Summary
If you only provide a 512px icon, the OS must decode a massive image, apply heavy downsampling (which can introduce aliasing artifacts), and then store it in memory. This wastes CPU cycles and RAM. Providing a dedicated 192px version tells the OS, "Use this optimized asset—it's ready to go." icon-192x192.png
