Why use Dark Theme?
Dark Mode is a popular trend, both on desktop operating systems such as Windows 10, applications like Slack and mobile devices. There are several reasons why you want to use Dark Theme on your Android device. First of all, the eyes can be much easier to read everything, especially in dark environments. There is nothing more uncomfortable when the eyes are faced with a bright white light at night.
Moreover, if the smartphone has an OLED display, using Dark Mode can lead to a significant increase in battery life. The reason for this is explained by the fact that OLED displays turn off the pixels to display black, so they will not have to use battery power for some parts of the screen.
