Dark Mode on the iPhone can save massive amounts of battery life, test shows
If you're sick of hearing about dark mode on smartphone apps, I hear you. Now that both Android and iOS have the option to turn your interface darker, not a day goes by without this or that app adding support for dark mode.
But beyond aesthetics, there's a real-world reason to turn on dark mode: increased battery life. According to a recent test, conducted by PhoneBuff , switching to dark mode can extend your iPhone's battery life by 30 percent.
In the test, identical tasks were performed on an iPhone XS Max in Twitter, YouTube, Message, and other apps, first with the phone running light mode, and then with dark mode on.
