This guide shows how to cut and apply new stretch release adhesive strips when you’re replacing a battery.

Note: This guide depicts several different phones and batteries during the procedure. Your adhesive application may vary slightly from the photos depicted in this guide, but the method remains the same.

  1. Keep track of the approximate location of the old battery adhesive. It may be helpful to take a quick photo to reference later.

    • Begin by removing all of the old adhesive and residue from the adhesion surfaces in the battery well.

    • You can pull the adhesive off with tweezers or your fingers, roll it up on the tip of a spudger with a roll-and-pull motion, or scrape it off with the flat end of a spudger.

  9. Carefully align the exposed portion of the adhesive strips along the edge of the front of the battery, and press them gently into place. Some devices need to have the battery pull tabs located near the top of the device, and some have them located near the bottom. Evaluate what will work for your repair. Take care to line up the strips correctly the first time. Once they adhere to the battery, they can't be removed and realigned.
