To begin detaching the battery dock, unscrew the 4 black screws on each corner of the phone with the T5 Torx Screwdriver.

Lift up the battery dock where the hinges are located. Carefully insert the T5 Torx Screwdriver in between the battery dock and the back plate of the battery. (See the picture to locate the hinges)

Remove the battery dock by popping it up with The Spudger.
