Guide overview

Before you begin

Use this guide to replace the battery in your iPhone 15 Pro. iPhone batteries are rated to hold 80% of their capacity for up to 1000 charge cycles. If your iPhone needs to be charged more often or runs slower, it might be time to replace the battery. You'll need replacement screen adhesive to complete this repair. If your new battery doesn't come with adhesive pre-installed, you'll need replacement adhesive for it as well. If your battery is swollen, take appropriate precautions. Note: Due to Apple's parts pairing restrictions, on iOS 17.6 and earlier, you may receive warnings about your replacement part and lose access to battery health data, but your new battery will otherwise work normally. On iOS 18 and newer, all batteries should work normally. Pair original Apple batteries using Repair Assistant.

Step 1

Prepare your iPhone for disassembly

  • Let your phone's battery drain below 25% before starting this repair—a charged lithium‑ion battery may catch fire if damaged.
  • Unplug all cables from your phone.
  • Hold the power and either volume button and slide to power off your phone.
Step 2

Tape over any cracks

  • If your screen or back glass is cracked, lay overlapping strips of packing tape over the glass to protect yourself and make disassembly easier.
  • Make sure there's a smooth area near the bottom edge that's big enough for a suction cup to stick to.
Step 3

Mark your opening picks

  • If inserted too far, an opening pick can damage your device. Follow this step to mark your pick and prevent damage.
  • Measure 3 mm from the tip and mark the opening pick with a permanent marker.
  • You can also mark the other corners of the pick with different measurements.
  • Alternatively, tape a coin to a pick 3 mm from the tip.
Step 4

Remove the pentalobe screws

  • Use a P2 pentalobe screwdriver to remove the two 7 mm‑long screws on either side of the charging port.
Step 5

Heat the bottom edge

  • Use a hair dryer or heat gun to heat the bottom edge of the screen until it's hot to the touch.
  • Be careful not to heat the phone hotter than this—the battery is susceptible to heat damage.
Step 6

Insert an opening pick

  • Apply a suction handle to the bottom edge of the screen.
  • Pull up on the handle with a strong, steady force to create a gap between the screen and the frame.
  • Insert the tip of an opening pick into the gap.
Step 7

Screen information

  • As you slice the adhesive securing the screen in the next steps, be careful of the following areas:
  • There are two delicate cables connecting the screen to the phone: one just above the action button, and the other near the middle of the left edge.
  • There are multiple spring contacts around the perimeter of the phone. Be extra careful not to insert your pick deeper than suggested in these locations to avoid bending the contacts.
Step 8

Separate the bottom edge adhesive

  • Don't insert your opening pick deeper than 3 mm along the bottom edge.
  • Slide your pick back and forth along the bottom edge to separate the adhesive.
  • Leave your pick inserted in the bottom right corner to prevent the adhesive from re-sealing.
Step 9

Heat the right edge

  • Heat the right edge of the screen until it's hot to the touch.
Step 10

Position the opening pick

  • Don't insert your pick deeper than 5 mm along the right edge.
  • Slide your pick around the bottom right corner of the screen and toward the power button until you feel a hard stop at a clip securing the screen.
  • Rotate your pick so the flat edge is under the screen.
Step 11

Release the right clip

  • Twist the pick to increase the gap between the screen and the frame until the right clip releases.
  • Insert a second opening pick to the right of the first pick.
Step 12

Separate the right edge adhesive

  • Slide the first pick back to the bottom right corner of the screen.
  • Slide the second pick to the top right corner of the screen to separate the adhesive.
  • Leave these picks inserted to prevent the adhesive from resealing.
Step 13

Heat the top edge

  • Heat the top edge of the screen until it's hot to the touch.
Step 14

Separate the top edge adhesive

  • Don't insert your pick deeper than 3 mm along the top edge.
  • Slide your pick around the top right corner and along the top edge to release the two clips and adhesive securing it.
Step 15

Heat the left edge

  • Heat the left edge of the screen until it's hot to the touch.
Step 16

Separate the left edge adhesive

  • Don't insert your pick deeper than 2 mm along the left edge to avoid the two cables connecting the screen to the phone.
  • Rotate your pick around the top left corner of the screen.
  • Slide your pick to the bottom left corner of the screen to separate the adhesive.
Step 17

Prop up the screen

  • Place a small box or stack of books to the left of your phone so you can prop up the screen while disconnecting its cables.
  • Swing up the right edge of the screen like the front cover of a book.
  • If the screen feels stuck, go back around the perimeter with an opening pick to separate any remaining adhesive.
  • Prop up the screen so you can access its cables without straining them.
Step 18

Unfasten the logic board cover

  • Use a Y000 screwdriver to remove the six screws securing the logic board cover:
  • Four 1.6 mm‑long screws
  • Two 1.3 mm‑long screws
Step 19

Remove the logic board cover

  • Rotate the bottom of the logic board cover counterclockwise and slide the top left corner out from under the ambient light sensor cable to remove it.
  • During reassembly, make sure the top left corner of the cover goes under the ambient light sensor cable.
Step 20

Disconnect the battery

  • Use the tip of an opening pick to pry up and disconnect the battery press connector from the bottom right corner of the logic board.
  • To reconnect a press connector, align it over its socket and gently press down on one side until it clicks into place, then press down on the other side. Make sure it sits flat, as the insulating rubber around the sockets might prevent it from connecting fully.
Step 21

Disconnect the screen

  • Use the tip of an opening pick to pry up and disconnect the screen cable from the center of the logic board.
Step 22

Disconnect the ambient light sensor

  • Gently slide the tip of an opening pick under the ambient light sensor cable near the top left corner of the logic board.
  • Lift the cable to disconnect it.
Step 23

Remove the screen

  • Remove the screen.
  • During reassembly, follow this guide to apply new adhesive and install your screen.
  • Be careful not to damage any of the spring contacts as you clean the frame.
Step 24

Unfasten the loudspeaker

  • Use a Phillips #000 screwdriver to remove the four screws securing the loudspeaker:
  • One 2.7 mm‑long screw
  • Three 2 mm‑long screws
Step 25

Remove the loudspeaker

  • A plastic buffer is adhered to the top edges of the loudspeaker and Taptic Engine.
  • Lift the bottom edge of the loudspeaker until you can grab it with your fingers.
  • Peel the loudspeaker from the plastic buffer on its top edge and remove it.
Step 26

Disconnect the Taptic Engine

  • Use a Phillips #000 screwdriver to remove the two 2 mm‑long screws securing the Taptic Engine.
Step 28

Remove the Taptic Engine

  • Remove the Taptic Engine.
Step 29

Adhesive information

  • Three sections of stretch release adhesive secure the battery to the frame—two along the bottom and one on top.
  • Each strip has a black pull tab at its end, which is lightly adhered to the edge of the battery.
  • In the following steps, you'll pull each tab out from underneath the battery.
  • The strips loosen when stretched, but might break off before you can fully remove them, especially the top edge strip. If any break, don't worry! Keep reading for an alternate way to remove the battery.
Step 30

Separate the pull tabs

  • Don't puncture or dent the battery with your tool, as it can leak dangerous chemicals or catch fire if damaged.
  • Use the tip of an opening pick to gently unstick an edge of an adhesive pull tab from the edge of the battery.
  • Use blunt nose tweezers to grip the edge of the pull tab and pull it completely off the edge of the battery.
  • Repeat for the other two pull tabs.
Step 31

Remove the stretch release adhesive

  • Pull one of the pull tabs out from under the battery until you can grip it with your fingers or wrap it around your tool.
  • Hold the phone steady using the edges of the frame—don't press down on the battery.
  • Pull the strip slowly, evenly, and at a low angle without dragging on other components.
  • Continue pulling, re-gripping or wrapping it around your tool as you go, until the strip fully releases from under the battery.
  • If the strip breaks off, try to retrieve it. If you can't grip it from under the battery, move on to the next step.
  • Repeat this step for the other two strips.
Step 32

Alternate method to remove the battery

  • If you removed all three stretch release adhesive strips, congratulations—you can now remove the battery! If not, follow the next two steps to separate the adhesive with isopropyl alcohol and a plastic card.
  • If the top strip remains, prop up the top edge of the phone.
  • If either of the bottom strips remain, prop up the left edge of the phone (the side with the volume buttons).
  • Use a pipette or syringe to apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to the elevated edge of the battery.
  • Wait one minute for the isopropyl alcohol to flow under the battery and soften the adhesive.
Step 33

Pry up the battery

  • Don't bend or crease your battery. If the adhesive feels stubborn, apply a few more drops of isopropyl alcohol and try again.
  • Insert the short edge of a plastic card between the bottom edge of the battery and the frame.
  • Be careful not to scrape the frame underneath the battery—the wireless charging coil is exposed near the center.
  • Gently pry up the battery until the adhesive fully separates.
  • Depending on how strong your adhesive is, this may take some time. Allow up to a minute of constant pressure for the adhesive to loosen.
Step 34

Remove the battery

  • Remove the battery.
Step 35

Disassembly complete

  • Congratulations on completing disassembly! The remaining steps show how to reassemble the iPhone.
Step 36

Clean the frame

  • Use cotton swabs or a lint‑free cloth and high‑concentration (>90%) isopropyl alcohol to wipe off any battery adhesive residue from the iPhone's frame.
Step 37

Remove the adhesive liner

  • Peel the liner off the battery adhesive, pictured here in pink.
  • If the battery has a liner on the top of the battery, pictured here in blue, leave it in place for now.
Step 38

Connect the battery

  • Hold the battery over its place in the iPhone, but don't lower it into place yet.
  • Use your finger or a spudger to connect the battery press connector.
  • This will ensure the battery is properly aligned.
Step 39

Place the battery

  • The battery adhesive is very sticky! Be careful as you align the battery in its recess—once it sticks, you won't be able to realign it.
  • Push the battery towards the top of the iPhone so the battery cable is pressed against it, then lay it into its recess.
Step 40

Press the battery

  • Use your fingers to press the battery into place.
Step 41

Remove the battery liner

  • Remove the protective cover off the top of the battery (if present).
Step 42

  • One 2.7 mm‑long screw
  • Three 2 mm‑long screws
Step 48

Remove the screen adhesive

  • The adhesive remaining on the phone is difficult to remove and leaves residue. If you have trouble removing the adhesive, apply some heat using a hair dryer or heat gun.
  • Use a spudger to push the screen adhesive up until you can grab it with a pair of tweezers.
  • Use a pair of tweezers, or your fingers, to remove the adhesive around the entire perimeter of the iPhone.
Step 49

Repair step

  • Any unevenness will compromise the iPhone's seal. Clean the frame thoroughly.
  • Apply a few drops of high-concentration (greater than 90%) isopropyl alcohol to a cotton swab or lint-free cloth.
  • Wipe along the perimeter of the frame to clean the adhesive residue.
  • Wait a few minutes before proceeding to make sure any excess alcohol has evaporated.
Step 50

Orient the adhesive

  • Lay the adhesive next to the phone and use features like cutouts for spring contacts and the front‑facing camera to orient it correctly.
Step 51

Apply the adhesive

  • Once the adhesive is pressed into place, you can't reposition it—you'll have to remove it and start over with new adhesive.
  • Use the pull tab to begin peeling the back liner off of the adhesive starting from the bottom, but don't remove it all the way.
  • While holding the back liner out of the way, carefully align the exposed edge of the adhesive to the bottom edge of the iPhone's frame.
  • When the adhesive is aligned, set it down along the bottom edge.
Step 52

Repair step

  • Continue peeling the back liner off of the adhesive while setting the adhesive into place along the edges of the iPhone's frame.
  • If you correctly aligned the lower edge of the adhesive, the side and top edges will fall perfectly into place. If the adhesive is misaligned, remove it and start over with new adhesive.
  • If you don't have another one handy, it's okay to put your iPhone back together without adhesive, but keep in mind that it won't be water resistant until you install new adhesive.
Step 53

Press the adhesive into place

  • Use the flat end of a spudger to press the adhesive into place all around the iPhone.
  • Be careful not to press on the camera, spring contacts, or other internal components.
Step 54

Remove the top liner

  • Lift the pull tab in the top‑right corner of the frame to peel off the top liner and remove it.
  • Your pull tab may be in a different location. Make sure you're pulling the full-size top liner, not the thin liners along the edges.
Step 55

Adhesive information

  • Once the top liner is removed, there should be three narrow liners on top of the adhesive with pull tabs near the bottom edge.
  • Your pull tabs may be in different positions.
  • If you don't see these pull tabs, you may have accidentally removed the thin liners in the previous step. Be careful not to touch anything to the exposed adhesive.
Step 56

Prop up the screen

  • Prop the screen up along the left edge of the iPhone frame, using a box or similar sturdy object to support the screen.
Step 57

Connect the screen and ambient light sensor

  • Use your finger or the flat end of a spudger to connect the screen and ambient light sensor press connectors.
Step 58

Connect the battery

  • Use your finger or the flat end of a spudger to connect the battery press connector.
Step 59

Install the logic board cover

  • Slide the top left corner of the logic board cover under the ambient light sensor cable and set it into place, aligned with its screw holes.
Step 60

Fasten the logic board cover

  • Use a Y000 screwdriver to install the six screws securing the logic board cover:
  • Four 1.6 mm‑long screws
  • Two 1.3 mm‑long screws
Step 61

Remove the final adhesive liners

  • Once you remove the liners in this step, the adhesive will be fully exposed. Make sure nothing accidentally sticks to it.
  • Use tweezers to remove the two narrow liners covering the adhesive along the right, top, and bottom edges of the frame.
Step 62

Repair step

  • Without letting the screen touch the adhesive, hold the screen over the phone so you can access the final liner along the left edge of the frame.
  • Use a pair of tweezers or your fingers to remove the final liner along the left edge of the frame.
Step 63

Place the screen

  • Align the screen over the frame, then lower it into place.
Step 64

  • Firmly press along the edges of the screen to engage the clips and compress the adhesive.
Step 65

Install the pentalobe screws

  • Use a P2 pentalobe screwdriver to install the two 7 mm‑long screws on either side of the charging port.
Step 66

Heat the screen

  • To help the adhesive bond, apply heat to the edges of the screen using a hair dryer or heat gun until it's hot to the touch.
  • If you have screen vise clamps, use them to strengthen the bond of the new adhesive. If not, keep reading for more ways to secure the screen.
Step 67

Press the back glass

  • To evenly compress the iPhone and strengthen the bond of the screen to the frame, you need to account for the camera bump.
  • If you have the iPhone's original box, take the lid and place it on a flat surface.
  • If you don't have the original box, skip this step for an alternate method.
  • Place the iPhone screen-side-up in the lid of the box with the camera bump in its recess.
  • Find something close to the size of the iPhone, but taller than the sides of the box. Stack it on top of the iPhone, followed by a few heavy objects.
  • Leave the objects in place for at least thirty minutes, ideally overnight.
Step 68

Repair step

  • If you don't have the iPhone's original box, follow the these two steps for another method to evenly compress the screen.
  • Place the iPhone screen-side-down on a soft, flat surface.
  • Apply tape to the back glass to protect its finish.
  • Place three layers of coins or similarly thick objects on the tape along the edges of the back glass.
  • Evenly distribute the coins and make sure they are at least as thick as the camera bump.
Step 69

Repair step

  • Stack multiple books or other heavy objects on your iPhone.
  • The coins may leave an impression on the bottom object, so don't use anything valuable.
  • Leave the objects in place for at least thirty minutes, ideally overnight.
