So you're deeply absorbed into the lore of your game of choice. For example, let's say you're playing a episodic story series such as Life is Strange. You're watching an emotional scene play out in front of you when you hear an alert.
Your eyes can't help but to avert to the top-right corner of your screen to see "low battery warning." The gripping emotional drama must wait while you slide your butt over to your PS4 to plug in the charge cable. Also, I hope you like the floor because that cable won't reach your sofa.
