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.

Apple doesn't have to believe you. They'll look at the water damage strip and deny warranty.
 
While the test itself is fine since both phone were subjected to the same conditions. However, the test didn't really replicate the actual pressure at the those depths given that they were sitting inside a metal container (albeit a perforated one). I'd imagine that the container would significantly alleviate the water pressure on the phones? Maybe putting the phones in net instead of a metal container might be a better option?


Let me guess. You slept through Physics 101, right?
 
The real test is to sink the phone in 5 feet of water WITH OUT THE PAINT CAN! Even with the "hole's" punched in the cans, it doesn't make the water pressure inside the can equal to the water pressure outside of the can.

Mark, Mark. Mark..

LOL. I guess physics isn't your thing, eh?

The main issue I have with the test is that they didn't really test to IPxx specifications, which are 30 minutes at a specified depth.

But it's still an interesting test and inspires confidence for short duration accidents like dropping a phone in a pool or the like. Though they could have told the story in less than 15 minutes! Sometimes video just isn't an efficient means of communication...

As a certified SCUBA diver, don't worry about the paint can. The test is fine.
However you want to define your water resistance marketing, both the iPhone and Note meet their adversed goal. And since IP67 and IP68 are a meaningless distinction, they are roughly equal to each other.
I'd give the edge to Samsung though, purely because their warranty covers water damage.

While I understand your confusion because it has been endlessly reported. Neither the IP67 or IP68 certifications include a time restriction of 30 mins. That time comes from Samsung's marketing claim and has been badly reported to apply to all IPxx products. Since Apple doesn't make a 30min claim themselves, their product doesn't need to meet that standard.

Are you saying that pressure inside the can is the same as the pressure outside of it? If so, please offer up a short explanation. I was confused about it which was why I posted my comments with question marks. Please enlighten me, channel your inner Isaac Newton.
 
I know the can had a hole in it to fill with water, but does that interfere with the actual water pressure being applied to the phones?

I'm not familiar with this stuff, but it seems the can would take a lot of the water pressure first before the phones are exposed to it. Would this be the same as just weighting the phones from below and having them fully exposed to the water without a can around them?

Only if the can were sealed to completely prevent any water entering. As soon as the can fills up, the pressure inside is the same as outside the can.
 
:p:p:p
Meanwhile, at Samsung's underwater testing facility:

Wait, that is the North Korean facility, right?/s:p
 



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.

Ocean? No. Not even close.

The test was conducted in the Columbia River far far away from the ocean. The river is fresh water. The ocean is salt water. Test results would likely be very different if conducted in salt water.

Seriously, did the writer or editors even watch the video?

And to those of you who question the water pressure in the bucket, I just shake my head. There are many holes in that bucket. All it takes is one. Even if the bucket remained dry inside, the atmospheric pressure inside would equal the water pressure outside.

The multiple holes would allow it to form a pressure equilibrium with the surrounding water fairly quickly (air flows out, water flows in then. Eventually as much water flows out as in and you have an equilibrium.) Now, I didn't see a hole in the top so it's possible that air above the highest hole may be trapped in if the can is held in a completely vertical orientation.
 
I'm glad the iPhone finally has some waterproof capability. I think it will make using this iPhone as a bike computer a lot more common. I've been caught in the rain before with my phone, and with the case I have, I've been lucky. But, I would like to see a commercial with someone running and bicycling in the rain.

Water molecules are in constant motion. They move inside of and out of the can. They do so naturally until as many molecules are flowing into the can as out of it. This is an equilibrium state. In order to have a difference in pressure, you need something to withstand the force of the water wanting to get in (and air getting out) and reach equilibrium. An intact paint can will do this until it gets so deep that the force of the water is greater than the force of the air inside and aluminum wall can push back and the can would crush. But... if you put holes in the can, there is no barrier.

This truly is VERY basis physics/physical chemistry. I hope you're middle-school aged or younger.

There were two holes in the lid.

Even if the can remained dry inside, it takes only one hole to nearly instantaneously equalize the air pressure inside the can to the water pressure outside the can.

Did some of you never play with bath toys when you were younger? This common sense stuff does not require a degree in physics or even scuba certification. Go jump in a swimming pool and figure it out! Feel that pressure on your ear drums and inside your sinuses?
 
Curious for how long the iPhone will work.

I dropped my 6s in the lake near our dock and it fell down to about 8 feet of water and was there for about 10 minutes before I finally found and retrieved it. Read: 6s, NOT the water resistant 7. It was still working when I recovered it. Touch screen still responding so I could power it down, despite water clearly inside the device. Put it in rice (You know, that old wives tale... why not) and it never recovered, with lots of internal corrosion and warping evident after the fact. Replaced at the Apple Store for $300 (I didn't have AppleCare, unfortunately. A mistake I remedied with the pre-order of my 7+)

Truth is, lots of electronics can handle being completely submerged in water for a long time; the issue is the minerals in the water eventually causing a short, and the fact that the components in an electronic device can actually dissolve in water further causing shorts.

So far, I've not been impressed with pulling a phone out of water and it still working; because my non-water resistant phone did that. So did an old Palm OS device many years ago, long before the iPhone. Same thing, dropped it in deep water, recovered it, still worked long enough to power down. That one I was able to recover by disassembling and cleaning parts out with alcohol. 100% functionality restored. The key difference being, I could REMOVE the battery. With the iPhone, once the battery shorted (As I expect it did as the device got very hot after a few hours), it was all over.

Thanks, I didn't know.
 
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.
