APPLE'S NEW iPhone 7 and iPhone 7 Plus are being advertised as "water and dust resistant" but water sports enthusiasts should take note that they are not water and dust proof.
The difference is important if you are a scuba diver who always needs to be connected, because you'll get nowhere with Cook & Co if you send your waterlogged phone back for replacement under warranty.
"Splash, water and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear. Do not attempt to charge a wet iPhone; refer to the user guide for cleaning and drying instructions. Liquid damage not covered under warranty."
Interestingly, the blurb doesn't mention dust damage so speedway riders may be OK.
But what does IP67 mean exactly? Well the '6' is a mark (out of 10 presumably) for dust resistance while the '7' is a measure of resistance to water.
Specifically, a '7' rating means that "ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1m of submersion)".
However, these tests are conducted in controlled laboratory conditions using water rather than other fluids, and Apple will not guarantee that your choice of water sport is compatible with its phone. You may not even be able to drop it down the toilet or take it for a spin in a washing machine.
All sorts of unfortunate things can happen when marketing guff meets legalese. Last year, for example, Sony produced a number of advertising pics with smiley 20-somethings frolicking under the sea and filming on an Xperia Z5 phone (certified IP68, no less).
At the same time, the firm's official advice warned customers not to use the handset underwater. Confusion reigned.
Samsung's Galaxy S7 range is also certified IP68, meaning it has been tested underwater for 30 minutes at depths of up to 1.5m (take that, Apple).
This is at least is one thing that Samsung can hold onto after being forced to recall Galaxy S7 Note phablets owing to risk of explosion. µ
