Welcome to How-Fixit and in this video we will take apart the iPhone 12 Pro.
If you are interested in iPhone 12 disassembly process, I left a link in the description
under the video.
This video is for overview purposes and doesn't include the assembly process.
If you need complete instruction with reverse assembly, in the description I left a link
to a playlist with step-by-step instructions on how to repair an iPhone 12 Pro.
What tools I will use to disassemble the iPhone 12 Pro:
How-Fixit screwdriver set Tweezers
Plastic mediator Plastic tools
and suction cup for removing display
In the description, I left links to all the necessary tools.
Opening the iPhone 12 is the same as usual, still need to unscrew the two Pentalobe screws.
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 degrees Celsius.
In the process of opening the iPhone 12 Pro, you will have to pull quite hard on the suction
cup ring, I think this is due to the reinforced glue used in this phone model.
The iPhone 12 Pro opens like a book, that is, opening the display to the left.
Now the display is thinner and lighter, and now the iPhone12 Pro screen is interchangeable
with the iPhone 12.
Previously, there was no interchangeability between models, but now something has changed
in Apple's policy.
The iPhone 12 Pro's camera module is very similar to the previous 11-series model, but
technically there are changes such as RAW photos, dual optical image stabilization and
LiDAR technology that improves photos in low light.
We will return to the LiDAR module a little later.
The SIM card reader is still a separate module and can be easily replaced.
The module is also interchangeable with the iPhone 12.
The process of replacing the speaker is much easier - no adhesive tape, just remove and
replace.
The speaker housing is the same as on the iPhone 12 and is also interchangeable between
models.
The Taptic Engine is now half the size of the previous iPhone.
Also interchangeable with the iPhone 12.
Removing the speaker and Taptic Engine, we get access to the lower silicone adheseve
tapes that hold the battery, in the upper part there are the same silicone tapes, but
unfortunately, there is a cable close to the battery, which prevents the safe removal of
these silicone tapes.
The Face-ID module is nothing new.
The module did not receive any changes.
Now it is possible to slide the motherboard and access the top of the battery.
Let's removing silicone tapes.
So, we can conclude that in order to replace the battery in the iPhone 12 Pro, you need
to take a lot of steps.
More than 70% of the smartphone has already been disassembled.
The battery in the iPhone 12 Pro has the same number A2479 as the iPhone 12 and is interchangeable
with each other.
On the back you can see the battery capacity of 2815mAh – also the same with the iPhone
12 battery.
To remove the main board, remove the screws on the case to release this cable.
That's it, now we can remove the main board and take a closer look.
Now you can see that this cable is connected to the back of the motherboard.
If you peel off this protective black film, you can see that this cable cannot be disconnected
so easily, because it is soldered to the logic board.
On the Asian versions of the iPhone 12 and 12 Pro, motherboards without such a cable,
and in my case, the iPhone 12 Pro for the US market
This cable directly connects the motherboard to the 5G mmWave antenna module.
In the iPhone model A2341 for the US market, the 5G mmWave antenna module is built into
the side of the smartphone back housing and this is how it looks.
On the outside of the case, this matte area under the power button is the window for the
5G mmWave antenna.
Another antenna module is located on the back of the motherboard.
And now we got to the LIDAR scanner.
This is the same sensor that Apple showed at the iPhone 12 presentation.
The LiDAR 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 and can be easily replaced.
The
light sensor located on a separate cable.
This is a cable with a diode camera flash.
It is very easy to remove this cable, so if the diode is damaged, you can easily replace
it.
Let's see what's left on the iPhone back housing.
In the lower part - cable with a lightning connector, in the upper part - antennas.
In the middle of the case there is a wireless charging module and now it also has a magnetic
ring.
The magnets are located along the edge of the wireless charging coil.
There are 18 small neodymium magnets glued here.
So, the disassembly of the iPhone 12 Pro is complete.
If you need more instructions for all iPhone 12 models in the description you will find
all the links.
Ok guys, that's all, you were on HowFixit and see you next time.
