Power off your iPhone before beginning disassembly.

Remove the two 6.7 mm-long pentalobe screws at the bottom edge of the iPhone.

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.

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

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.

Hold onto your iPhone securely and close the handle of the iSclack to slightly separate the screen from the rear case of the phone.

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

Skip the next two steps and continue to step 8.

If you're using a single suction handle, apply it to the bottom edge of the phone, while avoiding the curved portion of the glass.

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.

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.

Re-insert your pick at the bottom edge of the iPhone, and slide it up the right side to continue separating the adhesive.

Slide the opening pick around the top corner of the display, while gently pulling or wiggling the display down in the direction of the Lightning port.

Slide the pick to the opposite corner and cut any remaining adhesive securing the display.

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.

Open the iPhone by swinging the display up from the left side, like the back cover of a book.

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

Remove three 1.2 mm Y000 screws securing the battery connector cover bracket.

Remove the bracket.

Use the point of a spudger to pry the battery connector straight up out of its socket.

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.

Remove the two 1.2 mm Y000 screws securing the display connector bracket.

Remove the bracket.

Use the tip of a spudger to pry up and disconnect the digitizer cable.

Use the tip of a spudger to disconnect the display cable connector.

Remove the five screws securing the logic board connector bracket to the rear case:

One 1.3 mm Phillips #000 screw

One 1.5 mm Phillips #000 screw

Three 1.2 mm Y000 screws

Remove the bracket.

Use the tip of a spudger to pry the front sensor assembly connector up from its socket.

Remove the display assembly.

Remove the seven screws securing the bracket below the Taptic engine and speaker:

Three Phillips 1.4 mm screws

Two Phillips 1.7 mm screws

One Phillips 1.9 mm screw

One Phillips 1.6 mm screw

Lift the bracket from the edge nearest the battery. Don't try to fully remove it, as it's still connected via a small flex cable.

While holding the bracket out of the way, use the point of a spudger to pry up and disconnect the flex cable underneath.

Remove the bracket.

Remove the piece of black tape and the small rubber rectangle covering the Taptic Engine connector cover.

Remove the five screws securing the lower speaker:

One 2.8 mm standoff screw

One 2.3 mm standoff screw

One 2.3 mm Phillips screw

One 1.8 mm Phillips screw

One 1.6 mm Phillips screw

Remove the small bracket on the top right corner of the speaker.

Remove the Taptic Engine connector cover.

Insert a spudger under the top edge of the speaker near the edge of the iPhone's case.

Gently pry up and lift the top edge of the speaker.

Hold the speaker by its side edges and rock it side-to-side, separating the adhesive securing it to the bottom edge of the iPhone.

Pull the speaker away from the bottom edge of the iPhone until the adhesive gasket separates.

Remove the speaker.

Remove the two 1.8 mm Phillips screws securing the Taptic Engine.

Use a spudger to disconnect the Taptic Engine flex cable by prying it straight up from its socket.

Remove the Taptic Engine.

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

Peel back the first battery adhesive tab from the bottom right edge of the battery.

Slowly pull one battery adhesive tab away from the battery, towards the bottom of the iPhone.

Pull steadily, maintaining constant tension on the strip until it slips out from between the battery and the rear case. For best results, pull the strip at as low an angle as possible, without snagging it on any of the iPhone's other components.

If the battery adhesive tabs break during the removal process, use your fingers or blunt tweezers to retrieve the remaining length of adhesive, and continue pulling.

Repeat the above steps to remove the remaining three adhesive strips.

If you removed all of the adhesive strips successfully, skip the next step.

Wait about one minute for the alcohol solution to weaken the adhesive. Use the flat end of a spudger to gently lift the battery.

If any of the adhesive strips broke off and the battery remains stuck to the rear case, prepare an iOpener or use a hair dryer to heat the rear case directly behind the battery. This will help soften the adhesive.

Flip the iPhone back over and thread a strong piece of string (such as dental floss or a length of thin guitar string) underneath the battery.

Pull the string from side to side in a sawing motion all along the length of the battery to separate the adhesive. This can take some time since the adhesive is slow to deform, but with patience it will come free. Do not deform or damage the battery.

Remove the battery from the iPhone.

Adhere the battery, disconnect it, and continue reassembling your device.
