The adhesive is strongest in the bottom right and top left corners.

Apply a suction handle to the back cover, as close to the bottom edge as possible.

Pull up on the suction handle with strong, steady force to create a gap between the cover and the frame.

Strong adhesive secures the battery to the frame.

Use a pipette or syringe to apply 1-2 drops of high-concentration isopropyl alcohol (greater than 90%) between the right edge of the battery and frame.

Using too much alcohol can damage the display.

Elevate the right edge of the phone for one minute to allow the isopropyl alcohol to flow under the battery and soften the adhesive.

Take care not to puncture the battery—it can leak dangerous chemicals and/or catch fire.

Apply a suction cup to the battery, as close to the center of the right edge as possible.

Insert the tip of an opening pick between the right edge of the battery and frame.

Push the opening pick down and rotate it so the long end is between the battery and frame.

Pull up on the suction cup with strong, steady force while prying the battery up with the opening pick.

Maintain constant pressure on the pick and suction cup until the battery separates from the frame.

Be patient and allow time for the adhesive to separate. If the battery doesn't budge, apply a few more drops of isopropyl alcohol and try again.

Remove the battery.

If you used isopropyl alcohol, wait ten minutes before installing the new battery to allow the alcohol to completely evaporate.
