More battery life for mobile phones: study reveals great trick

For many smartphone users, battery life is a decisive factor when buying a new model. So you need a large battery, which is often found in more expensive cell phones. However, how you use your smartphone also has a not insignificant influence on the running time – a great trick can help.

This is how you get more battery power out of your cell phone

The battery trick that American researchers have now proven in a study is very simple – at least once you have figured it out: With some smartphones you can save quite a bit of energy, by using the dark mode. But the trick doesn’t work with all cell phones.

According to the researchers, you have a good chance of being able to use the trick if your smartphone is not older than it was in 2017 (source: ACM Digital Library via Purdue University). Then newer cell phones use OLED displays more often and only with these the experts at Purdue University could prove that the “dark mode” saves the battery under certain circumstances. Because the light intensity of the individual light points can be individually controlled in OLED displays, a mostly dark or black screen requires less energy.

And this is how it works: You can find the dark mode under Android in the settings under the menu item “Display & Brightness”. Incidentally, you will achieve the greatest savings by switching to higher display brightness. At 100 percent luminosity, the energy requirements of the display decreased in the apps tested, such as YouTube and Google News by 39 to 47 percent. If you let your smartphone regulate the brightness yourself as required, the effect should be significantly lower and be in the single-digit percentage range. You can also use other tricks to save your cell phone battery.

Whether Android or iOS: Dark mode helps power consumption

For the study, the researchers only used Android smartphones.
