Introduction

Use this guide to correctly apply replacement battery adhesive strips in your iPhone 5s, 5c, or SE. 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 if following this guide for the first time.

Before you begin, you should have removed the battery by following a guide like the ones linked below. Note: iPhone 5 and earlier models do not use any adhesive strips.

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

Before installing new adhesive strips, temporarily connect your new battery and check its alignment in the iPhone.
  • Before installing new adhesive strips, temporarily connect your new battery and check its alignment in the iPhone.

  • If everything looks good, disconnect the battery and remove it.

If it sticks to your finger or another surface accidentally, it must be discarded and replaced. The blue film sometimes has a defect that prevents it from peeling off, and the strips have to be discarded and replaced.

Use the flat end of your spudger or blunt tweezers to fold the black tab downward, tucking it between the lower edge of the battery and the components lining the bottom edge of the iPhone. Be extremely careful not to poke the battery with any sharp tools during this step.  Accidentally puncturing a lithium-ion battery can cause a dangerous fire.
