Darker wallpapers vs lighter wallpapers and battery life

[Benz63amg]

So i remember reading a while back that the type of wallpaper that is used on the iPhone can impact the battery life either for the better or worse depending on if the wallpaper has a lot of black pixels or the opposite such as many whites pixels that way the screen needs to light up more parts of the screen etc and I wanted to ask if there's any truth to that, I can't find the link to the discussion I read that time

And just for the record, the wallpaper is a still wallpaper, not dynamic.

So does do the color composition of the wallpaper that we use can affect battry life? Are darker wallpaper better to use less battery life or perhaps it's the opposite and light wallpapers with many whites use less battery life, Can anyone clear this subject up?

Dark is better. A static image is optimum.

Does not matter for LCDs, only matters for OLED screens.

As far as battery life goes that is basically what matters. In the case of iPhones and iPads (so far) LCD is used so lighter vs darker colors don't really affect battery usage.
