Repeat the above steps to remove the remaining three adhesive strips.

Be sure to hold onto the battery as you remove the final strip, or it may fling out of the iPhone unexpectedly.

If you removed all of the adhesive strips successfully, skip the next step.

If the adhesive breaks off underneath the battery and can't be retrieved, apply a few drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery in the area of the broken adhesive strip(s).

Wait about one minute for the alcohol solution to weaken the adhesive. Use the flat end of a spudger to gently lift 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.

Be careful not to damage the ribbon cables or the wireless charging coil directly underneath the battery.
