Find the second stretch-release adhesive's pull-tab at the upper left corner of the battery.

Be careful not to puncture the battery with the tweezers.

Grasp the tab carefully with your tweezers.

Pull the tab at a shallow angle with steady force, rolling it as it gets longer, until the entire strip comes free.

If your adhesive strips did not pull out intact, insert an opening pick under the bottom edge of the battery and pry upwards to loosen the battery.

If needed, apply a heated iOpener to the back of the phone for a minute to loosen the battery adhesive.
