I know the conventional wisdom is that animated wallpapers are, by their very nature, a drain on your battery. And I can even accept the apparent logic of this. However, I've also read many times that users just don't see that much difference. In fact, my own back-to-back comparisons between a live wallpaper and a stock static wallpaper (my daily use patterns are pretty fixed and predictable) have shown this, too...not much difference.
But what I guess I still don't fully understand is this: is a live wallpaper a drain only when it's running and visible on the screen? If so, that's pretty easy to control....just get to an app, right? Or do live wallpapers somehow put a load on the battery even when they're not on screen? I don't see how it's possible...but do they load the battery when you're using an app? Do they load the battery even when the phone is dark and "idling"? If it's really a case of "they run only when you see them running" then that explains why they really don't add all that much to the drain on your battery.
