do extra dim save battery

Extra dimming can help save battery life on devices with OLED (Organic Light-Emitting Diode) displays such as smartphones and certain televisions. When you lower the brightness or dim the display, less power is consumed by the screen, resulting in longer battery life. However, it is important to note that extra dimming can also affect visibility, and you may find it difficult to see the content on the screen in brightly lit environments or in direct sunlight.
