Use this guide to correctly apply replacement battery adhesive strips in your iPhone 8, iPhone 8 Plus, iPhone XR, or iPhone SE 2020. (For earlier iPhone models, refer to this guide instead.) Any time you remove the battery, these strips must be replaced. The strips are easily damaged if not applied correctly, so you may want to have a spare set of strips on hand when following this guide for the first time.

These adhesive strips are different from those in prior-generation iPhones due to the presence of the wireless charging coil. The coil lies directly underneath the battery, which is secured with four adhesive strips that are contoured around the coil to avoid damaging it.

Before you begin, you should have removed the battery by following a guide like the ones linked below:

If you need to replace the adhesive strips in a different model iPhone, use one of the following guides:

    • Double-check the orientation of the adhesive strips, and then stick them to the back side of your new battery.

    • Make sure the two shorter strips are nearest the battery cable connector.

    • Center the strips so that the two pairs of black tabs protrude evenly from each side of the battery.
