Get Pixel Filter to save battery power
As screens get bigger and with battery life always at a premium, even AMOLED screens can use a little help.
AMOLED (active-matrix organic light emitting diode) screens are inside a wide variety of phones, from the original Moto X to the latest Samsung Galaxy 8, 8+ and Note8. AMOLED differs from LCD in that each pixel is its own light source. With traditional LCD screens, the pixels need to be lit from behind. Counterintuitively, in LCD, pixels are backlit even when they’re trying to show black.
If you’re wondering whether your phone has an AMOLED display or not, check out this handy Wikipedia list (just click Show to expand the list).
AMOLED screens are capable of showing off a greater range of colors and displaying vibrant images. One cool thing about AMOLED is that when a pixel is black, it’s off and so doesn’t draw power.
Maybe you’re already dimming your screen when your battery starts to run low but that’s only part of the battle. Pixel Filter is a smart little app that lets you take things a step further. Download it for free in the Google Play Store.
