Much is said about the dark mode, it is the simple fact of changing the white tones to black, and it is that the visual fatigue to which we are subjected after long hours in front of the screens of our mobile phones make us look for alternatives to visualization standard of it. As if it were a next-generation technological innovation, the public applauded the launch of a "dark mode" in iOS 13. However, One of the most widespread theories in recent months is that using dark mode saves battery life, a test has just confirmed this.
Neither low consumption mode, nor lowering the brightness to exhaustion (of these users one day we will make a separate post), nor deactivating WiFi and Bluetooth, what really saves battery on an iPhone is to use the new dark mode, regardless Whether it is day or night, very early or very late, it is officially proven that using dark mode throughout the day saves battery, and this is news that those users who live permanently hooked on the cable will be very pleased Lightning, but ... How much battery is really saved with dark mode? Let's see the test that the boys of PhoneBuff on his YouTube channel:
We have to make a point, not all devices save battery using dark mode, those where we are going to have a real improvement are those that use OLED screens, and is that with this technology the black pixels are off pixels, hence the "battery saving" when using the dark mode. These terminals are: iPhone X, iPhone XS and iPhone 11 Pro in its different variants (Max or normal). So from here I recommend that if you have an iPhone with an LCD screen like the iPhone 11, you enjoy it and its enormous autonomy without worrying too much about dark mode. Be that as it may, You can gain up to 30% autonomy using this "peculiar" technique.
