PSA: LA Noire - Right Joycon Battery Drain
Just a quick PSA of sorts here for you guys.
LA Noire uses the infrared sensor on the right Joycon at all times. Tapping the sensor will reload your weapon.
Unfortunately, there doesn't appear to be a way to disable this feature, and because of that, the right joycon battery drains at roughly double the speed.
Hopefully Rockstar fixes this issue in a future patch.
