When replacing the battery, ensure you have the correct model for your device:
Pre-heating the backside is crucial before removal, as it's primarily bonded with glue.
Note: The red screws are equal length/size, while the blue screws are shorter.
Remove the plate.
Remove the black plate with antenna, now free from surrounding components.
The phone has been rotated by 180 degrees.
Remove the transparent tapes by peeling them off, moving them towards the outside of the phone. Note that these cannot be removed entirely.
Do not attempt to remove the tapes completely, as they are glued to the device.
The green transparent tape should remain in its original position for now.
Replace the battery.
