Google granted patent on new battery saving technology

2nd April 2013

Web giant Google has revealed that is has been granted a patent on its latest innovation to preserve and extend battery life on mobile devices run using it’s Android operating system.

The new technique being proposed can determine the power remaining in the battery of a battery-powered computer device that includes one or more processors and an organic light emitting diode (OLED) display.  It is able to change how much battery power the device is using to run on three different levels, based on three different stages of battery life.

The three stages get more extreme as the battery life depletes.  Stage one involves disabling the blur and animation functions of the OLED display.  Stage two involves building on stage one by also decreasing the resolution of images that can be displayed on the OLED display.  When battery level reaches a critically low level, stage three kicks in, building on the previous two stages to then command the OLED display to only use black and red colours.

This all works using some complicated technology that we would confuse ourselves even beginning to try and explain to you – but rest assured, it’s really really clever.  Previously smart phone owners have had to download specialist apps or take battery saving measures themselves, in order to extend the battery life of their device.  This is the first time it seems a smart phone will be able to have this battery saving function as a standard, and now Google owns the patent it seems like it could be yet another huge money spinner for the technological superpower.

Here’s a short diagram that goes a small way to explaining how the computer-implemented system works:
