Hey guys, I just downloaded the mystic halo live wallpaper and love it! However, I am worried about it effecting the life of my phone. I have a galaxy nexus with jelly bean so I can finally run live wallpapers with zero lag. What I am worried about is since the wallpaper is always running will this constantly put strain on the cpu and gpu over time if I keep it on for good? Does the wallpaper actually stop when the screen is off or when I am in another application and not on the homescreen? I'm sure the battery takes a hit but so far I haven't noticed a difference. Please help. Thanks!
