The next two steps show how to remove the battery if the adhesive strips broke.

Lift the bottom edge of the frame to tilt your phone.

Use a pipette or a syringe to apply 2–3 drops of high concentration (>90%) isopropyl alcohol along the bottom edge of the battery, close to where each broken adhesive strip came out.

Wait one minute for the isopropyl alcohol to flow under the battery and soften the adhesive.
