This step can be completed using either adhesive remover or high concentration (over 90%) isopropyl alcohol.

Prop the bottom edge of the phone up to angle the phone so that the adhesive remover will run from the bottom of the battery toward the top.

Apply 1-2 drops of isopropyl alcohol or adhesive remover along the bottom edge of the battery. Allow it to sit for several minutes to allow the adhesive to weaken.

Using too much alcohol or adhesive remover can damage the display.
