Apple isn't one to keep new iPhone features secret, but a video uploaded to YouTube suggests that there's one iPhone 6s feature that didn't make its way onto the spec sheet - water resistance.
The video shows both an iPhone 6s and iPhone 6s Plus both surviving over an hour under water.
Here, take a look for yourself.
While I probably wouldn't give my new iPhone a bath based on this evidence, it should be reassurance for those who take their handset outdoors (or those who are careless around the shower, bath, or toilet!).
