Step 16 | Loosen the battery
Carefully align the 4mm hex key to the setscrew and tighten it to a torque of 1.5 Nm using the torque wrench.
- Carefully lift the battery away from the rear case using a spudger, as it is secured by an adhesive strip that runs along its edges.
- Employing solely the provided plastic pull-tab to detach the battery risks causing deformation; therefore, avoid this practice.
- Disconnecting the battery isn't required to replace the GPS antenna; however, doing so provides greater clearance when removing the headphone assembly, a step that isn't essential for the antenna replacement itself.
- The iPhone battery is secured to the rear enclosure using a low-strength adhesive, which typically remains adhered to the battery during removal. If your new battery has pre-applied adhesive, no further action is needed; otherwise, carefully move the adhesive from the original battery to the replacement.
- To release a battery that is sticking to the back cover, carefully introduce a small amount of isopropyl alcohol with a concentration exceeding 90% between the battery's edge and the case. Permit approximately one minute for the alcohol to dissolve the adhesive bond, then use the spudger's flat end to delicately pry the battery loose. Ensure the alcohol completely evaporates before proceeding with the new battery installation.
- To prevent damage, avoid using excessive force when removing the battery. Should the battery remain difficult to dislodge, add additional alcohol drops to dissolve the adhesive. Ensure the pry tool does not compromise the battery's structural integrity by bending or puncturing it.
- To facilitate battery separation, apply gentle heat to the case's rear surface using a hair dryer or heat gun, ensuring the setting is at its lowest level; this softens the adhesive securing the battery.
- To prevent battery ignition, avoid exposing the iPhone to excessive heat.
Step 17 | Headphone Jack
Carefully align the 4mm hex key to the setscrew, ensuring it engages fully, then tighten the setscrew to a torque of 1.5 Nm using the torque wrench.
- Using a Phillips #00 screwdriver, detach the on/off switch from the front bezel by unscrewing the two screws that hold it in place.
- Verify the switch's extension during replacement; a thin plastic spacer is affixed inside the button and could detach during cleaning. Absence of this spacer may result in insufficient button projection for proper operation, so if it's missing, substitute with a piece of rigid plastic approximately the same thickness—such as material from a shirt box lid—to compensate.
Step 18
