Regardless of how your phone ends up soaked, whether it is from a downpour, mishandling it near water sources or a bucket accident, the most commonly used remedy is to place the device in a bag of rice. The dry absorbent rice should help suck out the moisture, rescuing your device, so the theory goes. Experts have pointed out that is a bad idea and using a bag of rice to dry your iPhone may expose it to potential damage from rice particles, as such, users need to be cautioned against it.

Researchers have been claiming for years that it's all a myth and rice doesn't actually dry your phone faster and could slow down the process, leaving your logic board susceptible to further damage. Instead, Apple suggests the following steps:

1. Tap your iPhone gently against your hand with the connector facing down to remove excess liquid. Leave your iPhone in a dry area with some airflow

2. After at least 30 minutes, try charging with a Lightning or USB-C cable or connecting an accessory.

3. If you see the alert again, there is still liquid in the connector or under the pins of your cable. Leave your iPhone in a dry area with some airflow for up to a day. You can try again to charge or connect an accessory throughout this period. It might take up to 24 hours to fully dry.

4. If your phone has dried out but still isn't charging, unplug the cable from the adapter and unplug the adapter from the wall ( if possible) and then connect them again.

Furthermore , Apple also urges against drying your phone with an external heat source or compressed air, or inserting a "foreign object," such as a cotton swab or a paper towel, into the Lightning or USB-C port. 

If your phone is unresponsive, power it off immediately and avoid pressing any button. The subsequent actions will vary depending on your situation, but generally: use a towel to dry it and place it in a sealed container along with silica packets if available. Refrain from charging it until you are certain it's completely dry.

Granted, iPhone have been able to withstand submersion in water at a maximum depth of 6 meters, up to 30 minutes. So chances are you haven't had to worry about liquid damage for a while. But if you ever do, just leave the rice in the cabinet.
