A test on iOS 13 shows that the Dark Mode feature on iPhones significantly increases battery life. iPhone with OLED display saves significant amounts in dark mode.

With the release of iOS 13 last month, iPhone users finally got Dark Mode. Tests have proven that enabling dark mode on Apple’s mobile operating system extends the battery life of OLED-screen iPhones.

Activating Dark mode changes the iPhone’s interface with a darker theme. iPhone owners can choose to turn the feature on or off at certain times of the day.

A test by PhoneBuff shows that iPhone users with iOS 13 must enable Dark Mode on their device. At the end of the test, the dark mode significantly increases battery life.

The test uses an iPhone XS at full charge and a robotic arm that operates continuously on the phone. The robotic arm performs many tasks, including writing text in the Messages app, browsing Twitter, playing videos on YouTube, and accessing Google Maps. The light and dark mode are tested separately during use.

The results are truly amazing. As soon as the charge of the iPhone XS in bright mode is over, the charge of the iPhone XS in Dark Mode is at 30%. The test was carried out on both displays with a brightness of 200 nits, with different results at different brightness levels. However, it is true that dark mode significantly affects battery life.

The black color on OLED displays is provided by not energizing the pixels. Battery efficiency increases as more pixels are disabled in Dark Mode. On the other hand, the LCD screen devices such as the iPhone 11 do not benefit from longer battery life, as dark pixels are lighter. For iPhones upgraded to iOS 13, Dark Mode can be enabled in the Display and Brightness section of the Settings menu.

iPhone models with OLED display can be listed as iPhone X, iPhone Xs, iPhone Xs Max, iPhone 11 Pro, and iPhone 11 Pro Max. See the test video below to see how much Dark Mode saves power.
