive buildup from under and around micro-components, something no amount of simple drying can achieve.
- Microscopic Inspection and Repair: After cleaning, a technician examines the board under a microscope to identify and repair any remaining damage to circuits or components.
This is the only industry-standard method to reliably reverse the effects of liquid damage and ensure long-term functionality.

Frequently Asked Questions (FAQ)
Q: What is the probability of a successful repair for a water-damaged iPhone? A: The probability is directly correlated with the speed of the initial response (powering down the device) and the type of liquid. Immediate professional intervention offers the highest chance of a full data and device recovery.
Q: Can data be recovered from a water-damaged iPhone that will not power on? A: Yes, in many cases. The primary objective of professional repair is to restore functionality to the logic board, where the NAND memory chip (containing all user data) resides. Data recovery is often successful even if other components like the screen require replacement.
Q: Is saltwater exposure more damaging? A: Yes. The high conductivity and corrosiveness of salt water dramatically accelerate component failure. If the device was exposed to salt water, immediate professional cleaning is not recommended—it is critical.
