Depending on the extent of the water damage, a mobile phone left in a bag filled with uncooked rice for several days may be saved. For the purpose of drying out electronics, unenriched rice is the preferred choice as it does not leave as much dust on the device.
When attempting to save a phone that has been exposed to water or other liquids, it is best to leave the device turned off until it has fully dried to avoid additional damage to components. After several days in a bag of rice, leaving the phone in a slightly warm place for another day or two ensures that it is fully dry.
