Contact with liquid in the charging port can trigger alerts, block charging, and leave the user unsure of how to act. Manufacturers advise avoiding homemade solutions, heat, and objects in the connector, prioritizing natural ventilation, waiting, and care with wet cables.
Putting a wet phone in rice is not the safest recommendation when there is liquid in the charging port, despite the practice being repeated for years as a homemade solution to try to recover devices after water accidents.
Apple advises against this method because small particles of rice can reach the iPhone and cause damage to the device, especially when they come into contact with sensitive areas near the Lightning or USB-C connector.
The central recommendation is to stop charging, disconnect cables, and wait for the device to dry before plugging it back into power, as the hasty attempt to recharge can increase the risk of connection failures.

In compatible iPhones, the system may display a liquid warning in the Lightning or USB-C connector and temporarily block charging, a feature created to protect the phone, cable, and connected accessories.
Such accidents usually happen in simple situations, like rain, falling into the sink, beverage splashes, or moisture inside the backpack, but the reaction in the first few minutes can directly affect charging safety.
When the iPhone detects liquid in the connector, cable, or a connected accessory, charging becomes unavailable until the connector, cable ends, and accessory are dry.
Even with the screen and casing apparently dry, the USB-C or Lightning port can still retain moisture in small areas, especially in the internal contacts and the ends of the cable exposed to the same accident.
Why rice is not recommended
Apple advises that the iPhone should not be placed in a bag of rice, as the practice can allow small particles to enter the device and create an additional risk instead of ensuring safe drying.
Also not recommended is the use of external heat, compressed air, or objects inserted into the connector, as hairdryers, heaters, paper towels, cotton swabs, and sharp items can affect delicate components.
To remove excess liquid, the guidance is to gently tap the iPhone against your hand, with the connector facing down, and leave the device in a dry, well-ventilated area without exposure to intense heat.
After at least 30 minutes, the user can try to charge again or connect an accessory, but the return of the alert indicates that moisture may still be present in the connector or cable ends.
If the message appears again, the guidance remains the same: keep the phone in a dry and ventilated place, as complete drying can take up to 24 hours, depending on the device’s conditions.
Charging a wet phone can cause permanent damage
Insisting on the cable right after contact with liquid is among the riskiest actions, because the passage of energy in a damp port can compromise the connector pins and impair the charging function.
Apple states that charging the iPhone with a wet Lightning or USB-C connector can corrode the connector or cable pins, cause permanent damage, or interrupt the proper functioning of the connection.
The lock displayed on the screen reduces this risk, but it does not mean that the phone is free from any internal damage, as the impact varies according to the amount of liquid, exposure time, and the physical state of the device.
On Galaxy phones, Samsung adopts a similar logic by displaying the water drop icon when it detects moisture in the USB port or nearby areas, temporarily disabling charging.
This mechanism works as protection against water and corrosion damage, which is why the company advises disconnecting the charger immediately, carefully removing excess moisture, and leaving the phone in a ventilated area.
What to do in the first few minutes
The first step, for any device, is to remove the cable and avoid new charging attempts, because connecting the charger while there is still moisture can keep the alert active and hinder the recovery of the port.
If the charger has also been wet, simply changing the phone or insisting on the same accessory does not necessarily solve the problem, since the cable ends also need to be completely dry.
For Galaxy models, Samsung recommends gently shaking the device a few times with the port facing down, placing the phone on a dry cloth, and leaving it in a place with good air circulation.
When the moisture icon persists or the phone continues not to charge, the manufacturer advises seeking support, especially if the issue remains even after the device has gone through a drying period.
Anxiety usually appears when the phone turns off after contact with water, but connecting the charger before complete drying can prevent charging and increase the risk of malfunction in the connector.
Wireless charging can be an alternative only in compatible models and when the exterior is dry, but this option does not eliminate the need for care with a wet USB-C or Lightning port.
Water resistance does not eliminate the need for care
Sensors and alerts help prevent charging in unsafe conditions, but they do not make the device immune to liquids nor recover components affected by water, drinks, dirt, or debris stuck in the USB port.
Liquids like soda, coffee, saltwater, and cleaning products can leave residues more difficult to remove than clean water, which reinforces the need to avoid heat, objects in the connector, and new charging attempts.
The rice myth remains strong because it offers a quick response in a moment of concern, but official guidelines prioritize natural ventilation, careful removal of excess liquid, and interruption of charging.
The safest measure, therefore, is to slow down, disconnect cables, and wait the necessary time for the connector and accessories to dry before any new charging attempt.
