iPhone 4 Contact Clip Replacement

1 단계 Rear Panel



• Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
• Power off your iPhone before beginning disassembly.
• Your iPhone 4 rear cover may have either two #000 Phillips screws or Apple's 5-Point "Pentalobe" screws (second image). Check which screws you have, and ensure you also have the correct screwdriver in order to remove them.
• Remove the two 3.6 mm Pentalobe or Phillips #000 screws next to the dock connector.
• Be sure the driver is well seated when removing Pentalobe screws, they are very easy to strip.

• Use an iPod opening tool to carefully pry the battery connector up from the ends closest to the top and bottom edges of the iPhone.
• Do not pry against the contact clip.
• Remove the contact clip from the iPhone.
• Before reconnecting the battery connector, be sure the pressure contact (shown in red) is properly positioned next to the battery connector.
• Before reassembly, be sure to clean all metal-to-metal contact points on the pressure contact as well as its contact point on the rear panel with a de-greaser such as windex. The oils on your fingers have the potential to cause wireless interference issues.
