LED and AMOLED screens are admired by screen junkies all over the word because they produce the deepest blacks in a mobile device display. This is because LED screens, including Samsung’s more preferred AMOLED screens, just basically turn off when they’re assigned to draw the “black” color. That’s what the new app “Pixel OFF” tries to do, because theoretically, LED pixels not emitting light draws no electrical power.


So, in theory, an LED or AMOLED screen with more black draws less power than those that show more color. That is where Pixel OFF tries to help you save battery power – it overlays a layer of evenly-spaced black pixels on your screen, theoretically lowering the display’s power consumption, thereby saving the user battery life.

Mind you, on LED and AMOLED screens can benefit from this, if ever. LCD screens can’t claim the same benefit because of a different way of “drawing” the black color on screen. The app has received some good feedback, and it requires no root at all, so it’s an easy install. Our question is, what is the difference between applying the app and say, just manually lowering brightness?

The app is free to pick up at the Google Play Store (source link below), but it has an IAP that allows you to unlock more noticeable or less noticeable overlays. You can also set the app to trigger when your battery reaches a certain level. Our suggestion is this – study the app’s capabilities and tell us about it.
