Dark modes, now available on most operating systems, aim to save power by making most backgrounds very dark or black, while also gratifying those who just prefer the look.<\/p>\n<p>But what about on the older but still dominant screen technology, LCDs? The BBC is out with <a href=\"https:\/\/www.sicsa.ac.uk\/wp-content\/uploads\/2024\/11\/LOCO2024_paper_12.pdf\">a small, interesting study<\/a> comparing the light and dark modes of one of its website pages on an older laptop. Faced with a dark mode version, most people turned up the brightness a notable amount, sometimes drawing more power than on light mode.<\/p>\n<p>It&#8217;s not a surprise that dark modes don&#8217;t do anything to reduce LCD power draw. However, the study\u2014not peer-reviewed but published as part of the <a href=\"https:\/\/www.sicsa.ac.uk\/loco\/loco2024\/\">International Workshop on Low Carbon Computing<\/a>\u2014suggests that claims about dark mode&#8217;s efficiency may be overstated in real-world scenarios, with non-cutting-edge hardware and humans at the controls.<\/p>\n<p><a href=\"https:\/\/arstechnica.com\/gadgets\/2025\/02\/small-study-suggests-dark-mode-doesnt-save-much-power-for-very-human-reasons\/\">Read full article<\/a><\/p>\n<p><a href=\"https:\/\/arstechnica.com\/gadgets\/2025\/02\/small-study-suggests-dark-mode-doesnt-save-much-power-for-very-human-reasons\/#comments\">Comments<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>If you know how OLED displays work, you know about one of their greatest strengths: Individual pixels can be shut off, offering deeper blacks and power savings.
