There is a lot of debate on whether or not the red light on the PS4 controller when charging is real or just a marketing ploy. Some people believe that it’s just a way to make sure that you’re not using the controller while it’s charging, while others think that it could be a sign of something more sinister. There is no definitive answer, but we do know that some people have had trouble with their controllers turning off when they’re plugged in, so it’s worth checking out if your PS4 has this issue.
