Watch Mobile Geeks immerse themselves in the world of water and dust resistance, pitting the Samsung Galaxy S5 against the Sony Xperia Z2 in a range of grueling tests that including a fish tank, a glass of Belgian beer and visit to a laundrette. Which smartphone will survive? Indeed will any of them survive? You going to have to watch the video to find out!
One of the most important features that was announced at the Samsung galaxy S5 launch a few months ago was the news that the new flagship 5 inch smartphone would be water and dust resistant, boasting IP67 certification. This was a new feature for Samsung and one that seemed squarely aimed at besting Sony, whose have been implementing this water-proofing on their Xperia line since the launch of the Xperia Z year ago.
The Xperia Z2 followed previous Sony Xperia models with IP58 certification, a code that indicates that the device has been tested to comply with certain standards of protection, in this case protection from dust and water. Although not entirely dust or water-proof, IP58 means that the Xperia Z2 is resistant to a specific and tested level; protection from water submersion at a depth of one meter for 30 minutes.
IP codes are classifications of protection from intrusion that you can expect from any given device. Specific codes relate to general intrusion (i.e. from hands and fingers), as well as from dust and from water. These codes are implemented and published by the International Electrotechnical Commission (IEC). IP22 for example is a minimal basic requirement for indoor electrical appliances that indicates little more than the fact the electrical components are not completely exposed.
The Samsung Galaxy S5 is IP67 certified which indicates the same level of water immersion protection (referred to by the second digit) but with more stringent dust resistance indicated by the initial 6, which essentially means dust tight. Whether or not the Samsung Galaxy S5 is indeed more dust proof than the Xperia Z2, we have yet to ascertain and confirm, but I would not be surprised if there appears to be a degree of marketing involved. In the video below Sascha and Nicole focus on the water-proofing of both devices, which would seem a larger threat than good old dust.
In reality, what does water proofing mean to most users, and is it a real make or break feature? Having spoken to several Xperia users in the past, it seems to be a genuinely reassuring feature. The idea is that your phone is going to withstand the rigors of everyday life is important; this includes sudden heavy rain showers (believe me in Taipei we have lots of those), a drop in a puddle, an accidental plunge into a toilet or even being washed at the laundrette by accident. We believe water and dust- proofing is the way forward and something that we hope to see it implemented on more devices. If only they could figure a way of doing it without the flaps and covers….
