In case you are wondering, the screen went black around 0:05 because the HDMI cable was bending too much, not because of water. Also at 1:59 what happened is tha the phone simply dimmed its screen. You can see that it's still on if you look closer and I didn't notice it at the time because it worked fine after :)

Was there hot glue on the HDMI and USB cables? Nono coating or not the contracts are exposed.
@@MNSweet Yes 6:51
@@MNSweet Watch the complete video, he explained it in the video.
I wish raspberry pi used HDMI mini instead of micro on the 4/5. The micro connections are really easy to interrupt
You're wrong about the Titan submersible. It visited the Titanic multiple times before imploding. Its ok to lie about politicians but don't lie about a dead guy's invention.
The most mindblowing thing I learned from this video was that there are divers that live under water for WEEKS living in little tubes and breathing bespoke gas mixtures? WTF, that's just crazy.
I'm more surprised by Rolex being in the diving business.
Wtf oi share the timestamp
@@Wunnabeanbag 12:50
samee, i didn't even pay attention to the end of the video bc wth was that?? also why do they bring their watches there with them??
@@reed6514 To those unaware, yes it is a huge surprise, but you wouldn't imagine mine when I saw that one of their oldest models (still made today) is called "Submariner", made for diving and including hydrogen valves since their conception.
Crazier yet is that most Submariners they sell are NOT used for diving, much like how most trucks and SUVs are driven by road kings and soccer moms.
The internal water sensors in phones (designed to be checked so they don't have to cover warranty) can be triggered in high humidity environments, like a tropical location (eg. Singapore). The reason for this is that humidity can get through the speaker gaps.
This means a phone without water damage can be rejected from warranty just because of those sensors. You have to fight to get them to check the entire phone.
I have fought and won 😂😂😂
Those are not sensors. Simple stickers
@@drk_bloodthat sense if water has touched it
Ya litmus papers
@@drk_bloodand a thermometer is simply a liquid
"This watch is specifically made so that it would survive going down to the wreck of the Titanic in the way that the now infamous Titan submersible was not." - woke up that day and chose violence
08:40 if anybody is wondering what that japanese text, under the red circle, means:
エドウイン which is katakana for Edwin. I am pretty sure this refers to EDWIN, a Japanese clothing brand founded in 1969. Very nice.
Correct, it's the name of the brand
You missed the chance to show Samsung Xcover 6 Pro which has a removable back cover with IP68 water and dust resistance. Now people will be mislead by the companies claiming that the only way to achieve IP rating is by sealing everything. But the rest of the video is damn good.
They already are, people who say they need removal batteries get "you'll lose water resistanance" in the reply.
@@FR4M3Sharma Yeah. I guess people will never know the truth unless this comment goes to the top.
He did show the Motorola
@@sajanpreetsingh9144 Yes. He has shown that using Motorola Defy, but the newer versions of Defy no longer have a removable back cover. But the Samsung Xcover 6 Pro launched in 2022 still has a backcover, which shows that companies still could provide that option if they wanted to. Not showing recently available products with back covers in the video would confirm the bias of audience that removable back cover is an ancient practice in tech world and the only way to move forward is gluing things up.
Wow
13:58 Titanic was not designed to go to that depth either 💀
He never said it was designed to go that deep but either way that's where it is
Just a small correction: Water is indeed conductive. It's true, that water is a very poor conductor, but it definitely can conduct electricity. Every chemist knows, that pH 7 means, that there are 10^-7 mol/L H3O+ ions and 10^-7 mol/L OH- ions in water - it's called the autoprotolysis of water - and since there are ions, water is indeed a (very weak) conductor and can therefore destroy electronics by shorting electrical connections. Saltwater has a lot more ions and is therefore much more conductive and can easily destroy electronics. The pressure component you mentioned, just means that the water has an easier way of entereing the phone. And once inside, salt water quickly shorts any connection it can "find".
That also bothered me that He didnt mentioned this behavior
Ok, but anything can be conductive with enough current even wood
This episode of Technology Connections is kinda weird
Why?
C'mom, he didn't even have the magic of buying 2 of the action cameras to tear it apart
It's amazing how different he looks without all that hair!
@@codycastHe's referencing a different RUclips channel that would more typically feature this type of video, lol. Just a joke, not a criticism
@@jessestone117 I was honestly asking why. I didn’t ‘get’ the comment.
distiled water don't remain non-condutive for long after you've contaiminated it (i.e: putting your dirty phone into it), that phone will die sooner or later
Yes the distilled water is a very good insulator
@@manclt704 and an even better solvent
@@manclt704 Yes, but the dirt will cause dissolved ions to contaminate the water, making it no longer distilled and also more conductive over time. If you had a bag of dirt left in a tub of drinking water for 2 hours, would you drink the tub water?
@@robertcarter9800 Yes, indeed you are right, I commented on his demo which was not making any sense to test water resistance with using distilled water as this is not a real-world scenario
@@manclt704 that's true I misread "yes" as "yet" my apologies ☠️
Something that actually accelerates corrosion is electrical charge. Back in the day of removable batteries the best thing you could do to limit corrosion was to take the battery out immediately. As batteries became permanent, the need for water proofing increased significantly
For watches, people have been doing their own DIY hydro mod for ages. The most popular model used have been Casio watches and some have even survived past 2~3k m depth inside pressure chambers
There's also the problem where Apple puts the 20V line next to cpu contacts so it ends up being able to kill your laptop even with mild moisture, dump water on it and you can just wave it goodbye.
Rossman?
So it's no longer the 50v line? (I remember it as that from a few of his vids)
Apple being apple.
Here is what I do because I run several computers(Motherboards) in a moist basement : I wash them fully with WD40 & then liquid detergent. I repeat this again is the motherboard is old, so that corrosion is removed properly. Then dry them fully for couple of days. They I spray them with one thick layer of WD40 and put them to work immediately. The other remedy is to use dissolved grease in turpentine oil which when dried will allow the grease to remain covering all the components. This will last longer than WD40. I have done this to more than 12+ systems/network switches and some of them work 24/7.
I didn't know WD40 was so safe. I usually waited a minute or 2 after applying it on my mouse's button lol.
Thanks for sharing.
@@narutokunn IMPORTANT : After WD40 eats/loosens corrosion, it has to be removed in some way. I use liquid hand wash and an art painting brush. Otherwise the corroded remnants might short adjacent leads. Final coat has to be applied when no corrosion is left around components.
@@prashanthb6521 Wow I learnt a ton from you today. I had no idea about any of this.
My mouse was doubleclicking and I watched a 1min youtube video which suggested applying a drop of WD40 on each button (with no other information). I hadn't even heard of WD40,
It did work but now I know what WD40 is actually doing and potential side effects.
This video after yesterday’s LTT video is why I love the internet, pretty neat coincidence, nice! Great video as always
Which ltt video??
@@Banditxam4 the one where his rack got water damaged
Came here to mention this lol
I am under the water. Please help me. *Water noises*
A missed opportunity. I bet hes punching the air after reading
**boiling the water*
Ok, the water will be gone in 6 hours. Please wait
without you asking how I'm doing? no thank
I found this a lot more interesting than I thought I would. Great video!
How can you sell a product saying it is water resistant and not cover damage from water under warranty?
In my country, companies that sell monitors (computer screens) say that they will not cover you for any damages related to the screen itself.
Water resistant not waterproof
I say the best way still for waterproofing is , silicon gaskets and flap covers for ports and not gkue ! , Samsung Galaxy s5 and Lg g4 had waterproofing rating with removable back cover that shows the potential ! . The real reason why company's dont really push for waterproofing is purely for their monetary purpose. I doubt a smartphone with silicon gasketed back cover along with nanocoated internals and a flap for usb c would be even sea waterproof for 2-3 meters !
0:40 The purpose of filling the watch case with oil is more about eliminating serious pressure difference than making it resist water.
If you watch the rest of the video you will see me explaining exactly this ;)
What I found really nice on cheaper phones is that they have resin on the tiny surface mount devices on the motherboard.
Those tiny components are protected from water using a resin barrier in addition to a gasket around the Type C port and headphone jack. My spare phone doesn't even have an IP rating but it has survived contact with water plenty of times.
2:20 water with salts does not have free flowing electrons. When you disolve a salt into water it splits into positive and negative ions. These ions will flow freely, allowing electricity to flow.
Watercooling: you are doing it wrong
For the first time in a while, this coverage is actually useful.
This is more tech than any youtuber reviewing smartphones. Thank God!
Nice video, but one has to wonder how many raspberry pis are going to die because of it.
The initial impression was that it was a regular pi in a water jar, leaving those clarifications until minutes later...
(Just like the recharging a phone in the microwave thing...)
When using underwater cases, sometimes using a bit of silicone grease to improve sealing.
Thank you, this was useful.
Banger informative video. The way things are explained is amazing.
"You see, the phone should continue working just fine"
Phone dies. :)
It might be power saving that dims the screen tho
@@Aera223 Could be. I have no idea how that phone works. My devices all go to a lock screen. This one went completely black right then, so bad timing if so :)
@@Psychlist1972 check the pinned comment! He has mentioned it
12:30 Liquids aren’t much harder to compress; they don’t compress at all (this is how hydraulics work); the issue with oil filling is when there is air because air is VERY compressible 😊
A simple google search will tell you otherwise. Liquids are just so close to being incompressible that people treat them that way, but they are in fact the tiniest bit compressible.
Didn't know consumer stuff used paralene. It's a pain to mask stuff off and run thru the vacuum chamber. Since it's a solid dimer that boils into a gas and polymerizes on surfaces in the chamber you control thickness by calculating total surface area of the chamber plus your assemblies and load the required amount of powdered. No idea why they hype it as nano, been around for 60 yrs.
Just use pure water and electronics won't mind
2:00 but the touchscreen
That's auto dimming
regular pure h2o will still conduct electricity. water normally does not stay as "noble" water molecules but rather an H ion and an H30 ion. so over time, de ionized water will not remain nonconductive (especially if you dip your metal heavy phone in it). even if you're super careful about keeping out external ion sources.
this is why there is a difference between deionized water and distilled water.
also meterials like goretex (and maybe the mic and speaker holes, i dk) are coated in some type of PTFE-adjacent coating. This (along with the physical aspects that you describe) keep them water repellant.
super interesting video dude!
gonna use this when i get asked about waterproofing
7:42
Oh neat! The Defy+ was my first smart phone! It was also my introduction to custom ROMs, flashed cyanogenmod on it to get Android 4.
i'm a bit disappointed, conformal coating wasnt mentioned. it's widely used in the drone hobby, and effective enough, you can launch a drone with properly coated electronics from a pool of water.
I didn't expect this video to tell me so many titbits I didn't know about. Great one.
9:18 being nitpicky here, but isn't the pressure from a wave (with a bubbly surface) magnitudes lower than the pressure from a flat water surface, with all its surface tension? Like dropping a watch into a calm pool will most likely kill almost every watch, except those rated for IIRC 10 bars or more. A wave that strong will kill anyone instantly.
If you like watches with Oil in them, look up Ressence Type 3. The tech in that is wild.
Sehr informatives video, danke! 😄
Reminded me about biggest tech you tubers saying Fairphone water proof was fake because water got in. Good to know about that protective coating
Youre simply the best
10/10 content, m8
_Yknow there are water coolers for Pis nowadays_ :P
Absolutely mindblown!
0:25 as long as its completely distilled and deionized water it should actually run without too much problems
Especially with 5v
Now add some salt or minerals or some free ions in the water
Get a liquid resistor....and start electroplating shorts
Pure water is actually a terrible conductor or electricity and heat
11:29 That is not silicon, but it is silicone.
Thanks a lot! I was looking for something like this... but found out that it's hazardous pollutant (toxic and cancerogenic) x)
I dropped my fold 5 in the river 2 weeks ago. I freaked out and dried it off asap. Turned out it seems fine now. Hopefully it really is as I may never know.
amazing video as always!
nagyon tetszett hogy milyen sokféle példát bemutattál!
Wahnsinnig gutes Video!
Und exzellentes englisch :)
Now I wonder who will ever need a watch for diving to over 3km depth ... and survive!
I wonder what are the conductivity and corrosion like in a children’s pool
Aren't these nano coatings basically pfas/ppf's that are quite shitty for the planet?
Some definitely are. The parylene mentioned in the video is a PTFE alternative (non-PFAS) that's considered safer, though I don't imagine that means "harmless".
But if it works you are more likely to keep device for longer.
I know I don't give a shit about the planet.
@@arkhalis3682it's really about your health as well
The 0.0056 g of nano coating is nothing compared to that 4500mAh Lithium and Cobalt battery in the phone you’re using to watch this 💀
So you're saying my childhood fantasy of a computer case filled with water for better heat disposal is achievable?
you say parylene is applied with chemical vapour deposition but you described physical vapour deposition. Is the actual parylene being injected or is it a precursor that reacts into parylene in the chamber?
7:45 a quick note, Motorola revoked the certification not that long after launch, as it turned out not to be good enough and produced a lot of troubles for everyone involved.
Omg, i had one of those Motorola Defy phones. At its time it was so cool. Also waterproof with removable battery. The thing these days is just impossible to get.
giggles at the titan joke gj
That Titanic-depth watch didn't survive it, and when I put in a warranty claim, guess what they told my lawyer.
Were you afraid to sink that phone? I was.
Just being resistant to water is not enough. Most water that comes on contact is usually diluted with things like soap, bodily oil, lotion and sunscreen. Should be chemically inert as well.
Looks to me that the phone you put in distilled water actually DID die (or have issues) just before you cut the video :)
He addressed that in the pinned comment that it just dimmed the screen & was fine after.
I really wonder what the protection against water and dust will look like when the EU law on repairs comes into place.
For some reason, I missed many texh altar videos on my yt subscription feed, weird
Actually, "pure" water will still have a pH, so not only H2O molecules. If you wanted water to not rip itself apart, you need to be at absolute zero or a single molecule in a vacuum.
Trust nothing! Conformal coating! xD
There is tradeoff here. Those materials are probably thermal insulators as well and manufacturers can not coat every part but put silicon sealers around.
Btw, did you lose weight? Formula please :)
You are my professor proton
We could also just distill all water on earth and our electronics would be save forever. Easy Peasy.
2:13 ter is taht most water isnt pure and has ions
Randomly throwing shades at Titan
To be fair, the temptation was too high not to do so
@@Connie_TinuityError I mean I get it
Watching this after I lost phone screen to water damage
I dropped my fairphone 3 in water, only shortly, but it works for over 3 years now
Distilled water isn't water conductive. You can just use a jug of distilled water and any computer will work
My parents had the defy! I had the defy mini. To this day, I dont understand how we put up with these tiny screens, practically unusable keyboards and horribly laggy software... Early android days, huh.
am i water proofing my whole house now, thanks...
All watches can go as deep as the Titanic. Only a few of them can go that deep and still work, but you forgot to mention that in your outro.
The exact quote was: "This watch is specifically made so that it would *survive* going down to the wreck of the Titanic [...]", the emphasis on the word "survive"
@@TheDoubleBee No, what he said after he was done talking about that watch in particular.
HAHAHAH.. now you can die in deep sea, but your Rolex will still be of value and working :))
Does the waterproofness on action cameras also expire?
Any watch can go as deep as the titanic 😁
Yo can u make a video on HMD Globals Nokia.
Brilliant
... oh i've been using my water resistant phone in showers and stuff bc of its ipx rating but i guess i dont want it to corrode just in case
it's ip68 soo
Nice
Have you tried asking the water nicely?
Red Shirt Jeff but no exquisite violence
I see a Tech Altar video I click
Ehh, Motorola Defy was released 2021.. It looks essentially like they copied my Sony Xperia Active from 2011.. That phone is waterproof and beerproof! (Yes, I had a long going gag to drop it in my beer while in the bar and seeing people freak out. The phone itself still works, it has just gotten left out of updates and software support).
it was also rated IP67
Maybe search again. There was a Defy in 2021, but it's not the first one and not the one I showed in the video
Solution to the pressure issue, don’t place ATMs on your phone
Did the phone fry once it was dunked it for a while and he kept pretending that it was working ?
Read the pinned comment
TechAltar, the next Taras Kul _(CrazyRussianHacker)._
Wow how did they make a computer cost around 40 $ and still be waterproof 😅
You could've just used a multimeter instead of a phone that could have dust inside it.
Awesome
at this point just put your phone inside a ziplog bag.
Does that mean IP68 will become less imp?
0:40 The watch has no electronics, it’s all mechanical.
Water and eletronics is fine, eletronics in water with impurities is not
I put my water resistant phone in a water proof pouch and it turns out none of those things are true,, the pouch immediately filled with water and so did my phone, broke instantly
