iPhone 6/6S/7:

  1. Remove the battery cover.
  2. Remove the screws that hold the phone together (2 on each side).
  3. Pry off the adhesive that holds the phone to the case.
  4. Disconnect all of the cables and connectors from the phone.
  5. Slice off one end of each cable and connector, then cut them in half so they are longitudinally cut (likewise for the other end).
  6. Take one half of each cable and connector, and twist them around a screwdriver or your fingers to make a loop (likewise for the other half). Make sure there is enough slack in both loops to fit through a small hole on top of your iPhone 6/6S/7, and then screw it back on (the screws should now be facing down).
