iPhone "L-Shaped" Battery Adhesive Strips Replacement

The updated framework for the HTML code is presented below.

This instructional document details the proper procedure for installing replacement battery adhesive strips on iPhone batteries with an L-shaped design.The instructions cover dual-cell batteries found within the iPhone X and XS Max, and the single-cell battery utilized in the iPhone XS.

  • Replacement batteries that lack pre-applied adhesive strips, or when reusing an existing battery, necessitate the installation of these strips.
  • Careless handling can easily compromise the integrity of these strips, so a backup set is recommended for initial use.

These strips differ from those used in earlier iPhone models because of the integrated wireless charging coil; the coil's position directly beneath the battery requires four contoured strips to prevent damage during securing.

  • For battery adhesive strip replacement on alternative iPhone models, consult the specific instructions provided in one of the following guides.

  • As a preliminary step, attempt to seat the replacement battery within the iPhone's casing.
    Achieving optimal results is best accomplished following the reinstallation of both the speaker assembly and the Taptic Engine; consult the disassembly instructions for detailed procedures.
    Ensure proper alignment of the battery connector with the corresponding socket on the logic board.
    Exercise caution to avoid contact with the Face ID camera and associated sensor components located in the upper portion of the device, specifically within the 'notch' area.

  • Following a satisfactory assessment of the battery's fit, detach the battery and position it with the connector contacts facing upward on a stable work area.
    Should your replacement battery incorporate fresh adhesive strips, proceed directly to Step 7 of this procedure.
    When working with a two-cell battery assembly, confirm that the individual cells are oriented in the same manner as they are within the iPhone's internal structure.

  • Detach the disposable blue plastic covering from the fresh adhesive strips, ensuring it is disposed of properly.
    The adhesive strips may present with either a solitary, expansive blue liner or a liner composed of two separate sections; ensure complete removal of all liner material.
    Exercise caution when manipulating the exposed adhesive surface to prevent contamination or damage.

  • After the adhesive secures to the battery surface, avoid separating or adjusting its position, as errors necessitate replacement strips.
    Verify the alignment of the adhesive strips and maintain the battery's face-down orientation, ensuring the connector contacts are exposed.
    Precisely align the strips above the battery and firmly affix them according to the provided illustration.
    Position the strips slightly away from the battery's center, near the longer side.
    Ensure the black pull tabs extend uniformly beyond the battery's upper and lower borders.

  • Ensure secure placement of the strips by applying consistent pressure with either your fingertips or a soft cloth.
    To affix the black regulatory label, apply even pressure centrally onto the battery's surface.

  1. Applying pressure with your fingertip along the battery's perimeter ensures the adhesive strips remain firmly affixed.The black pull tab, located at the terminal end of each adhesive strip, is essential for separation.Successful battery removal requires verification that all four tabs—specifically, three positioned along the lower edge and one along the upper edge—are correctly engaged.
    • Proper adhesion of all four tabs, comprising three along the base and one at the top, is crucial for effective detachment.

Step 7

  • To ensure complete visibility of the adhesive strips, the pink liner must be detached and disposed of.Complete removal of the pink liner is necessary for unobstructed access to the adhesive strips.The pink liner should be taken away and thrown out, allowing for full exposure of the adhesive strips.

  1. To prevent damage, refrain from physical contact with the Face ID camera assembly and associated sensors located within the notch at the device's upper extremity during battery replacement.
    • Handle the replacement power cell with caution, ensuring proper positioning during insertion into the iPhone's internal compartment.The new power cell is the component labeled 'battery' in this procedure.Precisely position the power cell within the iPhone's designated space.
    • Ensure the battery connector's pins are correctly oriented to match the corresponding socket on the logic board.A preliminary connection of the power cell is recommended to verify proper alignment before proceeding with full reassembly.Before final reassembly, temporarily engage the battery connector to the logic board to confirm alignment, then immediately disconnect it.
    • This temporary connection serves only to validate the physical fit of the battery connector.Disconnecting the battery before reassembly prevents potential short circuits or damage during the enclosure closure process.The component referenced as 'battery connector' is crucial for establishing electrical communication between the power cell and the logic board.

  • Ensure the battery adheres securely by applying consistent pressure across its surface using the provided adhesive.To guarantee proper adhesion, firmly position the battery against the adhesive strips.Should your battery component feature a supplementary plastic covering, it must be detached and disposed of.
  • Prior to reassembling the device, eliminate any protective plastic film present on the battery’s top surface.Complete the assembly process only after the plastic liner, if present, has been removed from the battery.Failure to remove the plastic liner can interfere with the battery's connection and proper function.
