Use an opening pick to steadily pry the battery up, starting from the outer edge of the battery.

You may need to reheat and reapply the iOpener repeatedly to further soften the adhesive. The adhesive is tough and it may take a few tries to get the pick started under the battery. If the battery begins bend out of shape, apply more heat or isopropyl alcohol and pry slower.

Try your best not to deform the battery during this process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.

Remove the battery.

Reinstalling a damaged or deformed battery is a safety hazard. Replace it with a new battery.

During reassembly, remove any remaining tape under the battery and clean any residual adhesive with isopropyl alcohol. If you are reusing the screen assembly, apply new precut battery adhesive or high-strength double-sided tape to the battery well before pressing the new battery into place.
