    Does "Screen Filter" app actually reduce brightness to help with battery life?

    I have this app installed and it works great on my phone. Sometimes the minimum brightness settings is still too bright. This app makes your screen much much dimmer, based on the levels you choose. But I'm wondering, is it actually dimming the screen more, or is it merely applying a 'shade' over your screen while still maintaining the preset brightness? And if it's just a shade, would this help with battery life?

    interesting...

    Yeah the lowest level of brightness is still quite bright.

    "
    It even saves battery life for AMOLED displays!" so they claim...

    Yeah that's what confuses me. You can literally make the screen so dim you can't even see anything, but I'm not sure if the screen is actually consuming less power, because the system settings haven't changed...?

    Maybe it takes away from the power to the screen? If it literally just adds a shade I don't see how that saves battery life

    How much phone battery can you save by switching to dark wallpapers and themes? | SHIFT_beep according to this on super amoled screens such as the galaxy nexus' it takes less power to create a dark pixel that a light one. Therefore essentially saving battery life even if the app is "shading" the screen. Unfortunately i wouldn't expect too huge of a difference.

    Its a shade that sits on top. What annoys me is that it doesn't have an option to dim the sofkeys, but there are ways around it. Logically, It should help with battery life, I mean, you do lower the brightness of your screen to conserve power. Its not the setting, its the fact that it takes less power to light up a super dim pixel than dim or bright ones.
