Removal

1. Use ESD-safe tweezers to remove three battery adhesive strips.

   • Grasp the battery adhesive tab. Gently peel the adhesive tab away from the battery.

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

   • Twist the tab around the tweezers and pull up 1 inch until you see white adhesive strip on the tweezers.

   • Keep the tweezers close and parallel to the battery. Then pull the tweezers toward the top of the iPhone and continue to twist and pull the adhesive until you’ve removed the entire strip. Repeat the process for the second and third adhesive 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. Wrap the tab or strip around the tweezers and continue to twist and pull the adhesive until you've removed the entire strip.

   • Important: If a battery adhesive strip breaks and can't be retrieved, attempt to remove the battery by inserting the flat end of the black stick only into one of the insertion points as shown. Ensure that the black stick is inserted into a point where the battery strip has been fully removed.

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

     

2. Remove the battery from the enclosure.
