A patent filed by Apple suggests a fully waterproof iPhone could be closer than first thought.
The filing is for what Apple snappily dubs a ‘self–healing elastomer’. In layman's terms, that's a rubbery material that Apple plans to secrete inside an iPhone’s ports, such as the Lightning connector at the bottom of the device.
When a cable isn’t inserted it effectively provides a seal, preventing liquid from getting into the device’s key internal components and rendering it unusable.
However, once a user plugs in their cable, the seal 'breaks' to allow for normal charging. Naturally, the seal re-forms once the cable is taken out.
This freshly discovered patent fits in with Apple’s recent, rather clandestine experiments to make iPhones waterproof.
