HP Introduces New Technology to Save Mobile Battery Life

Posted by CowboyNeal on from the batmax-beware dept.

fenimor writes "HP researchers have developed new technology to save battery life on mobile devices. Targeting one of the main culprits of battery consumption -- the display -- they've developed an energy-aware solution that dims parts of the screen that aren't in use. Display battery life lasts from two to 11 times longer, depending on what the user is doing."

    Now, this is the kind of thinking and research development that I would expect from HP! This technology combined with optimizations in the OS like Quartz could be a real boost to the way we interact with our portable devices, allowing for progressive dynamic layering of items that are important to view. Shoot, one could even link it into search engines to render only what is relevant for display.

    Now if they could just put a little innovation into their calculators again....

      While it would be incredibly cool if this technology could be used with PC LCD monitors, don't get too excited yet.

      LCD screens generally rely on a single backlight for illumination. Swithing to multiple backlights is certainly possible, but don't expect to be able to control power consumption on a pixel by pixelbasis anytime soon.

    Watch a typical Windows user sometime. What's the first thing they do to whatever application they open?

    If you said "Maximize it!", then you're right! Sadly, this ends up being self-defeating. :-/
