Newer iPhones can sense when their Lightning port gets wet

None of Apple's iOS devices are waterproof, which has become more obvious as competitors such as Sony and Samsung launch fully waterproof phones. 

But a new iOS feature, spotted in the beta 3 version of iOS 10, somewhat alleviates the issue by warning users when an iPhone's lightning port gets wet. 

Spotted by EverythingApplePro, the feature appears to only work with the iPhone 6S, iPhone 6S Plus and iPhone SE, even though it could theoretically work with newer iPads and iPods, which sport a Lightning port as well. 

If you get water in the Lightning port, your iPhone will display the following message: 

Disconnect Lightning Accessory

Liquid has been detected in the Lightning connector.

To protect your iPhone, disconnected this Lightning accessory and allow the connector to dry.  

In many cases, when you see this message it will already be too late. But if it saves even a small percentage of iPhones about to die a watery death, it'll be worth something.

This new feature tells us very little about the possibility of a future waterproof iPhone. But the fact that Apple has included a moisture sensor of some sort in its newer iPhones, and hasn't done anything visible with it until iOS 10, is definitely intriguing.
