Be careful for the short screen ribbon connector at the "top" of the glass panel. Use glass suction handle, lift the screen from the bottom. It is held in place with clips which offer no resistance once pulled free.

The ribbon connector is a flat press connector, it may disconnect if the screen is pulled too far.

Remove 4 screws, the coax for antenna, external button small press connector, battery is a small press connector. The Headphone socket has rubber glue holding it to the case, it can be cut with a knife to release it.

Deal with glue, remove four philips screws, tilt the board out from the top, being careful about the USB-C connector which protrudes into the case.

All parts are now exposed. The battery appears to be glued in place.
