    • Press firmly to eject the tray.

  2. iPhone 12 Battery Replacement, Remove the SIM card tray: 2 단계, 이미지 1/3 iPhone 12 Battery Replacement, Remove the SIM card tray: 2 단계, 이미지 2/3 iPhone 12 Battery Replacement, Remove the SIM card tray: 2 단계, 이미지 3/3
    • Remove the SIM card tray from the iPhone.

    • The SIM card will fall out of the tray easily.

    • When reinserting the SIM card, make sure it's in the proper orientation inside the tray.

    • A thin rubber gasket around the SIM tray provides water and dust protection. If this gasket is damaged or missing, replace the gasket or the entire SIM tray to protect your iPhone's internal components.

  3. iPhone 12 Battery Replacement, Remove the pentalobe screws: 3 단계, 이미지 1/1
    • 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 6.75 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.

  4. iPhone 12 Battery Replacement, Mark your opening picks: 4 단계, 이미지 1/3 iPhone 12 Battery Replacement, Mark your opening picks: 4 단계, 이미지 2/3 iPhone 12 Battery Replacement, Mark your opening picks: 4 단계, 이미지 3/3
    • 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.

    • 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 clear packing tape over the iPhone's screen until the whole face is covered.

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

    • If you can't get the suction cup to stick in the next few steps, fold a strong piece of tape (such as duct tape) into a handle and lift the screen with that instead.

    • If all else fails, you can superglue the suction cup to the screen.

  6. iPhone 12 Battery Replacement, Anti-Clamp instructions: 6 단계, 이미지 1/3 iPhone 12 Battery Replacement, Anti-Clamp instructions: 6 단계, 이미지 2/3 iPhone 12 Battery Replacement, Anti-Clamp instructions: 6 단계, 이미지 3/3

    • The next three steps demonstrate the Anti-Clamp, a tool we designed to make the opening procedure easier. If you aren't using the Anti-Clamp, skip down three steps for an alternate method.

    • For complete instructions on how to use the Anti-Clamp, check out this guide.

    • Pull the blue handle backwards to unlock the Anti-Clamp's arms.

    • Slide the arms over either the left or right edge of your iPhone.

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

    • Squeeze the cups together to apply suction to the desired area.

    • If you find that the surface of your iPhone is too slippery for the Anti-Clamp to hold onto, you can use tape to create a grippier surface.

    • Pull the blue handle forwards to lock the arms.

    • Turn the handle clockwise 360 degrees or until the cups start to stretch.

    • Make sure the suction cups remain aligned with each other. If they begin to slip out of alignment, loosen the suction cups slightly and realign the arms.

  8. iPhone 12 Battery Replacement: 8 단계, 이미지 1/3 iPhone 12 Battery Replacement: 8 단계, 이미지 2/3 iPhone 12 Battery Replacement: 8 단계, 이미지 3/3
    • Support your iPhone on something sturdy such as a hardcover book so it rests hands-free and parallel to the ground; this makes it easier to work with in the following steps.

    • Use a hair dryer to heat along the bottom edge of the iPhone. The screen should feel slightly too hot to touch.

    • For complete instructions on how to use a hair dryer, check out this guide.

    • Wait one minute to give the adhesive a chance to release and present an opening gap.

    • Insert an opening pick under the screen's plastic bezel when the Anti-Clamp creates a large enough gap.

    • If the Anti-Clamp doesn't create a sufficient gap, apply more heat to the area and rotate the handle a quarter turn.

    • Don't crank more than a quarter turn at a time, and wait one minute between turns. Let the Anti-Clamp and time do the work for you.

    • Skip the next three steps.

  9. iPhone 12 Battery Replacement, Heat the bottom edge: 9 단계, 이미지 1/1
    • Use a hair dryer or a heat gun to heat the bottom edge of the iPhone for 90 seconds or until the screen is slightly too hot to touch.

    • Never leave your hair dryer in one spot for an extended period of time.

  10. iPhone 12 Battery Replacement, Apply a suction cup: 10 단계, 이미지 1/2 iPhone 12 Battery Replacement, Apply a suction cup: 10 단계, 이미지 2/2
    • 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.

  11. iPhone 12 Battery Replacement, Lift the screen slightly: 11 단계, 이미지 1/3 iPhone 12 Battery Replacement, Lift the screen slightly: 11 단계, 이미지 2/3 iPhone 12 Battery Replacement, Lift the screen slightly: 11 단계, 이미지 3/3
    • Pull up on the suction cup with firm, constant pressure to create a slight gap between the screen and the frame.

    • Insert an opening pick into the gap under the screen's plastic bezel.

    • The watertight adhesive holding the screen 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.

  12. iPhone 12 Battery Replacement, Heat the right edge: 12 단계, 이미지 1/2 iPhone 12 Battery Replacement, Heat the right edge: 12 단계, 이미지 2/2
    • Use a hair dryer to heat the right edge of the iPhone (the edge with the power button) for 90 seconds or until the screen is slightly too hot to touch.

    • Rotate your iPhone so the right edge faces you.

    • 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.
