My phone got some splash water. Unfortunately some water drops landed in the usb charging port. The phone gave me the error message that it detected moisture and i should dry it.
At some point the phone died because of low battery. I did not have charged it yet because of the concernings that the water and charging could damage the phone.
UPDATE: i used paper towels and let it dry overnight. I charged and there was no warnings.
If it’s only the port on a phone that’s at least resistant to water ingress, then it should only be a few hours regardless of what method is used. As long as excess water is shaken out, tiny droplets will evaporate in only a few minutes unless the environment is very humid.
If it’s not at least resistant to water, it could take much longer, or already be messed up.
