Using Dark Mode Will Save Battery Life

This myth is somewhat true, but it depends on which iPhone or smartphone you use. Dark Mode can save some battery life, but only if your device has an OLED display.

This is because OLED displays handle darker images better. To be more specific, an OLED display will reduce power consumption or completely turn off the pixels when there is a darker or black color on the screen. Since your iPhone will need less power to show darker images, you will see an increase in battery life.

Of course, as we mentioned before, your device will need an OLED display for this to work. The iPhone 12 and newer models all come with OLED displays. Older iPhones won’t see a difference in battery life when using Dark Mode, but we still think it’s the sleeker option.

To turn on Dark Mode on your iPhone, go to Settings > Display & Brightness and tap on Dark.
