Hi everyone, Welcome to How-Fixit, in this video I will disassemble the iPhone 12 Pro
Max and together let's see what's inside this smartphone and compare it with the iPhone
12 Pro.
In the description under the video, I left links to disassemble of all iPhone 12 models.
By the way, This video is for overview purposes and doesn't include the assembly process.
If you need complete instruction with reverse assembly, in the description you will find
links to a playlist with step-by-step instructions on how to repair iPhone 12 Pro Max.
What tools need to disassemble the iPhone 12 Pro Max:
HowFixit screwdriver set Tweezers
Plastic mediator Plastic tools
and Suction cup for removing display In the description, I left links to all the
necessary tools.
The disassembly process doesn't differ from previous models.
Still need to remove the two screws near the charging port using a 0.8mm Pentalobe screwdriver.
To open the case, it is enough to warm up the display surface even with an ordinary
hair dryer for 3 minutes at a temperature of 70-80 degrees Celsius.
The case of the iPhone 12 Pro Max opens like a book, that is, turn the display to the left.
The display module in iPhone 12 Pro Max is the largest and thinnest of all previous generations
of iPhones.
In the iPhone 12 Pro Max, the telephoto camera has a better optical zoom than the iPhone
12 Pro.
You can see Differences in the sizes of the camera modules when comparing.
So, the Pro Max camera module is larger than on the 12 Pro.
Сamera lens is slightly larger and because this zoom is better.
The bottom speaker is very easy to remove.
No more adhesive tape or ribbon cables.
If you compare the size of the speaker case to the iPhone 12 Pro, you can see that on
the Pro Max the bottom speaker is slightly larger.
The
Taptic Engine in the iPhone 12 Pro Max looks like the vibration motor from the iPhone 12
mini.
Compared to the 12 Pro, you can see that the module a little bigger.
Let's move on to the battery.
It is glued to the back housing with silicone adhesive tapes, nothing new here, and now
we will remove them.
I love these sounds, and I love when these silicone tapes tear
By the way, in the upper part of the battery there is absolutely no place to pull this
tape at a convenient angle, of course there is a higher risk that this tape will tear.
iPhone 12 Pro Max comes with the largest battery at 3687mAh.
This is 872mAh more capacious battery than the 12 Pro.
Comparing these batteries, there is a clear difference in size, but this is not surprising.
The Face-ID module is the same as before, also has an infrared camera, a dot projector
and a front camera.
All the same as on previous iPhones.
The SIM card reader in iPhone 12 Pro Max remains
a separate module from the motherboard and can be quickly removed and easily replaced.
This ribbon cable is connected to the back of the motherboard, you cannot disconnect
it because it is soldered to the board.
You can find this cable on all iPhone 12 Pro Max motherboards, but only for the US market.
IPhone 12 Pro Max for the Asian and European market does not have such a ribbon cable on
the motherboard.
So why is this cable here?
This ribbon cable directly connects the motherboard to the 5G millimeter-wave antenna module (mmWave).
In the iPhone 12 Pro Max model A2342 (for the US market), the 5G mmWave antenna module
is built into the side of the smartphone backhousing and this is how it looks.
On the outside of the backhousing, this matte area under the power button, this is window
for the 5G mmWave antenna.
Another antenna module is located on the back of the motherboard.
What does it all mean?
All iPhone 12 models support 5G bands sub 6 Ghz and in the iPhone 12 for US market with
5G mmWave module gives an additional 2 bands n260 and n261.
So, this mmWave is a set of 5G frequencies that gives ultra-fast speeds at short distances,
making it best suited for dense urban areas.
These are light sensors and now located on a separate cable.
And now we got to the LIDAR scanner.
This sensor improves the quality of photo (especially in low light conditions).
Also with this sensor, the iPhone makes measurements in space more accurately.
It's great that this sensor is separate from the camera module.
The ribbon cable with the diode is very easy to remove and, if the diode is damaged, it
can be easily replaced.
Let's see what's left on the back housing.
In the lower part - cable with a lightning connector, in the upper part there is an antennas.
In the middle of the case there is a wireless charging module and now it has a magnetic
ring.
18 small neodymium magnets are located along the edge of the wireless charging coil under
this black film.
So, no more surprises from Apple, iPhone 12 Pro Max teardown is complete.
In the description I left links to all instructions for the all iPhone 12 models.
That's all, you were on HowFixit, and see you next time.
