The heart of the smartphone interface may not maintain the battery power after all.
Although the long beliefs indicate that the “dark situation” extends the battery life-especially on the phones equipped with OLED screens to save energy-I found a new study from the BBC that most users are compensated by pushing the levels Energy gains.
According to the research, 80 percent of the participants who converted their phones into a dark background, then modified the brightness up, caused their batteries to drain a faster rate. On the contrary, those who choose the standard “light mode” was less likely to be attracted with screen settings, which means that the original lower brightness has been preserved.
This dynamic conflicts with the previous laboratory -based results, including the study of Bordeaux 2021 University, which turns out that phones that were set on the dark situation use 42 percent less energy under full brightness conditions. Likewise, Google engineers have discovered a potential decrease in energy by up to 63 percent for OLED screens in the dark mode. However, these tests were not treated in the behavior of the user in the real world.
Zak Datson, engineer in the BBC research and development team, said that simple sustainability tips do not always stand to scrutinize actual practice. “Some of the most common recommendations are very simplified,” he pointed out. “In the case of dark mode, some people end up using more energy.”
The BBC test confirms that the best way to prolong the battery life is to reduce the brightness of the screen. Reducing brightness can lead in half energy consumption compared to the phone preserved in the maximum settings.
The study is part of the BBC's broader sustainability campaign, as the company aims to reduce total carbon emissions by 90 percent by 2050. Among the carbon sources associated with the media, the production of devices such as television and smartphones ranks as the main rank as a major shareholder, While in the production of films, travel is usually the largest carbon emitter.
