Pull and remove the final adhesive strip.

The strip may fling the battery when it separates from the iPhone, so hold your hand over the battery to secure it—but don't press down on the battery itself, or the added pressure may cause the adhesive strip to break off underneath the battery.

If you removed all four adhesive strips successfully, skip the two next steps.

Otherwise, if any of the adhesive strips broke off underneath the battery and could not be retrieved, continue with the next step below.
