Smartphone Care: Risks of Using Rice to Dry Water-Damaged Devices

Using rice to dry a water-damaged smartphone is a common but potentially harmful practice. While rice can absorb some moisture, it is ineffective at removing water from internal components and can introduce fine particles or dust into charging ports and other openings.

Experts and official guidelines, including those from Apple, warn against using rice or heat sources like hair dryers or radiators, as high temperatures can damage batteries, displays, and device seals. Compressed air may also cause additional harm.

To mitigate damage, users should immediately remove the device from water, power it off, and remove any protective cases. The device should be dried with a soft, dry cloth, and the charging port should be pointed downward to allow liquid to drain. Finally, the phone should be left to air dry in a well-ventilated area at room temperature.
