New Study Says Dark Mode Doesn'T Do Much For Battery Life - Light Home News

There was a time when consumers demanded dark mode for all apps and devices. Now that most of them already have this option, researchers are reexamining it to see if it has any real benefits, especially for a device’s battery life. New study says specific scenarios when dark mode is on won’t really give you much efficiency and battery life gain despite what people initially thought.

Android Authority Shares a study by researchers at Purdue University that shows that going dark doesn’t really make a big difference in power consumption. Well, it’s actually in pretty specific but typical use. Most people use automatic brightness settings indoors with around 30-40% brightness. So switching from these settings to dark mode will only save you 3-9% on average. Logically, the energy savings will increase if you switch from bright mode with 100% brightness to dark mode, thus saving you 39-47% of your juice.

The study tested six apps – Calculator, Google Calendar, Google Maps, Google News, Google Phone, and YouTube – and tested them on Pixel 2, Pixel 4, Pixel 5, and Moto Z3. They used a tool they developed called Per-Frame OLED Power Profiler (PFOP) which saw how dark mode affected one minute of activity for each of the apps. The study also indicated that Android’s battery consumption feature does not take dark mode into account when calculating an app’s power consumption.

While the results seem logical, it’s interesting how much you actually save on your battery consumption when switching from low to medium mode to dark mode. But it would also be interesting to note if battery saving is actually a major reason for users to go into dark mode. Some would just prefer to use the dark mode for brightness or aesthetic reasons rather than for energy saving reasons.

Android Authority says it might also be interesting to see the test use brightness metering for each device, as some devices have brighter screens. Either way, we might see more studies on Dark Mode, as it’s almost a common feature for apps and devices these days.
