While the upcoming iPhone 7 is rumoured to be waterproof, Apple looks set to ensure that older devices offer users more peace of mind too.
Those trying out iOS 10 beta 2 have found that a warning prompt will appear if water gets into the Lightning port at the bottom of a device. As the photo below from EverythingApplePro shows, users are told to remove the cable to prevent any major damage being done to their phone. It says, "To protect your iPhone, disconnect the Lightning accessory and allow the connector to dry."
Users of the iPhone 6S, iPhone 6S Plus and iPhone SE have found this to be the case, but it may apply to older handsets too.
Apple is yet to confirm that this is a feature of iOS 10 and is yet to comment on the discovery.
