| Does dark mode reduce phone battery consumption? |
Many users prefer to activate the night mode feature in the smartphone at the operating system or application level, because it does everything much better than the lighting mode, because it is very easy on the eyes, especially when reading, and reduces cell phone battery consumption.
Will dark mode reduce phone battery consumption?
According to a study recently published by Purdue University, researchers found that dark mode only has a significant impact on battery life under certain conditions.
When the brightness function is enabled by default, it will reduce battery consumption by 30-40% in most cases.
For phones with OLED screens, activating this mode saves on average 3-9% of battery power.
This percentage is so low that most users do not even notice that the battery is running out. But the lower the brightness when switching between modes, the greater the power-saving effect.
For example, when someone is sitting outside on a sunny day and watching a football match. His cell phone has an OLED screen and the auto-lighting function is activated. The phone screen may be too bright. If the phone uses the automatic brightness adjustment feature, the battery will be drained heavily.
Adjust brightness automatically to conserve battery life
According to research, it provides screen brightness at 100% and activated dark mode from 39% to 47%.
This means that this mode is activated when the screen is turned on. Compared to maintaining the light color mode, the battery life is much longer.
The study found that when using the Google News app on the Pixel 5, setting the brightness to 20% in bright mode consumes the same battery power as setting the brightness to 50% in bright mode.
So if you find the dark mode works for you, but you need a higher brightness for better vision. You don't have to worry about how much brightness you set as it doesn't greatly affect your phone's battery life.
