A Google study and the experience of the editors of the w3bsit3-dns.com portal confirmed that using the dark theme on Android smartphones saves battery power. Ferra informs about this.

A Google study, as Ferra writes, showed that the dark theme on smartphones with an OLED screen can save between 15% and 63% of battery power. However, in the case of devices with IPS matrices, the dark theme does not have any effect in terms of energy efficiency.

Scientists have also tried to confirm or disprove the myth of the benefits of the dark theme for the battery. For example, researchers at Purdue University (USA) found that the dark theme saves battery power only when the backlight brightness is above 50%. Otherwise, the efficiency drops to 3%.

The experience of the editors of the 4PDA website with the Vivo V21 smartphone with an OLED screen has shown that the dark theme is most effective at maximum brightness. The difference is also affected by the application using the dark theme. For example, in the case of YouTube, journalists managed to reduce energy consumption by more than half.
