Insert the point of an opening pick into the gap created between the bottom edge of the battery and the frame.

Push the pick under the battery to cut through the adhesive and detach the battery from the frame.

Don't insert the opening pick more than halfway to avoid damaging the fingerprint sensor underneath the battery.

Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.
