Check the battery first, connect into charger. If phone was wet, you need to clean it in isopropanol. Or just dry for few days (you can use hair dryer) carefull to dont overheat phone. Even if you think phone is dry it can be still wet. Check if connectors from charger are not dirty. (Check charger, and battery) best way is to borrow battery from friends phone
