Does the dark mode in phones with LCD and OLED screens save battery?
So when you enable dark mode on a device with an OLED display, whether it's a phone, tablet or watch, whenever the background or parts of it are completely black, the device has to light up a relatively smaller number of pixels. As a result, it consumes less energy and your device's battery lasts longer, but it does not make any difference in battery consumption in LCD displays.
