Smartphones tout 'dark mode' as an energy-saving feature, because darker-colored pixels use less power than lighter-colored pixels.
It's mostly an intellectual placebo, finds a new study,
because of the way most people use their phones on a daily basis. The study looked at six of the most-downloaded apps on Google Play: Google Maps, Google News, Google Phone, Google Calendar, YouTube and Calculator. The researchers analyzed how dark mode affects 60 seconds of activity within each of these apps on the Pixel 2, Moto Z3, Pixel 4 and Pixel 5.
