Dark Mode really does save your phone's battery life, says Google

  1. As reported by SlashGear, Google did spend time going over some of the more obvious points, such as the brighter a phone, the more power it will draw.

    What’s interesting is the comparison between the original Pixel, which uses an OLED screen, and the LCD-sporting iPhone 7. Google’s device draws 250mA while at maximum brightness in normal mode, while Apple’s phone was at 230mA. In Night Mode at max brightness, however, the Pixel’s draw drops 63 percent to 92mA, while the iPhone stays the same.

    With OLEDs, pixels are essentially turned off when displaying the color black, whereas LCDs keep their pixels lit up no matter what is being shown on the screen. So, it stands to reason that the mostly black Night Mode will help conserve your OLED handset’s battery life.

    Another chart compared the power draws of different colors while at maximum brightness. Unsurprisingly, black is the lowest, while white, which is featured prominently across Google’s apps and the Android OS, has the highest draw. The company acknowledged that white is “less than ideal.”

    Google showed the difference Dark Mode makes in its YouTube app. At full brightness, power draw dropped by 60 percent when moving from normal to dark.

    Google has released Dark Mode for apps such as YouTube, Messages, Google News, and Phone, and we can expect it to arrive for more apps in the future. Even if you’re not a fan of Dark Mode, it’s an effective way of keeping your OLED phone working longer.

    Water isn't wet. Water wets things, but water itself cannot be wet.

    Hahaha, that is wrong in terms of screens. The problem is that you're either assuming all types of screens are made the same or that everyone knows that they aren't.

    This reminds me of the Mythbusters episode where they did the one about leaving the light on saves energy versus turning the light off when you leave a room. Of course turning it off saves more energy. Another duuuuuh.

    The advantage of the OLED/AMOLED screens.

    If only there is a cheaper future iteration of the IPS that can turn off black pixels....

    This is good news...As Google making night/dark mode available for apps and android, Apple could do the same for iOS and iPhone apps....

    Apple will invent it shortly after. Revolutionary!
