Removing the back cover of an iPhone 4 provides access to a few replaceable parts. This includes the battery, antenna and SIM card for the non-Verizon version. Be aware that removing the back cover will void your warranty. If you aren't comfortable replacing electronic components yourself, or prefer to have your device serviced by a technician, it's a good idea to forgo attempting to replace the iPhone's components. Some iPhone 4 models use Philips head screws to keep the back in place. However, Apple introduced a five-point Pentalobe screw on some iPhone 4 models. You'll need a special screw driver to remove the Pentalobe.

Step 1

Remove the two screws next to the dock connector on the bottom of the iPhone.

Step 2

Slide the back cover up toward the top of the iPhone. It will only slide up by two millimeters.

Lift the back cover off of the iPhone.


  • The Pentalobe screws will strip very easily, so it's a good idea to replace them with Philips head screws if you plan to service your own iPhone.


  • You can replace the Pentalobe screws with 3.6 mm long #00 Philips head screws after replacing the back cover.
