Adhesive secures the top and bottom edges of the battery to the frame. Heating the back cover softens the adhesive, making it easier to separate.

Carefully flip your phone over and lay it down on your workspace.

Use a hairdryer or heat gun to heat the left side of the back cover, near the top and bottom edges of the battery. It should be slightly too hot to touch.

Be careful not to heat the phone hotter than this—the battery is susceptible to heat damage.
