Anleitung

Prepare the phone for disassembly
Vorsicht: Caution Allow the phone's battery to drain below 25%, as a charged lithium-ion battery is a potential safety hazard.

Unplug any cables from the phone.

Hold the power and either volume buttons and slide to power off the phone.
Tape over any cracks
If the screen or back glass is badly cracked, lay overlapping strips of packing tape over the glass to protect yourself and make disassembly easier.

Hinweis: Note Make sure there's a smooth area near the bottom edge that's big enough for a suction cup to stick to.
Mark your opening picks
Hinweis: Note 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.

Hinweis: Note You can also mark the other corners of the pick with different measurements.

Hinweis: Note Alternatively, <a href="https://guide-images.cdn.ifixit.com/igi/pQGATIGUbViSB4gB.full" target="_blank">tape a coin to a pick</a> 3 mm from the tip.
Remove the pentalobe screws
Use a P2 pentalobe screwdriver to remove the two 7.4 mm‑long screws on either side of the USB-C port.
Heat the bottom edge
Apply a heated iOpener to the bottom edge of the back glass for two minutes.

Hinweis: Note Alternatively, you can use a <a href="https://www.ifixit.com/Guide/How+to+Use+a+Hair+Dryer+to+Soften+Adhesive/157348" target="_blank">hair dryer</a> or <a href="https://www.ifixit.com/Guide/How+to+Use+a+Heat+Gun+to+Soften+Adhesive/151116" target="_blank">heat gun</a> to heat the bottom edge of the back glass until it's hot to the touch.

Vorsicht: Caution Be careful not to heat the phone hotter than this—the battery is susceptible to heat damage.
Insert an opening pick
Apply a suction handle to the bottom edge of the back glass, above the USB-C port.

Pull up on the handle with a strong, steady force to create a gap between the back glass and the frame.

Insert the tip of an opening pick into the gap.
Back glass information
Vorsicht: Caution As you slice the adhesive securing the back glass in the next steps, be careful of the following areas:

There's a delicate cable connecting the back glass to the phone, right next to the volume up button. Don't insert your pick here to avoid slicing the cable.

There are multiple spring contacts around the perimeter of the phone. Be extra careful not to insert your pick deeper than suggested in each step to avoid bending these contacts.

Hinweis: Note If you damage the spring contacts, gently bend them back with a spudger or opening pick so they align with their gold contact pads on the back glass.
Separate the bottom edge adhesive
Vorsicht: Caution Don't insert your pick deeper than 5 mm on the bottom edge to avoid damaging the <a href="https://guide-images.cdn.ifixit.com/igi/6VJ6BvBUgEVZJfTK.full" target="_blank">spring contact</a>.

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 resealing.
Heat the right edge
Heat the right edge of the back glass until it's hot to the touch.
Separate the bottom right corner adhesive
Slide your pick around the bottom right corner and halfway up the right edge, or until you feel a hard stop at a clip securing the back glass.

Vorsicht: Caution Don't slice near the volume buttons to avoid damaging the <a href="https://guide-images.cdn.ifixit.com/igi/BCE4BVXQBj614vJg.full" target="_blank">wireless charging/flash cable</a>.

Leave this pick inserted to prevent the adhesive from resealing.
Heat the left edge
Heat the left edge of the back glass until it's hot to the touch.
Separate the left edge adhesive
Insert a second opening pick at the bottom edge.

Slide the second pick around the bottom left corner and along the left edge of the screen to separate the adhesive and release the metal clips.

Hinweis: Note You'll hear and feel the metal clips release as you pass them.

Leave this pick inserted at the top left corner to prevent the adhesive from resealing.
Heat the top edge
Heat the top edge of the back glass, including the area around the volume buttons, until it's hot to the touch.
Separate the top edge adhesive
Vorsicht: Caution Don't insert your pick deeper than 3 mm along the top edge to avoid damaging the <a href="https://guide-images.cdn.ifixit.com/igi/E2B65UGPRFnwJE1I.full" target="_blank">spring contacts</a>.

Slide your opening pick across the top edge and around the top right corner to the volume up button to separate the adhesive.

Hinweis: Note You'll hear and feel clicks as the top two clips release.
Swing open the back glass
Vorsicht: Caution Don't try to fully remove the back glass just yet—it's still attached with a delicate ribbon cable. Follow the next few steps to remove it safely.

Hinweis: Note If the back glass doesn't swing open easily, don't force it—go back around the perimeter with your pick to check for missed sections of adhesive or stuck clips.

Hinweis: Note You may need to lift the back glass up slightly before swinging it open to fully disengage the clips.

Gently swing open the back glass towards the volume buttons.

Support the back glass with a clean, sturdy object like a small box to avoid straining the cable.

Remove the opening picks.

Hinweis: Note Consider using polyimide tape to protect the <a href="https://guide-images.cdn.ifixit.com/igi/mbOLvEXLDsTf4inF.full" target="_blank">rear camera lenses</a> while you're working inside the phone. Don't push against the lenses to avoid damaging the delicate stabilizers.

Disassembly complete
Hinweis: Note Congratulations on completing disassembly! The remaining steps will show how to reassemble your iPhone. Some of the reassembly photos show the Pro Max model, but the procedure is correct for the Pro.
Transfer the battery shim
Hinweis: Note If the <a href="https://guide-images.cdn.ifixit.com/igi/GMNZAPaHT46dliUb.full" target="_blank">black plastic shim</a> beneath the battery didn't come out with the loudspeaker, skip this step.

Align the battery shim so it's flush with the new loudspeaker's left edge and underside. Press it onto the loudspeaker to adhere it.

Hinweis: Note If the shim isn't sticky, set it into the phone alongside the loudspeaker in the next step.
Install the loudspeaker
Align the bottom edge of the loudspeaker with the frame.

Set the loudspeaker into its recess.
Step 38
Install the four screws securing the loudspeaker:

Two 1.6 mm‑long Phillips screws

One 2.0 mm‑long Phillips screw

One 1.3 mm‑long tri-point Y000 screw
Install the Taptic Engine
Use blunt-nose tweezers or your fingers to align the Taptic Engine with its screw posts and place it in the frame.
Step 40
Use a Phillips screwdriver to install the 1.9 mm‑long screw securing the Taptic Engine, located on its right edge.
Connect the lower assembly cable
Use your finger or a spudger to connect the two lower assembly press connectors.

Hinweis: Note These press connectors can be tricky. Align each connector over its socket and press down—first on one side, then the other—until it clicks into place. Don't try to force them. If you're having trouble, reposition them and try again.
Step 42
Use a tri-point Y000 screwdriver to install the 1.0 mm‑long screw securing the lower assembly cable.
Step 43
Use your finger or a spudger to connect the lower assembly cable press connector, located in the bottom-right corner of the logic board.

Hinweis: Note Make sure the bottom edge of the cover <a href="https://guide-images.cdn.ifixit.com/igi/2I1SmffIGfHo6MHm.full" target="_blank">latches properly to the frame</a>.
Step 45
Use a Phillips screwdriver to install the three screws securing the Taptic Engine cover:

One 3.0 mm‑long screw

Two 1.7 mm‑long screws
Remove the leftover adhesive
Vorsicht: Caution Work around the fragile grounding clips as you're cleaning the frame. If you bend one out of place, gently bend it back with your fingers or tweezers.

Use blunt nose tweezers or your fingers to remove large pieces of adhesive from the frame perimeter.

Use a spudger to scrape the adhesive residue off of the frame.

Hinweis: Note If the adhesive feels stubborn, apply some heat using a <a href="https://www.ifixit.com/Guide/How+to+Use+a+Hair+Dryer+to+Soften+Adhesive/157348" target="_blank">hair dryer</a> or <a href="https://www.ifixit.com/Guide/How+to+Use+a+Heat+Gun+to+Soften+Adhesive/151116" target="_blank">heat gun</a> and try again.
Clean the back glass
If you're reusing your back glass, apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to a microfiber or lint-free cloth and wipe around the perimeter to prepare the surface for new adhesive.
Clean the frame
Wrap a lint-free cloth or a coffee filter over the point of a spudger and apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to it.

Wipe in one direction along the perimeter of the frame to clean the adhesive residue.

Hinweis: Note Take your time doing this. A clean frame allows replacement adhesive to lay evenly, ensuring a better bond.
Apply the replacement adhesive
Lay the adhesive sheet over the frame to determine its proper orientation.

Hinweis: Note Use features such as the camera cutout and notches along the top and bottom edges to visualize how the adhesive will lay in the frame.
Step 50
Grab the tab in the corner of the adhesive sheet and peel the liner to expose a third of the adhesive.

Vorsicht: Caution The exposed adhesive is very sticky. Don't let it touch anything until you're ready to apply it to the frame.

Hinweis: Note If your adhesive has multiple liners, peel the liner that exposes the side that sticks to the frame.
Step 51
Carefully align the exposed edge of the adhesive strip with the corresponding edge of the iPhone's frame.

Vorsicht: Caution Once the adhesive is pressed into place, you can't reposition it—you'll have to remove it and start over with new adhesive.

When it's correctly aligned, gently press the exposed adhesive strip onto the frame.
Step 52
Continue peeling away the liner from the adhesive, gently pressing the adhesive into place.

Hinweis: Note If you've correctly aligned the adhesive, the edges will fall perfectly into place.

Hinweis: Note If your adhesive is slightly misaligned, gently pull the long edges into alignment with the frame.

Hinweis: Note If the adhesive begins to crease or wrinkle, remove it and start over with fresh adhesive.

Hinweis: Note If you don't have another set of adhesive strips handy, it's okay to temporarily put your iPhone back together and use it normally without any adhesive. Just keep in mind that your iPhone's water resistance will be compromised until you replace the adhesive.
Step 53
Use a spudger to press the adhesive around the entire perimeter of your iPhone.

Vorsicht: Caution Work around the fragile grounding clips. If you bend one out of place, gently bend it back with your fingers or tweezers.

Hinweis: Note Don't press too hard, or you'll stretch and deform the adhesive.
Step 54
Use a spudger or your fingers to lift the pull tab connected to the large front liner. The pull tab is often in a corner of the liner.

Use the pull tab to peel off the large front liner from the adhesive.

Hinweis: Note At this point, you may still have a liner covering the perimeter, which prevents the adhesive from accidentally sticking to anything while you're reassembling your iPhone. Don't remove these small release liners just yet.
Connect the back glass
Prop up the back glass along the right edge of your iPhone.
Step 56
Use your finger or the flat end of a spudger to press and connect the back glass connector onto the logic board.
Connect the battery
Use your finger or a spudger to press and connect the battery press connector onto the logic board.

Hinweis: Note This is a good point to test your repair before sealing up your iPhone. Power on your iPhone and make sure it works as expected. Power it back down and continue reassembly.

Hinweis: Note If your iPhone doesn't turn on, connect it to a power source and try again.

Hinweis: Note If you've replaced the logic board and the screen fails to turn on, you'll need to follow the <a href="https://www.ifixit.com/Guide/iPhone+16+Pro+Max+Screen+Replacement/178634" target="_blank">screen guide</a> to manually connect the display connector.
Install the connector covers
Align the back glass connector cover by its screw holes and lay it in place.
Step 59
Use a tri-point Y000 driver to install the four screws securing the back glass connector cover:

Two 1.3 mm‑long screws

Two 1.0 mm‑long screws
Step 60
Align the battery connector cover by its screw holes and lay it in place.
Step 61
Use a tri-point Y000 driver to install the three screws securing the battery connector cover:

Two 1.3 mm‑long screws

One 1.0 mm‑long screw
Remove the final adhesive liners
Use your fingers or a spudger to peel away all perimeter liners, exposing the adhesive.

Hinweis: Note As you remove the liners, make sure nothing touches the exposed adhesive.

Check the frame and back glass for any stray liners and remove them. There should be no liners remaining.
Install the back glass
Lower the back glass onto the frame, beginning with the top edge.

Vorsicht: Caution If you feel resistance, a perimeter clip may have bent out of place and is being crushed by the frame. Look at the point of resistance and gently straighten any bent clips.

Press along the edges of the iPhone until the back glass sits flush against the frame.
Apply heat to the perimeter
Use a hair dryer, heat gun, or an iOpener to heat the back glass perimeter until it's slightly too hot to touch.

Hinweis: Note The heat softens the adhesive and helps create a better bond.
Apply pressure to the perimeter
Use your fingers to firmly squeeze around the perimeter of the iPhone.
Step 66
Place your iPhone screen-side down on a clean, flat work surface.

Lay a strip of tape around the perimeter of the back glass to protect the finish.

Stack coins around the perimeter of the back glass until you create a wall that's as tall as the rear camera protrusions.

Hinweis: Note Alternatively, you can use <a href="https://www.ifixit.com/Guide/How+To+Use+Screen+Vise+Clamps/142291">vise clamps</a> around the perimeter of your device to set the new adhesive.
Step 67
Place 3-4 heavy books squarely on top of your iPhone.

Vorsicht: Caution The coins may leave a slight impression on the bottom book cover, so don't use anything valuable.

Leave the books in place for about 30 minutes.

Hinweis: Note The pressure will help activate the adhesive.
Install the pentalobe screws
Use a P2 pentalobe screwdriver to install the two 7.4 mm‑long screws on either side of the USB-C port.
