Dark mode saves your phone’s battery life: Study

It has been found in a study that enabling dark mode on your phone can increase its battery life, but there’s a catch. In the Purdue study, researchers looked at dark mode power usage from six different applications - Calculator, google Calendar, google Maps, google News, google Phone, and Youtube. these applications were tested on a Pixel 2, Pixel 4, Moto Z3, and a Pixel 5 — all phones with OLED screens. the researchers, when running each of

these apps in dark mode for 60 seconds, tested the power draw. they said that they built a set of tools to accurately measure power draw in pixels. at around 30 to 50 per cent brightness, the researchers found that switching from light mode to dark mode only saved between 3 per cent and 9 per cent power on average. However, switching the other way around at 100 per cent brightness can save as much as an average of 47 per cent battery power.
