Use this guide to replace the 3.7 lithium-ion battery inside the DualShock 4.
Step 1 Controller
Using the Phillips #00 Screwdriver, remove the four 6.0 mm screws securing the rear cover to the controller.

Wedge a plastic opening tool into the opening and slide it up towards the joystick.
Pull down on the plier to crack open the casing.
Repeat these steps for the right shoulder.

Wedge a plastic opening tool into the case-splittings and pull down to crack open the casing near the following buttons:
Split the plastic covers of the controller apart, taking note that they will still be attached by circuit board ribbons.

Step 5
Using the blunt forceps, remove the battery plug by gently rocking the forceps side-by-side to loosen the plug.

Hasty removal of the battery plug could warp the plastic grips of the plug.
