Like you I am not a scientist and do not know for sure, but once the bucket is filled with water wouldn't the water pressure be the same as that on the bucket itself?

I've noticed a few other people making this argument. One person said that if an iPhone 7 gets water damaged, it doesn't necessarily mean it had been abused, because every phone can't reasonably have identical tolerance.
I would disagree with this. If you have a look at the tolerances the iPhones are built at and the components inside, there isn't a micron of space that hasn't been used up. No doubt in my mind; if your iPhone 7 gets water damaged, it would be user error and nothing else. Absolutely no chance of it happening with use in the rain or anything like that.
Of course you can't claim that they'll all have identical waterproofing. But it's as close as can be. It'll take something out of the ordinary to water damage any iPhone 7.
“But, but… IP68 > IP67”
Apple is conservative as always and sammy overconfident as always.
Kind of weird that the fish were asking Siri stuff.
Salt water is not good for the outside of the phone. Salt is aggressive. Metal will start to rust. So even if the phone was 100% water proof, salt water is bad news. But if water does get in, a phone _might_ recover from clean water without electrolytes; salt water inside is a killer. Don't know about chlorine. Anyone here good at chemistry?
Exactly. If you know that you have set a specific testing standard in house, but advertise a lesser standard you will always be safe. Some random person can't come in with a water damaged phone and say they only dropped it in the sink and have it be something Apple will believe.
I can't say I blame Apple. It would be impossible to tell what sort of water damage the iPhone had been put through before being ruined.
I mean - say I walk into an Apple Store and claimed that my iPhone 7 was spoilt despite me having dropped it into the toilet bowl for a mere few seconds. The truth could be that I left it in my pants pocket and threw it into the washing machine overnight.
How is Apple supposed to know whether I am telling the truth or not? As long as the iPhone is not 100% waterproof, there will be cases of people ruining it somehow and Apple is simply covering its own backside here.
To cut a long story short - treat this feature as a "glad I had it when things went bad" safety net and not as a declaration that you can now go swimming with your phone on a daily basis.
I'm not a scientist either but my friend Pascal once told me a hole, big hole, small hole, it all doesn't matter. Pressure stays the same.
If not we'd all wear a bucket and dive up all precious treasures in the Titanic.
If you are referring to testing the Note 7, they can't because it is illegal to buy/sell the device in the US. Samsung ordered a total recall, send your phone back, get whatever phone you want
When I was younger, I frequently mixed vinegar and baking soda to create mini volcanoes. So I think I'm fully qualified to chime in on this.
Salt-water would definitely have a bad effect, though any sort of liquid making contact with the PCB while it's turned on won't help. Not 100% on chlorine, but if you think about all the other stuff that naturally comes with chlorine water -- it's likely to be in a swimming pool, with a few other bits and bobs floating about
In answer to your question, I'm honestly not too sure. Maybe my age 5 crayon-drawn science diploma could use updating.
Water pressure is uniform for a given depth, calculated as P=(water density)*(gravitational acceleration)*(depth) or P=(water density)*(depth) depending on units. There's no relieving hydrostatic pressure (at least not in the way being theorized here).
The pressure in [psi] for a given depth z in [ft] for freshwater is: P=62.4/144*z=0.4333*z. For saltwater, P=0.4444*z.

Yes the water pressure inside and pressure outside the bucket are equal.
This is the part I don't understand. If it is certified to survive 1 meter for 30 minutes (or whatever it is) and it falls in my sink for 1 minute at 3 inches and the phone gets damaged, it seems like the warranty should cover it...
Or, more importantly, it get wet this week, sets off the sensor but stops working 9 months from now (probably from something unrelated), is that water damage?
Yes and no. Of course if you bring it down at crazy depth... but the greatest variation is in the first 30 feet - more than 100% variation at around 1 bar.
The video is fun and all, but there's nothing really crazy when you consider so many devices today support 1 bar of pressure...
What is the point of being first if you didn't even read the post. who is the moron here? Lol
The issue here is that IP68 doesn't mean anything because the spec is sloppy (go read it yourself). It means >1m but does not specify a range. I know Samsung says 1.5m but that limit is not the spec definition. IP67 is <1m which actually gives you an idea of capabilities.
I guarantee that every proper IP67 device is technically also IP68 because it only needs to exceed 1m. 1.01m is within the margin or error for IP67, and also qualifies for IP68.
The spec for IP68 reads like it is meant for more serious depth for a short time, because it reads similar to IP69, which just adds more time to exposure.

The holes in the can let the full water pressure in. The can isn't helping the phone, it just helps the guy not lose them.
YouTube channel EverythingApplePro posted a video over the weekend demonstrating how the iPhone 7 fares in an extreme deep water test. The video, titled "How Deep Before it Dies?", shows an iPhone 7 and a Samsung Galaxy S7 being lowered into the ocean at increasingly lower depths.
Apple's iPhone 7 series is certified to IP67 standard water resistance, which means the handsets are built to withstand being submerged in up to 1 meter (about 3.28 feet) of water for half an hour at most. Samsung's handset carries the higher IP68 certification, indicating it can withstand continuous immersion in over 1 meter (3.28 feet) depths, or up to five feet, according to Samsung.
The first test drops the devices down 5 feet, exceeding the 3.28 feet rating that IP67 standard promises. Both devices emerge from the water undamaged. Then the devices are dropped at increasingly deeper intervals in 5 feet increments.
At 20 feet, with no signs of damage, the tester adds another 10 feet. The first signs of damage become evident at 30 feet of water for five minutes. The Galaxy begins sporadically rebooting, while the iPhone's Taptic Engine-based capacitive home button begins malfunctioning.
After 35 feet water immersion, the Galaxy's display refuses to come on, but the iPhone 7 continues to power up and the touchscreen still responds to touches, despite obvious water damage under the bottom half of the display.
Notwithstanding the highly unconventional and extreme nature of the test, it does serve to underline Apple's continuing strategy of being conservative in its waterproofing claims. The first Apple Watch for example was only rated for up to 1 meter of water depth, but regularly survived dives down to 40 meters in swimming tests.

A couple of key points you should correct. The iPhone is not "built to withstand being submerged at 1 meter for 30 meters at most " It's clearly built better than that. Apple only sought certification for that level, IP7, which satisfies the needs of 99.9 % of its customers. Apple wisely is trying not to encourage people to do extreme things.
Second, IP8 is immersion at any depth beyond 1 meter for 30 mins. So a manufacturer can pick an very small and relatively meaningless increment, e.g., Samsung's .5 meter, and get the higher certification. (That's classic Samsung IMO).
Not at all. Is the same as if you enter a box with a few holes. The air pressure would be exactly the same as the one outside the box.

The we know exactly what would happen. People who damage them phones while scuba diving taking pics of fish will claim they just had it it under a meter for less then 30 min.
For those complaining about not leaving the phone for 30 mins, go read the IP67 spec. You'll see that no time is specified.
Also note that Apple does not specify a time for immersion. That means that you cannot use 30min as a metric for Apples compliance.
