To prevent further damage, immediately remove the battery from the phone using a small set of pliers or your fingers. Water damages the circuit board, a key part to battery function, and getting the battery out of the wet location lessens the likelihood of circuit board damage.nce this happens, remove the battery. Wait a few minutes, and then replace the SIM card and the battery, keeping the phone off. Recharge the phone to a complete charge while in the off position. Turn on the phone once it is completely charged.
