The theme of black background can reduce the stimulation of the screen to the eyes, reduce eye fatigue, and make users more comfortable to use their mobile phones at night. Therefore, the black background of SMS appears to protect users' eyesight health.

Click the "More" icon in the upper right corner;

Select "Settings";

Just save the settings.

Does the theme of black background affect the power of mobile phone?

Compared with the white background theme, the black background theme can save a certain amount of electricity. Because under the theme of black background, there are fewer pixels to be lit on the screen of the mobile phone, and correspondingly, the power consumption will be reduced. In addition, the theme of black background can also reduce the stimulation of the screen to the eyes, reduce eye fatigue, and make users more comfortable when using the mobile phone.
