Who has never taken their cell phone at night and, when they called, was struck by that blinding glow? Well, the night mode is an interface version developed so that the brightness of the screen does not obscure our vision so much and we can continue using the device without suffering.

With predominantly darker tones and some lighter highlights, the night mode not only brings greater visual comfort, but also helps to save more battery in devices with OLED or AMOLED screen. As in the case of these devices, the pixels have their own lighting, when the information is black, the pixel remains off.
