PS4 Controller LEDs Suck (the battery)

The new Playstation 4 Dualshock controllers are super high-tech. They have bright shiny lights on them to prove it.
But [xn0] from neograf.com had a suspicion about these new-fangled controllers. That LED light bar is awfully bright, how much power does it consume?
As it turns out, quite a bit. After dismantling one of his controllers he discovered the LEDs are connected to the main PCB with a ribbon cable — super easy to detach. He then performed some rather unscientific tests of leaving the controllers on over night. His empirical conclusion? If you leave the controller with lights on it will die within 24 hours, if you disable the lights, it will still be at approximately 66% battery capacity after the same amount of time.
Another user on the forums quickly pointed out that this test could have been as simple as using a multimeter — so he did that afterwards. The LEDs appear to draw around 40-50mA, which isn’t that much, but it is more than the controller uses while idle (30-40mA)!
We assume Sony will add a firmware option to turn these lights off in the future, but until then, if you’re really dying for an extra hour or so of gameplay, it’s a super easy modification.
