#2 Turn Down Lightbar Brightness
With the DualShock 4, Sony added a lightbar function to the controller that not only illuminates a light but can change colors depending on the game or scenario. However, if you wish to prolong your battery life, it may be worth dimming the light within the settings menu. Additionally, because the light is so bright, players may find that it will actually reflect on their television display, giving you all the more reason to dim the brightness.
