Samsung Note 10+ Teardown – TWO Wireless Chargers?

Samsung Note 10+ Teardown – TWO Wireless Chargers?


The Galaxy Note 10 is usually the Swiss Army
Knife of all smartphones. It’s the phone that has everything and can do everything…or
at least it used to be before Samsung removed the headphone jack. Today we’re going to review
the Galaxy Note 10+ from the inside, see what makes it tick, and see if there was actually
room for that jack. Let’s get started. Let’s get started. You have to hold the power
and volume down button at the same time to turn off the phone…because that makes a
whole lot of sense. Let’s get started. [Intro] This video is actually going to be super interesting.
The Note 10+ is arguably one of the most feature-rich smartphones on the market right now. To remove
the vivid back panel, we’ll break out the heat gun. Glass and metal sandwiches tend
to all be built the same. With a glass panel, I do have to take special care not to flex
the glass too much or the whole thing might shatter. Once the adhesive is warmed up and softened
underneath the glass, my suction cup can pull up and my razor blade and pry tools can slice
through the adhesive that’s holding the panel to the frame. It’s a very tedious process.
The inexpensive plastic Galaxy A50 was just as colorful as this Note 10, and it used a
plastic panel which is way more durable than glass. One thing that makes this Note 10 even
harder than usual to open up is the curve of the glass that wraps around the side portions
of the phone. Any pressure in the wrong spot along that curve might shatter the whole panel.
With enough time, patience, and a slight headache from looking at this flashy tie-dyed tech,
we finally get the back panel to separate from the phone. The rear glass doesn’t have
any electronics attached to it. All the wireless charging is built into the phone body. To go deeper, we’ll have to remove 14 normal
Phillips head screws. Thumbs up to Samsung for not using proprietary screws. Once those
are out I can fold over the metal plate and unplug the golden battery connector. The wireless
charging coil is plugged in right next to it. Unplugging that releases the wireless
coil from the phone. You might be thinking to yourself, ‘Hey Jerry, why do you keep calling
this black sheet a coil?’ That’s because it is. You can see the circular shape of the
copper windings underneath the black covering. These internal copper windings inside the
Note 10+ will rest on top of the copper windings found inside of a wireless charging pad. The
pair of coils creates an electromagnetic field through which energy can transfer into the
phone. This might come as a surprise, but this large wireless charging coil isn’t the
only wireless coil found inside the Note 10. On the left side of the phone we see a large
rectangular housing. This is used to store the s-pen, and at the very top of that housing
where the tip of the pen sits when it’s parked inside of the phone is a little baby wireless
charger. I can peel off the black tape to reveal the miniature copper coils that sit
right on top of the coils wrapped around the tip of the stylus. Once again creating two
sets of coils that form another smaller electromagnetic field. Power flows from the phone battery
through the two coils and into the s-pen capacitor which we discovered when we carefully disassembled
the s-pen in the durability test video. This wireless transfer is also why the s-pen cannot
be made from metal since metal obstructs wireless charging. It’s some pretty mind blowing tech
and we’ve barely even started this teardown. Let’s pull off the top black plastics. This
reveals a dual colored motherboard – both blue and green. A transparent Note 10 would
look pretty awesome. I’ll unplug the power and volume buttons. The connectors just unplug
like a little Lego. I can remove the front facing camera. It’s a 10 megapixel little
guy with no optical image stabilization. The black square here in the center of the motherboard
is the earpiece strangely enough. It’s in a weird location. We’ll dig more into that
in just a second. I’ll pop off the three ribbon cables down here along the bottom of the motherboard,
along with another ribbon on the right side, each unsnapping like a little Lego. Then I
can remove the SIM and SD card tray. Remember that Samsung made three versions of this phone.
The regular size Note 10 does not have an SD card slot. The dual colored motherboard can lift away
from the phone housing at this point. The reason why this motherboard has two colors
is that it’s actually two motherboards stacked on top of each other. Kind of like what we
say inside of the newer iPhones. It’s a thick sandwich of really expensive technology. Surprisingly
though, even with the extra thick motherboard, there’s no thermal paste on the back, just
a gray foamy pad looking thing. Let’s take a look at the cameras. This block
of cameras is another piece of mind blowing tech. The Note 10+ wide angle camera is up
top with no optical image stabilization. Then there’s a regular 12 megapixel normal camera
which does have OIS. And then a 12 megapixel two times optical zoom camera at the bottom.
This also has OIS. Samsung is the only manufacturer to release a variable aperture camera unit.
Just like, you know, your pupils are just inside of your eyeball to get the optimal
light for your eye. This little circle opens and closes to get the optimal amount of light
for Samsung’s camera sensor, depending on the situation. It’s pretty cool. The lens on the right side is a depth sensor.
We’ve seen this pop up in a lot of phones lately and it’s only available on the Note
10+. We’re going to check out the copper cooling pad here in a second, but first we need to
uncover the charging port. The black plastics come off easy enough since we already took
out the screws. The plastics contain the bottom loudspeaker. It’s got the same little baffle
balls hidden inside the speaker like we saw in the OnePlus phones. It’s a little ball
pit for ants. I’ll remove the two extension ribbons and
the three additional screws. Then the whole little charging port can come away from the
frame of the phone. With the Galaxy S10, this port was not replaceable so I’m glad Samsung
changed their minds and didn’t permanently attach the charging port to the motherboard
again. Another change is that now we have a square vibration motor. This probably contains
a similar taptic feel that the iPhones have. And we also have the same water resistant
mesh over the speaker and microphone openings that we’ve seen inside the phones for a couple
years now. These help the Note keep water out for its ip68 rating. What about the question: Is there actually
room in here for the headphone jack? The answer is yes, there is always room. The circuit
boards can be designed and rearranged however Samsung wants. Proof of that is here with
the double stacked motherboard. Stacking the motherboard allows for more room. They could
just have easily stacked parts of the lower charging port board and added the headphone
jack at the bottom. Or stacked more of the upper board onto each other to make room for
the port up top. Easy peasy. It’s no coincidence that Apple removed the headphone jack at the
same time they launched their wireless air pods. Or that OnePlus lost the headphone jack
when they launched their bullet headphones. Or even the Pixel lost the headphone jack
when they launched the Pixel Buds. And now Samsung lost the jack as they push their wireless
Galaxy Buds. Coincidence? Absolutely not. Removing the jack coerces customers into buying
additional technology from the same company who made your phone. Companies know this and
companies like this. Another thing companies do is make your phone harder to repair so
that instead of fixing it, you just go buy a new one. And Samsung is just as guilty as
the rest of them with this permanently glued in battery. Each bend of this battery as I
try to remove it, is super dangerous. The internal layers could pinch together and short
out at any moment, causing a fire. You would think that Samsung would want to avoid exploding
batteries and just add easy to remove pull tabs like Apple does, especially considering
their history. And as the largest smartphone manufacturer in the world, Samsung should
be leading the way with battery pull tabs or gentle adhesive so that one, I don’t blow
my fingers off, and two, so that I can stop saying Apple has them beat in one area. That’s
more painful than losing a finger. The battery of the Note 10+ is a 4300 milliamp
hour. The regular Note 10 would be a 3500 milliamp hour. Another mind blowing piece
of tech inside this Note 10+ is this super slim under screen fingerprint scanner glued
directly underneath the screen. During my Galaxy S10 teardown video I broke open the
whole phone to show the insides and talk more about how this works. Today though, I’m going
to keep the Note 10 in one piece so hopefully it will still turn on when I put the whole
thing back together. Seeing the outline of the scanner with my LED light is pretty cool
though. There are a few things left before we reassemble
the phone. A water damage indicator sticker here next to the SIM card tray opening. And
then we have the earpiece which is strangely pretty far away from the actual earpiece grill
location. Popping it out reveals that it is indeed a speaker and not the under display
vibrating technology we saw inside the LG G8. It looks like the speaker fires downward
into a hollow channel between the frame and the screen. Then the sound is directed up
towards the top of the phone to eject out the hole near the SIM card tray. There’s also
a super incredibly thin opening between the front glass and metal top of the phone. It’s
pretty hard to see since it’s only 5 human hairs thick. I actually use human hair to
measure everything which explains a lot. Finally we come to the heat pipe or vapor
chamber as Samsung calls it. We normally only see this type of cooling in high end gaming
phones like the Razer Phone 2 or the Black Shark 2. It’s cool to see the technology making
making it’s way into non-gaming phones. As we know, solid copper is a great conductor
of heat. It pulls away heat from hot objects like processors and goes and dissipates that
heat elsewhere inside the phone. Heat pipes are more efficient than a copper slab because
of the liquid inside the pipe. The vapor chambers like the one we see here take cooling to a
whole new level – beyond that even of heat pipes Slicing the vapor chamber open, we can
see that it’s a hollow pouch with plenty of room inside for liquid to move around. The
liquid will vaporize at one end where the processor is heating up, and then cool down
as it reaches the far end of the chamber. Only to be wicked back again to the processor
by the copper strands and copper mesh capillary action so it can start the whole process over
again. It’s kind of like a liquid cooling system built for PCs but crammed down into
a really small space. The liquid is still present here in the pouch even after I opened
it up and messed around at the insides. The wire wicking mesh is pretty interesting.
The copper vapor chamber does a good job of helping the phone run efficiently, but it’s
not mandatory for functionality. The phone should still work and turn on without this
in place. We’ll see if that’s true in just a few seconds as we assemble the phone. The Note lineup used to be the absolute pinnacle
of everything that Android phones were capable of, so I’m sad to see now that Samsung dropped
even one useful feature like the headphone jack. But even without that feature, it’s
still one of the most, if not the most, well-designed and feature-rich cellphones you can buy right
now. So if you’re looking for the best of the best, and willing to pay a premium for
100% of what smartphones are capable of right now, this is probably the phone to get. Just
keep in mind that you can probably get a perfectly decent phone that does 90% of what the Note
10 does for about half the cost from someone else. Smartphones decrease in value faster than
a piece of used gum, so unless you make money with your smartphone, you can always just
go get last year’s version for a fraction of the price. There aren’t very many substantial
improvements between one year and another. Would you look at that. The whole thing still
turns on. Gotta love that. The Note 10+ is a very tempting phone. I’ll probably upgrade
at some point in the future when there’s a price drop or I can find a good deal. But
for now I’ll just stick with my 2 ½ year old Galaxy 8+ for a little while longer. Hit that subscribe button if you haven’t already.
It’s free and you get to see the insides of every flagship phone…which is like, you
know, super interesting. Come hang out with me on Instagram and Twitter. And thanks a
ton for watching. I’ll see you around.
