NIX Solutions: Google’s New Energy-Saving Algorithm

The United States Patent and Trademark Office (USPTO) recently published a document outlining a new energy-saving algorithm for mobile devices developed by Google. While the algorithm resembles the familiar dark mode used in Android’s interface, Google claims it is more efficient in operation.

How the Algorithm Works

The core of the algorithm lies in the on-pixel ratio (OPR) indicator, which measures the number of active pixels on the display. The algorithm selectively activates only the necessary pixels on the OLED matrix—those where the user’s attention is focused—while keeping other areas unlit.

In simpler terms, it functions like an enhanced dark mode. Rather than merely dimming unused screen sections, the algorithm completely turns them off, similar to the Always-on Display (AoD) feature. Google has demonstrated this technology using the standard gallery app: the displayed image is slightly scaled, and the parts of the screen not covered by the picture remain entirely black. This targeted backlight control helps achieve significant energy savings.

At the moment, it’s uncertain when or if Google will integrate the patented technology into devices or expand its use to other applications, notes NIX Solutions. We’ll keep you updated on any future developments.
