Removal

  1. Place the enclosure in the repair tray with the Lightning connector facing the cutout. Use ESD-safe tweezers to gently peel the two adhesive tabs from the bottom of the battery.

  2. Hold down the iPhone with one hand. With the other hand, grasp one adhesive tab and slowly pull it toward the bottom of the iPhone. As the adhesive strip stretches, grasp it closer to the battery and continue pulling until you’ve removed the entire strip.

    • Caution: Don’t pull the adhesive strip against parts or screws.

    • Important: If the battery adhesive tab or strip breaks off and you can still see it, attempt to retrieve it with your fingers and repeat step 2. If you can’t see the tab or strip, continue to step 3.

  3. Repeat step 2 to remove the other adhesive strip from the bottom of the battery. If you remove the entire strip, continue to step 4.

    • Important: If the second bottom battery adhesive tab or strip breaks off and you can still see it, attempt to retrieve it with your fingers and repeat step 2. If you can’t see the tab or strip, continue to step 4.

  4. Use ESD-safe tweezers to gently peel the two adhesive tabs from the top of the battery.

    • Note: The center of the top battery adhesive tab is perforated. The battery tab separates into two tabs as you lift one side.

    • Warning: Don’t scrape or puncture the battery with the tweezers.

  5. Hold down the iPhone with one hand. Use ESD-safe tweezers to grasp one adhesive tab and slowly pull it upward. Twist the tweezers to wrap the adhesive strip around them until you’ve removed the entire strip.

    • Caution: Don’t pull the adhesive strip against parts or screws.

    • Important: If the battery adhesive tab or strip breaks off and you can still see it, attempt to retrieve it with the tweezers and repeat step 5. If you can’t see the tab or strip, continue to step 6.

  6. Repeat step 5 to remove the remaining battery adhesive strip from the top of the battery. If you remove the entire strip, continue to step 7.

    • Important: If the battery adhesive tab or strip breaks off and you can still see it, attempt to retrieve it with the tweezers and repeat step 5. If you can’t see the tab or strip, continue to step 7.

  7. If all four battery adhesive strips were fully removed, continue to step 9. If at least one strip was fully removed, continue to step 8.

    • Warning: If all four strips were broken and can’t be retrieved, don’t forcibly pry the battery. Stop the repair. You can find a service option at support.apple.com/repair.

    • Caution: When using the black stick to remove the battery from the enclosure, don’t damage the flex cables. Don’t scrape, rip, tear, or otherwise damage the polyester film or other areas (1). If damage occurs, replace the iPhone.

  8. Insert the flat end of the black stick only into one of the insertion points marked by an arrow (2). Ensure that the black stick is inserted into a point where the battery strip has been fully removed. Don’t insert the black stick into a point where the battery tab or strip is broken.

  9. Use the black stick to tilt up the battery just enough to grasp it underneath.

    • Caution: To avoid damage, don’t press the black stick on the edge of the enclosure.

  10. Remove the battery from the enclosure. Then inspect the enclosure for damage. If the enclosure is damaged, replace the iPhone.

    • Warning: If you can’t remove the battery, stop the repair. You can find a service option at support.apple.com/repair.

Reassembly

  1. Use ethanol wipes or IPA wipes on the area shown in green to remove all residual adhesive from the enclosure.

    • Caution: Don’t use ethanol wipes or IPA wipes on the area outlined in red. Ethanol or isopropyl alcohol may damage the polyester film and wireless charging unit.

    • Warning: Inspect the enclosure for loose or extra screws and small parts, which can damage the battery and cause safety issues.

  2. Peel the pink release liner from the underside of the replacement battery.

  3. Rest the right edge of the battery in the enclosure. Press the end of the battery flex cable to the connector.

    • Caution: Temporarily connecting the battery flex cable prevents cable damage and ensures correct battery position.

  4. Tilt down the left side of the battery.

  5. The repair tray has a slot in the center. Position the repair tray and enclosure into the battery press with the slot over the pin as shown.

  6. Flip down the red lever at the top of the battery press to lower the roller onto the battery.

  7. Slide the repair tray back and forth through the battery press three times to adhere the battery to the enclosure.

  8. Flip up the red lever.

  9. Remove the repair tray from the battery press.

  10. Use the black stick to lift the end of the battery flex cable off the connector.

    • Caution: Leave the battery flex cable off the connector until display reassembly.

Reinstall the following parts to complete reassembly:

Warning

Gently shake the iPhone. If the battery is loose, remove the display, repeat battery reassembly steps 5 through 10, and reinstall the display. If the battery is still loose, complete battery reassembly with another replacement battery.

Important

A new battery is not charged. After you’ve completed all removal and reassembly steps, charge the device for a few minutes.

Caution

  • After you’ve completed all removal and reassembly steps, initiate System Configuration by putting the device into diagnostics mode. Tap Start Session and follow the onscreen prompts.

  • You’ll have one attempt to complete System Configuration. If the attempt is interrupted, canceled, or encounters an error, the device will display a message instructing you to contact the Self Service Repair Store team for assistance.
