I dont know if anyone has asked this, but what happens after 30 mins of the Xperia Z being submerged in water? Though the flaps loosen up and give in? Any ideas?

It will spontaneously burst into flames, even under water.

On a serious note, probably nothing. IP57 is a test made for 30 minutes but chances are it'll survive a lot more. The next level requires endless submersion at a higher depth and that is probably unreasonable to test/expect. I wouldn't try it out though.

You should see the waterproofing as an extra security. Dropped your phone in a puddle, spilled some water over it, need to take a call and it's raining? No problem. It's meant to survive those things. What it is not meant to do is to remain operational while submersed in water (they've said this on their website). It will, but it's not made to be used as an underwater camera or as a shower texting device (even though it can do those things).

Re: After 30 Minutes?
Haha

Great to know, thanks.

I would though like to see a review site test it for longer, just to push the Xperia Z to its limits.
Id expect it it text in the shower like the Nokia 5210? Which I used to have years ago.
But I understand the rest. Thanks Ambroos

Edit:

(IP)(5)(7)

IP = Ingress Protection

5 = Dust protected
Desc - Ingress 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

7 = Immersion up to 1 m
Desc:
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 1 m of submersion).

Test Routine:
Test duration: 30 minutes
Immersion at depth of at least 1 m measured at bottom of device, and at least 15 cm measured at top of device


The reason why it's not 8 because for you to be able to get IP58 is


8 = Immersion beyond 1 m
Desc: The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects.

Test Routine:
Test duration: continuous immersion in water
Depth specified by manufacturer

and to get the IP67

6 = Dust tight

Desc: No ingress of dust; complete protection against contact


The highest level is IP68 which requires a dust tight and is capable of staying underwater for an unlimited time. Like submarines.

But this isn't dust tight because of the open ports. And also this can't emerge underwater for an unlimited time because the body isn't airtight and moisture can develop inside the case if submerged longer.



So.......... It is only stated to last 30minutes underwater because that's the criteria level of IP rules is not very specific enough.

So sony only have 2 choices for this... Either go with the rule to state the device that it can be submerged 1meter for 30 minutes or state that it can be submerged down below the water for centuries

So to summarize it all the 30minutes 1 meter is not the device limitation but just the certification's description.

while reading this thread, the follwing question comes into my mind: what about using the phone while taking a bath? don't get me wrong: i do not talk about reading websites UNDER water, but what about the steam? can the phone resist the steam? is this also included in ip 57?

thanks for your answer.

so just to be sure and safe: while taking a hot, steamy bath, i can surf the internet (above the water, of course), and the steam can't do any harm to the XZ?

that'll be awesome. how often did i wish i could use my tablet or smartphone for reading stuff while lying in the bath-tube...

Hot temperature expands air so it should be safe what you need to worry about is cold water Not that water will get inside but the air inside the device could become moisture if it's cold and wet so dunno for sure

from my experience as a diver, I can say that it is not so much about the duration in water but about the depth and the pressure. The deeper you go into water, the higher is the pressure. For every 10 meter, the pressure doubles. From 1 bar to 2 bar and so on. What this means, is, if you go beyond the depth for which the phone is specified and tested, the protective covers might be too weak to hold steady against the pressure of the water around it. Then they'll give in and bulge inside, thus water comes in -> phone's dead!

This may not mean that if you go 1,1m that the phone will die immediately. It could withstand 2 m, maybe even 3 or 5. But I wouldn't bet or try it out. It may survive these depths, but only for a very short time.


To conclude, I would assume that going to swim for 1 hour in up to 1 m should be fine. But going down to 3m for 5 minutes - not so good idea.
