The DualShock 4 is generally regarded to be a pretty nifty piece of tech. However, some have voiced concerns that the controller's persistently operational light bar may be affecting its battery life. Luckily, a recent firmware update allows you to dim the contentious luminescence. Which begs the question: exactly how much difference does this new option make?

Well, the crew over at DualShockers did a bit of good old fashioned science, and their results were intriguing to say the least. They found that on the standard setting, the input device lasted around 11 hours, while on the 'medium' option, it lasted 11 hours and 42 minutes. Interestingly, on the dimmest possible brightness, the DualShock 4 lasted 12 hours and 21 minutes.

Obviously, these aren't mammoth differences, but it is nice that the Japanese giant is now giving us the option. Which setting have you had your controller on? Does this result surprise you? Go wild in the comments section below.
