Last weekend, the iPhone 6s and iPhone 6s Plus were submerged under water for an hour which they managed to survive pretty easily. This led many to speculate that the new iPhones are secretly waterproof. The test even got the folks over at iFixit interested and they decided to teardown a few more iPhones to find out the truth.

As it turns out, Apple has increased the size of the lip running around the frame of the new iPhones so as to install a gasket on it. The size of the lip has increased by only 0.3mm, which might not seem like much, but once you consider how limited space is inside an iPhone, this is a big deal. Apple is pretty serious about this gasket and it is even using color co-ordinated gasket strips depending on the color of the display.

Apple has also updated every logic board connector on the new iPhones and surrounded them with a tiny silicon seal. These tiny seals will play a huge role in the survival of your iPhone when it is accidentally exposed to water. Apple had filed a patent for these waterproof silicon cases back in March this year.

Besides the above, there are no other major changes that Apple have made to seemingly make the new iPhones water resistant. Nonetheless, while the new iPhones are not waterproof, the gasket and the silicon seals will go a long way in saving your new iPhone from any accidental water spill.

Early iPhone 7 rumors already point to the device coming with a waterproof design.
