Custom Image on Always-on Display auf Xiaomi
The Always-on Display on Xiaomi phones normally shows one of the pre-installed themes: a clock face, a calendar, or animated art. MIUI also lets you replace that theme with your own picture, so the screen shows a photo instead of a system design.
Where to find the custom image option
Open Settings ➔ Always-on display & Lock screen ➔ Always-on display ➔ Custom image. From there, tap Add from Gallery and choose a photo. Confirm with Apply after adjusting the extra options.
Before applying, MIUI shows a preview screen where you can move the clock, change its color, and decide whether battery percentage or notification icons stay visible on top of the image. These settings only affect the Always-on Display, not your regular lock screen wallpaper.
A custom image can increase power use compared to a simple clock theme, especially with bright colors that trigger more pixels to light up. If battery drain becomes noticeable, switching back to a themed clock design under the same menu is the better option.
