Practice knows: setting the "energy saving" background for AMOLED screens has proven to be a miracle

The debate about AM OLEDs and LCD displays has been ongoing for a long time. When it comes to the "benefit" of AMOLED, most people will think of the "black background more power saving" for the first time. However, is this statement really reliable? The "theoretical basis" of this statement is actually quite simple, because LEDs require less current at the same brightness, and LED pixels on a pure black background are completely "turned off" (which means no backlight energy is needed) . In contrast, LCD screens always require a backlightâ€”even when black pixels are displayed.

In order to identify the authenticity of this statement, foreign media Greenbot specifically tested the latest Moto X (the machine is equipped with a 1080p AMO LED display ), and through an app to monitor the power consumption.

Subsequently, they specifically tested the Reddit Sync application's power usage in two different background modes. (As shown below)

In order to ensure the interference of other factors in the test, the tester specially killed the background task, turned on the mobile phone's flight mode, and kept the screen brightness at 50%. The final result is as follows.

This theory has been proven by practice to reduce energy consumption by switching a pure black background in the Reddit Sync application. Compared to the "full color" mode, the "energy saving mode" brings up to 41% difference in power consumption.

Of course, interested netizens can also take an hour or two to freely verify the theory at their leisure.
