iPhone 4S Earpiece Speaker Replacement
Follow these instructions to substitute a damaged earpiece speaker.
Step 1 | Rear Panel
To start the repair, ensure the iPhone's battery has a charge level of less than 25%; a fully charged lithium-ion battery presents a fire or explosion hazard if damaged.
To prevent electrical shock or damage, ensure the iPhone is completely de-energized prior to starting the repair process.
Using a Pentalobe P2 screwdriver, detach the two screws measuring 3.6 mm located adjacent to the dock connector.
To prevent damage, ensure the driver is fully engaged with each Pentalobe screw before turning, as these screws are prone to stripping.

Carefully detach the pressure contact.
Carefully detach the pressure contact.
Step 6
- Carefully disconnect the battery connector from its corresponding socket on the logic board by leveraging a plastic opening tool.
Using the tool, gently separate the connector's metal cover from the loudspeaker enclosure by inserting the tip in the gap and raising the connector's lower edge.
To detach the battery connector, move it straight up away from the logic board; avoid any lateral pressure.
Avoid applying force directly to the battery connector's socket to prevent separation from the logic board, as it is secured by four tiny solder joints.
Step 7 | Reassembly tip
Ensure the pressure contact is correctly situated during reassembly, resting atop the designated Philips screw post and orienting the gold contact so it faces the battery connector.
To prevent wireless interference caused by oils from handling, thoroughly clean the pressure contact using a degreaser like Windex or isopropyl alcohol.
Step 8
- Using a plastic opening tool, carefully wedge the tip into the gap separating the battery from the iPhone's outer casing, positioning the tool close to the device's lower edge.
Using the plastic opening tool, carefully work along the right side of the battery, lifting it incrementally at multiple locations to release the adhesive that holds it in place within the outer case, ensuring complete separation.
To loosen a tenacious adhesive bond, carefully introduce a small quantity of isopropyl alcohol with a concentration exceeding 90% beneath the battery's edge.
Allow approximately 60 seconds for the isopropyl alcohol to reduce the bond strength of the adhesive.
Carefully raise the battery using the flat, plastic tip of a specialized opening tool.
To avoid damage, do not use excessive force when removing the battery. If the adhesive is still holding, add additional alcohol to help dissolve it. Ensure the pry tool does not damage or penetrate the battery casing during removal.
To prevent damage, ensure all traces of the alcohol solution are removed by wiping with a clean cloth or by permitting complete evaporation before proceeding with battery installation.
Step 9
Gently lift the battery away from its adhesive backing by grasping the visible, transparent plastic tab.
Exercise caution when drawing back the plastic tab, as it is susceptible to tearing with minimal force.
Disconnect the power source by detaching the battery.
Carefully detach the protective plastic packaging from the new battery by gently separating it from the ribbon cable.
Before installing the new battery, ensure the included cable is formed into the correct contour.
To confirm correct positioning during battery replacement, briefly attach the battery connector to the device; after securing the battery with adhesive, detach the connector.
Following reassembly, execute a full system reset to proactively avoid potential problems and streamline any subsequent diagnostic procedures.
Step 10 | Dock Connector Cable
Using appropriate tools, detach the cover protecting the dock connector cable by unscrewing the screws that hold it in place.
Use a Phillips screwdriver to tighten a single screw with a 1.5 mm head.
Use a Phillips screwdriver to tighten a single screw with a 1.2 mm head.
Carefully detach the metal cover protecting the dock connector cable.
Step 11
Carefully lift the dock cable connector from its socket on the logic board using the tip of a plastic opening tool.
Step 12
Carefully detach the dock connector cable from its adhesive attachment points, both where it adheres to the logic board and to the speaker enclosure’s side.
Step 13
Carefully lift the cellular antenna cable connector from its corresponding socket on the logic board, utilizing the edge of a plastic opening tool for leverage.
Carefully maneuver the cellular antenna cable so it clears the metal finger protrusions secured to the logic board.
