I got water in my iPhone and now the charger will not work. Is the phone completely ruined or can I repair

Have Apple evaluate the situation:

For the 'iPhone Service Answer Center' click here --> https://support.apple.com/iPhone/repair/service

For instructions on how to 'Get your iPhone, iPad, or iPod touch ready for service' click here --> https://support.apple.com/HT201557

- "To protect your information and save time, follow these steps before you get service for your device."

If you see a liquid-detection alert on your iPhone, click here --> https://support.apple.com/HT210424

Liquid damage to iPhone or iPod isn't covered by warranty - http://support.apple.com/HT204104 - iPhone and most iPod devices are equipped with Liquid Contact Indicators (LCIs) that you can see from the outside.
