Step 3: Heat and Loosen the Screen Adhesive
Place the iPhone face-up on a separator machine and set the temperature to 80°C. Alternatively, use a suction cup and heat gun for manual heating.

Secure the device with clamps and attach a suction cup to the screen.

Once heated, lift the suction cup to create a gap and apply a few drops of ethyl alcohol along the edges to soften the adhesive.



Step 4: Open the Display
Insert an opening pick under the screen’s bezel to separate the adhesive and carefully slide it around the edges.


Place the iPhone in a screen holder or lean the screen against a stable surface. Gently swing the screen up to open the device.

Step 5: Disconnect Display & Battery
Unscrew the display connector bracket using a precision screwdriver and remove the display and antenna brackets with tweezers.


Disconnect the battery, display, and sensor cables using a spudger, then remove the screen assembly.

Remove any remaining adhesive and clean the battery compartment.

Step 7: Prepare and Install the New Battery
Unpack the REPART iPhone 14 Pro replacement battery and attach the provided adhesive strips.



Use a small roller to press the adhesive firmly and fold the edges onto the battery.


Peel off the adhesive release liner, align the battery in the iPhone housing, and connect then disconnect the battery cable to reset the connection.


Roll over the battery with the roller to ensure secure placement.

Step 8: Reassemble the iPhone
Peel off the backing of the new screen adhesive, align it, and press it into the iPhone body.



Use tweezers to peel off the front adhesive liner.
