Many people prefer it because it looks more elegant than the interface between white base and black text. Although it has other advantages.
Google has told developers it can save up to 60% on AMOLED screens by adopting dark mode in their apps.
Recently, according to Google, as dark mode is added to YouTube
When the brightness of the screen is 50%, it saves 14% of the battery in dark mode.
If the screen brightness is 100%, this mode can save 60% of the battery.
The reason is simple. The AMOLED screen does not need to turn on dark pixels, so consumption is greatly reduced.
As long as there is a dark mode option that uses an AMOLED screen, it is a good idea to choose whichever option you choose.
