Justification for Light Bar existence; Not whether it should have on/off toggle

[Jizz_Beard_thePirate]

I am curious, does the light thing take up extra battery power or not? Like, if you didn't have the light thing on all the time, would you get like 1hr+ more of gaming out of the controller or is it like only 10 minutes more? Cause if its only 10 minutes more, than sure, its worth it but if its 1hr+ more than I don't think its worth it from my perspective so if someone has the answer, please tell

I guess my personal issue with not being able to turn it off is that when I go to my friends house, he has a Cat and everytime I go to his house and play the ps4, the Cat thinks the Light means playtime and it always tries to catch the controller and its very annoying when I am playing any game cause it will not stop jumping on to my lap/head/sofa until it catches it multiple times. Sure, its not an issue for most people but it is an issue for me
