    Has anyone noticed an appreciable difference in battery with parallax on vs. off? Do most have it on or off for daily usage?
    I am going to test it myself with a day on, day off, etc. to see what happens. I was just wondering what the general consensus is about parallax and battery drain.

    I tried it early on and didn't notice a huge difference at the time.

    Slightly related topic but I'm curious about the Dynamic wallpapers though because those DID seem to drink the battery juice pretty heavily in beta 1 and 2.

    I've heard the parallax doesn't take to much more battery because it uses the accelerometers that are always on anyway. But I haven't tested it.

    I want to know this as well. For what it's worth, on my iPhone 4S, disabling Parallax, Frequent Locations, Background App Refresh, Transparency, and Dynamic Wallpapers gave me as good battery life as, if not better than, iOS 6.

    Turning all those back on killed my phone by the end of the day (whereas I'd have ~50% left in the aforementioned scenario) and also made the UI laggy as hell.

    I haven't focused much on Parallax individually but I think I noticed that it caused more UI lag than battery drain on my phone. What really killed my battery was Frequent Locations and Background App Refresh. Transparency, Dynamic Wallpapers, and Parallax made my animations stutter a ton more than anything but I'm sure the GPU usage required for those features also contributed to battery drain.

    Hopefully this is all fixed with iOS 7 on the iPhone 5S and those that are upgrading to it can take advantage of all of those features without battery drain or lag.
