It’s been known for a long time that using dark wallpaper on devices with AMOLED screens can save energy and extend battery life.

Exactly how much you’ll save depends on the wallpaper, your device and how it’s used, but typical figures are 5 to 15%.

AMOLED mnml Wallpapers is a straightforward ad-free Android app which provides a host of minimalist wallpapers to explore.

Some are starkly simple, near monochrome, others are lighter and more colourful. Just looking at the categories available gives you an idea what they’ll contain: “Alien Hives”, “Flower”, “Geometric”, “Grid” and more.

The basic wallpapers are in 3200 x 2560 resolution. They can be cropped before applying, or you can download them for use anywhere.

Stylish, minimalist and power-saving wallpapers

The app is carefully optimised to reduce impact on your resources. The wallpapers are hosted online, and the preview images use a low quality level to minimise RAM use.

If you need more, full Muezi live wallpaper support gives you extra options and control. And although the basic app is entirely free, an XL version adds many more wallpapers up to 6400 x 5120 resolution for the best possible quality.

AMOLED mnml Wallpapers is available now for Android.
