Use a plastic opening tool to gently pry the battery connector up from its socket on the logic board.

Pry from the top and bottom of the connector bracket—there isn't as much of an overhang on the sides, and you may damage the connector.

Be very careful to only pry up on the battery connector and not the socket on the logic board. If you pry up on the logic board socket, you may break it entirely.

Remove the metal clip covering the antenna connector.
