- Disconnect the Battery: Once the screen is open, locate the battery connector and unscrew the metal cover. Gently lift the connector using a plastic spudger to disconnect the battery from the motherboard, ensuring you do this delicately to avoid damaging the connectors.
- Remove the Old Battery: The old battery may be secured with adhesive strips. Carefully pull these strips to remove the battery, or use the spudger if necessary. Take your time with this step to avoid damaging the surrounding components.
- Install the New Battery: Place the new battery into the compartment and connect it to the motherboard. Ensure that the connector is firmly attached and that the battery is seated correctly in its place.
- Reassemble the iPhone: After the new battery is installed, carefully reposition the screen and reconnect any cables that were detached. Secure the screen back in place using the screws you removed earlier, ensuring everything is aligned properly.
