iPhone batteries are rated to hold 80% of their capacity for up to 500 charge cycles,
which lasts roughly 18-24 months for most users.
When that happens, you may notice performance issues with your phone, which means it’s
time for a new battery.
Today we are going to show you how to replace the battery in your iPhone 13!
For this repair you will need A P2 pentalobe driver, a Phillips #00 driver, a Y000 Driver,
An iOpener, a suction handle or iSclack, iFixit opening picks, tweezers , a spudger, and some
isopropyl alcohol.
We also recommend using a magnetic mat so you can keep track of screws, and write down
notes during your repair.
You will also need display adhesive to make your phone retains its water resistance when
you reseal your phone, as well as battery adhesive to make sure your battery isn’t
moving around after the replacement is finished.
Also make sure you are following the step by step guide on iFixit.com as you will be
able to read tips and tricks that will help you throughout the repair.
Before you start any iPhone repair, make sure you discharge your battery to below 25%.
A charged lithium-ion battery can catch fire or explode if you damage it.
Just a heads up before you replace your battery, Apple requires replacement parts to be synced
with the iPhone after replacement and unfortunately the software required to do this is not currently
available to the public.
After your battery replacement, your iPhone may display a warning about the “genuineness”
of the battery.
You’ll also notice battery health and performance reporting functions will no longer work, even
when using original Apple parts.
If your iPhone functions normally, you can safely ignore all these issues.
To begin, power off your phone by holding the side and bottom volume buttons.
Remove the two P2 pentalobe screws at the bottom edge of the iPhone.
Grab a hot iOpener and lay the clear side down along the bottom edge of the phone.
This will soften the display adhesive.
For the next few steps we are going to be using a iSclack.
If you don’t have a iSclack on hand refer to the repair guide on on our site where we
walk you through how to use a suction handle to remove the iPhone’s display.
Once your iPhone is heated, grab the iSclack and position its suction cups near the bottom
edge of the iphone.
Then press both cups firmly into place.
With the suction cups engaged, hold onto your phone securely and close the handles of the
iSclack to slightly separate the screen from the rear case.
For this step we’re not trying to fully separate the display from the phone’s body
we just want to create a gap.
Once you see a gap between the display and rear case insert a opening pick into the opening.
Next, place your heated iOpener on the left edge of the iphone for about a minute to soften
the adhesive.
Then slide the opening pick around the lower left corner and up the left edge of the iPhone,
making sure you don’t insert the pick more than 2mm.
Once you are done on the left side lay a heated iOpener on the ride edge of the iphone and
repeat this process.
Finally, place your iOpener along the top edge of the iPhone.
Insert your pick into the right edge at the top and slide it across the edge.
Be very careful and don’t insert the pick more than 1mm here.
With all the adhesive separated you can now open the phone by swinging the display up
from the right side like the front cover of a book.
Don’t try to fully remove the display yet though it is still attached via ribbon cables.
Lean the display against something like a box or your driver kit so that the iphone
is easier to work on, and then use a phillips screwdriver to remove the three screws securing
the battery and display connector cover.
Then remove the cover with your tweezers.
Use a spudger or clean fingernail and pry the battery connector up from its socket on
the logic board, and bend the connector away slightly so that you don’t risk the chance
of it making contact with the board.
Now disconnect the display cable connector from the logic board.
Remove the two phillips and one y000 screws securing the front sensor connector cover
and remove the cover with your tweezers by swinging the cover towards the display to
unclip the hook.
Now you can disconnect the front sensor assembly cable from the logic board-and your display
is now free from the rear case.
To have easier access to the adhesive pull tabs securing the battery we need to remove
the loudspeaker, it’s held in place by four phillips screws.
When those screws are out you can remove the loudspeaker.
There are 4 adhesive strips with pull tabs holding that battery in place.
To remove them begin by gently lifting up the edges of the pull tabs and then use a
pair of blunt tweezers to peel the tabs away from the battery.
Starting with the bottom strips, grab a tab with your fingers and slowly pull it away
from the battery while holding the sides of the phone.
Pull until the strip pops out and then repeat the process for the pull tab next to it.
If a pull tab breaks or you are having trouble removing the strips, grab some isopropyl alcohol
and apply some around the battery.
Tilt the phone so the alcohol penetrates under the battery and then let it sit for a couple
of minutes.
Once that’s done the battery should lift out with just a little force.
Check to see if your replacement battery came with preinstalled adhesive strips.
If there are no strips in place check out our video on how to install adhesive strips
on your battery.
Lay the battery in your phone gently and position it so that your are able to connect the battery
to the logic board.
Once it’s in place press down on the battery to activate the adhesive, and then disconnect
the battery using a spudger or your fingernail, we don’t want the phone to be powered during
the rest of this repair.
Insert the loudspeaker and reinstall the screws securing it to the phone.
Make sure your display has its adhesive strips in place, if it doesn’t check out our video
walking you through the process of reinstalling display adhesive.
This will ensure that your phone retains its water resistance.
With the backing of the adhesive still in place-align the display with your phone and
connect the front sensor cable and display cable to the logic board.
Go ahead and connect the battery cable and power on your phone to make sure it functions
properly.
If all is well, power your phone off and screw the covers over the battery and display cables
back into place.
If your adhesive backing is still on go ahead and remove it.
Now lay the display into position by aligning the clips along the top edge and carefully
pressing the top edge into place.
If it doesn’t click easily into place check the clips to make sure they aren’t bent.
If they do click into place easily, continue pressing the rest of the display down.
Finally screw back in the two pentalobe screws at the bottom of the phone.
For best battery results we recommend calibrating your new battery.
