instructions in the description below
start by heating up an eye opener and
place it on the bottom edge of the
phone's back cover
leave it there for about two minutes
then apply a suction handle on the spot
you just heated up
and pull it with a strong steady force
this will create a gap between the cover
and the frame for the next step
warning do not apply excessive force
with the pick while cutting the adhesive
during the next few steps
or you might crack the back cover glass
when you see the gap
grab an opening pick and insert the
point into the gap so that the adhesive
doesn't re-adhere
this may take more than one attempt due
to tight tolerances
if so apply more heat once you have your
pick inserted
slide the pick back and forth along the
bottom edge making sure you slice
through
all the adhesive then leave a pick in
the seam so that the adhesive doesn't
reseal
next grab your eye opener again and heat
the left edge of the back cover this
time
and insert a pick into the middle of the
phone and slide it toward the bottom
when you're done cutting all the
adhesive there leave the pick at the
bottom edge and grab another pick
and slide it to the top edge
now repeat the same process on the right
edge
once that is done use your eye opener to
heat the top edge and use your pick to
slice through the adhesive there
when slicing around the corners at the
top be careful because the curved edge
is very susceptible to cracking
be very gentle once you have released
all the adhesive you can remove the back
cover
now go ahead and use your spudger to
disconnect the wireless charging coil
connector
use a pair of tweezers to gently peel
the wireless charging coil up and away
from the phone
next grab your driver and remove the
five phillips screws securing the
motherboard bracket
then with your tweezers unclip and
remove the bracket with your spudger
disconnect the battery connector and
then use your driver to remove five more
phillips screws securing the loudspeaker
and the lower mid frame
insert your tweezers into the notch at
the top left corner of the lower mid
frame and pry up to release the clips
holding it in place
it should come right out next disconnect
the main and auxiliary cables from the
daughter board
then repeat the process for the two
cables on the motherboard now you can
safely peel those away
pry up and disconnect the 5g antenna
cable from the left side of the
motherboard
and finally disconnect the main display
flex cable
gently peel up and move the display
cable and 5g antenna cables away from
the motherboard and battery
now on to the battery grab your
isopropyl alcohol and apply it to the
gaps between the battery and the frame
on
all four sides make sure you tilt the
phone in different directions so that
the alcohol spreads out underneath the
battery as much as possible
this will take about two to three
minutes for the alcohol to start
softening the adhesive
apply a suction handle to the center of
the battery and hold on to the top
and bottom of the phone now firmly pull
up on the suction handle
if the battery doesn't move add more
isopropyl alcohol and try again
when the battery does begin to lift keep
lifting until it is separated from the
phone
before you install a new battery you
will need to remove the old adhesive in
the well
using some isopropyl alcohol and the
flat edge of a spudger if you need it to
install your new battery
place some adhesive in the well and then
lay the battery on top and press it into
place
if your battery came with pre-applied
adhesive you can just remove the liner
and place it in the well
flip the display cable and 5g antenna
cable over and reconnect both to the
motherboard
then reconnect the main and auxiliary
cables on both the motherboard and
daughter board
making sure they are oriented the
correct way
go ahead and connect the battery cable
but before moving on
make sure that the phone powers on and
everything is working properly
if it is power off your phone and
disconnect the battery again
now go ahead and reinstall the
loudspeaker and screw it back into place
you can now safely reconnect the battery
next
lay the motherboard bracket back into
place and reinstall the screws securing
it to the phone
grab your wireless charging coil and
connect it first so that it is properly
aligned
and then you can press it down into
place
before you close up your phone be sure
to apply new adhesive to your back cover
we have a video that walks you through
this process linked in the description
below
lay the back cover onto your phone and
press it firmly in place
then be sure to set some weight like a
book or a tool kit flat on the top of
the phone for at least 30 minutes so
that the adhesive seals tight
once your phone is sealed be sure to
calibrate your new battery using our
guide over on ifixit.com linked in the
description below
