    • Before you begin, switch off your phone.

    • Secure a suction handle to the bottom of the back cover, as close to the edge as possible.

    • Lift the back cover with the suction handle to create a small gap between the cover and the frame.

    • Insert an opening pick into the gap.

    • If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Slide the opening pick to the bottom left corner.

    • Insert a third opening pick at the bottom left corner.

    • In the next few steps whilst cutting around the rear camera make sure you only use the tip of the opening pick to avoid smearing the lens or damaging the camera.

    • Start to slide the tip of the opening pick from the bottom left corner along the side of the phone to cut the adhesive.

    • Leave the opening pick in its place at the top left corner to prevent the adhesive from resealing.

    • Insert a fourth opening pick under the top left corner of the back cover.

    • Slide the opening pick along the top edge of the phone to cut the adhesive.

    • Leave the opening pick in the top right corner to prevent the adhesive from resealing.

    • Use a pair of tweezers and grab the pull tab at the top right corner of the battery.

    • Pull out the adhesive strip with a pair of tweezers.

    • Make sure you pull out the strip in a slow and steady motion and in a flat angle. To prevent the adhesive strip from ripping, it is helpful to twist the strip around the tweezers.

    • In case one of the adhesive strips rips and it’s not possible to pull it out completely, you can use high isopropyl alcohol (>90%) and/or a heated iOpener to loosen the adhesive. After the adhesive is soft enough use a prying tool such as an opening pick, a plastic/playing card or a spudger to carefully pry out the battery.

Conclusie

If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.

Secure the battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the phone at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (+90%).

Take your e-waste to an R2 or e-Stewards certified recycler.
