What you need

  1. iPhone 13 Battery Replacement, Remove the pentalobe screws: step 1, image 1 of 1
    • Caution: Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 6.8 mm-long pentalobe P2 screws at the bottom edge of the iPhone.

    • Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

  2. iPhone 13 Battery Replacement, Tape over any cracks: step 2, image 1 of 3 iPhone 13 Battery Replacement, Tape over any cracks: step 2, image 2 of 3 iPhone 13 Battery Replacement, Tape over any cracks: step 2, image 3 of 3
    • If your iPhone has a cracked screen, keep further breakage contained and prevent bodily harm during your repair by taping over the glass.

    • Lay overlapping strips of packing tape over the iPhone's display until the whole face is covered.

    • This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • Wear safety glasses to protect your eyes from any glass shaken free during the repair.

    • If the broken glass makes it difficult to get a suction cup to stick in the next few steps, try folding a strong piece of tape (such as duct tape) into a handle and lifting the display with that instead.

  3. iPhone 13 Battery Replacement, Heat the lower edge of the iPhone: step 3, image 1 of 1
    • Heating the lower edge of the iPhone helps soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or heat gun or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.

    • The next two steps demonstrate the iSclack, a handy tool that we recommend for anyone doing frequent repairs. If you aren't using the iSclack, skip down two steps for an alternate method.

    • If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger iPhones like the iPhone 13.

    • Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.

    • Press both suction cups firmly into place.

    • If your display or back glass is badly cracked, covering it with a layer of clear packing tape may help the suction cups adhere. The iSclack also includes two pieces of tape for this purpose.

  4. iPhone 13 Battery Replacement, Lift the display slightly: step 5, image 1 of 3 iPhone 13 Battery Replacement, Lift the display slightly: step 5, image 2 of 3 iPhone 13 Battery Replacement, Lift the display slightly: step 5, image 3 of 3
    • Hold onto your iPhone securely and close the handle of the iSclack to slightly separate the screen from the rear case of the phone.

    • Don't try to completely separate the screen; a small opening along the bottom edge is all you need.

    • Insert an opening pick into the gap under the display on the lower edge of the iPhone.

    • Skip the next two steps.

  5. iPhone 13 Battery Replacement, Apply a suction cup: step 6, image 1 of 2 iPhone 13 Battery Replacement, Apply a suction cup: step 6, image 2 of 2
    • If you're using a single suction handle, apply it to the bottom edge of the phone, while avoiding the very edge of the glass.

    • If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

  6. iPhone 13 Battery Replacement, Lift the display slightly: step 7, image 1 of 3 iPhone 13 Battery Replacement, Lift the display slightly: step 7, image 2 of 3 iPhone 13 Battery Replacement, Lift the display slightly: step 7, image 3 of 3
    • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.

    • Insert an opening pick into the gap.

    • The watertight adhesive holding the display in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your opening pick.

  7. iPhone 13 Battery Replacement, Separate the screen adhesive: step 8, image 1 of 1
    • Heating the edges of the iPhone will make it easier to cut through the adhesive securing the display.

    • Apply heat to the left edge of the iPhone for about one minute to soften the adhesive underneath.

  8. iPhone 13 Battery Replacement: step 9, image 1 of 3 iPhone 13 Battery Replacement: step 9, image 2 of 3 iPhone 13 Battery Replacement: step 9, image 3 of 3
    • Slide the opening pick around the lower left corner and up the left edge of the iPhone, slicing through the adhesive holding the display in place.

    • Don't insert the pick more than 2 mm or you may damage the display cables along this side of the iPhone.

  9. iPhone 13 Battery Replacement: step 10, image 1 of 1
    • Apply heat to the right edge of the iPhone for about one minute to soften the adhesive underneath.

  10. iPhone 13 Battery Replacement: step 11, image 1 of 3 iPhone 13 Battery Replacement: step 11, image 2 of 3 iPhone 13 Battery Replacement: step 11, image 3 of 3
    • Re-insert your pick at the bottom edge of the iPhone, and slide it up the right side to continue separating the adhesive.

    • Don't insert the pick more than 2 mm or you may damage internal components.

  11. iPhone 13 Battery Replacement: step 12, image 1 of 1
    • Apply heat to the top edge of the iPhone for about one minute to soften the adhesive underneath.

  12. iPhone 13 Battery Replacement: step 13, image 1 of 3 iPhone 13 Battery Replacement: step 13, image 2 of 3 iPhone 13 Battery Replacement: step 13, image 3 of 3
    • The top edge of the display is secured with both glue and clips.

    • Insert your pick into the right edge of the phone. Slide it around the top-right corner and across the top edge.

    • Don't insert the pick more than 1 mm or you may damage the front panel sensor array.

  13. iPhone 13 Battery Replacement, Open the iPhone: step 14, image 1 of 3 iPhone 13 Battery Replacement, Open the iPhone: step 14, image 2 of 3 iPhone 13 Battery Replacement, Open the iPhone: step 14, image 3 of 3
    • If you haven't removed your suction handle or iSclack, remove it now.

    • Open the iPhone by swinging the display up from the right side, like the front cover of a book.

    • Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.

    • Lean the display against something to keep it propped up while you're working on the phone.

    • During reassembly, lay the display in position, align the clips along the top edge, and carefully press the top edge into place before snapping the rest of the display down. If it doesn't click easily into place, check the condition of the clips around the perimeter of the display and make sure they aren't bent.

    • Use a Phillips screwdriver to remove the three 1.3 mm screws securing the battery and display connector cover.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.

    • During reassembly, this is a good point to power on your iPhone and test all functions before you seal the display in place. Be sure to power your iPhone back down completely before you continue working.

  14. iPhone 13 Battery Replacement, Remove the battery and display connector cover: step 16, image 1 of 1
    • Remove the cover.

  15. iPhone 13 Battery Replacement, Disconnect the battery: step 17, image 1 of 2 iPhone 13 Battery Replacement, Disconnect the battery: step 17, image 2 of 2
    • Use a spudger or a clean fingernail to pry the battery connector up from its socket on the logic board.

    • Try not to damage the black silicone seal surrounding this and other board connections. These seals provide extra protection against water and dust intrusion.

    • Bend the connector slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

  16. iPhone 13 Battery Replacement, Disconnect the display cable: step 18, image 1 of 2 iPhone 13 Battery Replacement, Disconnect the display cable: step 18, image 2 of 2
    • Use a spudger or a fingernail to disconnect the display cable connector.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

  17. iPhone 13 Battery Replacement, Unscrew the front sensor connector cover: step 19, image 1 of 1
    • Remove three screws securing the front sensor connector cover:

    • One 1.7 mm Phillips screw

    • One 1.3 mm Phillips screw

    • One 1.8 mm Y000 screw

  18. iPhone 13 Battery Replacement, Remove the front sensor connector cover: step 20, image 1 of 2 iPhone 13 Battery Replacement, Remove the front sensor connector cover: step 20, image 2 of 2
    • Swing the cover up from the center of the phone until the small clip by the edge of the phone unhooks.

  19. iPhone 13 Battery Replacement: step 21, image 1 of 2 iPhone 13 Battery Replacement: step 21, image 2 of 2
    • Remove the cover.

    • During reassembly, insert the clip on the left edge into its slot first, then hinge the rest of the cover into place.

  20. iPhone 13 Battery Replacement, Disconnect the front sensors: step 22, image 1 of 2 iPhone 13 Battery Replacement, Disconnect the front sensors: step 22, image 2 of 2
    • Use a spudger or a fingernail to disconnect the front sensor assembly cable connector.

  24. iPhone 13 Battery Replacement, Locate the adhesive pull-tabs: step 26, image 1 of 3 iPhone 13 Battery Replacement, Locate the adhesive pull-tabs: step 26, image 2 of 3 iPhone 13 Battery Replacement, Locate the adhesive pull-tabs: step 26, image 3 of 3
    • The battery is secured to the rear case with four pieces of stretch-release adhesive—two on the bottom edge of the battery, and two on the top edge.

    • Each piece of adhesive has a black pull-tab at the end, which is lightly adhered to the edge of the battery.

    • In the following steps, you'll pull each tab to slowly stretch out the adhesive underneath the battery. These "command-strip" style adhesives lose their stick when stretched, so you can remove the battery with ease.

    • If the strips break, don't panic! They don't always work as intended. Keep reading for tips on removing broken strips.

  25. iPhone 13 Battery Replacement, Remove the stretch-release adhesive: step 27, image 1 of 3 iPhone 13 Battery Replacement, Remove the stretch-release adhesive: step 27, image 2 of 3 iPhone 13 Battery Replacement, Remove the stretch-release adhesive: step 27, image 3 of 3
    • Caution: Don't jab the battery with any sharp tools. A punctured battery may leak dangerous chemicals or catch fire.

    • Use the flat end of a spudger to gently lift up the edge of the top right battery adhesive pull-tab so that you can grab it with a pair of blunt tweezers.

    • Peel down the battery adhesive pull-tab to un-stick it from the top edge of the battery.

    • Repeat for the top left battery adhesive pull-tab.

  26. iPhone 13 Battery Replacement: step 28, image 1 of 3 iPhone 13 Battery Replacement: step 28, image 2 of 3 iPhone 13 Battery Replacement: step 28, image 3 of 3
    • Peel up the two remaining battery adhesive pull-tabs to un-stick them from the bottom edge of the battery.

  27. iPhone 13 Battery Replacement: step 29, image 1 of 1
    • Optionally, tilt the bottom of the phone up and apply a few drops of high-concentration (90% or higher) isopropyl alcohol to the bottom edge of the battery, and wait a minute. It'll help soften the adhesives, especially if the phone is old.

  28. iPhone 13 Battery Replacement: step 30, image 1 of 3 iPhone 13 Battery Replacement: step 30, image 2 of 3 iPhone 13 Battery Replacement: step 30, image 3 of 3
    • Grab the bottom right pull-tab with your fingers and slowly pull it away from the battery, toward the bottom of the iPhone.

    • Pull hard enough to maintain tension on the strip, but don't force it. Give it plenty of time to stretch and un-stick from under the battery.

    • Don't press down on the battery. Hold the iPhone firmly by its sides.

    • Keep the strip flat and unwrinkled. Try to pull evenly on the whole strip, rather than pulling mainly in the middle or on one side.

    • Pull at a low angle so the strip doesn't snag on the edge of the battery.

    • If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.

    • If any of the adhesive strips break off underneath the battery and can't be retrieved, try to remove the other strips, and then proceed as instructed below.

  29. iPhone 13 Battery Replacement: step 31, image 1 of 3 iPhone 13 Battery Replacement: step 31, image 2 of 3 iPhone 13 Battery Replacement: step 31, image 3 of 3
    • Grab the bottom left pull-tab with your fingers and pull it away from the battery, toward the bottom of the iPhone.

    • Follow the same procedure as with the previous strip: don't press down on the battery, keep the strip flat and unwrinkled, and pull at a low angle.

    • If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.

    • If the adhesive breaks off underneath the battery and can't be retrieved, continue with the next step.

  30. iPhone 13 Battery Replacement: step 32, image 1 of 3 iPhone 13 Battery Replacement: step 32, image 2 of 3 iPhone 13 Battery Replacement: step 32, image 3 of 3
    • You can optionally wrap the pull-tabs around the tips of blunt tweezers to make it easier to pull out the adhesive strip:

    • Use a pair of blunt tweezers to grab the entire width of the pull-tab.

    • Wrap the pull-tab and adhesive strip around the tips of the blunt tweezers.

    • Using the same procedure as before, pull the top right pull-tab to stretch and remove the adhesive strip. Try not to snag the adhesive on anything.

    • If you're still having trouble removing the battery, apply a few drops of high concentration (90% or higher) isopropyl alcohol under the edge of the battery in the area of the broken adhesive strip(s).

    • Tilt the phone up so the isopropyl alcohol can flow toward the adhesive strip.

    • Wait about one minute for the alcohol solution to weaken the adhesive.

    • Use an opening pick or the flat end of a spudger to gently lift the battery.

    • Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

  33. iPhone 13 Battery Replacement, Remove the battery: step 35, image 1 of 2 iPhone 13 Battery Replacement, Remove the battery: step 35, image 2 of 2
    • Remove the battery from the iPhone.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off with a coffee filter or allow it to air dry before installing your new battery.

    • If your new battery didn't come with adhesive preinstalled, refer to this guide for help replacing the adhesive strips.

    • Perform a force restart after reassembly. This can prevent several issues and simplify troubleshooting.
