Happy to be proven wrong, but at a guess this surely makes close to no real difference to battery life in reality? Who unlocks their phone and just stares at the wallpaper behind their icons? I suspect most users are only briefly on their home screens before doing something productive, like, you know, actually using an application, in which case the power savings afforded by this would likely be negligible at best.

I often use my phone mostly for looking at the bus time widget. So the wallpaper and the wallpaper background of the widget does make a difference (admittedly small difference). Note that the app can be used not just for oledifying wallpapers - you can edit wallpapers on it too and crop/resize them for your different screen sizes etc. The main reason I built this was for the crisp true blacks and then from the research, I found it might make a small difference in battery life too.
