I got a good wallpaper... A plain black screen, such a battery saver, and the screen loves it!
Although, I do have an animation on lock screen.
I have a clock as my screensaver.... If you dl Google clock, "clock" appears in the choices in the screensaver menu... So it acts like my bedside clock when on the bedside on the Anker wireless charger.
Yes, ringtones and.my alarm clock alarm tune, does seem louder.
