Battery Time

Helping users extend and save battery

During my time at Liquidum in 2016 many Android users struggled with short battery life and needed a simple way to extend usage time. Existing battery-saving apps were often cluttered with excessive features or had complex navigation, making them difficult to use. This created a clear opportunity to design a more intuitive, user-friendly solution that helped users optimize battery life effortlessly.

The goal was to create a streamlined, user-friendly battery-saving app that helped people extend their phone’s battery life effortlessly.

As the sole product designer, I was responsible for everything—from UI/UX design to branding, app icons, and even the marketing website. This was a chance to design not just an app, but an entire product experience.

Developing a one-tap interface

The app adjusts the system settings such as screen brigthess and more via a one-tap interface. It could also trigger automatically by location or wi-fi.

Created a distinct, engaging brand identity, including app icons and visuals that stood out.

The app successfully launched, giving Android users a simple and effective way to extend battery life. It saw strong early adoption, but since it was later removed from the store, its ratings and reviews are no longer publicly accessible.

This experience reinforced my ability to design full product ecosystems, shaping everything from UI/UX to branding and marketing.
