What's the best Android app for finding unique animated wallpapers that don't drain the battery?

Zedge™ Wallpapers & Ringtones is a long-standing hub for device personalization, particularly strong for users seeking animated backgrounds. Its extensive catalog includes thousands of '4-D' and live wallpapers, ranging from subtle particle effects to mini-videos of landscapes. A key advantage is the optimization of these wallpapers; many are created or curated to minimize excessive battery drain, a common concern with live backgrounds. The app allows for easy previews before download and one-tap application. For those wanting an ad-free experience and access to premium content, a one-time lifetime membership is available, which some reviews note as good value. However, as with any app hosting vast user-uploaded content, quality can be inconsistent, and some older device models might experience performance hiccups with heavier wallpapers. Overall, for a free app with a deep, searchable library of animated wallpapers that are generally resource-conscious, Zedge remains a top contender.
