iPhone SE 2020 Battery Replacement

• As a preliminary safety measure, ensure your iPhone's battery has been depleted to a level below 25% prior to commencing any work.A lithium-ion battery that retains a chargeposes a significant fire and/or explosion hazard if it is inadvertently damaged, such as by a puncture.
• To prevent electrical hazards and potential damage, completely shut down your iPhone before starting the disassembly process.
• Using a suitable tool, detach the pair of 3.5 mm pentalobe screws located along the iPhone's lower edge.
• Separating the iPhone's display assembly will irreversibly damage its water resistance capabilities; therefore, obtain replacement sealing components beforehand, or exercise extreme caution to prevent moisture ingress if you intend to reassemble the device without new seals.

• To avoid potential harm to your device, ensure the opening pick isn't inserted beyond its intended depth; this procedure details how to identify the safe insertion point by marking the pick.
• Determine the measurement of3 mmfrom the pick's leading edge and use a permanent marker to create a visible indication on the opening pick.
• For enhanced precision, consider marking additional points on the pick's corners with varying measurements.
• As an alternative method, affix a coin to the pick's shaft,3 mmaway from its tip.

The following three procedures illustrate the function of the Anti-Clamp, a specialized tool developed to simplify the initial opening process; if you choose not to utilize this tool, proceed to the instructions three steps further down.

Detailed guidance regarding the Anti-Clamp's operation can be found in a separate, dedicated instructional document.

• To release the Anti-Clamp's gripping arms, retract the blue handle towards the rear.
• Carefully position the arms across either the left or right side of your iPhone.
• Place the suction cups close to the lower edge of the iPhone, situated directly above the home button—one on the front face and one on the rear.
• Apply pressure by compressing the cups together to establish a secure suction hold on the intended surface.
• Should the iPhone's surface prove excessively smooth, hindering the Anti-Clamp's ability to maintain grip, applying adhesive tape can provide a more textured interface.

• To secure the arms, advance the blue handle in its direction.
• Rotate the handle in a clockwise direction,covering a full circle of 360 degrees,or continue the rotation until the suction cups begin to expand.
• Maintain the proper alignment of the suction cups with one another; should they become misaligned, slightly release the suction cups and reposition the arms.

• Employ a heating device to warm aniOpenerand carefully guide it between the arms of theAnti-Clamp.
• Alternative heat sources, such as a hair dryer, heat gun, or hot plate, are acceptable; however, exercise caution as excessive temperatures may compromise the display or internal battery.
• Position theiOpenerto rest along the lower edge of the iPhone's casing.
• Allow a sixty-second interval to permit the adhesive to soften and create a separation.
• Introduce an opening tool into the newly formed space.
• Should theAnti-Clamp fail to generate an adequate separation, increase the heat applied to the area and rotate the handle by ninety degrees.
• Avoid rotations exceeding ninety degrees at a time, and observe a sixty-second pause between adjustments; allow theAnti-Clampand time to facilitate the separation process.

The following three procedures detail the process of detaching the display assembly with the aid of a suction cup.

• Applying heat to the phone's bottom edge will assist in loosening the adhesive bonds holding the display in place, which will simplify the separation process.
• Employ a hairdryer, or alternatively prepare aniOpenerand apply it to the lower edge of the device for approximately 90 seconds to reduce the adhesive's tackiness.

Securely affix a suction cup to the bottom portion of the front panel, positioning it directly over the home button area.

Ensure the suction cup's surface remains clear of the home button's location to guarantee a complete and airtight bond between the cup and the glass.

• Apply steady, forceful upward pressure to the suction cup to generate a small separation between the display assembly and the device's surrounding structure.
• Carefully slide an opening tool into the newly formed space.
• Because the screen is secured with a robust, waterproof adhesive, establishing this initial separation requires considerable effort; should you encounter difficulty, applying additional heat and gently oscillating the screen in an upward and downward motion can reduce the adhesive's strength, facilitating the creation of a sufficient gap for tool insertion.

• Begin separating the display assembly from the chassis by inserting a prying tool beneath the lower edge of the phone's left side, carefully advancing it toward the volume controls and the silent switch, which will disrupt the adhesive seal.
• Cease the separation process in the vicinity of the display's upper-left corner.
• Avoid attempting to dislodge the display's upper edge from the rear housing, because it is secured by fragile plastic retaining clips that are susceptible to damage.

Along the right side of your iPhone, you'll find sensitive wiring; avoid inserting any tools in this area to prevent potential cable damage.

• To release the adhesive, carefully reposition your tool at the lower-right edge of the iPhone, then maneuver it along the corner and up the right side, sliding it to detach the adhesive.
• Ensure your opening tool does not penetrate beyond 3 mm, to prevent potential harm to the delicate display cable connections.

• Carefully elevate the display's lower border by applying upward force to the suction cup.
• Avoid lifting the display beyond an angle of 15 degreesas exceeding this limit could potentially damage or sever the flexible ribbon cables that provide the display's electrical connections.
• Detach the suction cup from the front panel by grasping and pulling on the small protrusion located on its surface.

• To access the iPhone's internal components, initiate the opening process by pivoting the display upwards from the left edge, mimicking the action of opening a book's cover.
• Refrain from completely detaching the display at this stage, because multiple delicate ribbon cables remain connected to the iPhone's logic board.
• Secure the display in an upright position using a support to prevent it from obstructing your work area during the repair.

• Employ two screws measuring 1.3 millimeters in length.
• Also, use two screws measuring 2.8 millimeters in length.

• Employ the tip of a spudgerto carefully disengage the battery connector from its corresponding receptacle on the logic board.
• Gently deflect the battery connector cable a small distance from the logic board's surface, ensuring it remains disconnected from the socket to avoid unintended power delivery to the device during the repair process.

• Employ the tip of a spudgerto carefully disengage the lower display connector from its receptacle.
• For reattachment, apply pressure to one edge of the connector until a secure click is heard, then repeat the process on the opposing edge; avoid applying pressure to the central portion. Even minor misalignment during reattachment can result in bending of the connector, potentially leading to irreversible damage.

• Employ the tip of a spudgerto carefully separate the connector of the secondary lower display cable from its socket.

• To detach the bracket that covers the front panel sensor assembly connector, first eliminate the three 1.3 mm Phillips screws which hold it in place.
• Following screw removal, the bracket can then be taken away.

• Detach the display unit from the device.
• If you intend to substitute the adhesive securing the display's perimeter during reinstallation, momentarily halt the process at this stage.

• To detach the bracket located adjacent to the Taptic Engine, it is necessary to eliminate the three screws that hold it in place.
  • A single 1.3 mm Y000 screw is required.
  • Additionally, a single 2.7 mm Phillips screw is needed.
  • Furthermore, a single 2.9 mm Phillips screw must be removed.

• Carefully insert a separation tool between the antenna flex cable and the speaker's upper surface.
• Adhesive secures this section of the flex cable; a minimal amount of warmth, originating from aniOpeneror hair dryer, can be used to reduce the adhesive's strength, facilitating a safer separation.

• Carefully leverage the tip of a spudger to lift and detach the diversity antenna flex cable from its connection on the logic board.

• Insert a thin, flat tool beneath the antenna flex cable to maintain pressure on the connector's housing.
• Employ the tip of your spudger to lift and detach the antenna flex cable from its connector, ensuring the opening pick secures the connector's housing.
• Re-establishing this connection presents a challenge; simplify the process by utilizing tweezers to position the flex cable, ensuring the connector aligns precisely with its socket. Subsequently, apply even pressure directly downward on the connector's face with the spudger's flat edge until a distinct click confirms secure engagement.

• Disconnect the Wi-Fi diversity antenna from its connection.

• To detach the Taptic Engine, first, eliminate the two screws that hold it in place.
  A 2.1 mm Phillips head screw is required.
  Also present is a 2.1 mm standoff screw.
• Employing a standoff screwdriver or bit is the preferred method for removing standoff screws.
• If a standoff screwdriver isn't available, a small flathead screwdriver can be utilized as a substitute; however, exercise heightened care to prevent slippage and potential harm to nearby parts.

Employ the tip of a spudger to carefully separate the antenna cable socket from the connector situated directly beneath it.

Carefully leverage the tip of a spudger to release and detach the Taptic Engine flex cable from its connector.

• Detach the Taptic Engine component.
  Exercise caution when disconnecting the Taptic Engine flex cable, as adhesive may secure it to the antenna flex cable.

• Four strips of stretch-release adhesive hold the iPhone's battery in place, with two positioned at the upper edge and two at the lower edge.
• A small, black pull-tab, weakly attached to the battery's front face, is present on each adhesive strip to facilitate removal.

• Carefully separate the initial battery adhesive layer from the battery's lower right corner.
  Employing fingernails or non-pointed tweezers is preferable for this task; avoid utilizing sharp implements that could damage the battery.

• To ensure successful removal, maintain the flatness and avoid any creases or twists in the adhesive strips throughout this step; otherwise, they are prone to tearing rather than detaching smoothly.
  Furthermore, refrain from applying downward force on the battery while extracting the strips, as this generates concentrated stress that can cause them to catch and fracture.
• Extract one battery adhesive tab gradually, directing its movement away from the battery and towards the lower portion of the iPhone’s chassis.
  Apply consistent, even force while pulling, preserving a constant tension on the strip until it disengages from the space between the battery and the rear casing; achieving optimal results involves pulling the strip at the shallowest possible angle, preventing contact with other iPhone components.
• Expect the strip to elongate significantly, extending to multiple times its initial size; persist in pulling and reposition your grip closer to the battery as needed.
  Should any of the battery adhesive tabs fracture during the removal process, utilize your fingers or blunt tweezers to recover the detached adhesive fragments, and then resume pulling.
  In the event that adhesive strips break off and remain trapped beneath the battery, making retrieval impossible, attempt to remove the remaining strips and then follow the subsequent instructions.

• To completely detach the battery, duplicate the preceding procedure for the remaining three adhesive strips.
  Maintain a firm grip on the battery during the removal of the last strip to prevent it from being ejected from the iPhone with force.
  Should you manage to remove every adhesive strip without incident, proceed to bypass the subsequent instruction.
  Should any fragments of adhesive strips remain adhered to the battery and be inaccessible for removal, proceed with the following instructions.

• Should any of the adhesive strips detach and the battery persist in being adhered to the rear case, introduce a small quantity of isopropyl alcohol (with a concentration of 90% or higher) beneath the battery, specifically near the area of the detached strip(s). Allow approximately one minute for the alcohol to take effect, then carefully elevate the battery.
• Avoid applying excessive force to dislodge the battery; instead, if necessary, introduce additional drops of alcohol to further reduce the adhesive's strength. Under no circumstances should you puncture or warp the battery with your pry tool.
• Exercise utmost care when employing pry tools to remove the battery from the iPhone, as doing so carries the risk of damaging the delicate ribbon cables or the wireless charging coil located directly beneath the battery.
• Should the battery continue to adhere to the rear case, utilize an iOpener or a hair dryer to apply heat to the rear case's surface, positioned directly behind the battery. This process will help to soften the adhesive bond.
• Continue heating the iPhone until the rear case reaches a temperature that is slightly uncomfortable to touch. Prevent overheating, as this could potentially trigger a battery ignition.
• As an alternative method, insert a durable string (such as dental floss or a slender length of guitar string) beneath the battery's edge.
• Employ a sawing motion, drawing the string horizontally across the battery's entire length, to sever the adhesive connection. Ensure that the battery is not deformed or damaged during this process.
• For personal safety and to prevent injury, it is recommended to wear protective gloves or secure the string ends to a tool, such as the handles of two screwdrivers, as depicted in the provided image.

• Disconnect the power source by removing the iPhone's battery.
• Should your new battery be encased in a plastic covering, carefully slide it off and discard it prior to beginning the installation process.
• Ensure complete evaporation of any residual cleaning alcohol within the device's interior, either through careful wiping or allowing it to naturally dry, before proceeding with battery installation.
• Should your replacement battery lack pre-applied adhesive, consult this instructional guide for instructions on replacing the adhesive strips.
• Following the reassembly of the device, execute a forced restart to proactively mitigate potential problems and streamline any necessary troubleshooting steps.
