this video will walk you through the
process of replacing the battery on an
iphone 12 pro the process of this repair
is almost identical to a battery
replacement on an iphone 12
and while this video can be used as a
reference we still recommend using the
guide specific to your device on
ifixit.com
for this repair you'll need an eye
opener a set of ifixit opening picks
a suction cup or isclack a spudger
some tweezers some isopropyl alcohol
and the following drivers a philips
double zero
a p2 pentalobe a y triple zero
a standoff driver for iphone and a sim
eject tool
you'll also need your replacement
battery and if they're not pre-installed
a set of battery adhesive strips after
this repair your iphone may display a
warning about the genuineness of your
new battery
even when using an original apple part
if your iphone functions normally you
can safely ignore this warning before
you begin your repair make sure that
your battery has been discharged to
below 25
a charged lithium-ion battery can be a
fire hazard if accidentally punctured
to begin make sure your iphone is
completely powered off and then insert
your sim eject tool or paper clip
into the small hole in the sim card tray
press firmly to eject the tray
and then remove it using your p2
pentalobe driver remove the two screws
on the bottom edge of the iphone
to get the front panel off we'll need to
soften the adhesive holding it in place
using a prepared eye opener heat up the
bottom edge of the phone
if you don't have an eye opener a
hairdryer or heat gun can be used
just be very careful as you run the risk
of overheating and damaging your iphone
for the next few steps we'll be using an
isclack to separate the front panel from
the case
if you don't have an ice click check out
our step-by-step guides for instructions
on how to do this procedure
with just a suction cup once your phone
is heated place the suction cups of the
ice clack near the bottom edge of the
phone
one on the front side and one on the
back press the isolect to engage the
suction cups and then close it to begin
separating the screen from the iphone's
case
don't be surprised if your screen
doesn't budge the first time you try
this
the iphone screen is glued on tight but
repeated sessions of heating
and prying will get the job done as soon
as you see a gap between the screen in
the case
insert one of your opening picks into
the gap don't try and completely remove
the screen yet we're just getting
started and this gap is all we need for
now
making sure not to insert your pick more
than a few millimeters slide the
inserted opening pick around the left
corner
and up the left edge of the iphone
slicing through the adhesive holding the
display in place
once you've made it to the top edge
remove your pick and insert it back into
the gap on the bottom edge
now we'll repeat our pick sliding along
the right edge of the iphone
with the sides of the display released
from adhesive it's time to turn our
attention to the top edge
slide your pick along the top edge of
the display to cut away the adhesive
swing your display up from the right
side like you're opening a book but be
careful the display is connected to the
iphone's logic board by several fragile
cables prop your display up at about a
90 degree angle using something like
your iphone's box to hold it in place
using your y triple zero driver remove
the two screws securing the battery and
display connector cover
the screws in the iphone 12 pro are
exceptionally small
so make sure you have an organization
system like one of our magnetic maps to
keep track of them
using your tweezers remove the cable
cover and then using the pointed edge of
a spudger disconnect the battery
digitizer and display cables make sure
to bend the battery cable back slightly
to prevent
accidental contact with its connector
once again grab your y triple zero
driver and remove the four screws
securing the front sensor connector
cover
one of these screws is longer than the
others so make sure to make a note where
all the screws came from
attempting to reinsert the screws in the
wrong location can damage your iphone
using some tweezers remove the cable
connector cover and then use your
spudger to disconnect the front sensor
assembly cable connector
now the display can lift right off to
access the battery
we need to remove a few components
starting with the loudspeaker
using your phillips driver remove the
four screws securing the speaker in
place
and then use some tweezers to lift it
out grab your y triple zero driver
and remove the two screws securing the
sim card reader connector cover and then
use your tweezers
to lift it up and out using the pointed
edge of the spudger
disconnect the sim card reader cable
from its connector on the logic board
and then use your y triple zero driver
to remove the three screws securing the
sim card reader once those are removed
the bracket can come right out with that
bracket removed we now have access to
the final screw holding the sim card
reader in place
and it's a standoff screw if you don't
have access to a standoff bit a flathead
driver can be used in a pinch
just use extra caution when removing the
screw now use your tweezers to remove
the sim card reader
disconnect the taptic engine's cable
using the pointed end of your spudger
and then remove the three screws
securing the taptic engine to the case
two of the screws are standoff and one
is a phillips
use your tweezers to lift the taptic
engine out now we can finally get to the
battery
the battery is glued down by four
adhesive strips two on the bottom
and two on the top each of these strips
has a black pull tab that is taped to
the battery
use a pair of blunt tweezers to peel
back the pull tabs on all four battery
adhesive strips
grab the first pull tab with your
fingers and slowly pull it away from the
battery
you'll need to pull hard enough to
maintain tension on the strip
but don't force it
if an adhesive strip breaks off try and
retrieve it using your fingers or blunt
tweezers and continue pulling
but don't pry under the battery if you
can't retrieve the broken strip
use a little isopropyl alcohol under the
battery to loosen the adhesive
once all four pull tabs are removed the
battery can lift right out
when installing a new battery you'll
need to glue it back in place
if your new battery didn't include
pre-installed adhesive strips check out

and reapplying battery adhesive insert

is properly aligned with its connector

reinstall the standoff screw next to the
taptic engine cable connector
