PS4 controller is one of my favorite controllers, like any other PS controller out there. But DualShock 4 has a short battery life, and some of you may find annoying this thing. Here is a trick on how to fix battery life problems of DS4.
The problem is the battery, is only 1.000 mAh. On eBay there is a seller who sells very cheap batteries at 2.000 mAh for only $4.32.
This battery is very similar with the original one, has the same size and connections, so the installation is very easy. You only have to open the controller, take out the original battery and insert the new one. Then, connect your controller on PS4, to fully charge the battery to its maximum.
A USB cable is also included in the package.
