How waterproof is your smartphone?

Water- and dust-proofing have become a major feature in leading smartphones in the last few years, with the Sony Xperia Z range leading the charge towards making your phone that little bit more life proof. Now as the Samsung Galaxy S5 also appears with dust and water proofing, it seems like worrying about your handset might be a thing of the past.

But that's not entirely true. For one thing, each device is rated with a different IP code - a two digit number which refers to the level of protection from dust and water. So the S5 is rated at IP67 which means it's impervious to dust and can be immersed in 1 metre of water for up to 30 minutes.

But there are a number of caveats - like making sure the ports are all tightly closed. It's also important to note that this rating only applies to being placed in static water, a powerful spray onto the phone is not covered.

Far more important is a factor that's often overlooked - most waterproof smartphones are not immune to seawater!

That's right - the salty substance that covers 70% of the surface of the Earth is a no-go area for your phone. That's because even with the flaps sealed and taking great care salt is a master at getting into places it shouldn't be. And when it does, it's practically guaranteed to muck up your electronics and short out the phone, possibly for good.

As holiday season continues, it's definitely worth remembering that even if you've got the latest handset with the most impressive specs and protection, there's a very good chance that it won't survive a dunk in the sea. And you should also know that most warranties won't cover water damage on smartphones.

So what should you do if it does get soaked? Turn the phone off immediately and wash it with fresh water as soon as possible. Leave it to dry and hope for the best.

Of course it better to ensure this doesn't happen in the first place so you can invest in a fully waterproof case for the phone which guarantees protection. You can even get a simple bag-like case that helps the phone to float in case you drop it and still gives you access to the screen.

Or we might even suggest leaving your phone somewhere secure like your hotel safe and just enjoying your holiday without having to worry about IP ratings or the insidious power of salt!
