Locate the solder on the side of the metal plate on the top half of the phone.

Place a piece of solder wick on top of the solder.

To desolder the connection, very carefully place the tip of the soldering iron on top of the solder wick. Hold it steady until the solder is soaked up into the solder wick.

Cut off the used solder wick with pliers and repeat this step if any solder remains.
