Water damage can be a tricky one and the success rate depends on your ability to spot micro corrosions and how well you clean the board. Also other components may need to be replaced like the battery and charger port. Once you disassemble the the phone you should drop the board in an ultrasonic cleaner with the proper amount of alcohol. one thesis done, blow it dry and reassemble. You should use a new battery and charger port when reassembling, it best practice. Once assembled try top reform a hard reset, given you get a apple logo to show up. Try this treatment twice. If you do have to do it again, throw the board under a microscope and make sure there are no fractures or burnt resistors on the board. Good Luck!

The iPhone need some power which isn't provided by the cable, to turn on. With the water damage, the battery isn't working properly, so you need to replace it, and your phone will work fine.
