Water-proof or water-resistant? Can your new Galaxy S5 or Xperia Z2 truly swim, or is secretly afraid of the water?

Yesterday, Archos CEO Loic Poirier gave us an entertaining, but unfortunate example of how imprecise information can deceive smartphone owners. You, too, might be boasting left and right that your phone is "dust-resistant" and "water-proof". But, are you aware of how much protection your phone really has? If you are, good for you. Otherwise, you are in danger of being misled by the liberal use that both smartphone ads and journalists make of such classifications.

Marketing 101


Water-proof or water-resistant? Can your new Galaxy S5 or Xperia Z2 truly swim, or is secretly afraid of the water?
See, what ads usually do is simply state that the phone is dust and water-resistant or -proof. They also specify which IP-rating the device complies to - often in small print, and in a place you won't be necessarily looking at. We presume this information is included out of courtesy to legal obligations, otherwise smartphone ads practically assume that consumers can instantly decode what "IP57" stands for.

Of course, user manuals usually specify the exact usage scenarios and conditions you should avoid if you want to keep your phone alive. Alas, this is done only after you purchased a “waterproof” phone that actually might be afraid of the water. And besides, user manuals are anecdotal for going over people's heads for some reason.

Yet, with more and more of today's flagship smartphones gaining attention for their toughness, we fear this misinformation could result in many “drowned" devices. If Archos' CEO himself couldn't figure out how much he can push his company's IP54-certified phone, what chance does the average user have?

Obviously, we can't make marketing people change the way they present information. Their task is to sell, not educate. Also, we are not an authority that can "coin" the difference between "water-proof" and "water-resistant", because that's something the International Electrotechnical Comission, which published the IP standard, should do. For some reason, it still hasn't, and that's growing into a problem. 

The problem


Water-proof or water-resistant? Can your new Galaxy S5 or Xperia Z2 truly swim, or is secretly afraid of the water?
See, although the IP standard provides a clear system for rating the toughness of electronics, it is essentially left open to interpretation. For example, let's say a marketer is writing copy for a phone that's IP54-compliant. This translates to "ingress of dust is not entirely prevented, but it doesn't interfere with the operation" and "water splashing against the enclosure shall have no harmful effect". Although the IP54 certification isn't entirely immune to dust, and is completely helpless against immersion in water, its presence and the lack of regulation lets the marketer boldly call the phone "dust and water-proof". Or “-resistant”. Or "-tight". Whatever!

Likewise, here's a real-life example: last year's Sony Xperia Z, which is rated IP57, is known as "waterproof". But, according to the IP standard guidelines, the “7” in “57” means the Xperia Z is good to survive 30 minutes immersed in up to 1m of water. Anything beyond this doesn't guarantee an outcome in which you won't be better off feeding your dead phone to the fishes.

The solution


Water-proof or water-resistant? Can your new Galaxy S5 or Xperia Z2 truly swim, or is secretly afraid of the water?
To help you be absolutely sure that your new extra-tough smartphone is really up for the challenge, we'll introduce you to how the IPxx code works. Don't worry, it's actually very simple:

  • IP stands for Ingress Protection
  • The first digit indicates the level of dust protection
  • The second digit indicates the level of water protection
  • If there's an "x" in place of the left digit, this means no dust protection, only water protection
  • If there's an "x" in place of the right digit, this means no water protection, only dust protection

Use this scheme with the information from the tables below, and you will know exactly how much your phone is protected. For example, you can figure out that the new Samsung Galaxy S5, which is rated IP67, is "dust-tight" and good for "immersion of up to 1m". Likewise, the Sony Xperia Z2 is rated IP58, which stands for "dust-protected" and "immersion beyond 1m" with no time limits. Turns out this one's a tough swimmer!

Dust protection levels


LevelObject size protection againstEffective against
0No protection against contact and ingress of objects
1>50 mmAny large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part
2>12.5 mmFingers or similar objects
3>2.5 mmTools, thick wires, etc
4>1 mmMost wires, screws, etc.
5Dust protectedIngress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact (dust proof)
6Dust tightNo ingress of dust; complete protection against contact (dust tight)

Moto G isn't waterproof, but you still can consider it as water-resistant...sort of.

Sony might be needing more and stronger adhesives if they want to achieve 9K.

9K on a phone? That would be overkilled XD. At that point, you should just find a life proof box and put the phone in.

that would be impractical
i think making the device unbreakable is better, shockproof, scratchproof..

sony is the only company professionel in term of waterproof and dustproof , and i except this year many people will cry about there s5 because a lot of them don't know the difference between waterproof and water resistance .. so take your s5 and my z1 in pool and make the fun begin :D :)

Well I think IP57 is also very good... I have used my Acro S in a pool many times... and also going a little beyond the 1 meter depth test...
I have used it in the sea, and for over 30 minutes at a time....

What you really need to keep in mind is to wash salt water off with tap water... and every now and then I apply rubber vaseline to the flaps to keep them from drying out and crack...

It has been over a year with my phone and it still takes showers and dunks in a pool very nicely.

Last i heard the Galaxy S5 is IP67-certified. The 6 means it's dust proof, while the 7 means it can be immersed in water (up to 1 meter) for 30 minutes. That said, Sony's design is way better.

My first Xperia Z died when I submerged it into water. I did NOT exceed the IP57 limits. Sony didn't give a f*ck, but I was lucky enough to get my faulty Z replaced by my retailer. My second Z still works, after being submerged a hundred times.

What sort of rating should a phone have in order for it to work after spending an hour or two inside a v@gina?

We all know the Z1 have the best design and water proof capablities in a phone than the GSV with it's failure design.

From most water tests, most phones are pretty much IPx4 ...

No one is capable to make beautiful premium phones and simultaneously making it water and dust resistant like sony. The Z series is a True marvel of engineering prowess.

+1 to you sir. I agree with what you said. Also, that amazing Camera

The only reason why i didn't buy Sony i because i really hate onscreen buttons. Also, i love phablets.
So as long as Samsung keeps the buttons off my screen I'll stick to the Note line.

If SS does go to onscreen (which it probably will eventually) I'm going over to Sony.

My only complaint about Sony is indeed the on-screen buttons. It is such a waste of screen space, and the bezel is big enough to fit capacitive buttons. I hope Sony will change it some day, as that will make the perfect phone for me.

Btw i dont think crossing limits of IP (depth of water, duration)wont brick the phone. The moto g, countless nokia phones which without IP rating have survived water dives and what not. And besides the new z2 seems to have aluminium flaps so they are anything but flimsy.

So the GS5 is better at keeping dust out of your phone.
While the Z2 can last longer underwater.

Well I usually find myself getting blasted by high powered jets, so I guess I'll just have to keep waiting for 9k certification
