    Tool used on this step:
    Plastic Cards
    • Insert a Jimmy under one of the heated corners of the phone to lift it slightly.

    • Insert a plastic card underneath the slightly lifted lip on the back cover and gently glide the card under the lifted phone casing.

    • There will be a small amount of tension, but this is normal as the card is removing the adhesive within the phone.

    • Remove the back cover from the phone.

    • Use high concentration (>90%) isopropyl alcohol and a lint-free cloth to remove all adhesive residue from the back cover and the frame.

    • Grab the red tab on the right hand side and pull until the battery dislodges.

    • It will have some tension as there is tape holding the battery in place. Only remove the battery. Make sure to leave the tape as it will ensure the next battery stays in place.

    • Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.

Does the adhesive for the back cover need to be replaced? Should I heat the phone and back glass for re-assembly?

Good questions. I think “reassembly is the reverse of these instructions" is a bit simplified. I think the heat is only for removal, but perhaps it would cause the adhesive to rebond after reassembly? Can an ifixit tech comment?

Just wondering if anyone can clarify the reattachment of the rear panel, as far as whether it is recommended, or necessary, to heat it again, or get a new adhesive gasket. Thanks.

Good question! You should replace the back cover adhesive with either a custom-cut adhesive or double-sided tape such as Tesa tape. You can choose to reheat and reuse the existing adhesive, but there may be a chance that the back cover will fall off. If you’re reusing adhesive, be sure to remove any uneven adhesive chunks.

What width Tesa tape would work for the replacement of the back cover?
