Indeed, I always try to keep it in energy saving mode by having it bottom side up in my pocket. But when I want to listen to music too, I have to orient my phone the other way because of the headphone jack, which causes the screen to stay on. Since my smartphone is a few years old, the battery doesn't last very long that way. Quite annoying.
