Google Pixel 4 Charging Assembly Replacement

Insert a SIM eject tool, bit, or a straightened paper clip into the small hole on the SIM card tray.

Press firmly to avoid damaging the SIM card tray.

• Remove the SIM card tray from the phone.

Prepare a iOpener and apply it to the bottom edge of the back panel for 1 minute.

Alternatively, use a hair dryer, heat gun, or hot plate, but be careful not to overheat the phone, as the display and internal battery can be damaged by excessive heat.

Apply a suction cup to the heated edge of the back panel, pressing down firmly to create suction as close to the edge as possible.

• If the back glass is badly cracked, cover it with clear packing tape for better adhesion.
• Alternatively, use very strong tape instead of the suction cup.

• As a last resort, superglue the suction cup to the broken panel.

Apply suction cup with strong, steady force to create a gap between back panel and frame.

• If necessary, reapply heat to the edge before trying again.
• Insert point of an opening pick into the created gap.

Insert a pick tool into the device.

• Slide the pick across the bottom towards the left corner to cut the adhesive.
• Move the pick from the bottom left corner over to the bottom right corner to fully slice the adhesive.

Leave the pick inserted in the bottom right corner to prevent re-sealing of the adhesive.

Apply iOpener to the left edge of the phone for 1 minute.

Insert an additional opening pick under the back panel, positioned over the charge port.

• Move the pick towards the lower left corner of the phone.

Slide the opening pick around the bottom left corner and across the left side of the phone in a sawing motion.

• The adhesive can be very gummy, so use a pushing and pulling action with the pick to help it slice through.
• Stop when you reach the top left corner near the camera and leave the pick inserted.

Prepare an iOpener and apply it to the right edge of the phone for 1 minute.

Insert a third pick at the lower right side of the phone.

• Slide the pick up towards the top, cutting the adhesive on the right side.
• Stop when you reach the top right corner and leave the pick in place.

Insert the third opening pick into the top right corner of the phone.

Work it along the top edge, carefully cutting the remaining strip of adhesive.

Do not attempt to remove the panel completely at this time.

• Lift the right edge of the back cover, opening it like a book.
• Leave the panel partially attached for now.

Continue swinging open the back panel until it rests on the left edge of the phone, taking care not to stress the attached ribbon cable.

Do not power on your phone while reassembling unless explicitly testing before sealing the back panel.

Power down your phone completely before continuing work.

Remove the T3 Torx screws securing the battery connector shield.

• Four 4.0 mm T3 Torx screws
• 2.1 mm T3 Torx screw

Label and keep track of each screw for reinstallation purposes.

Use tweezers to remove the battery connector shield.

Be extremely cautious when using a spudger near the battery to avoid puncturing it.

• Use the pointed end of a spudger to gently pry the battery connector straight up from the motherboard.
• To reattach, align and press down on one side until it clicks; repeat on the other side. Avoid pressing the middle.

Misaligned connectors can cause pin bending and permanent damage, so ensure proper alignment before pressing.

Use the flat end of a spudger to gently fold the battery cable out of the way.

Accidental contact can cause damage or injury.

Remove the T3 Torx driver and use it to loosen the two 4mm screws securing the back panel connector cover.

Remove the back panel connector cover using a pair of tweezers.

Use the pointed end of a spudger to pry up the back panel connector.

• Pry gently until the connector releases.
• Carefully pull the connector away from the device.

Remove the back panel.

• For custom adhesives, refer to the installation guide provided.
• If using a pre-cut adhesive card, follow its accompanying instructions.

Hold the yellow pull tab firmly and gently pull up with steady force.

• If the adhesive is stubborn, roll it around a spudger to continue pulling.
• Spin the spudger occasionally to keep the exposed section of the pull tab short.

This may require significant force and be patient, as these tabs are prone to snapping in half.

• If no progress is made after several attempts, try applying a few drops of high concentration (>90%) isopropyl alcohol under the left edge of the battery, allowing it to weaken the adhesive for 1 minute before continuing.
• Repeat this process for each of the three pull tabs until they are removed or have snapped in half.

Never insert the opening pick near the charge port flex cable to avoid damaging it.

• Insert an opening pick on the upper right edge of the battery to slice the adhesive underneath.
• If needed, use the opening pick to dislodge the battery even if all three adhesive pull tabs are removed.

Do not reuse a deformed or damaged battery — replace it with a new one to avoid safety hazards.

• Lift the old battery out of the phone, peeling away any leftover adhesive tabs as needed.
• Wipe off any remaining alcohol solution from the phone using a lint-free cloth or let it air dry before installing the new battery.

Use stretch release adhesive on the replacement battery, or double-sided tape/adhesive strips in the phone's well (avoiding the charge port flex cable).

• Temporarily reconnect the battery connector to its motherboard socket for proper positioning.
• Lay the new battery in place and press firmly.

Disconnect the battery connector from the motherboard socket and resume re-assembly.

Remove the T3 Torx screws from the vibration motor cover.

• One 4.2 mm screw
• One 4.4 mm shouldered screw

Remove vibration motor shield with a pair of tweezers.

Remove the two T3 Torx screws securing the loudspeaker.

• One 4.2 mm T3 Torx screw.
• One 4.4 mm shouldered T3 Torx screw.

Use tweezers to gently slide the loudspeaker towards the top of the phone.

Ensure the retention clip is cleared before proceeding.

• Remove the loudspeaker.
• Before reassembling, inspect the adhesive gasket:
• If in good condition, reuse and ensure it does not cover the exit hole.
• If out of place or damaged, remove it and replace with a new pre-cut strip or Tesa tape.

Disconnect the charging cable connector using the flat end of a spudger, prying it straight up from the motherboard.

Disconnect the antenna press connector using a pair of tweezers, pulling it straight up from the motherboard.

Disconnect vibration motor connector from charging assembly.

Remove the T3 Torx using a driver handle, if necessary.

• Loosen the 2.1 mm screw on the left side.
• Next, remove the 2.1 mm screw located at the bottom of the device.

Remove the ribbon cable from the phone's frame using a gentle prying motion.

Be careful not to damage the cable or its connector, as it is adhered lightly with adhesive.

• Remove the charging assembly.
• If your replacement charging assembly does not include the white antenna cable, transfer it to your new part.
