The PlayStation 5 might be here, but the PlayStation 4 still overshadows it with the quantity and quality of its video game library. Unfortunately, the DualShock 4 controller’s sealed, non-replaceable battery is the weakest link in the aging console. Most PS4 owners discard their controllers once the battery refuses to hold a charge. Although Sony expects you to fork out cash for a new one, it’s cheaper to replace the battery for a fraction of the cost. Here’s how you can do just that. Making Sure It’s a Battery Issue Testing for known DualShock 4 controller issues beforehand will save you the trouble and expense of replacing a perfectly fine battery. Resetting the controller to the factory defaults is a good start. That involves pressing the reset button hidden alongside the screw located next to the L2 analog trigger. The button can be accessed by poking a toothpick through the tiny hole. Depress and hold the tactile switch for ten seconds before releasing it again. Related:
