  1. iPhone 12 mini Battery Replacement, Remove the pentalobe screws: step 1, image 1 of 2 iPhone 12 mini Battery Replacement, Remove the pentalobe screws: step 1, image 2 of 2
    • 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 6.7 mm-long pentalobe screws at the bottom edge of the iPhone.

  2. iPhone 12 mini Battery Replacement, Heat the bottom edge of the phone: step 2, image 1 of 1
    • 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.

    • Heating the bottom 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 two minutes in order to soften up the adhesive underneath.

    • If you have trouble during the opening procedure the adhesive most likely cooled down. Apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

  3. iPhone 12 mini Battery Replacement, Apply suction cup(s): step 3, image 1 of 2 iPhone 12 mini Battery Replacement, Apply suction cup(s): step 3, image 2 of 2
    • 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.

    • 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.

    • 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 12 mini Battery Replacement, Apply a suction handle: step 5, image 1 of 2 iPhone 12 mini Battery Replacement, Apply a suction handle: step 5, image 2 of 2
    • If you're using a single suction handle, apply it to the bottom edge of the phone, as close to the edge as possible.

    • 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 12 mini Battery Replacement, Lift the display slightly: step 6, image 1 of 3 iPhone 12 mini Battery Replacement, Lift the display slightly: step 6, image 2 of 3 iPhone 12 mini Battery Replacement, Lift the display slightly: step 6, 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 tool.

    • Slide the opening pick around the bottom right corner and along the right edge of the iPhone, slicing through the adhesive holding the display in place.

    • Don't insert the opening pick too far underneath the front panel, or you may cause damage to internal components.

  8. iPhone 12 mini Battery Replacement: step 8, image 1 of 3 iPhone 12 mini Battery Replacement: step 8, image 2 of 3 iPhone 12 mini Battery Replacement: step 8, image 3 of 3
    • Re-insert your pick at the bottom left corner of the iPhone.

    • Slide the opening pick around the bottom left corner and along the left edge of the iPhone, slicing through the adhesive holding the display in place.

    • Don't insert the pick very far, or you may damage the display cables along this side of the iPhone. Insert it only a few millimeters, or about the width of the display bezel.

  9. iPhone 12 mini Battery Replacement: step 9, image 1 of 3 iPhone 12 mini Battery Replacement: step 9, image 2 of 3 iPhone 12 mini Battery Replacement: step 9, image 3 of 3
    • The top edge of the display is secured with both glue and clips.

    • Again, don't insert the pick more than a few millimeters—about the width of the display bezel—or you may damage the front panel sensor array.

    • Insert your pick underneath the top-right corner of the display panel.

    • Slide the pick around the top right corner. Because of the clips you might encounter some resistance.

    • Gently pulling the front panel assembly towards the bottom edge of the phone simplifies this step a little.

    • Slide the pick along the top edge and cut any remaining adhesive securing the display.

  10. iPhone 12 mini Battery Replacement, Remove the suction cup(s): step 10, image 1 of 1
    • Pull on the small nub on the suction cup to remove it from the front panel.

    • If you used an iSclack and it's still affixed to the iPhone, remove it now.

  11. iPhone 12 mini Battery Replacement, Open the iPhone: step 11, image 1 of 3 iPhone 12 mini Battery Replacement, Open the iPhone: step 11, image 2 of 3 iPhone 12 mini Battery Replacement, Open the iPhone: step 11, image 3 of 3
    • 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.

    • Remove the 1.25 mm-long Y000 screw securing the battery & display connector cover bracket.

    • 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.

  12. iPhone 12 mini Battery Replacement, Remove the battery and display connector cover: step 13, image 1 of 2 iPhone 12 mini Battery Replacement, Remove the battery and display connector cover: step 13, image 2 of 2
    • Use a pair of tweezers to remove the battery & display connector bracket.

    • There are two little hinges on the right edge of the connector bracket. Make sure to align them with their counterparts during reassembly.

  13. iPhone 12 mini Battery Replacement, Disconnect the battery: step 14, image 1 of 2 iPhone 12 mini Battery Replacement, Disconnect the battery: step 14, 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.

  14. iPhone 12 mini Battery Replacement, Disconnect the OLED display cable: step 15, image 1 of 2 iPhone 12 mini Battery Replacement, Disconnect the OLED display cable: step 15, image 2 of 2
    • Use a spudger or a clean fingernail to pry the OLED panel cable connector up from its socket on the logic board.

    • 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.

  15. iPhone 12 mini Battery Replacement, Unscrew the front sensor assembly cover: step 16, image 1 of 2 iPhone 12 mini Battery Replacement, Unscrew the front sensor assembly cover: step 16, image 2 of 2
    • Remove the five 1 mm-long Y000 screws securing the front sensor assembly cover bracket.

  16. iPhone 12 mini Battery Replacement: step 17, image 1 of 2 iPhone 12 mini Battery Replacement: step 17, image 2 of 2
    • Use a pair of tweezers to remove the front sensor assembly bracket.

  17. iPhone 12 mini Battery Replacement, Disconnect the front sensors: step 18, image 1 of 2 iPhone 12 mini Battery Replacement, Disconnect the front sensors: step 18, image 2 of 2
    • Use a spudger or a clean fingernail to disconnect the front sensor assembly cable connector.

  19. iPhone 12 mini Battery Replacement, Unscrew the speaker: step 20, image 1 of 2 iPhone 12 mini Battery Replacement, Unscrew the speaker: step 20, image 2 of 2
    • Remove the four 1.5 mm-long Phillips #000 screws securing the speaker.

  20. iPhone 12 mini Battery Replacement, Remove the speaker: step 21, image 1 of 2 iPhone 12 mini Battery Replacement, Remove the speaker: step 21, image 2 of 2
    • Use a pair of tweezers to remove the speaker.

  21. iPhone 12 mini Battery Replacement, Remove the adhesive strips: step 22, image 1 of 2 iPhone 12 mini Battery Replacement, Remove the adhesive strips: step 22, image 2 of 2
    • Peel down the first battery adhesive pull-tab to un-stick it from the bottom edge of the battery.

    • Don't jab the battery with any sharp tools. A punctured battery may leak dangerous chemicals or catch fire.

  22. iPhone 12 mini Battery Replacement: step 23, image 1 of 3 iPhone 12 mini Battery Replacement: step 23, image 2 of 3 iPhone 12 mini Battery Replacement: step 23, image 3 of 3
    • Grab the 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.

  23. iPhone 12 mini Battery Replacement: step 24, image 1 of 2 iPhone 12 mini Battery Replacement: step 24, image 2 of 2
    • Grab the wide pull tab with your fingers and slowly pull it away from the battery, toward the bottom of the iPhone.

  24. iPhone 12 mini Battery Replacement: step 25, image 1 of 3 iPhone 12 mini Battery Replacement: step 25, image 2 of 3 iPhone 12 mini Battery Replacement: step 25, image 3 of 3
    • Grab the pull tab with your fingers and slowly pull it away from the battery, toward the bottom of the iPhone.

    • Repeat the previous procedure on the two remaining pull tabs.

    • If the adhesive breaks off underneath the battery and can't be retrieved, apply a few drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery in the area of the broken adhesive strip(s).

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

    • Use 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.

  25. iPhone 12 mini Battery Replacement, Remove the battery.: step 26, image 1 of 2 iPhone 12 mini Battery Replacement, Remove the battery.: step 26, image 2 of 2
    • Remove the battery.

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

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

Заключение

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

To reassemble your device, follow the above steps in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

For optimal performance, after completing this guide, calibrate your newly installed battery.

Take your e-waste to an R2 or e-Stewards certified recycler.

If you replace the battery (even with a first party one) you will need to go to Apple, unfortunately, as is for the new iPhone 13 models.

I don't think it's stated clearly enough that the display adhesive is VERY strong and you might think you've gotton a big enough gap when sticking in a pick will actually separate the layers of the screen and break it (defintely not speaking from experience). Make sure the phone is totally, thoroughly heated and be very, very careful.
