Use this guide to replace the dock connector assembly, which includes the dock connector and lower microphone.

  1. Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • 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.

    • Remove the two 3.6 mm Pentalobe P2 screws next to the dock connector.

    • Be sure the driver is well-seated when removing Pentalobe screws—they are easy to strip.

  6. Use a plastic opening tool to gently pry up the battery connector from its socket on the logic board. Place the tip of the tool between the loudspeaker enclosure and the metal cover of the connector, and lift the bottom edge of the connector first. The battery connector comes off vertically from the logic board. Do not apply force sideways.

  7. During reassembly, be sure to carefully position the pressure contact back in place. It should rest on top of the Philips screw post shown, and the gold contact should point towards the battery connector. Be sure to clean the pressure contact with a degreaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to create wireless interference.

  8. Insert the edge of a plastic opening tool between the battery and the outer case near the bottom of the iPhone. Run the plastic opening tool along the right edge of the battery and pry up at several points to completely separate it from the adhesive securing it to the outer case.

    • Insert the edge of a plastic opening tool between the battery and the outer case near the bottom of the iPhone.

    • Run the plastic opening tool along the right edge of the battery and pry up at several points to completely separate it from the adhesive securing it to the outer case.

    • If the adhesive is too strong, apply a few drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery.

    • Wait about one minute for the alcohol solution to weaken the adhesive.

    • Use the flat end of a plastic opening tool 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.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off or allow it to air dry before installing your new battery.

  10. Use the exposed clear plastic pull tab to peel the battery off the adhesive securing it to the iPhone. Be careful not to pull the plastic pull tab too hard as it can be ripped off very easily.

    • Be careful not to pull the plastic pull tab too hard as it can be ripped off very easily.

    • Remove the battery.

    • If your replacement battery came in a plastic sleeve, remove it before installation by pulling it away from the ribbon cable.

    • If your replacement battery came with an uncreased cable, carefully crease the cable into the proper shape before installing the battery into the phone.

    • While installing the replacement battery, temporarily connect the battery connector to the phone to ensure proper alignment. Once the battery is glued in place, disconnect the battery connector.

    • Perform a hard reset after reassembly. This can prevent several issues and simplify troubleshooting.

After re-assembling the phone I get searching or very low signal, and the signal that i get is not 3G.

Does anyone have any suggestions?

I have cleaned the connectors and made sure that all connections were tight.

THe #00 screw driver does not work for all screws in the 4S so a smaller one is needed. Wasted my money on that one.

When I had changed the dock connector, my iPhone was not able to get a carrier signal. I found an helpful answer in the forum which worked perfectly for me. Make sure you set the correct date and time (after you remove the battery, it will most probably show you 1970) remove the sim card and plug it in again. That worked for me.

I bought the pro tech toolkit and liberation kit and set my work area to the longest one hour of my life. Everything inside the 4s is so tiny and fragile, I was in constant fear of breaking something, but the teardown videos and the comments on this page really help me to get through the entire process.

Thank you everybody and let us continue tinkering our way through all the adversities in this life! Peace!

This guide was perfect! Very detailed and explained everything very well. Only thing I found confusing was step 17, but besides that it went perfectly smooth!
