'''Only responds when being plugged into a charger'''
If you cannot get your Samsung Galaxy S6 to power on but it seems to recognize a charger and the charging light will come on when the phone is plugged in, then this is a good sign as it indicates that there is at least some life left in your phone. If your device falls into this category, then I recommend that you try to locate and then attempt to utilize a replacement battery. The battery may have been damaged by the moisture as opposed to the phone and a replacement battery may be the key in getting your phone to start up and work again. Any battery that you know is operational and is functioning properly should work. You can barrow one from a friend or family member or if your phone is still relatively new you might even want to consider going down to a local retail location to borrow a battery from one of the phones on display at that location. Just temporarily to see if it works of course. If it another battery does work, then you will have successfully located the cause of the problem and you can look into purchasing a replacement battery.
If you determine that your Samsung Galaxy S6 requires a replacement battery or if you are unable to find a working replacement to use as a test, then I suggest that you consider checking online to see what a replacement battery for your particular device is selling for. Typically, replacement batteries are pretty affordable and are relatively easy to acquire from online stores like Amazon.
Note: If your particular model of smartphone was designed with a non-removable battery then this task is going to be a little more difficult for you but will likely require you to take apart your phone in order to remove and then replace the battery. If your phone falls into this category, then you may want to save this step in troubleshooting as the last and final solution for your cell phone.
