iPhone 7 Plus Battery Replacement

• As a preliminary precaution, ensure your iPhone's battery is depleted to a level less than 25%.A lithium-ion battery that retains a charge presents a fire hazard and potential explosion risk if it sustains physical damage.Deactivate the iPhone's power supply prior to commencing the disassembly process.
• Detach the pair of 3.4 mm pentalobe screws located along the iPhone's lower edge, utilizing a P2 screw bit if available.
• Separating the iPhone's display assembly will irreversibly damage its water resistance capabilities; therefore, acquire replacement seals beforehand, or exercise extreme caution to prevent moisture ingress during reassembly if new seals are not used.
• Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

• To avoid potential harm to your device, ensure the opening pick does not extend too deeply; this procedure will help you identify a safe insertion depth.
• Determine the distance of3 mmfrom the pick's leading edge and use a permanent marker to create a visible indication on the opening pick.
• For additional reference, you may also apply markings at other points on the pick, each representing a distinct measurement.
• As another option, 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; should you choose not to utilize this tool, proceed past three steps to an alternative approach.

Detailed instructions regarding the Anti-Clamp's operation can be found in a separate, dedicated guide.

• 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, 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 slick, preventing adequate adhesion by the Anti-Clamp, applying adhesive tape can provide a more textured interface for improved grip.

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

• Apply warmth to aiOpenerand 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, excessive temperatures may compromise the display or internal battery, necessitating cautious operation.
• 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-Clampfail to generate a satisfactory separation, increase the heat applied to the region and rotate the handle by ninety degrees.
• Avoid exceeding a ninety-degree rotation increment, 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 bottom edge of the iPhone facilitates the loosening of the adhesive bonds holding the display in place, which simplifies 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, because overlapping will obstruct the creation of a proper bond between the suction device 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.

Due to the robust, waterproof sealant securing the display, establishing this initial separation requires considerable effort; should you encounter difficulty, applying additional heat and gently oscillating the display upwards and downwards will help to reduce the adhesive's strength, allowing for sufficient separation to accommodate your tool.

• Begin separating the display assembly from the chassis by inserting a prying tool beneath the left edge, initiating the separation at the bottom and progressing upward toward the volume controls and the silent switch, effectively disrupting the adhesive bond.
• Cease the separation process in the vicinity of the upper-left corner of the display.
• Refrain from attempting to dislodge the display's top edge from the rear casing, because it is secured by fragile plastic retaining clips that are susceptible to fracture.

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.

• Utilize three screws, each measuring 1.2 millimeters in length,
• along with a single screw that is 2.6 millimeters in length.

• Employing the tip of a spudger, carefully disengage the battery connector from its corresponding receptacle on the logic board.
• To ensure the phone remains de-energized, gently elevate the connector cable, preventing any electrical connection with the socket.

• Employ the planar edge of a spudger tool, or a fingernail, to release the two lower display connectors; lift them vertically away from their corresponding receptacles on the logic board.
• To secure the connectors during reassembly, apply downward pressure on one terminus until an audible click is heard, then repeat the process on the remaining terminus; avoid applying pressure to the central portion of the connector, as this can induce bending and result in irreversible harm.

• To detach the bracket that covers the connector for the front panel sensor assembly, first eliminate the three screws that use a Y000 tri-point driver.
  
  • A single1.3 millimeterfastener
  • Next, utilize two1.0 millimeterthreaded fasteners
• Subsequently, take the bracket away.

• To prevent damage, detach the connector linking the front panel sensor assembly to the socket located on the logic board.
• To reduce the potential for deformation, ensure this press-fit connector is reattached incrementally, engaging one end before the other.

• Detach the display unit from the device.
• When putting the device back together, halt at this stage should you decide to substitute the adhesive securing the display's perimeter.

• To detach the barometric vent, eliminate the two Phillips screws that hold it in place on the rear case.
• A 2.9-millimeter screw is required for this step.
• Additionally, a 2.1-millimeter screw must be removed.

To release the barometric vent's adhesive bond with the iPhone's lower edge, carefully depress the vent inward, guiding it towards the Taptic Engine.

• Employ the planar edge of a spudgerto separate the Taptic Engine connector from its corresponding receptacle situated on the logic board.

• To detach the Taptic Engine from the rear enclosure, eliminate the three1.5 mm Phillips screwsthat hold it in place.

• Carefully separate the three adhesive layers located along the battery's bottom edge.
• Employing your fingernails or a tool with a rounded, non-sharp tip, such as blunt tweezers, is preferable; however, exercise caution to prevent puncturing the battery with any pointed instruments.

• To prevent adhesion and tearing, ensure the adhesive strips remain smooth and free of creases throughout this repair; folds can cause the strips to bind and fracture rather than detach easily.
• Gradually draw one battery adhesive strip away from the battery, directing its movement towards the lower portion of the iPhone’s chassis.
• Maintain a consistent, even force while extracting the strip until it disengages from the space between the battery and the rear enclosure; achieving optimal results requires pulling the strip at an angle of 60 degrees or less.
• Expect the strip to elongate significantly, extending to multiple times its initial size; if needed, continue the pulling action and reposition your grip closer to the battery to maintain control.

• Replicate the preceding procedure for the remaining two adhesive strips.
• Maintain pressure on the battery during the removal of the last strip to prevent the battery from being ejected from the device's casing upon separation.
• Should all adhesive strips be successfully detached, proceed directly to the subsequent instruction.
• Conversely, should any fragments of adhesive strips remain adhered to the battery and be inaccessible for removal, proceed with the following steps.

• Should any adhesive strips detach and the battery persist in its adherence to the rear case, dislodge it by carefully introducing a small quantity of isopropyl alcohol, with a concentration of 90% or higher, beneath the battery, specifically near the detached strip(s).
• Allow approximately sixty seconds to pass, then cautiously elevate the battery.
• Refrain from inserting your spudger between the volume down (-) button and the battery's upper edge, as this action risks damaging the volume control cable situated beneath.
• Avoid applying force against the logic board, as doing so could result in phone damage.
• Refrain from employing excessive force to dislodge the battery; if necessary, introduce additional drops of alcohol to further reduce the adhesive's strength. Under no circumstances should you deform or puncture the battery with your prying instrument.
• Should the battery continue to adhere to the rear case, utilize an iOpener or apply heat to the rear case directly behind the battery using a hair dryer, ensuring the temperature reaches a point that is slightly too warm for comfortable touch.
• Excessive heating of the iPhone presents a risk of battery ignition.
• Dental floss can be employed to separate the battery from the rear case; a more robust substitute is an unwound guitar string, specifically a 0.009 E string from a 12-string guitar set. Pass the floss or string behind the upper corners of the battery, combine the ends, wrap them around a folded cloth, and exert even tension.

• Disconnect the battery to proceed.
• Should your new battery be packaged within a plastic sleeve, detach it by separating it from the ribbon cable prior to installation.
• Ensure any residual alcohol solution is completely gone from the phone's interior, either by meticulous wiping or allowing it to evaporate fully before the new battery is placed.
• To guarantee correct positioning within its designated space, briefly reconnect the battery connector to the logic board socket before securing the replacement battery in place.
• Once the battery is affixed, detach it from the logic board, and then proceed with the remaining reassembly steps.
• In the event that your replacement battery lacks pre-applied adhesive, consult this guide for instructions on replacing the adhesive strips.
• Following the complete reassembly, execute a forced restart to proactively avoid potential problems and streamline any necessary troubleshooting.
