The next iPhone might be able to swim, according to leaks – but it might be kept secret.

The company is working on making its newest iPhone waterproof, according to numerous leaks. The latest suggestion is a patent granted this week for a technique that lets Apple’s mobile devices take pictures properly underwater – apparently suggesting that it is working on letting those devices go underwater safely in the first place.

The company has been gradually working to make its handsets more resilient. That hasn’t just included waterproofing but also making them more able to stand shattering – the newer phone’s use different glass that makes them far less likely to break when they fall out of a pocket or down the toilet.

Doing so helps make people more happy with their phones. It also presumably allows Apple to keep repair costs down, since many of the people who break their phone through contact with water end up taking it to the Apple Store.

But it isn’t clear that if Apple does make the new phone waterproof, it’ll actually market it that way.

The iPhone 6s, for instance, appears to be able to stand being thrown in water – videos on the internet show it being put into bowls of liquid and surviving. But the company hasn’t talked about waterproofing at all, and actually dropping it into any liquid is still not recommended.
