the iPhone 10s has one of the longest
lasting batteries ever found in an
iPhone yet but even the biggest
batteries can't last forever and one day
you'll need to replace it so today we're
gonna show you how for this repair
you'll need an eye opener a set of
iFixit opening pics a suction cup an ice
lock a spudger tweezers and a p2 pen
Loeb tripoint wide triple zero and
Phillips triple zero screwdrivers we
also recommend using a magnetic mat
during your repair as the iPhone 10's
has a ton of tiny screws that are easy
to lose track of when you're ready to do
your repair discharge your phone below
25% to reduce your chances of a battery
fire or explosion
if you accidentally puncture your
battery but don't worry this probably
won't happen it's just a precaution
power off your iPhone and then start by
removing the two P two pentalobe screws
at the bottom of the phone
next use your eye opener to heat up the
lower edge of the iPhone this softens
the adhesive making it easier to open if
you've got an eisbock it's gonna make
opening your iPhone a lot easier
displace it on the screen just above the
Lightning port engage the suction cups
and squeeze to open the phone
you only need to open the iPhone just
enough to get one of your opening pics
inside if you don't have a nice clock
handy a suction cup can be used in the
same way place the suction cup in the
same position just above the Lightning
port and apply constant pressure to
create the gap needed to insert the
opening pick once you've got the opening
pic in position between the phone's
frame and the screen slide around the
lower left corner and then up the left
side of the phone slicing through the
adhesive while making sure not to insert
the pic too far into the phone this is a
good time to remind you that breaking
the adhesive seal of the iPhone does
compromise your phone's water resistance
so keep that in mind you'll need to
replace the adhesive or just keep it
away from water after this repair now
reinsert your pic at the bottom edge of
the iPhone and slide it up the right
side to finish separating the adhesive
the top edge of the iPhone tennis is
secured by both glue and clips so slide
your pic along the top to separate the
adhesive then gently wiggle the screen
down in the direction of the lightning
port try not to pull the phone too hard
there are several cables connecting the
display to the logic board and we don't
want to damage them
once you've freed the display open it to
the right like the back cover of a book
prop the display against something to
keep it open and then remove five screws
holding on the logic board connector
bracket there are three different size
screws in this bracket and they all need
to go back in exactly where they came
from so make sure to note which screws
came from which hole on your magnetic
map use your spudger to disconnect the
battery connector the front panel sensor
assembly cable and finally the OLED
panel connector
the sensor assembly cable is lightly
adhered in place so use your tweezers to
gently lift the cable until it separates
now your display should lift right off
before we can get our battery out we'll
need to remove the bottom speaker and
the taptic engine and to get started
we'll take out the five screws securing
the two brackets that are below the
taptic engine
next there's one screw securing the
speaker connector cover then use the
pointy tip of your spudger to disconnect
the speaker connector now gently lift
the speaker by inserting your spudger
under the top edge of the speaker and
gently prying up while prying use your
tweezers or a spudger to peel away the
plastic bumper strip from the top edge
of the speaker and when you have the
speaker lifted slightly gently rock the
speaker up and out of the phone use the
pointy end of a spudger to disconnect
the taptic engine cable and then remove
the two Phillips screws securing the
engine in place now the taptic engine
should lift up and out the battery has a
total of four stretch adhesive strips
securing it to the case each of these
strips has a black pull tab that is
lightly adhered to the battery once you
have the tab separated from the battery
grab the pull tab with some blunt
tweezers and begin pulling and rolling
the strip so that it wraps over the
tweezers when pulling be mindful to
avoid making contact with any of the
surrounding hardware
if you do end up breaking an adhesive
strip head over to our guide at
ifixit.com we've got a complete
walkthrough with other options that'll
help you out be aware that when removing
the last adhesive strip the strip may
fling the battery out of the iPhone so
hold your hand over the battery to
prevent it from flying away now we're
ready to install our new battery first
things first we need to apply new
adhesive strips to start peel away the
blue plastic liner to expose the
adhesive position the strip so that the
black pull tabs overlap the edges of the
battery now press them into place
fold the black tab so that it sticks to
the battery and then remove the pink
liner to fully expose the adhesive make
sure the battery connector aligns with
the socket on the logic board and then
lay the new battery into your phone now
we can reassemble our iPhone first up
the taptic engine goes back in along
with the two screws that hold it in
place next you'll reconnect the taptic
engine cable reinsert the speaker then
reconnect its cable then reposition the
two brackets and reinsert the screws
holding them in place
now we need to reapply our display
adhesive this process can take a bit of
time but lucky for you we have an entire
video walking you through the process
we'll link to it down in the description
below
with your new adhesive strips applied
position your display along the side of
the iPhone and prop it up just like you
did during disassembly reconnect all the
cables and then realign the logic board
connector bracket make sure to use the
same screws and the same spots to avoid
damaging your phone then carefully align
the display along the top edge of the
phone and then press the top edge into
place once in place close the phone and
reinsert the pentalobe screws at the
bottom of the phone now that your iPhone
is completely reassembled it's time to
calibrate your battery to start fully
charge your battery to 100% and keep it
charging for at least another two hours
then use your iPhone until it shuts off
due to low battery
finally charge it uninterrupted back to
100% this will ensure that you get
optimal performance with your new
battery
