If you don't have a smart car, you should disable this core Android app

We all know the familiar, sinking feeling of watching our phone battery dip into the dreaded red zone before the day is even halfway done. If you have ever wondered why your phone battery drains even when you're not using it, it is easy to assume the worst. While we often blame power-hungry video streaming or a brilliantly bright display, the real culprit might be hiding in plain sight — or rather, running in the background. If you drive an older vehicle without a built-in smart infotainment system, or if you commute by public transit, a core system app is likely wasting your battery life.
