Traditionally "burn-in" means that the afterimage (a ghostly "impression" of the image that was on the screen previously) never goes away; it's permanently burned into the screen. Image retention, on the other hand, implies something temporary, where the afterimage disappears eventually. Whatever you call it, burn-in is generally caused by leaving a static section of screen on for a long time.

You see more static images on phones, particularly the notification and navigation bars.
