Remove the 2 screws near the lightning port with a 0.8mm Pentalobe screwdriver.
Take a hair dryer and heat the display surface for 1-2 minutes at a temperature of 60-70
degrees Celsius.
Fix the suction cup on the bottom of the display and pull the ring up until there is a gap
between the display and the housing.
Insert mediator and disconnect the display from the iPhone case on all sides.
At the top of the iPhone, do not push the mediator much into the case, so as not to
damage the elements from the face id module.
The case opens like a book - the display to the right.
Remove the 2 screws on the small panel and 6 screws on the large panel.
First, disconnect the battery cable and after 3 cables of the display.
To replace the battery in the iPhone 11 Pro Max you need to remove the three silicone
strips from under the battery.
One tape is located near the Taptic Engine, so let's start by removing the Taptic Engine
from the housing.
Remove the 4 screws on the metal panel and remove it.
Under the metal panel, there is a second battery cable, first turn it off and after turn off
the Taptic Engine cable.
Remove 2 screws with a Phillips screwdriver and 1 screw with a 1.5 mm Standoff screwdriver.
Now you can remove the Taptic Engine from the housing.
Remove the 3 screws on the metal panel, then remove it and disconnect the cable from the
iPhone main board.
Let's begin to remove the silicone tape, take the tweezers and peel off the edge of the
silicone tape.
Now pull the silicone tape away from
the battery.
If the silicone tape is torn and remains under the battery, there is nothing critical, now
I will remove the last tape and show how to solve this problem.
One tape torn and holds the battery, take any tool and pry the battery from side where
is no tape.
Now you have two options, you can add a couple of drops of isopropyl alcohol under the battery
where the adhesive tape remains, or take a hair dryer and direct warm air under the battery.
As you can see, the battery removed without any damage.

stick it evenly on top of the battery.

iPhone 11 Pro Max assembled and now you can connect the display and check how the smartphone
works before final assembly.

order, first the display cables.

Remove the silicone adhesive tape from the iPhone back housing.
Using isopropyl alcohol and a cotton swab, you can wipe the back housing, this is not
necessary, but it will not be superfluous.
Before attaching a new adhesive tape, make sure that you glue the right side on the back
housing.
This silicone tape restore resistance to water and dust.
This doesn't provide 100% waterproof for your iPhone but without this sticker, the display
will not hold well and dust will get inside the iPhone.
